The boy brought me lots of happiness when I was in the lowest spirits.One day, the boy put his teddy bear on my bed and asked, “Would you help me take care of the bear, please? Could you help me keep it till I get better?” Before I could answer, he had been take n away by his mother.I had thought that the boy just had a serious cold, but I was sad when I was told that he had cancer (癌症) and had to start his last period (时期) of treatment. I felt sorry for him and lucky for myself.A little boy could be so confident of getting better. Why couldn’t I do that?The boy didn’t come to my room anymore, but I would never forget what he gave to me that day. It was much more than a teddy bear.

How the Sick Boy Gave Me New Hope（B）We usually send and receive information through the movement of our bodies. For example, when someone is giving a lecture, he or she may often use his or her hands to emphasize (强调) points or to point out something on the blackboard.The victory (胜利) sign, the OK sign, the good-b ye wave, and the blowing of a kiss are all popular gestures in theUnited States. However, most of these gestures are not accepted by people in other countries. For example, the OK gesture means acceptance in the United States, but it has other meanings in other countries. In France, it means worthlessness (无价值), while in Greece it is a sign of quite disrespect.There are also some differences between men and women in the non-verbal(非语言的) messages. In American, men usually sit or stand with their legs apart and hands outward, while women usually keep their legs together and their hands at their sides. Women are more likely to sit quietly than men. Women are also better than men at expressing themselves using gestures.In short, body language is simple and useful, so we should learn how to use it in our everyday lives. ( )16. Which gestures are mentioned in this passage?① the stop sign ② the OK sign ③ the good-bye wave ④ the quiet sign⑤ the victory sign⑥ the kiss signA. ①②③⑤B. ②③⑤⑥C. ①③⑤⑥D. ②③④⑤ ( )17.

Greek (C) One of Beijing’s largest parks, Purple Bamb oo Park has five bridges and three lakes. Here you can find locals and tourists exercising, walking about, fishing and chatting among the trees, meandering (弯弯曲曲的) streams a nd interesting pools. T he park was built in 1953. It is a nice free public park, and visitors can enjoy themselves there till 9 p.m. Purple Bamboo Park was once home to the Temple of Longevity (Wanshou Temple), where the Qing rulers could have a rest during their journey from the Forbidden City to the Summer Palace. The temple site is a powerful spot with great views of the park. You can take a boat tour from Purple Bamboo Park along the Royal Canal all the way to the Summer Palace, just like the Qing Emperors. Though the views along this boat ride are limited (有限的), the Summer Palace is quite a way outside of the center of town, and going by boat is certainly more enjoyable than sitting in a taxi on the crowded roads. Therefore, arriving just inside the gate of the Summer Palace beside the famous Jade Belt Bridge really does make you feel like an emperor, and makes for a wonderful start to your Summer Palace tour.

(D) All pet owners know that pets use their body language to communicate with us. Cats do this with their ears, bodies and sounds. Sometimes they simply want our attention, while other times, they are telling us: “my food bowl is empty”. Pet owners can soon understand these and then satisfy their pets’ needs. The more you show your understanding of what your pets are telling you, the better they will be able to communicate with you. New research shows that 62% of people believe that their pets understand them when they speak to them. At least 18% say that their pets understand them completely. 67% think that they understand what their pet wants or needs. The researchers also studied other things, for example, how pet owners communicate with their pets, and how the relationship (关系) between the owners and their pets is. Many families have more than one pet. 74% of pet owners have a dog, while 46% have a cat, according to the research. Although 15% of all owners said they had cut the expense of their pets in the past year, 48% of dog owners and 28% of cat owners said that they still spent much money buying their pets gifts last Christmas.
