【重点语法】
反意疑问句
反义疑问句遵循这样一个原则,前肯定后否定,前否定后肯定。
1. 肯定陈述句+否定提问 如:Lily is a student, isn't she?
2. 否定陈述句+肯定提问 如:She doesn't come from China, does she?
3. 提问部分用代词而不用名词 如:Lily is a student, isn't she?
4. 陈述句中含有否定意义的词 如:little, few, never, nothing, hardly等,其反意疑问句用肯定式(对于第四点大家不要忽视,尤其是列举的这几个词,出题的时候经常遇到,对于下面的两个例子大家要仔细看一下,要把这个知识点彻底搞懂)。
如:He knows little English, does he? 他一点也不懂英语,不是吗?
They hardly understood it, did they? 他们几乎不明白,不是吗?
5. 反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时,陈述部分要视为肯定含义,问句部分用否定形式。如:Your father is unhappy, isn't he?
The man is dishonest, isn't he?
It is impossible to learn English without remembering more words, isn't it?
Unit5 What are the shirts made of?

【考点详解】
1. made of 由……制(构)成,后接构成某物质的原料。
例:This skirt is made of silk.这件裙子是用丝绸制成的。
be made of/from/up of的区别
(1)be made of 表示制成成品后,仍可看出原材料是什么,保留原材料的质和形状,制作过程仅发生物理变化。
例:The kite is made of paper.风筝是用纸做的。
(2)be made from 表示制成的东西完全失去了原材料的外形或特征,或原材料在制作过程中发生化学变化,在成品中已无法辨认。
例:The paper is made from wood.纸是木头做的。
Butter is made from milk. 黄油是从牛奶中提炼出来的。
(3)be made up of 用……构成或组成的,指人、物皆可,指结构成分。
例:Our class is made up of six groups. 我们班是由六个小组组成的。
2. It seems that many people all over the world drink Chinese tea.
好像全世界的许多人都在喝中国茶。
句型“It seems that…”意为“看起来好像/似乎……”,其中seem是连系动词,意为“似乎;好像”,句型中的it是形式主语,不能用其他代词来替代。
例:It seems that he was late for the train. 看来他没赶上火车。
seem的几种常见结构:
(1)seem to do sth此句型可与“It seems that…”转换。
例:They seem to find the way to the cinema. =It seems that they find the way to the cinema.
他们似乎找到了去电影院的路了。
(2)seem+形容词
例:My temperature seems (to be) all right. 我的体温看上去正常了。
(3)seem+名词
例: That seems not a bad idea. 看上去主意不错。
3. When the leaves are ready, they are picked by hand and then are sent for processing in factory.
当茶叶成熟时,就被用手工采摘然后送到工厂加工。
此句是由when 引导的时间状语从句,are picked, are sent都是一般现在时的被动结构。
例:When the fruit are ready, they are picked and are sent to the market for sale.
当这些水果成熟后就被摘下来并送到市场上卖掉。
4. No matter what you may buy, you might think those products were made in those countries.
无论你买什么,你都可能认为那些产品是在那些国家生产的。
此句为由"no matter +特殊疑问词"引导让步状语从句。意为“无论….”,相当于whatever。
例:No matter what I said to her, she still didn’t believe me.
无论我对她说什么,她仍然不相信我。
5. find out, 查出,找到。
例:The police are trying to find out where the boy got off the train.
警察正在查找这个男孩是从哪下的火车。
find,find out和look for都含有“寻找、找到”的意思,但其含义和用法却不同。
① find意为“找到、发现”,通常指找到或发现具体的东西,强调的是找的结果。
Will you find mea pen? 你替我找支钢笔好吗?
② look for意为“寻找”,是有目的地找,强调“寻找”这一动作。
例:I’m looking for my pen everywhere. 我正到处找我的钢笔。
He is looking for his shoes. 他在找他的鞋子。
③ find out意为“找出、发现、查明”,多指通过调查、寻问、打听、研究之后“搞清楚、弄明白”,通常含有“经过困难曲折”的含义,指找出较难找到的、无形的、抽象的东西。
例:Please find out when the train leaves. 请查一下火车什么时候离站。
