自我评析：
这节课上所要学生听懂、会说、会读和会拼写单词apples, oranges, bananas, peaches, grapes, pears, some，kilo. 听懂、会说、会读、会写句型how many kilos?...kilos, please. 能听得懂、会说和会读日常交际用语i'd like some...,please．here you are. 其中单词部分就只有grapes和 kilo是新单词，其余的单词在三年级中都已学过。对于单词的拼写基本没什么问题，主要是这些水果的复数的读音有一些问题，虽然我已在课上总结了规律，但是仍然有一些学生会发生错误。学生对于老师上课设的圈套没什么防备心理，一下子就钻进去了，最好的证明就是我在提问一公斤怎么说之后，又问两公斤怎么说，大部分学生想都不想就回答：two kilo! 显然是错误的。这节课所学的水果的复数形式同样可以套用在kilo这个词上面。
