When we talk about the number of days in a year，we are using “day” to mean 24 hours. But When we talk about day and night，we are using “day” to mean the time between sunrise and sunset. Since the _28_ looks like a ball，the sun can shine on only half of it at a time. Always one half of the earth is having day and the other have night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth. At the equator(赤道) day and night are always the same _29_. They are each 12 hours long. The sun rises at 6 oclock in the morning and sets at 6 oclock in the _30_ . For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the _31_ Hemisphere. Days are _32_ than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more _33_. Days are longer than nights. North of the equator nights are longer than days. _34_ is the season of long nights. _35_ is the season of long days. 28A. sun BearthCmoon Dstar29A. long BwideClength Dwidth30A. morning BafternoonCevening Dnoon31A.

Whale watching is a popular tourist activity in places where groups of killer whales live. Every day，dozens of boats filled with tourists go to watch the beautiful animals. Unfortunately，the engines of the boats make a lot of noise，and that may be causing problems for the whales，according to a report in the US science magazine Nature. The whales travel in groups，and communicate with each other through sonic(声波的) calls that some scientists refer to as singing. The sounds of the boat engines may be creating too much background noise for the whales to be able to hear each other. The researchers listened to recordings of whale calls made between 15 and 25 years ago，before whale watching became popular. These were compared to more recent recordings. They found that the animals have started to sing for longer than they used to，like a person shouting to a friend across a noisy room. It is believed that the whales are trying to communicate hunting or breeding information. Scientists said that，if this is prevented，the future of the worlds whale population could be in danger. “Animals become slow in mind and repeat themselves in noisy areas，” said Volker Deecke，a Canadian biologist. “They have to say things twice or three times in order to be understood. ”The killer whales studied were living off the coast of northwestern America. The number of killer whales in this area has been falling for several years，but scientists are not sure why. 36What does the underlined word “breeding” in Paragraph 6 mean？ASinging to other. BProducing young. CCaring about the old. DHunting for food. 37The passage mainly tells us _. Athe problems of whale watchingBhow killer whales communicate with each otherCthe reduced population of killer whales caused by whale watchingDhearing problems of the killer whales caused by whale watching38Now in a noisy background，the killer whales have to _. Asing in a louder voiceBsing longerCtravel in smaller groupsDget nearer to each other39Scientists believe that killer whales sing to _. Awarn each other of dangersBkeep in the same groupCsend useful informationDenjoy themselvesBWhy should mankind explore space？Why should money，time and effort be spent exploring and researching something with so few apparent benefits？Why should resources be spent on space rather than on conditions and people on Earth？These are questions that，understandably，are very often asked. Perhaps the best answer lies in our genetic makeup (基因构成) as human beings. What drove our ancestors to move from the trees into the plains，and on into all possible areas and environments？The wider the spread of a species，the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible. Nearly every successful civilization has explored，because by doing so，any dangers in surrounding areas can be identified and prepared for. Without knowledge，we may be completely destroyed by the danger. With knowledge，we can lessen its effects. Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them，they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spinoffs including improvements in earthquake prediction，in satellites for weather forecasting and in communication systems. Even nonstick pans and mirrored sunglasses are byproducts (副产品) of technological developments in the space industry！While many resources are spent on what seems a small return，the exploration of space allows creative，brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works，it also holds dangers. The danger exists，but knowledge can help human beings to survive. Without the ability to reach out across space，the chance to save ourselves might not exist. While Earth is the only planet known to support life，surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different，but human life and cultures have adapted in the past and surely could in the future. 40Why does the author mention the questions in Paragraph 1？ATo express his doubts. BTo compare different ideas. CTo introduce points for discussion. DTo describe the conditions on Earth. 41What is the reason for exploring space based on Paragraph 2？AHumans are natureborn to do so. BHumans have the tendency to fight. CHumans may find new sources of food. DHumans dont like to stay in the same place. 