名词性从句和状语从句.pptVIP

* 2、有时-where构成的复合词也可引导地点状语从句 如： ①Everywhere they went, they were warmly welcomed. ②We’ll go anywhere the Party needs us. 2、地点状语从句 3、where 引导状语从句和定语从句的区别: where 引导状语从句时,前面无名词或代词， where也不能换成 介词+which where 引导定语从句时, 前面有先行词， where 可以换成 介词+which 试比较下面两个例句： Make marks where you have any question . （状语从句） Go back to the place where you were born. （定语从句 ） (where = in which) 常用引导词：because, since, as (语气由强到弱) 特殊引导词：considering that(考虑到）, now (that) ，seeing (that)因为，鉴于 ①My friend was fat because he dislikes doing exercise. ②Now (that) everybody has come, let’s begin our meeting. ③Considering that he is 70 years old, he has done a good job. 三、原因状语从句 because, since, as, for 用法比较： ㈠、because: 语气最强 ①回答why问句时用because,但是表示因果关系时，不能与so连用。 ②用来引导表语从句 He didn’t speak to you. It was because he didn’t recognize you. ③用在对原因状语强调的强调句中 It was because he was ill that he was absent from the meeting. ㈡、since: 译为“既然…” 表对方已知的事实或理由，常放在句首。 Since you have got a good chance now, you had better make full use of it. ㈢、as: 译为“由于…”语气较弱，较口语化，表明显的原因或已知的事实，常放在句首。 As he had been ready for the worst, he was not disappointed at the result. ㈣、for：连接两个并列分句，不能放在句首。 It must have rained last night, for the ground is wet. 四、结果状语从句 常用引导词： so that, so… that, such … that, 如： ②It was very cold, so that the river froze. ①He always studied so hard that he made great progress. ③It’s such nice weather that all of us want to go to the park. 注意比较：so 和 such的用法(1)such 是形容词，修饰名词或名词词组，且such 后既可以加可数名词也可以加不可数名词。 如： such a nice flower/ such nice flowers such rapid progress　　　  　 (2)so是副词,只能修饰形容词或副词。如： so young /so fast (3) so 还可与表示数量的形容词many, few, much, little （少）连用，形成固定搭配。如： so many people /so few flowers so little money It was such a hot day that we couldn’t sleep. → It was so hot a day that we couldn’t sleep. （4） such + a/an + adj.+ 可数n单数 =so + adj. +a /an+可数n单数 ① If you ask
