It is said that the car has made the United States a nation on wheels. And it helped to make the United States what it is today.There are three main reasons why the car became so popular in the Unites States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation.The second reason is that the United States never really developed an efficient and cheap form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Today there is a good system of air service by plane. But air travel costs too much money so that it cannot be used frequently.The third reason is the most important one. The American spirit of independence is what had really made cars popular. Americans don’t like to wait for a bus, or a train or even a plane. They don’t like to have to follow an exact timetable. Ther efore the freedom a car gives them is what Americans want most.The decrease of oil supplies has caused a big problem for Americans. But the fear will not be bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much oil.51. That the United States is called a nation on the wheel is because .A. cars are very popular in AmericaB. there are many wheels in AmericaC. there are many planes in AmericaD. there are many trains in America52. The most important reason why cars are so popular in the US is .A. Americans like to visit different placesB. Americans like to go about freelyC. the American spirit of independenceD. other types of transportation are not so efficient53. According to the sentence “ And it helped to make the United States what it is today”(Line 2,Para1), we can conclude that .A. the car has made the United States a very rich countryB. the transportation has been developed rapidlyC. the car has become America’s most modern form of transportationD. the car has made it possible for Americans to enjoy their modern life54. All of the following statements are true except .A. the American people are quite mobileB. air service plays an equally important part as the car doesC. people have been trying to find the solution to the short supplies of oilD. Americans’ independent spirit plays a role in the popularity of cars55. The word “efficient” in the third par agraph probably means .A. inexpensiveB. economicalC. convenientD.speedyCOn my first day of high school, I asked an eleventh-grader where my class was. And he told me it was "on the fourth floor, next to the pool." I found out five minutes later that we didn't even have a fourth floor and there was no pool either! Besides that, I didn't have any trouble with the older kid.I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music and other activities at school makes it easier to get to know people in every grade.The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I've prepared for the night before, gotten an A, but not remember anything later. I've changed that this year, and I enjoy school so much more. Don't take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!While drinking and smoking might be present in some middle schools, they are also around in high school. I have a lot of friends who promised they would never drink or smoke, but are now partying every weekend. If you have "fun" and spend your nights wasted instead of studying, you will regret it when you are applying for (申请) college. The "friends" who say you are a loser for not partying are really not your friends at all. It's hard to see your closest friends grow apart and go in different directions, but don't follow their footsteps. Follow your own path in life and make your own decisions.56What happened to the writer on his first day of high school?A. He had a fight with an eleventh-grader.B. He was fooled by a schoolboy.C. He was five minutes late for class.D. He fell into a pool on the fourth floor.57According to paragraph 2, the writer thinks that in high school _____.A. It needs hard work to finish homeworkB. There are very few activitiesC. It's hard to meet new people thereD. There is always much free time58The writer advises high school students to _____.A. give up sportsB. choose useful classesC. try their best to get good gradesD. get ready for test the night before59.The passage is probably written for ______.A. high school studentsB. high school teachersC. college studentsD. sports players60.The last paragraph mainly tells us ______.A. about the trouble caused by drinking and smokingB. about the importance of making friendsC. not to go to any party in high schoolD. not to lose ourselves in high schoolDSteven woke on Christmas morning to find a new sled (雪橇). "Oh, wow!" he shouted. This was the best Christmas present! Steven was still excited as the rest of his family opened their gifts. Secretly, he hoped he could get outside quickly to try out his new sled.Finally, Steven asked, "Dad, is it okay if I try out my sled?" Dad agreed. Soon, Steven was sledding down Twin Hills in the neighbourhood park. He felt the wind against his face as he flew down.Later that day, Steven carefully leaned (靠) the sled up against the outside of his house under his bedroom window.The next day, Steven ran outside as soon as he could. "Oh, no!" Steven shouted. His sled was missing! He ran as fast as he could to the park. There at Twin Hills he found it! Steven's neighbour, Kevin, was on Steven's new sled! "Kevin! That's my sled! You stole my new sled!" But Kevin just laughed and headed up the hill for another run down.Steven ran home, crying all the way. He found his dad in the garage (车库) and told him what had happened. Steven's dad said, "Calm down, Son. There may be another reason for the missing of your sled."Steven couldn't believe his dad was siding with Kevin. "But, Dad. Kevin's at Twin Hills using my sled right now! We need to go to get it!"Dad said patiently, "First of all, you need to make sure your sled is actually stolen. Look over there." Steven was surprised at what he saw. His sled leaned against the wall of the garage next to his bicycle. Dad put his arm around Steven and said, "I put your sled away last night when I saw you had left it outside." Steven hung his head. He felt bad about the way he had spoken to his neighbour. "I should say sorry to Kevin," he said. Dad replied, "There's no time like the present."61．What did Steven do after Dad agreed?A．He opened all his presents. B．He received the most presents.C．He tried out his new sled. D．He went back to school.62．Where did Steven see Kevin on the second day?A．Under his bedroom window.

A．Because Kevin took it away. B．Because Steven's dad put it away. C．Because Steve's dad lost it. D．Because Kevin lent it to others. 65．How did Steven feel after hearing his dad's words?A．Confident. B．Satisfied. C．Excited. D．Regretful.EThe deer (鹿) is the king of the woods. The deer is one of the largest woodland animals, but it is so shy that you might find it hard to really spot one. During the day, deer hide in the high grass quietly, listening for any noise and ready to run away at the first sign of danger. Nighttime is when deer really get active. They move around all the time in search of grass and other plants to eat. They can run as far as 60 km in one night! Female (雌性的) deer live in groups with their young, while males (雄鹿) prefer to be on their own or with other males.But in the autumn, things change. The woods are full of the sounds of male deer. They let out sounds to draw females’ attention and to let other males know that they are ready to fight over the female deer. Male deer fight each other with their antlers (鹿角).A baby deer is called a fawn (幼鹿). The coat of a newborn fawn is covered in pretty white spots (斑点) that disappear as it gets older. The mother deer watches over her babies and bravely protects them from dangers. Although female deer don't have antlers, they fight off other animals by kicking!A male deer's antlers carry on growing all his life. A ten-year-old deer's antlers can have more than 10 branches (分枝) and weigh 20 kg each. Every spring, the antlers drop off and an even larger set will take their place. You can tell how old a deer is by counting the number of branches on his antlers. The more branches it has, the older the deer is.66．In Paragraph 1, the word "spot" has the closest meaning to "________".A．make B．hurt C．raise D．see67．What do the deer do at night?A．Look for food.
