4.Can animals be made to work for us? Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings. 　　They point out that at a circus, for example, we may see elephants, monkeys, dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely, you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them. 　　Of course, as we know, dogs can be used to guard a house, and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia, for example, pigeons which are birds with good eyesight, are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others, it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour. 　　Apes have been used in America in helping to make cars, and scientists believe that these large monkeys may be one day gather crops and even drive trains.[单选题] Many animals may be trained to do simple jobs if they know __.

7.Passage ThreeMost students choose “Homestay” accommodation when they study abroad：others select Homestay even if they are not on a study visit．Statistics show that it’s a form of accommodation gaining in popularity all the time．But what is Homestay? And what makes it so popular?Homestay means living with a family，or“host family”as we say．There are three ways of doing it：choose to learn English in a language school near to your Homestay location：have your English classes in the house with a member of the family who is a qualified teacher；select not to have classes at all when you visit——a popular choice if you want to do the tourist thing for example．Even in their busy summer period the organizations that arrange the Homestays will always try to place you with the most suitable host family to match your requirements．Placement(安置)organizations think about location，interests，language level，eating requirements，allergies (过敏)and other requests you may have．Though prices vary according to your needs，good quality Homestay accommodation can be relatively economical--and although you may be charged an extra amount of money if you want your Homestay in or near the city center．Even if you stay further out，you can expect your journey into the center not to exceed 30 minutes.Not only does Homestay accommodation represent value for money， it also gives you an excellent opportunity to practice English with your host family．This is a very important extra for students who like to speak as much English as possible． But if you plan to learn English，why not have your English classes in your host family． There’s no better way to learn English than this—the perfect combination of learning and accommodation combined with the cultural experience !Homestay is an ideal choice for students who __________ .

8.A wind tunnel is used for testing planes or plane models.In a wind tunnel air is blown over a plane ora model placed in a test section.Wind tunnel test sections are different in size depending on airflow speed requirements.Some low-speed tunnels have test sections large enough for a complete small plane.In the very high speed tunnels used for space testing，however，the model may be as small as a pencil.There are two ways of feeding air to the test section.In the constant flow tunnel，airflow produced by electric fans is forced through the tunnel to the test section，then through another tunnel section back to the starting point for reuse.The other way involves storing high-pressure air in a box，sending it out by a controlling device to pass through the tunnel and test section into another box.This way is usually used for a very short period of high-speed airflow.Wind tunnels are usually used to test planes before they are flown.Problems in a plane carl be found when it meets the high-speed airflow in the tunnel.For example，if the wings are built so that they would weaken at high speeds，this fact can be discovered in the tunnel，thus saving many lives and millions of dollars.In a wind tunnel，scientists also find out how different planes will act at different speeds.They find out such things as how the air dives by the wing surfaces，how slowly a plane can fly before it starts to drop，and howfastit can climb.What can we learn from the passage?

11.Train companies in Tokyo are taking action to reduce the number of people jumping in front of trains．They are fitting blue lights on station platforms to try and create a more calming atmosphere．The East Japan Railway Company has invested almost $170,000 to install the lights in all of the 29 stations on the capital's busy Yamanote Line．There has been an alarming rise in the number of people committing suicide at train stations．A total of 68 people threw themselves under trains in the year up to March．This compares with 42 suicides in the same period a year earlier．In 2008, Japan had nearly 2,000 suicides by jumping in front of a train; around six percent of all suicides nationwide．Suicides have risen sharply in the past decade due to poor economic conditions. 　　No one knows if the blue lights will work．There is no evidence to show that blue light reduces suicidal feelings． Keihan Railway spokesman Osamu Okawa stated: "We thought we had to do something to save lives．We know there is no scientific proof that blue lights deter suicides, but if blue has a soothing effect on the mind, we want to try it to save lives." The Associated Press news agency reports on a Japanese therapist called Mizuki 　　　Takahashi．She explained her reasons why the blue lights might be a good idea: "We associate the color with the sky and the sea．It has a calming effect on agitated people, or people obsessed with one particular thing, which in this case is committing suicide," she said．Other companies are watching this experiment with interest.[单选题] The use of blue lights to reduce suicides __.
