Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil (零), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的).
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft.
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply (遵守) with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious , but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence (氣流).
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.

Hello! My name is Lisa, and I am a lioness. I live on the open grasslands of Africa with my family. Lions living in a group are called a pride.
My father is strong and powerful. He and his cousin are the leaders of our pride. The other members are my mother, her sisters, and their children.
The area where a pride lives is big! We roar (咆哮) to tell each other where we are and to warn strangers to stay away.
Meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped (有條紋的). As we grow older, the spots gradually disappear.
Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He’ll run around with a male (雄性的) friend or relative for a few years until they take over a pride of their own.
But for now, we have lots of fun together. We often play and fight for hours, which can help us practice skills that we will need for hunting.
We lions keep ourselves very clean. Just like a house cat, I clean my fur (毛) with my tongue. We clean for each other, too, to show we’re friends.
Lions like to sleep for most of the day. We hunt in the cool evening. Female (雌性的) lions hunt more often than male lions. We work together as a team. At the right moment, we attack and kill our prey. Then we share it. Male lions usually eat first. Females eat next. Baby lions are the last to eat. The smallest one gets the least food.
Since we are full, it’s time to go to find a nice place for a sleep. Bye!

Life in space will certainly take some getting used to！But the space station has been designed to keep the astronauts as comfortable as possible—the modules(艙) are roomy，bright，and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday，crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals，and 8.5 hours sleeping.Here are some other fun facts about life aboard the station：
Food
Come mealtime，astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions，astronauts could eat only freezedried food that didn’t require any preparation.But the space station is equipped with water，microwave ovens，and refrigerators，allowing the folks on board to eat more “normal” types of food，including fruit，vegetables，and ice cream!
Sleep
Each crew member has a private room.With no gravity，they’ll need to tie themselves to their beds，or they will float away！That might sound like a strange way to sleep，but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it，but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up，sit down or walk in space，so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this，astronauts on the station will exercise on bikes，rowing machines，and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U．S.shuttle or Russian rockets.But once they’re safe inside the space station，crew members can wear regular clothing.Of course，a specially designed，pressurized space suit is required for space walks.It has to withstand(經(jīng)受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble！Astronauts will use a freshwater hose(軟管) to take showers，shampoo，and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space？With a special “air toilet” that uses flowing air instead of water to dispose of waste.
【小題1】The facts about life in space are all mentioned EXCEPT ________.
| A．clothing | B．entertainment |
| C．sleep | D．exercise |
| A．The temperature is quite different in different places in space. |
| B．Astronauts must wear special space suits all the time in space. |
| C．Astronauts can wear regular clothing for space walks now. |
| D．Astronauts wear pressurized space suits just to keep warm. |
| A．It can make astronauts feel relaxed in space. |
| B．It can help astronauts spend their spare time happily. |
| C．Astronauts’ lives are more important in space than on earth. |
| D．It can prevent astronauts from causing muscle and bone loss. |
| A．Astronauts could eat apples in space in the past. |
| B．Astronauts eat only fruit，vegetables and ice cream now. |
| C．Fresh food isn’t available to astronauts in space. |
| D．Space food is getting better now than before. |

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陳代謝) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (監(jiān)控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的衛(wèi)星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
【小題1】European researchers are conducting hibernation experiments to ________.
| A．ensure astronauts to get a complete sleep |
| B．find the secret of some creatures |
| C．make preparations for the journey to Jupiter’s moon Callisto |
| D．know if man can sleep for years |
| A．Science fiction is people’s imagination. |
| B．Science fiction is imaginative, but it can be realized. |
| C．Things seem impossible may come true. |
| D．Things described in science fiction are sure to become true. |
| A．putting living cells into a sleep-like state is full of failure |
| B．Biggiogera is confident with the experiment |
| C．human’s hibernation needs no energy |
| D．medical research is the key to space flight hibernation system |
| A．Six humans to fly to Callisto |
| B．Human hibernation improves health |
| C．Space travel attracts people |
| D．Deep sleep for deep space travel |

