人教新目标英语：七年级上Unit7重点知识周周清
七年级上Unit7 基础知识周周清1
重点知识梳理：
1.______(短袜）______（鞋子）______（短裤）______（长裤）______（眼镜）等都是由不可分割的两个部分组成的一个物品，通常以_______形式出现。此类词作主语时，谓语动词用复数形式；但当它们与a pair of/pairs of (一双、一对或一副)连用作主语时，谓语动词谓语动词要根据量词pair的单复数来确定。
My shoes______（be) under the bed. That pair of shorts______(be) Jack’s. Those pairs of shoes______(be) Mary’s.
2. how much可用来询问_______________，其句型结构为“How much + be +主语?”，意为“……多少钱？”，其中be动词的形式由主语决定。回答该问句时，用It’s ...或They’re ...。询问物品的价格还可用句型“What’s the price of ...?”。使用这一句型时，不管所询问的物品是单数还是复数，be动词都用is，其答语用It’s ...。 How much______(be) the bread? How much______(be)the tomatoes What______(be) the price of the quilt? What______(be) the price of these bananas?
知识延伸：How much不仅可以价格，也可以询问数量的多少，后面直接不可数名词。例如：How much water do you need?你需要多少水。 3.基数词表达
1) one到twelve，拼写和读音无规律。
2) thirteen到nineteen，“十几”，在个位数后加后缀-teen，注意thirteen, fifteen和eighteen。
3) twenty到ninety，“几十”，以ty结尾，注意twenty, thirty, forty, fifty, eighty。 4) 21~29直到91~99，“几十几”, 用整十位数加个位表示, 中间用连字符“-” 把十位和个位连接起来。
5) one hundred “一百”，也可说 a hundred, 可加具体数字，如nine hundred (900)。此时, hundred要用单数。
2. 基数词用法：基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。如：
一名老师_______________ 两名男孩_______________ 17个学生_______________
二十个苹果_______________ 三十三个鸡蛋_______________ 49个杯子____________ 3. sale & sell
sale词性是_______, 含义为___________, 常用搭配： 减价销售___________= ________
待售__________
sell词性是______,含义为___________.其反义词是________.
__________________表示“把某物卖给某人或某地”__________________表示“以……价格销售某物” 一、选择题：