42The underlined word “spinoffs” in Paragraph 4 probably refers to _. Asurvival chances Bpotential resourcesCunexpected benefits Dphysical possessions43What makes it possible for humans to live on other planets？AOur genetic makeup. BResources on the earth. CThe adaptive ability of humans. DByproducts in space exploration. CFor many years，women could only be seen on the seat behind the men operating the twowheeled motorcycle. Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles. Since 1998 the number of female bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women to gather and ride motorcycles，so it started to organize events that help national health organizations and womens shelters. It also permits women to share a strong sisterhood，and gives financial awards to poor students. Like other motorcycle clubs，the members of Lady Sport Riders also help their community. Different from male riders，female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller，softer seats and controls that are easier to reach. Modern clothes for riding now look good and still provide protection. In the past，women rode motorcycles that traveled at a moderate speed. Now theirs are as powerful as the ones men ride. Safety is very important when riding because the risk of injury is high. So the women wear protective clothing and equipment at all times，especially for the head. Lady Sport Riders believes women have earned their place in the sport of motorcycle riding. When speaking of male motorcyclists，the members of the club say，“They Made the Game. We Came to Play！”44. What can we learn from the first paragraph？AMotorcycle riding used to be considered a male sport. BThe number of female motorcyclists is now larger than that of male riders. CFemale motorcyclists are more skilled at riding than male riders. DMore and more women have an adventurous spirit. 45In the beginning，Lady Sport Riders was organized to _. Aallow women to take up motorcyclingBoffer help to national health organizationsCshare their great interest in the sport of motorcyclingDsupply financial help to poor students46What do men motorcyclists mainly expect to get from motorcycling？AStrength and power. BA sense of freedom. CMoney and fame. DPleasure from this sport. 47Compared with the past，the present equipment makes riding more_ for women. Adifficult BpleasantCrisky DexpensiveDFrom the first use of the rocket to carry satellites into space，to the setting up of space stations，human beings have been putting great effort into space research. And so far，we have achieved many successes. But there are still numerous tasks in front of us and we should not cease trying to progress. The international space station is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word，if we want to explore space more，the first thing we should do is to set up a space station. As the space station costs a lot of money，it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone，and it has tried to do so，but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive，it is much cheaper than doing it alone. It is really a job that needs everyones effort and will benefit everyone. But even so，the funds needed are still a big problem. As for the USA，it seems that it has too many things to spend its money on. Although it is the richest country in the world，it has much debt every year. It has to make arrangements about its finance，and try to find a balance in all these issues. 48What is the authors attitude towards building and developing the international space station？ASupportive. BDoubtful. CCritical. DDissatisfied. 49From Paragraph 2 we can conclude that _. Athe necessity of building the international space station is not realized nowBmany experiments have been done in the international space stationCthe international space station is necessary for people to explore space moreDpeople have traveled to Mars from the international space station50Which of the followings is NOT a reason for countries cooperation in building the international space station？AThat it requires a lot of money. BThat it needs everyones effort. CThat it will benefit every participation country. DThat it is too far away from the earth. 51The underlined word “aggregated” in paragraph 3 can be replaced by “_”Aunited BscoldedCallowed DforbadeEFashion is moving into the twentyfirst century. A coat that changes colour with the weather，shirt stripes which disappear while you are wearing it，an odor (气味) free blouse that can be worn for days and days. . . These are not scifi fantasies，but the most recent developments in the fashion world，made possible by advances in fibre technology. Jackets by Stone Island change colour in warm weather and cost between $400 and $500. Peter Siddell，a store buyer says，“There isnt much more designers that can do with clothes. They need to make new fabrics to keep fashion interesting. ”Massino Osti is the man who has brought these unusual fabrics to the shops. Another Osti invention is the sweatshirt which has a logo on the chest which disappears when you breathe on it. Now there is a range of temperaturesensitive leisurewear for golfers who like to practise in all weathers. As golfers leave the warm clubhouse，their sweaters change from white to a rainbow of colours. Unika，a Japanese firm，has
