Unit 18　Look after your things!

【重点、难点点拨】

　1．学习归纳人称代词（主格，宾格）。

主格	I	you	she	he	it	we	you	they
宾格	me	you	her	him	it	us	you	them

　　人称代词的主格在句中作主语。
例如：
　I am a worker.　　　我是工人。　
　She is a teacher.　　她是老师。
　　人称代词的宾格在句中作宾语。换言之，动词或介词后面的宾语如果是名词就可直接用。如果是人称代词就一定要用它的宾格形式。
例如：
　I want a kite.　我想要个风筝。（宾语是名词，直接用。）
　Can you take him to the hospital?　你能带他去医院吗？（宾语是代词，须用宾格形式。）
2．I think so.　我认为是这样。
　当我们用yes作答语时，语气是相当肯定的。而I think so.　是强调而又不很主观的语气。
例如：
　　Can you mend the bike?　你会修理自行车吗？
　I think so.　　　　　　我想我会修。
　否定句式是：I don't think so.　我认为不是这样。

【重点、难点例题解析】

1．选择填空。
　　(1)I have two bags.　One is red, _____ is green.
　　　A. other　B. the other　C. others
解析:
　　　other可以当形容词用，意思是“其他的”。
例如：
　　What other things can you see?　你还能看见其他什么东西吗？other还可以作代词与the连用。the other 表示特指两者中的另一个，常常以“one… the other”(一个……另一个……)的结构使用。而others表示泛指别人或其他东西。
例如：
　　Do good to others.　对别人做好事。
　　Some say this, others say that.　有的说这个，有的说那个。
本题答案是B项。
　　(2)What's _____ your bike?　It's broken.
　　A. this about
　　　B. that about
　　C. wrong about
　　　D. wrong with　
解析:
　　What's wrong?　表示询问别人出了什么事了。还可以说What's wrong with…?介词with
后面可以跟人或物（名词或代词）。
例如：
　　What's wrong with the plane(it)?　这飞机（它）出了什么毛病了？
　　What's wrong with Tom (him)?　　　汤姆（他）怎么了？
　　本题答案是D项。
