Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide(一氧化碳), 45% of the nitrogen oxides(氮氧化合物), and 34% of the hydrocarbon (碳?xì)浠衔? pollution in the United States can be traced directly to automobile exhausts (廢氣). In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water.
In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents (成分) of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides.
California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent.
小題1:The author uses figures in Paragraph 1 ________.
A.to reflect the rapid growth of automobile use
B.to highlight the importance of environment protection
C.to show the consequence of automobile exhausts
D.to criticize the low quality of cars
小題2:How are nitrogen oxides formed according to the text?

小題3:Which of the following is NOT true according to the text?
A.Carbon monoxide can be controlled in the engine.
B.Smog will form when hydrocarbons meet nitrogen oxides in the sunlight.
C.Hydrocarbons have no poisonous character themselves.
D.The conditions that decease emission of hydrocarbons will increase emission of nitrogen oxides.
小題4:According to the text, alcohol is added to gas in order to ______.
A.increase awareness of environment protection
B.control air pollution
C.increase the fuel efficiency
D.replace gas gradually

Sigmund Freud was one of the first scientists to make serious research of the mind. The mind is the collection of activities based in the brain that involve how we act, think, feel and reason.
He used long talks with patients and the study of dreams to search for the causes of mental and emotional problems. He also tried hypnosis(催眠術(shù)). He wanted to see whether putting patients into a sleep-like condition would help ease troubled minds. In most cases he found the effects only temporary.
Freud worked hard, although what he did might sound easy. His method involved sitting with his patients and listening to them talk. He had them talk about whatever they were thinking. All ideas, thoughts and anything that entered their mind had to be expressed. There could be no holding back because of fear or guilt.
Freud believed that all the painful memories of childhood lay buried in the unconscious self. This part of the mind he said contains wishes, desires and experiences too frightening to recognize.
He thought that if these memories could somehow be brought into the conscious mind, the patient would again feel the pain. But this time, the person would experience them as an adult. The patient would feel them, be able to examine them and, if successful, finally understand them.
Using this way, Freud reasoned, the pain and emotional pressure of the past would be greatly weakened. They would lose their hold over the person's physical health. Soon the patient would get better.
Many of Freud's theories about how the mind works also had strong sexual connections. These included what he saw as the repressed feelings of sons toward their mothers and daughters toward their fathers.
If nothing else, Freud's ideas were revolutionary. Some people rejected them. Many others came to accept them. But no one disputes his great influence on the science of mental health.
小題1:How many methods did Sigmund Freud use to study the mind?
A.One.B.Two.C.Three.D.Four.
小題2:Sigmund Freud’s research was difficult because ______.
A.he had to work hard and have patients talk freely
B.he had to live with people who had troubled minds
C.he had to listen to unhappy stories of different people
D.he had to give his patients a sense of security
小題3:Sigmund Freud held the idea that the painful memories of childhood ______.
A.could be forgotten forever
B.could have a life-long influence
C.could become wises and desires
D.could be understood unconsciously
小題4:If an adult parent feels the memories of childhood painful, the patient would probably ______.
A.have physical and mental problems
B.be greatly influenced by them
C.have a better understanding of life
D.have a healthier and happier life

Our environment isn’t as green and beautiful as it should be. There are steel monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth.
You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “ accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.
At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps(水龍頭)are not leaky(泄露的),which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs.
Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.
Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.
With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.
小題1:The underlined word “scrimping” in the third paragraph can be replaced by _____.
A.savingB.cleaningC.cookingD.drinking
小題2:From the fifth paragraph, we can know that ________.
A.protecting the environment begins with small chores
B.protecting the environment should start from childhood.
C.wonderful life comes from environmental protection
D.protecting the environment benefits the country and the people
小題3:Which of the following isn’t true?
A.The more people do their part, the greener the environment will be.
B.Selling what you don’t want any more is a kind of recycling.
C.To protect the environment may help you save some money.
D.Your bad habits for the environment are a valuable contribution.
小題4:Which of the following can be the best title for this passage?
A.The Use of Garbage Dustbin
B.How to Save Water and Electricity
C.How to Save the Environment
D.Our Current Environmental Problems

