Most of their work is done with the students. But the staff sees a lot of parents, too.“Parents meetings make clear monthly diagram( 图表) ,” says Mildred Foreman, head of the Guidance. "The diagram stays much the same from year to year. The busy months are October, March and May."September, the beginning of a new school year, starts rather slowly. Few parents come in.

April is also the second busiest month for the staff.D. The parents help to do most of the work.（C）In our life, we don’t often expressed our gratitude(感激) to the one who’d lived those years with us. In fact, we don’t have to wait for anniversaries to thank the ones closet to us--- the ones so easily overlooked(忽视). If I have learned anything about giving thanks, it is time to give it now! While your feeling of appreciation is alive and sincere, act on it. Saying thanks is suchan easy way to add to the world’s happiness.Saying thanks not only brighte ns someone else’ world, it brightens yours. If you’re feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need, Of course, there are times when you can’t express gratitude immediately. In that case don’t let embarrassment sink you into silence--- speak up the first time you have the chance.Once a young minister, Mark Brian, was sent to a remote parish of Kwakiutl Indians in British Columbia. The Indians, he had been told, did not have a word for thanking you. But the Brian soon found these people had exceptional generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks.I wonder if we had no words in our vocabulary for thanking you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive, more caring?39. What is the main idea of this passage?A Thanks for everything. B. Caring others. C. Expressing yourself. D. Helping each other.40. What is the purpose of the writer in writing this passage?A. Praise thanks.B. Solve problems in life.C. Thank everyone.D. Let the reader know the importance of expressing thanks in life.41. Why does the writer give the example in the 4th paragraph?A. It indicates (显示，指出) the Indians did not thank you.B. It indicates the Indians didn’t know to thank you.C. It indicates that thanking you exists everywhere.D. It indicates that Mark Brian got thanks.42 What does the underlined word “left out” in the second paragraph mean?A. go to another placeB. be ignoredC. give out CD. leave for四、根据上下文提示完成单词（共4分，每小题1分）1.

