Boiler rooms are often dirty and steamy, but this one is clean and cool. Fox Point is a very new47-unit living building in South Bronx, one of the city’s poorest areas. Two-thirds of the people living there are formerly (以前) homeless people, whose rent is paid by the government. The rest are low-income families.  The boiler room has special equipment, which produces energy for electricity and heat. It reuses heat that would otherwise be lost to the air, reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladian, a group that specializes in providing housing and services to needy, people. Palladian received support from Enterprise Community Partners (ECP), which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (環(huán)境方面) clever and affordable homes which are called, the Green Communities Standards. These standards include water keeping, energy saving and the use of environmentally friendly building materials.  Meeting the standards increases housing construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a window to get most daylight can help save energy.
Michael. Bloomberg, New York's mayor, plans to create 165,000 affordable housing units for500,000 New Yorkers. Almost 80% of New York City’s greenhouse-gas emissions come from buildings, and 40% of those are caused, by housing. So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD) , whose duty is to develop and keep the city’s supply of affordable housing, will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York’s DHPD is the largest city developer of affordable housing in the country.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less useable fresh water. A major part of the  water we use every day is groundwater. Groundwater does not come from lakes or rivers.It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts than areas with more rainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.
You can take steps to save water in your home.To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?

A．Using river water. B．Throwing batteries away.
C．Paving parking lots. D．Throwing rubbish into lakes.
【小題2】What can be inferred from the text?
A．All water shortages are due to human behavior.
B．It takes a lot of effort to meet our water needs.
C．There is much we can do to reduce family size.
D．The average family in America makes proper use of water.
【小題3】The last paragraph is intended to________.
A．show us how to fix leaks at home
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us
D．suggest what we do to save water at home
【小題4】The text is mainly about________.
A．why paving roads reduces our water
B．how much we depend on water to live
C．why droughts occur more in dry climates
D．how human activity affects our water supply

You might not know it, but there is something wonderful at your fingertips. You can make people happier, healthier and more hard-working just by touching their arms or holding their hands.
Doctors say that body contact is a kind of medicine that can work wonders. When people are touched, the quantity of hemoglobin (血紅蛋白)－a type of matter that produces the red color in blood increases greatly. This results in more oxygen reaching every part of the body and the whole body benefits. In experiments, bottle-fed baby monkeys were separated from their mothers for the first ten days of life. They became sad and negative. Studies showed the monkeys were more probable to become ill than other babies that were allowed to stay with their mothers.
Human babies react in much the same way. Some years ago, a scientist noticed that some well-fed babies in a clean nursery became weak. Yet babies in another nursery were growing healthily, even though they ate less well and were not kept as clean. The reason, he concluded, was that they often had touches from nurses.         
Experiments show that most people like being touched. And nearly all doctors believe touch helps to reduce patients' fear of treatment. Of course there is time when a touch is not welcome. But even if we don't like being touched, a smile can make us feel better. Smiling increases blood flow and starts the production of "happy brain" chemicals. So let's have a big smile and don't forget to keep in touch.
【小題1】Which of the following is NOT true?

A．Everyone knows that body contact can make people happier.
B．People may work harder because of body contact.
C．Your fingertips can do something.
D．People may not understand the importance of touching.
【小題2】According to the passage _____.
A．human brains need oxygen and blood supply now and then
B．touches from doctors and nurses have nothing to do with treatment
C．new-born baby monkeys should stay away from their mothers
D．not all the people like being touched
【小題3】The word "benefits" in the second paragraph probably means _____.
A．to be useful or helpful
B．to get something useful or helpful
C．to be ill
D．to be hurt
【小題4】The best title for the passage might be _____.
A．Why People Touch B．Smile and Touch
C．Wonders of Touch D．Touch or Not

