新目标七年级上册Unit6Do you like bananas？讲解与练习
新目标七年级上册Unit6Do you like bananas?讲解和练习讲解1、必背短语French fries炸薯条，ice cream冰淇淋，countable noun 可数名词，uncountable noun不可数名词，running star赛跑明星，healthy food健康食品，lots of=a lot of 大量；许多，a list of food食物清单，eat well吃得好2、词语辨析have和eathave 既可以指“吃”，也可以指“喝”。
I want to have some milk and some apple.我想喝些牛奶，吃些苹果。
eat 通常作“吃”。
I eat an apple every day.我每天吃一个苹果。
3、句型讲解1）. —Do you like oranges? 你喜欢桔子吗？—Yes, I do. (P31) 是的，我喜欢。
like意为“喜欢”，“喜爱”。
like somebody or something 表示“喜欢某人或某事”。
如：I like him very much. 我非常喜欢他。
He doesn’t like salad. 他不喜欢沙拉。
2）. —Let’s have French fries. 我们吃炸薯条吧。
—Oh, no. I don’t like. (P32) 哦，不，我不喜欢。
动词have意为“吃”，“喝”，是实义动词。
如：We have breakfast at seven. 我们七点钟吃早饭。
I don’t have coffee in the evening. 晚上我不喝咖啡。
注意：have 作此义解时，变成疑问句和否定句时必须用助动词do。
试译：你每天在家吃中饭吗？误：Have you lunch at home every day?正：Do you have lunch at home every day?3）. Runner eats well! (P35) 赛跑选手吃得好！1)辨析：eat 或have：eat 与have 都可以表示“吃”的意思，有时两者可互换。

中考链接题
1．D 解析：由答语“I’m a little thirsty．”知第一个说话人是想喝点东西，在所给的
选项中，只有D项orange意为“橘子汁”，其余三项不合题意。故选D。
2．A 解析：句意为“我可以吃些东西吗？”“当然可以，给你些鸡肉吧。”some可接可数
名词、不可数名词，接可数名词时要用复数形式。orange作“橘子”的意心时为可数数
名词，可排除C。再根据其谓语动词is，要和单数、不可数名词主语搭配可排除B。
3．D 解析：句意为“所有的女教师在三月八日过得很愉快，因为这天是她们自己的节日。”
根据语境要用woman的复数women。
4．women teachers 解析：复合词的复数一般将该词尾变复数。但由man或woman构成的
复合词的每个词都要变复数。
5．B 解析：本题考查可数名词的复数形式。“吃树叶”中的“树叶”应为复数形式。以f，
fe结尾的可数数名词要将f，fe变为-ves。类似的还自knife，wife，life等。故选B。