Increasingly, that’s no longer the case.Chinese people born before 1985 generally think that foreign brands are better than Chinese ones, billionaire William Li told Business Insider during a recent interview on CCTV 9. But for who were born after 1985, it is a different picture.“When I first went to the United Kingdom in 1997, I thought that th e difference between China and Europe was quite big,” Li said. “But for those born in the 1990s, when they visit Europe or the US, they do not think there is a big difference.”The change in thinking among Chinese buyers is showing up in many markets in Chinawhere western companies used to control. A study by Credit Suisse published in March found that young Chinese buyers are increasingly showing a home brand bias.”More than 90% of young Chinese buyers would prefer to buy home appliance brands, according to the study. Meanwhile, home companies producing food, drinks, or personal care products increased their share of the market by 3, 3% over the last ten years to nearly 70%.“Chinese buyers, especially the younger ones, don’t just believe that foreign br ands are better. Right now, Chinese buyers think China is good and ‘Made in China’ is not bad at all,” Charlie Chen, head of China buyer research at Credit Suisse, told South China Morning Post in March.The Chinese smartphone market is controlled by home companies—Huawei, Oppo, Vivo, and Xiaomi. Apple is the only foreign brand in the top five, but it has lost large ground to the home brands in recent years. Its market share is believed to be down to 37% from a 2015 high of 54%.31．What is this passage mainly about?A．The quality of ‘ Made in China’.B．The change in Chinese buyers’ thinking.C．Chinese products in the eye of foreigner.D．Difference between older and younger Chinese buyers.32．Which of the following is true according to the text?A．More and more foreigners go to buy Chinese products.B．Foreign products are more expensive than Chinese ones.C．More and more Chinese buyers prefer Chinese products.D．Older Chinese people don’t like foreign products any more.33．Which fact best explains “home brand bias”?A．Apple had a market share of 54% in 2015.B．More than 90% of young Chinese buyers prefer home brands.C．Chinese people born before 1985 think that foreign brands are better.D．William Li found a big difference between China and Europe in 1997.34．Who did most of the research for this report?A．Credit Suisse. B．CCTV 9.C．South China Morning Post. D．Business Insider.35．What’s the best title for this passage?A．Chinese products get more popular at homeB．Young Chinese are crazy for foreign brandsC．‘Made in China’ is welcomed all over the worldD．Apple has lost large ground to Huawei in ChinaLanguage students often think they have memory problems. They worry because they can’t remember words. In fact, the problem usually isn’t with thei r memory. The problem is with how they study.To remember words better, you need to understand how memory works. There are two kinds of memory: short-term and long-term. When you see, hear, or read something, it goes first into short-term memory. But short-term memory lasts for only a few seconds. You will only remember something longer if it goes into long-term memory. Your long-term memory is like a very big library with many, many books. And like a library, it’s organized（有条理的）.When you put away a book-or memory-you can’t just leave it anywhere. You have to choose a place where you can find it again.How can you do this with vocabulary? The answer is to work with the word and think about the word in new ways. You can do this by writing new sentences that include it. Even better, you can invent a little story about the word, with people or places that you know. Another way is to make a picture in your mind with the word. For example, if the word is height, you can think of the tallest person you know and try to guess his or her height. All of these activities are good ways to think about words. They make the meaning of words stronger in your long-term memory. And they give a way to find a word when you need it.36．the writer’s opinion, students can’t remembe r words because ______.A．they have memory problemsB．they’re too worriedC．they don’t use a proper wayD．they don’t like to study37．Which is TRUE about memory according to the passage?A．Short-term memory is seldom used.B．What we see goes into long-term memory first.C．We will forget a word soon if it goes into short-term memory.D．We will never forget a word if it goes into long-term memory.38．The underlined part in Paragraph 2 means long-term memory ______.A．keeps many books like a large libraryB．works like a well-organized libraryC．provides any book you wantD．leaves memory anywhere39．Which is one example of ”thinking about the word in new ways” in Paragraph 3? A．Making sentences with the word.B．Listening to some familiar stories.C．Talking with people that you know.D．Drawing pictures of the word on paper.40．This passage mainly tells us about _____.A．language students’ problems in studyB．how to make the meaning of words strongerC．short-term and long-term memoryD．how to improve ways to remember words四、信息匹配配对阅读左栏是对中国传统文化感兴趣的五位外国学生的描述，右栏是中国传统文化活动的简介，请为左栏的每位学生选择一个合适的活动。

One day he became very ill, andeverybody thought he would die. They sent for a doctor in town, who arrived twodays later and examined the sick (生病的) man. The doctor asked for a pen and some paper to write down thename of the medicine. But there was no pen or paper in the village, because noone could read or write.The doctorpicked up a piece of burnt wood (木炭) from fire. Using the wood, he wrote the name of the medicine onthe door of the house. “Get this medicine for him,” he said, “and he will soonget better.”Marek’s familyand friends did not know what to do. They could not read the strange writing.Then the village baker (面包师) had an idea. He took off the door of the house, put it on his cart (大车) and droveto the nearest town. He bought the medicine, and Marek was soon well again. Hewould not let anyone wash the magic (有魔力的) words from the door.()1.

It was about 2,000years ago that the Chinese first made paper. China still has pieces of paperwhich was made as long as that. However, Chinese paper was not made from thewood of trees but made from the hair-like parts of certain (某些) plants. It was a German named Schaeffer who found out that people could make the best paper from trees. Whenwe think of paper, we think of newspapers, books letters, envelopes (信封) and writing paper. But there aremany other uses. Paper is very good for keeping you warm. You can wear paperboots in the snow. Nothing could be warmer. The latest use in paper seems to bepaper houses. These are not small houses for children to play in, but real bighouses for people to live in. Now people have made paper boats. But they havenot yet made paper plants or cars. Just wait—they probably (或许) will.()6. Chinese paper was once made from ________.A. woodB. trees in the forestC. grassD. hair-likeparts of plants()7.
