In the zoo I can see tigers, elephants, monkeys, pandas, bears, dolphins, giraffes and many other animals. Some animals are very friendly, but some are not. Tigers, bears and some snakes are very dangerous. That is why they have to stay in cages. But I don’t think it’s good for animals to stay i n cages. They should be free(自由). The animals in cages can’t be happy. Tigers usually live in forests and mountains. They can run very fast. They catch and eat small animals like rabbits and deer, but now they live in small rooms. They have nothing to do every day. So they walk in the cages, and they want to get out. When they are tired, they sleep. I feel sorry for them.
I think the most interesting animal in the zoo is the dolphin. I like watching them swim and jump. They swim fast and they jump very high. They can play with a ball. They can stand up and“walk”on water! They are very friendly to people. If you fall into the water and can’t swim, they may come up to help you.

课时作业(二) 1．在△ABC中，a＝2b cos C，则这个三角形一定是() A．等腰三角形B．直角三角形 C．等腰直角三角形D．等腰或直角三角形 答案 A 2．已知△ABC中，AB＝3，AC＝1，且B＝30°，则△ABC的面积等于() A. 3 2 B. 3 4 C. 3 2或 3 D. 3 4或 3 2 答案 D 3．在△ABC中，a＝15，b＝10，A＝60°，则cos B＝() A．－22 3 B. 22 3 C．－ 6 3 D. 6 3 答案 D 解析依题意得0° 解析 由正弦定理a sin A ＝b sin B ，得1sin A ＝3 sin B . 又∵B ＝2A ，∴1sin A ＝3sin2A ＝3 2sin A cos A . ∴cos A ＝3 2，∴∠A ＝30°，∴∠B ＝60°，∠C ＝90°. ∴c ＝12＋(3)2＝2. 5．(2013·陕西)设△ABC 的内角A ，B ，C 所对的边分别为a ，b ，c ，若b cos C ＋c cos B ＝a sin A ，则△ABC 的形状为( ) A ．锐角三角形 B ．直角三角形 C ．钝角三角形 D ．不确定 答案 B 解析 ∵b cos C ＋c cos B ＝a sin A ，由正弦定理，得sin B cos C ＋sin C cos B ＝sin 2A ，∴sin(B ＋C )＝sin 2A ，即sin A ＝sin 2A . 又∵sin A >0，∴sin A ＝1，∴A ＝π 2，故△ABC 为直角三角形． 6．在△ABC 中，角A 、B 、C 所对的边分别为a 、b 、c ，已知A ＝60°，a ＝3，b ＝1，则c 等于( ) A ．1 B ．2 C.3－1 D. 3 答案 B 7．已知△ABC 的面积为3 2，且b ＝2，c ＝3，则( ) A ．A ＝30° B ．A ＝60° C ．A ＝30°或150° D ．A ＝60°或120° 答案 D 8．已知三角形面积为1 4，外接圆面积为π，则这个三角形的三边 课时作业(三十二) Unit 2 Robots Ⅰ.用所给词的适当形式填空 1.The superstar showed up at the court，________(accompany) by his manager. 2.The young lady dressed________(elegant) when she went to work. 3.He was right in his________(assess) and wrong in his prediction. 4.He is an________child.He always________his parents and never________rules in school or laws in society.(obey) 5.Everyone knows she is a________girl who has a________for singing.(talent) 6.It________in his________that the country was in a messy________.(state) 7.To the________of the boss，his products could________the need of the customers.(satisfy) 8.The old blind man asked me to do him a________and find his________book.(favour) 9.It is reported that the lost boy________(not find)so far. 10.Having a trip abroad is certainly good for the old couple，but it remains________(see) whether they will enjoy it. 答案：1.accompanied 2.elegantly 3.assessment 4.obedient；obeys; disobeys 5.talented; talent 6.was stated; statement; state 7.satisfaction; satisfy 8.favour；favourite 9.hasn't been found 10.to be seen Ⅱ.完成句子 1.John__________________(极其渴望)to become a writer of the science fiction. 2.__________________(据宣布)the new library which is under construction would be opened to the public next year. 3.His father isn't__________________(支持)his thought while his mother always__________________(陪他去书店)． 4.Do your parents often__________________(打电话)to ask your recent progress？ 5.__________________(且不说费用多少)，do we actually need a second car？ 6.Owing to his hard work，his classmates all think John__________________(注定会成功)． 7.I'm about to__________________(转身)and see who he is but my phone rings. 8.Her only fear was that her little son would______________(让……一个人留下)in the world in case something happened to her. 课时作业13 Unit 5 Music Ⅰ.短语填空 be familiar with, in cash, Sorting out , break up, or so, above all, break up, are honest with, rely on, play jokes on, In addition 1．All the goods here must be paid for ________ instead of by credit. 2．—What is his new work? —________the newspaper by the year. 3．It's time for us to ________ our party.It is nearly midnight. 4．If you ________ others，they will be glad to help you when you are in trouble. 5．Everyone thinks that your mother is a reliable person to ________. 6．There were 30 students ________ attending the lecture by Professor Green. 7．My elder brother is fair，hard-working and ________ honest. 8．It's not polite to ________ the disabled；they may get annoyed. 9．________，there are another six applicants from your school. 10．What you should do at present is to ________ the new environment.
