You’ll find that you’re expected to keep closer track of your own schedule and responsibilities with fewer people checking up on you. At the same time, your classes are likely to become more challenging, and youmight be participating in new school activities as well.Some students find it hard to keep up with everything at first, which is totally normal. One way to prepare in advance for these higher expectations is to make sure that you have organized schedules in place before you start high school.Another important skill for meeting these higher expectations is building a strong support network. No matter how strong a student you are, at some point you will need some help. Keeping healthy relationships with your friends and teachers is a great way to make sure that you have people who are willing to help when you need them, Try to get to know at least some of your teachers beyond your classroom communication. Be an active learner during class and stay after class to ask questions. Take advantage of email or class messaging systems. The better your teachers know you, the better prepared they’ll be to help when you need them.It’s important for you to keep in mind as you start high school that no one is perfect. Transitions are hard for everyone, and starting high school is a big transition. These challenges provide a great chance to reinvent (重塑) yourself.27. In the author’s view, the biggest difference between high school and middle school is ______.A. different relationshipsB. the higher pressureC. high academic (学术的) achievementD. the higher expectations28. Which of the following suggestion is not mentioned in the text?A. Careful schedules.B. Healthy relationships.C. Reviewing notes.D. Using network information.29. Who is the article written for?A. Students in junior school.B. Teachers in high school.C. Parents of high school students.D. Students in senior high school.30. What is the best title for the text?A. How to Get Through the Transition of Freshman Year of High SchoolB. How to Become an Active Learner in High SchoolC. What to Prepare to Keep up with Everything in High SchoolD. How to Meet Your Teacher’s High ExpectationsIII.完形填空(每题1分,共15分)When I was young, I often went to my grandfather’s farm and helped with the farm work.

AWhat is the most important day of your life? For many people the answer is your Wedding Day—the day when you marry another person and promise to live together as husband and wife for the rest of your lives.Wedding celebrations differ from country to country—in China the bride wears red while in India the wedding continues for three days. However, in Britain the bride wears white and wedding usually only lasts for one day.In the UK it is possible to get married in a religious or civil ceremony. A religiousceremony takes place in a church. A civil ceremony, on the other hand, can be held in an office, in a hotel, or even on a boat.On the day of the wedding the bride and groom are kept separate until the ceremony. It is said to be bad luck if the groom sees the bride in her dress before the wedding. The bride arrives at the ceremony accompanied by her father and bridesmaids. They officially give her away to her new husband. During the ceremony the happy couple exchange vows and give each other wedding rings which they will wear forever. At the end of the ceremony they kiss.Afterwards they go outside where friends and family throw rice or color papers over them and then they go on to the reception where there is a lot of food and drink. After the meal the father of the bride and the best man make speeches. Then the bride and groom take the first dance. It is a lot of fun. Finally, at the end of the party the newly-weds leave to go on honeymoon, usually to a very romantic destination.21.What function is the first two paragraphs?A .To tell us that we have most important day in our life.B.

It’s time to enjoy yourselves!There are many ways to celebrate this special month of graduation. You can have photos taken with your classmates and teachers, or dine out together and exchange gifts.High school students in western countries such as the United States and Canada usually have a party to mark their graduation. It is to mark the time when kids turn into young men and women. After the party, teenagers either go to college or find a job. It means they will no longer depend on their parents as before.At the party, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.Common party activities include dining, dancing, crowning of a ball king and queen, and just talking to friends. In some cases, high school students collect funds for their class party through the four years of their high school.High schools in or near large cities may rent big rooms at expensive hotels or, to be unusual, on a pleasure boat. But often costs are cut by simply using the school gym. Students make a lot of efforts to decorate the gym to make the event special. The music played at the party will be the most popular kinds, like rock and hip-hop.Sometimes teachers and parents also go to the party. But others like to go with friends,to whom they are soon going to say good-bye.If you like the idea of a party, why don’t you and your classmates organize one for your graduation?25.The writer’s purpose in writing this passage is to ________.A. tell an interesting experience of high school studentsB. tell how the western students spend the last days of high schoolC. tell how western high school students usually celebrate graduationD.introduce several ways of the western students’ killing time26.What does the party mean for western high school students that are about to graduate?A.

Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate (分离) the bacteria before they can even start to develop a way of transferring it to cattle and sheep.Another group of scientists, meanwhile, have suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians are believed to eat the national symbol already.It’s low in fat, it ’s got high protein levels and it is very clean in the sense that basically it is free-range(放养的) animal,”said Peter Ampt of the University of New South Wales’ institute of environmental studies.29.

The golden red sun was setting. She was on the beach, looking up at the fiery ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.The atmosphere relaxed her. This was what she needed.“It is getting late.”she thought,“I must go home. My parents will be wondering where I am.”She wondered how her parents would react, when she got home after the three days she was missing. She kept on walking, and the road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.It was really getting dark now. The sun had set a few minutes before and it was getting cold, too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... Itall seemed deserted. She couldn’t understand what was going on.She entered the house. First she went into the kitchen where she saw a note written by her father. It said:“Dear Ellen, there is some coffee ready. I went looking.” Ellen was her mother, but where was she? On the right side of the hallway was her parents’room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she had not slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different...she wasn’t in her mother’s room and she was not wearing the old clothes she ran away in. She was in her cozy bed in her pajamas. It felt so good being back home. Suddenly she heard a voice,” Are you feeling better now, dear? You know you got us very, very scared.”33.Three days later Jennifer came back home _________.A. at sunsetB. at sunriseC.at nightD.at midday34.Her father didn’t take care of the garden because ________.A. he had to look after his wifeB. he was busy looking for herC. he was not strict with his jobD. he no longer enjoyed working in the garden35.What can we infer from the passage?A.