Throughout the world, boys and girls prefer to play with different types of toys. Boys typically like to play with cars and trucks, while girls typically choose to play with dolls. Why is this? A traditional sociological explanation is that boys and girls are socialized and encouraged to play with different types of toys by their parents, peers, and the “society”. Growing scientific evidence suggests, however, that boys’ and girls’ toy preferences may have a biological origin.
In 2002, Gerianne M. Alexander of Texas A&M University and Melissa Hines of City University in London surprised the scientific world by showing that monkeys showed the same sex-typical toy preferences as humans. In the study, Alexander and Hines gave two masculine toys (a ball and a police car), two feminine toys (a soft doll and a cooking pot), and two neutral toys (a picture book and a stuffed dog) to 44 male and 44 female monkeys. They then assessed the monkeys’ preference for each toy by measuring how much time they spent with each. Their data showed that male monkeys showed significantly greater interest in the masculine toys, and the female monkeys showed significantly greater interest in the feminine toys. The two sexes did not differ in their preference for the neutral toys.
If children’ s toy preferences were largely formed by gender socialization, as traditional sociologists’ claim, in which their parents give “gender appropriate” toys to boys and girls, how can these male and female monkeys have the same preferences as boys and girls？They were never socialized by humans, and they had never seen these toys before in their lives.
【小題1】Traditional sociologists believe boys’ and girls’ toy preferences ________.

A．a(chǎn)re passed down from their parents 
B．a(chǎn)re largely formed in later life 
C．have nothing to do with gender socialization 
D．have a biological origin 
【小題2】The study by Alexander and Hines shows that monkeys________.
A．a(chǎn)lso have a sex typical toy preference 
B．a(chǎn)lso play toys as humans do 
C．have no toy preferences 
D．like to play different toys at different time 
【小題3】Alexander and Hines carried out the study to ________.
A．find more evidence for traditional sociology 
B．test the intelligence of monkeys 
C．test whether monkeys like to play toys 
D．find out why boys and girls prefer different toys 
【小題4】According to the study, if given a stuffed dog, ________.
A．only the male monkeys showed interest 
B．the female monkeys showed more interest 
C．the male and female monkeys showed the same interest 
D．neither the male nor the female monkeys showed any interest

Will online courses transform world of education?
Some may wonder what it feels like to attend a class at Stanford University. The recently popular MOOCs (Massive Open Online Courses) can satisfy this desire. But they are also most likely to change the situation of higher education. Only last month，both Peking University and Tsinghua University announced plans to start open online course on the edX platform，one of the world’s major providers of MOOCs，to explore this new form of online education.
Gaining momentum(勢(shì)頭)
“It’s not only a change of platforms from offline to online. It’s more about a reform of
teaching methods，even the whole education system，”said Chen Jining，president of Tsinghua University.
The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence，taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled(注冊(cè)) students in 200 countries. According to Nature magazine，by June 2013，74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University，explains the appeal of MOOCs as a simple case of supply and demand：“The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs，in which classes usually taught by top teachers are available to everyone，”said Lu.
Too early to replace
With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers，because hardly any universities offer degree certificates, as college administrators point out, it’s difficult to confirm if students are foaming anything in MOOCs，reposed USA Today．
The Wall Street Journal also reposed that，presently，a typical MOOC student is likely to have
already graduated from college and is using the course to explore an interest or acquire professional
skills. Even so, an increasing number of undergraduates are signing up.
“What we are really establishing(創(chuàng)建)are educational pathways for people who want skills that are related to contemporary jobs，”Thrun told The Wall Street Journal．
【小題1】MOOCs have been considered likely to reform education since___________．

A．the founding of Udacity
B．the wide application of online education
C．the popularity of the course Artificial Intelligence
D．the opening of MOOCs on the edX platform in China
【小題2】According to Lu Fang, MOOCs have become popular because___________．
A．high quality educational resources are in demand
B．students can attend courses in famous universities
C．college students have access to famous teachers
D．MOOCs have brought about revolution in education
【小題3】What can we learn from the passage?
A．Most of the MOOCs focus on professional training for college graduates．
B．There are barriers for MOOCs to replace the present education system．
C．International companies prefer applicants who graduate from MOOCs．
D．More and more undergraduates have realized the limits of MOOCs．
【小題4】The author’s attitude towards MOOCs is___________．

When 18th-century scientists first came across Australia’s platypus(鴨嘴獸), they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal.
While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (針鼴鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鱷魚(yú)), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
【小題1】 What can we learn about the platypus according to the text?

A．It has a lower body temperature than other mammals.
B．It only closes its eyes when underwater.
C．It’s the only poisonous mammal in the world.
D．It feeds its young on wild animal meat.
【小題2】Which of the following is NOT used as a comparison with the platypus in the text?
A．The crocodile. B．The echidna. C．The duck. D．The dog.
【小題3】The following characteristics of the platypus have been described in the text EXCEPT ________.
A．its natural enemy B．its appearance
C．its walking pose D．its daily diet
【小題4】We can infer from the last paragraph that the platypus _______.
A．is hunted for its meat B．is in danger of extinction
C．is endangered by air pollution D．is well-protected now
【小題5】Which of the following would be the best title for this text?
A．Platypus, a Trick?
B．Platypus, the Only Warm-Blooded Mammal
C．The Characteristics of Platypus
D．The Strange Mammal —Platypus。

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （紅外線）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （殺蟲(chóng)劑）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害蟲(chóng)）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.
【小題1】 Plants will emit an increased amount of heat when they are______________.