In South America, the rich soil of the Amazon River basin(流域)in Brazil is known as “black gold”. Scientists found that the secret of this rich soil was charcoal(木炭). Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago.
Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years.
Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks(莖), small pieces of wood and poultry waste into “biochar”(生物碳). They reported their findings at a recent meeting of the American Chemical Society in New Orleans.
Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive(集約的) farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground.
The researchers planted winter wheat in containers of soil in a greenhouse — some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity.
The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations.
Next, the team will carry out a five-year study of biochar with spinach(菠菜), green peppers and tomatoes.
Mingxin Guo says he learns about the “black gold” in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960’s. But it was not until recent years that scientists began to bring public attention to it.
小題1:According to the passage, which of the following statements is TRUE?
A.The researchers will go on proving their theory.
B.The leading researcher learns the theory from the magazine.
C.Charcoal was discovered 1,500 years ago.
D.Common farming can produce more carbon dioxide.
小題2:Biochar has the following advantages EXCEPT that ________.
A.it can improve the condition of the soil
B.it can be used as a kind of energy
C.it can help against global warming
D.it can increase productivity of the corn
小題3:According to the research, the biochar can help against global warming because it can ________.
A.reduce the carbon dioxide
B.keep the carbon in the soil
C.reduce the loss of nutrients in the soil
D.a(chǎn)bsorb the carbon dioxide
小題4:Which of the following can be the best title of the passage?
A.Using Charcoal to Make soil into “Black Gold”
B.Using Charcoal to Reduce the Carbon Dioxide
C.How Amazon River Basin Produces “Golden Black”
D.Guo’s Research on Producing Biochar

LIKE many teachers, Cristi Derow and Jennifer Bradley have spent most of their careers giving classroom lectures to students who sat passively in their seats.
The Lewisvillle, Texas, school teachers were aware that the hours they spent on preparing lessons were too often wasted on many students. So Forestwood High School, Texas, used the “flipped (翻轉(zhuǎn)的) classroom” method of instruction. “We’ve completely done away with our lecture,” Derow said. And homework assignments “are all done in class,” Bradley said.
With the flipped concept, a student’s usual homework assignment is to watch pre-recorded lectures on their computers or smart phones.They walk into class ready to discuss the topic, collaborate(合作) with other students and work on assignments based on what they learned from the video. Free from lecturing, the teachers can use class time to look deeper into the subject and focus on difficult concept. As students change from a passive to an active role, they learn critical thinking skills, learn to collaborate and become independent learners.
Instead of doing homework assignments alone at home, students are now “working together, talking about it,” Bradley said. “If they don’t agree on an answer, they debate it and have to justify their answers. It’s a higher level of learning.”
Her students give the flipped classroom high marks.
Sarah Lee, 14, watches the 30-minute videos on a home computer. She likes the ability to rewind the tapes if she doesn't understand a concept. She also likes being able to watch the lessons on her own schedule.
One of her classmates, Dawson Depperschmidt has the same idea and thinks the time she spends in the classroom is more productive. “It gives us more time to learn at school,” Dawson said. “You get more in-depth in class.
小題1:What can we conclude from the first two paragraphs?
A.Teachers in Lewisville enjoyed giving classroom lectures.
B.It takes time for students to concentrate and understand in class.
C.Many students took an inactive part in lecture-style classes.
D.Teachers in Lewisville found that there was no need to prepare lessons.
小題2:What difference does the “flipped classroom”method make to students?
A.They have more arguments with classmates.
B.They have to be independent and cooperative.
C.They need to do more homework at home.
D.They have to prepare lectures by themselves.
小題3:What does the underlined word “productive” mean?
A.reducing difficultiesB.trying new methods
C.a(chǎn)chieving a lotD.causing troubles
小題4:What are the benefits of the “flipped classroom” method?
a. Teachers have time to solve deeper problems
b. Students are engaged in a higher level of learning.
c. Students study according to their own schedule.

We all make excuses.
But the successful ones are those who can kill the excuses like the miserable maggots they are.
I’m too tired. I don’t have the time. I don’t feel motivated. I’d rather do nothing. I don’t have the money, equipment, space. I can’t because …
We’ve all made the excuses. Here’s how to kill them.
See the positive. Excuses are usually made because we don’t feel like doing something — we’re accentuating the negative. Instead, see the fun in something, the joy in it. And maintain a positive attitude, or you’ll never beat the excuses.
Take responsibility. Excuses are ways to get out of owning up to something. If we don’t have the time, money, equipment, etc., then it’s not our fault, right? Wrong. Take responsibility, and own the solution.
Find a solution. Just about every problem has a solution. Don’t have time? Start with just 5-10 minutes. Make the time. Wake earlier. Do it during lunch. Don’t have the energy? Do it when you have higher levels of energy. You’re smart. Figure out the solution.
See your goal. This is your motivation — your reason for doing it. Sure, you could just lay on the couch, but if you think about why you really want to pursue a goal, you’ll be motivated. Visualize that goal and just get started.
Be accountable. Have a workout partner, a project partner, a team, someone to report to. If you have to meet a coach or partner, you’re more likely to do something.
Watch this. Then go an do it.  
小題1:How many tips mentioned in the text to prevent excuses?
A.FourB.ThreeC.SixD.Five
小題2:The second paragraph is developed mainly by _______
A.providing common examples.
B.following the order of time.
C.making comparisons of excuses.

