6.When thinking about placing a human being in space,one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment.The cold of space will freeze skin in a short time.The fierce heat of the sun can cause serious burns.The lack of atmosphere can cause gases in the body to expand(扩大) and even burst.With no oxygen to breathe,a human being will die in only a few moments.Radiation from the sun is another risk in space.So is damage from small pieces of rock and objects like meteoroids (陨石).
In 1933,an American flyer,Wiley Post,designed one of the first successful devices to protect a pilot at extreme heights.It was a large device that looked like a can surrounded the pilot's head.Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s.The clothing was similar to that invented by Wiley Post.
Today,astronauts wear very different protective clothing.It lets them move,do useful tasks,and stay outside their spacecraft in comfort and safety for several hours.The spacesuit is called the shuttle extravehicular mobility unit or EMU.It was designed to endure longer and to permit more movement than earlier spacesuits.
The EMU has a number of parts that an astronaut can link together by using only one hand,which makes it possible for each astronaut to select the parts that fit correctly.
Nowadays,NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars.Because of the gravity on Mars,spacesuits may have to be designed to be lighter than suits used in orbit or on the moon.The equipment may also have to protect astronauts from dust carried in the winds on Mars.And,they must be easy to repair and keep clean during a longer flight to and from the red planet.
32.Which of the following is NOT mentioned about the dangers of space environment?C
A.Lack of oxygen.
B.Fierce heat from the sun.
C.Gases in the body.
D.Radiation from the sun.
33.Which of the following statements is true,according to this passage?B
A.Wiley Post designed the first protective clothing for astronauts.
B.Astronauts in earlier spacesuits had difficulty in moving,doing useful tasks and so on.
C.EMU has many parts that can be linked together by using two hands.
D.Special spacesuits have been used for exploration of the planet Mars.
34.The underlined word"endure"meansC.
A.provide     B.move     C.last    D.live
35.The best title of the passage might beD.
A.Space explorationB.Astronauts'flights
C.The Advantages of Spacesuits D.The Development of Spacesuits.

16.It's long been known that dogs and cats,with their well developed sense of smell,can be trained to identify the chemicals released by human illnesses.In some cases,researchers have even trained household pets to detect or predict epilepsy(癫痫病).But what if we could put the sense into a microchip(芯片),allowing us to create a breathalyzer(呼吸分析器) for diseases?
For Dr.Andrew Koehl,the inventor of the microchip technology at the heart of this digital nose,the technology that will allow us to do just that is already here."We can detect down to parts per billion levels,"Koehl says."To give you a similarity that's equal to one drop in an Olympic size swimming pool."The sensor(感应器) identifies each chemical's make-up in the air.If the sensor is set to a certain level,it will set off an alarm.
Work continues to make it smaller and makes it able to enter the healthcare market.Within several years,the company hopes to develop it as a diagnostic(诊断) tool"What's amazing is that there really are chemicals on your breath that indicate illness.That's been shown though a number of studies and we can detect those,"he said."There have already been a number of research papers published suggesting we can detect many disease."
At the beginning,the technology had been developed for defense purposes.He said the terror caused by the events of September 11had got him thinking about the application of this type of sensor in safety check."Originally it was aimed at detecting things like explosives,poisonous chemicals and other terrors that might occur,"said Dr Koehl.
Eventually the sensor could become a part of many everyday instruments,warning users of which foods are going bad in the fridge or even the best moment to take the roast out of the microwave oven.
You could even,one day,have a digital nose that you could carry in your pocket."More recently we've been looking at user spaces so we're talking to a number of producers of mobile phones and mobile phone parts,"he said."We want to develop a module small enough to put into mobile devices(装置) like phones."

