五年级上册暑假自学课（译林版三起） Unit 7 Shopping smart 语法易错+巩固练习 语法易错01 语法01：how much的用法 how much表示“多少”,其后加不可数名词，其用法如下： 1. how much用于询问价格,可单独使用, 意为“多少钱”。 (1)当主语为单数时： 例:—How much is this pen?这支钢笔多少钱? —It's five yuan.它是5元。 (2)当主语为复数时： 例:—How much are these bananas?这些香蕉多少钱? —They're twenty yuan.它们是二十元。 ★注意: How much 后的 be 动词需要和其后的名词保持一致。 2. how much用于询问不可数名词的量。 ★注意: how many 和 how much 均用于提问数量，但是二者运用情况不同，how many 用于提问可数名词的数量，而how much用于提问不可数名词的量。 例:(1) —How much cheese do you have?你有多少奶酪? —I have two kilos of cheese.我有两公斤奶酪。 (2) —How many books do you have?你有多少本书? —I have three books.我有三本书。 知识演练01 一、从方框中选择合适的内容填空，填序号。 A. are B. much C.
