3. environmental protection 环境保护10. avoid doing sth 避免做某事1. be made of 由……制(构)成,后接构成某物质的原料。This skirt is made of silk.(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。The kite is made of paper.(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。The paper is made from wood.Butter is made from milk. (3)be made up of 用……构成或组成的,指人、物皆可,指结构成分。Our class is made up of six groups. 2. It seems that many people all over the world drink Chinese tea.句型“It seems that…”意为“看起来好像/似乎……”,It seems that he was late for the train. (1)seem to do sth此句型可与“It seems that…”转换。They seem to find the way to the cinema. =It seems that they find the way to the cinema.My temperature seems (to be) all right. That seems not a bad idea. 3. When the leaves are ready, they are picked by hand and then are sent for processing in factory.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。When the fruit are ready, they are picked and are sent to the market for sale.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。No matter what I said to her, she still didn’t believe me.The police are trying to find out where the boy got off the train.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。①find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。② look for意为“寻找”,是有目的地找,强调“寻找”这一动作。I’m looking for my pen everywhere. He is looking for his shoes. 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。Please find out when the train leaves. Read this passage,and find out the answer to this question.1. 时态:在英语语言中,时态主要讨论行为动词发生的时间。He often helps me with my English. (help这个动作经常发生often;故用一般现在时)2. 语态:在英语语言中,语态主要讨论句子主语与行为动词的关系。语态有两种:主动语态和被动语态。The tall boy often hits his classmates .汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,Chinese is spoken by the most people in the world.(主语Chinese是谓语动词speak的承受者)3. 语态与时态的关系:在任何一个英语句子中都同时存在语态和时态,他们是分析一个英语句子的两个主要元素。① He is looking after his sister at home. ② He is being looked after well by his parents. 二. 被动语态最基本的句型结构:be +及物动词过去分词② 被动语态中的谓语动词必须是及物动词;因为被动句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可用于被动语态。1. 当不知道或没有必要指出动作的执行者时,常用被动语态,这时往往不用by 短语。Mr. White, the cup with mixture was broken after class. (只是告诉老师杯子坏了,不知是谁弄坏的,或不想说出谁弄坏的)。2. 突出或强调动作的承受者,如果需要说出动作的执行者,用by 短语。The cup was broken by Paul.四. 主动语态变被动语态的变法:主动语态与被动语态之间如何转换2. 把主动语态的谓语变成被动语态的be + 过去分词,时态要与原句保持一致。3. 把主动语态的主语变为介词by的宾语,放在被动语态里谓语动词之后,by 短语可以省略。如果原句主语是地点名词,在被动语态中用in + 地点名词作状语。五. 一般现在时的被动语态:am /is/ are +doneTea is grown in Hangzhou.