24.It can be inferred from the passage thatC.
A.This type of sensor was designed to prevent disease at first
B.The digital nose can be put into mobile phones at present
C.Users might take the mobile devices with them in near future
D.The new invention has alreay entered the healthcare market
25.The underlined word"detect"(Paragraph1)is closest in meaning toB.
A.protect  B.discover  C.settle  D.remove
26.What does the passage mainly want to tell readers?D
A.Dogs and cats have a strong sense of smell.
B.A new sensor is used to identify chemicals.
C.Modern technology is developing very fast.
D.Digital noses on a microchip can smell diseases.
17.Do you know of anyone who uses the truth to deceive (欺骗)?When someone tells you something that is true,but leaves out important information that should be included,he can give you a false picture.
 For example,some might say,"I just won a hundred dollars on the lottery (彩票).It was great.I took that dollar ticket back to the store and turned it in for one hundred dollars!"
This guy is a winner,right?Maybe,maybe not.We then discover that he bought  $200 worth of tickets,and only one was a winner.He's really a big loser!
He didn't say anything that was false,but he left out important information on purpose.That's called a half-truth.Half-truths are not technically lies,but they are just as dishonest.
Some politicians often use this trick.Let's say that during Governor Smith's last term,her state lost one million jobs and gained three million jobs.Then she seeks another term.One of her opponents says,"During Governor Smith's term,the state lost one million jobs!"That's true.However,an honest statement would have been,"During Governor Smith's term,the state had a net gain of two million jobs."
Advertisers will sometimes use half-truths.It's against the law to make false statements,so they try to mislead you with the truth.An advertisement might say,"Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache."It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too often.It's a sad fact of life:Lies are lies,and sometimes the truth can lie as well.
29.We may infer that the author believes people shouldC.
A.buy lottery tickets if possible          
B.make use of half-truths
C.be careful about what they are told      
D.not trust the Yucky Company
30.How many examples does the writer give to show how the truth is used to deceive?
C  
A.one             B.Two              C.Three             D.Four
31.Which of the following is true according to the passage?D
A.Using half truths is against the law.
B.Technically,half truths are in fact lies.
C.Yucky Pills is a very good medicine for toothache.
D.Governor Smith did a good job during her last term.
14.How Can I Fight Laziness?
Lazy people will never amount to anything in life.However,laziness can be defeated once a few changes have been made in your mind.
(36)AMany people lack sleep constantly,since they stay up too late and get up too early to prepare for work.These people have little motivation once they arrive home.Laziness works hand in hand with a lack of motivation and a tendency to put off things.By adjusting your sleep schedule to provide a few more hours of meaningful rest,you can fight laziness throughout the day.
Another way to fight laziness is to change your mind from passive to active.Some people treat their lives as if they were pushed from task to task.Others take a more proactive approach,viewing each task as a challenge they must overcome alone.(37)GSome people fight laziness by removing the temptations (诱惑) that surround them.A television in the living room may provide entertainment,but watching too much TV often contributes to laziness.(38)FComplete a few tasks and reward yourself with what you enjoy,such as a good dinner or a film.
Laziness can also be a lasting problem at home.Couples and children may all have different energy levels,but laziness can be spread if not dealt with immediately.(39)DBe the first to collect and wash dishes after a meal.Others in the home may eventually follow your example and perform their own task.It is difficult to practice laziness when you are surrounded by motivated people.
(40)CEnough exercise and a balanced diet can help you to develop a healthy lifestyle,thus enabling you to have more energy and help lift your spirits.

A.One way to fight laziness is to get enough sleep.
B.Knowing how to fight laziness is important.
C.Finally,taking exercise regularly can help you fight laziness.
D.To fight family laziness,set an example.
E.With strong determination,you will be able to achieve your goal.
F.Create a reward system for yourself,just as parents do for a child.
G.Laziness sets in when you no longer feel in charge of your own life.

"I'm four,"the child said proudly."I'll be four and a half."Harry turned to the mother."I remember your ticket,Madam,"he said."But you didn't get one for your daughter,did you?"
"Er,well…"the woman looked at the child."I mean…she hasn't started school yet.She's only four."
"A four-year-old child must have a ticket,Madam.A child's return ticket to Jersey costs…let me see…13.50.So if the railway pays for your hotel,you will owe 1.50.The law is the law,but since it's me who made the mistake…"
