Get the children!” John shouted at her, “Tell us where the children are!” “In the 42 ,” answered the woman loudly, “down the hall and to the left.”Though Mary disagreed, John 43 into the bathroom that was full of smoke and terribly hot. He found the door and two children. As he left, he could hear some more crying. He passed the two badly scared children onto waiting arms and 44 how many more children were down there. They told him 45 more and Mary caught his arm and cried, “John! Don’t go back! It’s dangerous! That house will fall down any second.”But he ran into the smoke-filled hallway and at last he found both children. As he climbed up the stairs, the thought went 46 his mind that there was something strange about the little bodies next to 47 , and at last when they came out into the 48 and fresh air, he found that he had just 49 his own children.The baby-sitter (保姆) working for John and Mary had left their children at Fred Jones’ home50 she was doing some shopping.36.A. dog B. father C. friend D. children.37.A. light B. smoke C. water D. rubbish38.

Xiushui StreetD. the Summer Palace54. The passage is most likely to be taken from .A. a travel guideB. an instructionC. a newspaperD. an advertisementBThese days shared bikes are becoming the center of attention in my WeChat friend circle. Many of my friends are sharing photos of themselves riding bikes, especially during the weekend in natural parks, and I can see people logging in (登录) and out of shared bike apps.I’m very happy that there are shared bikes on the road. They have saved us a lot of time during special situations, and on beautiful, clear days, people enjoy riding them outside the city.I tried shared bikes last week, and I didn’t like them very much. I think the first shared bikes without baskets are designed for athletes. They are very hard to ride, and the seats are not comfortable. It makes me wonder whether people really like riding shared bikes or are just saying this to agree with others.A friend secretly told me she tried the bikes to fit in. She doesn’t like bikes and finds Beijing’s roads too hard for bike riding. But recently, the only way to hang out with her friends is riding out of town together. To join in social activities, she had to pick up bike riding again.Another friend admitted that he started talking about and sharing photos on shared bikes in order just to appear modern and fashionable to friends. He started paying attention when shared bikes first came into use.These views will give me something new to think about when I ride these bikes again.55. What does the writer himself think of shared bikes?A. They are very difficult to ride.B. Their seats are comfortable.C. Athletes like shared bikes.D. They can save us a lot of money.56. The underlined word “admitted” may mean _______________ in the passage.A. told a lieB. told the truthC. kept a promiseD. kept a secret57 Which of the following is NOT true according to the passage?A. It’s quite simple to use shared bikes at special time.B. Some people only appear to be interested in shared bikes.C. The writer likes the bikes without baskets because they are for athletes.D. Some people like to share photos riding bikes because they want to agree with others.CWhen you cough or sneeze, you’d better turn your head away from others and coveryour mouth with the full part of your hand. And then, you should say, “Excuse me.”This seems so simple, but it is surprising how many kids have never been told to do this.Actually, I notice adults all the time who cough and sneeze in public without placing a handover the mouth. One important thing I point out to the kids is that after they sneeze or coughon their hands, they should wash their hands as soon as possible. If not, they will be passing those germs (细菌) along to everything and everyone they touch.If you come to a door and someone is following you, hold the door. If the door opensby pulling, pull it open, stand to the side, and allow the other person to pass through first,then you can walk through. If the door opens by pushing, hold the door after you passthrough.After a few weeks of seeing kids try to get through doors in the school and watchingthem enter restaurants as the door hit other people, I knew I had to discuss the problem withmy students. Teaching them small acts of kindness, such as letting someone else go through a door first as theyhold it open, may seem unimportant, but it can go along way toward helping students realize how to be polite and thank others. Once they’ve been told, they’re halfway there.When we have to go up moving stairs, we will stand to the right. That will give otherswho are in a hurry a choice of walking up the left-hand side of the moving stairs. Whenwe are going to enter a lift, the underground, or a doorway, we will wait for others to exitbefore we enter.After college when I moved to London, I was surprised at how polite everyone was in the subways. I was even more touched when I traveled to Japan. In both places, people madeefforts to make way for others. On moving stairs, everyone stood to the right and walked to the left. On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter.58. When you cough or sneeze, you should ________.A. touch everythingB. cover your mouthC. point out to the kidsD. pass the germs to others59. If you come to a door and someone is following you, you’d better _______.A. hold the doorB. pass throughC. close the doorD. stand to the side60. Why should we stand to the right of moving stairs?A. Becaus e it’s dangerous to stand to the left.B. Because it’s a traffic rule which we must follow.C. Because we must wait for others to move first.D. Because we should make way for people in a hurry.61. From the passage we can know the writer is a ________.A. doctorB. travelerC. parentD. teacher62. A. The passage is mainly about ______.A. the rules of acts in publicB. the ways of communicationC. the problems of meeting peopleD. the knowledge of social lifeDMany people think that keeping a diary is something that teenage girls do. It’s seen as a place to write down secrets, things you don’t want anyone else to know. The stereotype (模式化观念) is that only women keep diaries. In fact, keeping a diary is a very old tradition. It can be useful for many different types of people. Many famous people have kept diaries. Many powerful people have kept diaries. Some of these people include famous writers and presidents.Keeping a diary is said to have health advantages. Studies show that keeping a diary, that is, writing out thoughts daily, can reduce asthma symptoms (哮喘症状).Writing uses your left brain, which is thoughtful and organized. While your left brain is busy, your right brain is free to create and feel. This allows you to use all of your brain power to better understand yourself, others, and the world around you.The key to successful diary keeping is not stopping any thoughts from coming through. This even means allowing thoughts that influence you to come out in your writing. It helps make your feelings clearer, and is especially useful if a person is faced with a hard decision. Sometimes just writing down the ideas you agree and disagree helps you better understand a problem. You begin to see a problem from different ways. This is helpful if you don’t agree with others.63. What does the word “it” in Paragraph 4 mean?A. Keeping away from illness.B. Using your right brain to create.C. Stopping some thoughts coming through.D. Allowing thoughts to come out in your diary.64. According to the passage, keeping diaries can help ______.A. get along with othersB. understand things betterC. know more about the old traditionD. become famous in the future65. What is the main idea of the passage?A. The advantages of keeping diaries.B. Keeping a diary with your left brain.C. The ways of keeping a diary successfully.D. The reasons girls like keeping diaries.第II卷（60分）四. 词汇运用（共10小题；每小题1分，计10分）根据句子意思，用括号中所给汉语提示或英文单词的适当形式填空（每空一词）66. The project he devoted much time to ________ (success) at last.67.