A.to view the outline of something by means of an X-ray.
B.to weaken or spoil the quality or efficiency of something.
C.to form a mental image of something incapable of being viewed.
D.to express the formal image of something capable of being seen.
小題4:Why do you need a partner according to the passage?
A.because you are likely to make a report to someone.
B.because it’ll be more possible for you to do something wih a partner.

Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment. ”
Astronomers—scientists who study stars and planets—-have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(遷徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers. ”
Countless more animals casualties(傷亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.
小題1: What is the author concerned about according to Paragraph 4?
A.Birds may take other migration paths
B.Animals’ living habits may change suddenly
C.Varieties of animals will become sharply reduced
D.Animals’ survival is threatened by outdoor lighting
小題2:Lighting regulations in Flagstaff, Arizona are put into effect to
A.Lessen the chance of getting cancer
B.create an ideal observation condition
C.ensure citizens a good sleep at night
D.enable all creatures to live in harmony
小題3: What message does the author most want to give us?
A.Saving wildlife is saving ourselves
B.Great efforts should be made to save energy
C.Human activities should be environmentally friendly
D.New equipment should be introduced for space study

BEIJING (AP) — Sandstorms whipping across China shrouded(遮蔽) cities in an unhealthy cloud of sand Monday, with winds carrying the pollution outside the mainland as far as Hong Kong and Taiwan.
It was the latest sign of the effects of desertification: Overgrazing, deforestation, urban sprawl(無計(jì)劃地?cái)U(kuò)展) and drought have expanded deserts in the country's north and west. The shifting sands have gradually moved onto populated areas and worsened sandstorms that strike cities, particularly in the spring.
Winds blowing from the northwest have been sweeping sand across the country since Saturday, affecting Xinjiang in the far west all the way to Beijing in the country's east. The sand and dust were carried to parts of southern China and even to cities in Taiwan, 1600 miles (2600 kilometers) away from Inner Mongolia where much of the pollution originated.
The sandstorm in Taiwan, an island 100 miles (160 kilometers) away from the mainland, forced people to cover their faces to avoid breathing in the grit(砂礫) that can cause chest discomfort and respiratory problems even in healthy people. Drivers complained their cars were covered in a layer of black soot in just 10 minutes.
In Hong Kong, environmental protection officials said pollution levels were climbing as the sandstorm moved south. Twenty elderly people sought medical assistance for shortness of breath, Hong Kong's radio RTHK reported.
The latest sandstorm was expected to hit South Korea on Tuesday, said Kim Seung-bum of the Korea Meteorological Administration. The sandstorm that raked(掠過) across China over the weekend caused the worst "yellow dust" haze in South Korea since 2005, and authorities issued a rare nationwide dust advisory.
Grit from Chinese sandstorms has been found to travel as far as the western United States.
China's Central Meteorological Station urged people to close doors and windows, and cover their faces with masks or scarves when going outside. Sensitive electronic and mechanical equipment should be sealed off, the station said in a warning posted Monday on its Web site.
State television's noon newscast showed the tourist city of Hangzhou on the eastern coast, where graceful bridges and waterside pagodas were hidden in a mix of sand and other pollution. In Beijing, residents and tourists with faces covered scurried along sidewalks to minimize exposure to the pollution.
A massive sandstorm hit Beijing in 2006, when winds dumped about 300,000 tons of sand on the capital.
小題1:We can learn from the text that           .
A.the sandstorms were purposely made by China.
B.the writer thinks that China government should be responsible for the pollution.
C.the sandstorms badly affected the air in US.
D.China's Central Meteorological Station will be closed.
小題2:The passage tells us that the sandstorms mainly came from      .
A.XinjiangB.HangzhouC.BeijingD.Inner Mongolia
小題3:The underlined word, “respiratory” (in Para.4) means         .
A.breathingB.digestingC.hearingD.walking
小題4:Which of the following statements is NOT true?
A.South Korea seldom issues nationwide dust advisories.
B.Taiwan is 1,600 miles from Beijing.
C.Sandstorms have hit Beijing more than once.
D.In Hong Kong some old people need help for shortness of breath caused by sandstorms.