A．sprayed with pesticides
B．facing an infrared scanner
C．in poor physical condition
D．exposed to excessive sun rays
【小題2】．In order to apply pesticide spraying precisely, we can use infrared scanning to____________.
A．estimate the damage to the crops
B．measure the size of the affected area
C．draw a color-coded map
D．locate the problem area
【小題3】 Farmers can save a considerable amount of pesticide by______________.
A．resorting to spot-spraying
B．consulting infrared scanning experts
C．transforming poisoned rain
D．detecting crop problems at an early stage
【小題4】 The application of infrared scanning technology to agriculture met with some difficulties
_______________.
A．the lack of official support
B．its high cost
C．the lack of financial support
D．its failure to help increase production
【小題5】 Infrared scanning technology may be brought back into operation because of_____________.
A．the desire of farmers to improve the quality of their produce
B．growing concern about the excessive use of pesticides on crops
C．the forceful promotion by the Department of Agriculture
D．full support from agricultural experts

Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留）into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. "The brain is not passive while you sleep. It's quite active. You can do quite a lot of things while you are asleep."
But the results don't mean that Spanish vocabulary tapes now have a place on the nightstand. L, Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster（垃圾車(chē)）in July knows, smells can cause a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale. But scent of fresh bread causes a long, deep inhale.、rzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers' noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or meat, was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.
【小題1】We can infer from the passage that

A．while sleeping, we can learn whatever we want to learn
B．we will increase the size of inhale if we catch a pleasant smell
C．the knowledge we learned while sleeping will be forgotten in the next waken day
D．when walking by a bakery, the fresh bread will cause a nose-jerk reaction
【小題2】What is Paragraph 3 mainly about?
A．One can’t acquire complicated knowledge during the sleeping hours.
B．Spanish vocabulary tapes now have a place on the nightstand
C．Researchers have tried to find evidence that the new words can be learned during sleep.
D．Complicated information can make its way into the brain during sleep
【小題3】How do Arzi and her team do their research? By
A．giving instructions B．a(chǎn)nalyzing human brains
C．following the guides of others D．doing experiments
【小題4】In which part of a website may this passage most likely appear?
A．Culture. B．Science. C．History. D．Economy.

The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology（納米技術(shù)）, which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology（微電子技術(shù)）we use, such as the silicon chips of computers.
Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases.
The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this “absence of evidence” is not being taken as “evidence of absence”. In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods.
One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle（顆粒）size that should concern us, but its functionality. Take gold, for example, which is a famously inert (惰性) substance, and valuable because of it. It doesn’t rust or corrode because it doesn’t interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface area of many pea-sized balls with the same weight of the single basketball. The pea-sized balls have a surface area many hundreds, indeed thousands of times bigger than the basketball, and this allows them to interact more easily with the environment. It is this increased interactivity that changes their functionality—and makes them potentially more dangerous to health or the environment.
【小題1】Why does the writer mention microtechnology in the first paragraph?

A．to introduce the topic of nanotechnology
B．to help us better understand nanotechnology
C．to help us know more about microtechnology
D．to compare microtechnology with nanotechnology
【小題2】The example of the “gold” in the last paragraph is intended to show that_________.
A．gold is valuable because it is an inert substance
B．a(chǎn)n inert substance like gold doesn’t interact with water or oxygen
C．the function of gold is steady because it is an inert substance
D．the function of gold changes when made into something very small
【小題3】Which process explains that there might be risks in nanotechnology?
A．expand surface area →increase interactivity → change functionality→cause possible dangers
B．expand surface area → change functionality → increase interactivity →cause possible dangers
C．increase interactivity → expand surface area → change functionality→cause possible dangers
D．increase interactivity → change functionality → expand surface area→cause possible dangers
【小題4】What does the passage mainly focus on?
A．the introduction of nanotechnology and its wide use
B．the present use of nanotechnology and its future
C．the potential danger nanotechnology may bring us
D．the proposal to stop nanotechnology due to the potential danger
