There are no special celebrations for these birthdays,but each is a time when a person can do new things to mark their transition(转变)into adulthood(成人时期).After turning sixteen a person can work,get a driver's license and leave home.Many high school students learn to drive and get part-time jobs soon after celebrating their sixteenth birthday.At the age of eighteen a person in the United States can vote and smoke,but they are prohibited from going into many nightclubs,buying wine or gambling(赌博)until they are twenty-one.In many Latin(拉丁的)cultures,a young woman's fifteenth birthday is important.At this age,she is regarded as an adult. To mark this special day,families with teenage daughters have a celebration called a Quincentenary. The day begins with the young woman and her family going to church .Later, there is a party and many guests are invited.In Japan,young people become adults at twenty. At this age,they can legally(合法地)vote,drink wine and smoke. The second Monday in January is a national holiday called “Coming of Age Day”. On this day,twenty-year-olds celebrate by first going to a church to pray with their families. Later,they listen to speeches given by city and school leaders. Afterward,many celebrate with family or friends late into the night.In some countries,birthday celebrations continue through adulthood. Some people celebrate their fortieth and fiftieth birthdays,or their retirement(退休)years,with a huge party.( )1.In the United States,age sixteen marks the time when you can ________.A. vote and driveB. drive and get a jobC. drink wine and smokeD. go into nightclubs( )2.In some Latin cultures,the fifteenth birthday is important for ________.A. parentsB. young menC. both young women and young menD. young women( )3.In Japan, young people are considered as adults at age ________.A. sixteenB. eighteenC. twentyD. twenty-one( )4.Which of the following is NOT the turning point in a person's life in the United States?A.

Of course, the answer is “No” here in China.In America there is a school trying something new. At a high school in Florida,students will be able to choose their own classes. We all know that some students are better at some subjects than others. Some students plan to go on to college,while others will not. At this school students are able to find subjects they are interested in,and possibly even find the field (领域) they would like to go into after school. They are allowed to choose a subject like biology,math,a foreign language,or study skills like computer or car repair (修理).Some people think this is a good idea,because it helps students think about what they want to do in the future,and the school helps to give them the knowledge and skills needed to get there. They say that giving the students the chance to choose their own classes makes high school more interesting. Others disagree. They think that fourteen-year-old teenagers are too young to know what they will want to do in the future.What do you think? Would you like to be able to choose your own classes? Many useful changes have been made in education,but seeing the differences in each student is also important. How can we help each student become a better student?( )1.Students at a high school in Florida are allowed to ________.A. go on to college without taking big examsB. find a part-time job they would like to doC. learn how to make a computer or a carD. choose a subject that they are interested in( )2.Some people think allowing students to choose their own classes helps them ________.A. show how smart they areB. know differences between themC. prepare for their futureD. know their duties in life( )3.Some people don't agree students should choose their own classes because they think ________.A. some students are too nervous to make a right decisionB. some students shouldn't be a repair worker in the futureC. some students care little about their own futureD. some students aren't old enough to know what they want to do( )4.Which of the following is TRUE according to the passage?A. All the high schools in Florida give the students the chance to choose their own classes.B. Some people think allowing students to choose their classes can help them find their ownpossibilities.C. The school in Florida helps students by giving the knowledge and skills they will need.D. In the writer's opinion,it's not important to see the differences in each student in school education.

Others drink bottled water because it's easy—you can carry it around with you. In hot countries, like Greece, we often buy bottles of cold water in summer.However, making lots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source (资源) of energy. If we reduced the number of bottles we made, we would not need so much oil. Plastic bottles also pollute the environment. If we recycled all our plastic bottles, we wouldn't need so much space for rubbish dumps. But in Greece, we don't recycle much of the plastic we use. In 2023, Greeks recycled only about 10% of plastic waste. The rest became rubbish on land and in rivers and seas. So next time you want to throw away a plastic bottle in the littler bin, stop and think. If you recycled it, you would help the environment. But what can you do when there isn't a recycling bin near you Well, there are lots of useful ways in which you can use your bottles again. For example, youcan use an empty bottle to make a great piggy bank for your pocket money, and if you cut a bottle in half, you will have a plant pot. Go green! You can make a difference.(1) What is not mentioned about bottled water in this passageA.It's healthy. B.It's clean.C.It's easy. D.It's expensive.(2) Plastic products are made from _____.A.energy B.oil C.rubbish D.plants(3) _____ of plastic waste became rubbish in Greece in 2023.A.10% B.50% C.80% D.90%(4) Which is the best way to deal with used plastic bottlesA.To recycle them. B.To make a piggy bank.C.To make a plant pot. D.To drop them into rivers.(5) The underlined part in this passage tells us "_____".A.To make a different life, you'd better go outsideB.To look different, you'd better wear green clothesC.To protect the environment, you can do somethingD.To go green, you should use plastic products阅读下列短文,根据短文内容,从短文后各题所给的选项中,选择最佳选项。