It's going to be a chaotic(混亂的)day. How do I know? It’s Monday. OK, joking. But, I do predict that today will be filled with the normal last-minute tasks, fire drills, and unforeseen events. So, how do you keep yourself from being swept away in the stream of chaos? How do you remain calm while others are rushing and panicking? There's a problem… Panic! When things don't go as planned, how do you react? Are you the calm one who works to fix things? Or the one running around like Chicken Little screaming that the sky falling? Getting upset or alarmed can seem like natural reactions to a problem.
Here are a few tips to kelp you remain calm in the face of the storm:
? Don't Panic You are better able to find a solution if you aren't panicking. If you can keep your head when others are losing theirs, you will be able to make a dear decision in the chaos.
? There Aren't Many True Emergenaes My time as a Naval Officer taught me about true emergencies. In the military, when there is a problem, people can get hurt or die. This is not usually the case when the office copier or email server goes down. Keep things in perspective. There are very few true emergencies in life.
? Avoid the "Fight or Flight" When you are stressed, your body will want to go into "fight or flight." Your body was designed to keep you safe from danger, but its natural reflexes aren't always the best solution against a project gone away. Keep your emotions in check and ensure that your physical reflexes don’t make bad decisions for you.
? Head Into The Problem While everyone else is running away, true leaders walk into a problem. Sticking your head in the sand only makes things worse. Instead of trying to ignore the situition, get to the heart of the issue as soon as possible. Only then can you address it
How Will You React? When you find yourself ready to lose it, take a step back. Ask, "In this truly an emergcncy?" Keep your head when others are losing theirs. And you'll find that you are that much closer to a solution.
【小題1】The author writes the first paragraph in order to______.
| A．describe a chaotic day | B．a(chǎn)dvocate a way of life | C．introduce a topic | D．make a joke |
| A．low your head | B．keep your head | C．shake your head | D．stick your head |
| A．there are seldom true emergencies in life |
| B．there are many true emergencies in life |
| C．some emergencies are really urgent |
| D．some emergencies can't be predicted |
| A．Fight or Flight |
| B．True emergencies |

Most people know that awkward feeling when you walk into an elevator with other people and try not to make eye contact(接觸). But a new research suggests it may be down to a subconscious power struggle being played out as you make your way up and down.
A study found that people decide where they stand based on a micro social status，established within seconds of entering the lift.
Rebekah Rousi．a(chǎn) Ph. D．student in cognitive(認(rèn)知)science，conducted an ethnographic(人種論)
Study of elevator behaviour in two of the tallest office buildings in Adelaide，Australia.As part of her research，she took a total of 30 lift rides in the two buildings，and discovered .There was an established order to where people tended to stand
In a blog she writes that more senior men seemed to direct themselves towards the back of the elevator She said：“In front of them were younger men，and in front of them were women of aII ages.”She also notice there
was a difference in where people directed their gaze(注視)half way through the ride．“Men watched the monitors，looked in the side mirrors(in one building)to see themseIves．And in the door mirrors(of the other building)to also watch others Women would watch the monitors and avoid eye contact with other users(unless in conversation)and the mirrors，”she writes．
She concluded it could be that people who are shyer stand toward the front，where they can’t see other passengers，whereas confident people stand in the back，where they have a view of everyone else.
【小題1】The passage is mainly about
A. elevator riding manners
B communication in the elevator
C. elevator riders’ standing positions
D. micro social status in the elevator
【小題2】The underlined word“it”in the first paragraph probably refers to“ ”
| A．a(chǎn)n elevator | B．the new research | C．eye contact | D．social status |

October 15th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donors（捐贈者） will give 150,000 bars of soap to schools in Ethiopia.
Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children’s Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(細(xì)菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub（揉搓） it into all areas, including under the fingernails（指甲）. Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.
The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect（感染）themselves by touching their eyes, noses or mouths. Then they can infect others.
【小題1】What’s the best title for this passage?
| A．Say no to washing hands in the wrong way. |
| B．Find out why washing hands carefully is so important. |
| C．Hand washing: so important----it gets a day of its own. |
| D．Want to live a longer life?-wash your hands. |
| A．to dry your hands | B．to wash away the soap |
| C．to rub your hands carefully | D．to clean your fingers |
| A．how to wash your hands correctly |
| B．why washing hand with soap is so important |

The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蟻堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通風(fēng)口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature changes—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its hot summers and cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled.
【小題1】Why was Eastgate cheaper to be built than a conventional building?
| A．It was designed in a smaller size. |
| B．No air conditioners were fixed in. |
| C．Its heating system was less advanced. |
| D．It used rather different building materials. |
| A．Fresh air from outside. | B．Heat in the building. |
| C．Hollow space. | D．Baseboard vent. |
| A．New York has less clear skies as Harare. |
| B．Its dampness affects the circulation of air. |
| C．New York covers a larger area than Harare. |
| D．Its temperature changes seasonally rather than daily. |
| A．a(chǎn)llows a wide range of temperatures |
| B．functions well for most of the year |
| C．can recycle up to 30% of the air |
| D．works better in hot seasons |

BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips（微芯片） and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically（國內(nèi)的） developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.
【小題1】What’s the best title for this passage?
| A．The Arrival of Chinese Supercomputers |
| B．Homemade CPUs with a Long Way to Go |
| C．The Supercomputers of Three Organizations in China |
| D．Homemade CPUs on the Way for Local Supercomputers |
| A．Dawning 6000 | B．Loongson microchips |
| C．DIIC | D．Tianhe-1A |
