高三英语复习笔记 Unit 2 Grade 1
Language tiphave been to… 意思是“到过…地方”。如：I have been to London many times. / Have you ever been there before? 你以前去过那个地方吗？对比have gone to… 意思是“已到…去了”，如：He has gone to the chemistry lab.
first of all，第一，首先。如：First of all I must check the number. 首先我必须检查那号码。注意：at first 解释“开始、起初”：At first he was very shy in school.
allow是“让，允许”的意思: It is not allowed by law. 法律不允许。由allow组成的句型有: allow sb. to do sth.允许某人做某事；allow doing sth. 允许做某事；allow sb. sth. 允许某人某事。如：My parents won't allow me to stay out late. 我的父母不允许我深夜还不回家。We don't allow smoking in public. 我们不允许在公共场所吸烟。 He allows his son too much money. 他给他儿子太多的钱。
once用作连词，相当于from the moment that, when，意思是一旦，一……就……，引导时间（条件）状语从句。注意：once引导的从句不能用将来时，而用一般现在时，例如：Once you see the film, you will never forget it. 一旦你看了这部电影，你将永远不会忘记。once 作副词，解释“从前;曾经”: He once lived in Paris. 又：She went out shopping once a week.（一周一次）
follow one's instruction 按照某人教导。类似结构还有 follow one’s order、follow one’s advice等。follow 还有“跟随”、“沿着”、“听懂”之意：I followed him out. / Follow this road until you get to the cinema. / Do you follow what I’m saying?
unless = if… not，意思是“除非…，否则…”，但语气要重一些。注意：在unless引导的从句里，动词用一般现在时，不用一般将来时。如: I'll be back tomorrow unless there's a heavy snow. = I'll be back tomorrow if there isn't a heavy snow. 除非下大雪，否则我明天就回来。Don't touch anything unless your teacher tells you to. 从句中to是不定式符号，后面省略了动词touch，以避免不必要的重复。作为不定式的符号，to一般是不能省略的。例如：My parents wish me to study medicine in the future, but I don't want to. 我的父母希望我将来学医，但我不想。
what about…是用来征求对方意见的用语。它的后面可以跟名词、代词、动名词、副词，还可以跟状语从句，可以用来询问消息、提出建议或征求意见。如：What about a cup of coffee? 来杯咖啡怎么样？(征询意见)What about his family? 他的家庭情况怎么样？(询问消息) What about going to France this summer? 夏天到法国去怎么样？(提出建议)#P#
make sure 表示“确定、查明、确保”。后面常接宾语从句或of短语，但通常不接不定式。如：Make sure (that) you get enough sleep. 你一定要有足够的睡眠。We've made sure of our seats for the movie. 我们已经订好电影院的座位了。接不定式用be sure：Be sure to bring a dictionary with you tomorrow.
a way of sth./doing sth. 表示 “（做）某事的方式或方法”，如：He had a good way of working out the problem. 他用一种好办法解出了这道题。I don't like his way of living. 我不喜欢他的生活方式。
make + sb./sth. + adj. 结构中，make 的意思是“使…，致使…”，后面形容词作宾语补足语，用来修饰人或事物的性质或所处的状态，所以 make one's classes lively and interesting意思就是“使某人的课生动有趣”。如: The smell of cooking makes me hungry. 烧菜的味道让我感到肚子饿。 make＋名词＋do，表示“让某人做某事”，如: The teacher made her copy the whole text. 老师让她抄写整篇课文。注意：考试中经常会考到的是这个结构的被动语态，此结构变为被动语态时，不定式结构要带to，那么上一句话就变为：She was made to copy the whole text.
fill 意思是“填满，装满”，后面常接介词 with，表示“用……装满”，如：Fill the hole with sand.也可以用于被动结构中be filled with…, 即“被……装满”。如：She was filled with happiness when she heard the news. 她听到这个消息的时候，心中充满了欣喜。另外还有一个词组是be full of, 也表示“装满了……”。如：The bottle is full of milk. 瓶子里装满了牛奶。
mix 混合，搅拌。后面常接介词with。例如：Oil and water don't mix. (= Oil doesn't mix with water.) mix up 意为“混淆，搞混”，例如：I'm afraid I have mixed your names up. mix的名词形式是mixture，意为“混合物”，例如：Air is a mixture of gases.
dip 的意思是“蘸，浸”，后面常接介词in/into，例如：I dipped my pen in the ink. 下面一句话是什么意思？ I haven’t read that book properly; I’ve only dipped into it.
You must do everything as I do. 由as引导的从句是方式状语从句。有一句非常有名的西方谚语: When at Rome do as the Romans do. 入乡随俗，这句话直译应该是：在罗马时，就要像罗马人那样行事。as作“如，像，按照”解。as也可以引导时间状语从句，意思是“当…的时候，随着…”，例如：As time passed, I nearly forgot the thing. 随着时间的流逝，我几乎忘了这件事。as还可以引导原因状语从句，意思是“因为，由于”，例如：As he had no car, he couldn't get there early. 因为他没有车，所以不能早到那儿。
taste 意思是“品尝”，它可以作及物动词，如：She tasted the soup to see if she had put enough salt in it. 她尝了尝汤，想知道是否放够了盐。taste 在The mixture tasted terrible.句中作系动词，意思是“尝起来”，后接形容词作表语。类似的系动词还有smell, look, sound, feel等等，因为它们都是表示感觉的动词，又叫感官动词。如：He tasted the medicine and found it tasted bad. taste 还可作名词：This fruit has a terrible taste.
instead of 后面跟名词、动名词、代词、形容词或介词短语等等，意思是“代替”，“而不是”。如：I stayed in bed all day instead of going to school. ／ He likes pop songs, instead of classical music. 他喜欢流行歌曲，而不喜欢古典音乐。He went there on foot instead of by bus. 注意：instead 是副词，一般用于句末，后面不再跟其他词，用于否定前面提到的东西，如： Yesterday I didn’t go there on foot. I took a bus instead.
