不定式作状语时,用来修饰动词、形容词、副词或整个句子,通常表示目的、结果、原因、程度等。
本模块主要学习不定式作目的状语的用法。
1.不定式和不定式短语作目的状语时,主要用来表示某一动作或状态的目的。
表示强调意义时,为了使目的意义更加清楚,还可以用短语in order to 或so as to表达,so as to还可以拆开写成so…as to, 但in order to不能拆开。
He ran fast so as to catch the first bus. = He ran so fast as to catch the first bus. 其否定形式分别为in order not to; so as not to如:I’ve written it down ________________________________________________(怕忘记). 2. 不定式或不定式短语表示的是主语的目的,因此,其逻辑主语通常是句子的主语。
判断正误:要正确画出地图,你需要一枝特殊的笔。
1) To draw maps properly, you need a special pen. ()2) To draw maps properly, a special pen is needed. ()3.由in order to 引导的目的状语,既可以置于句中,也可以置于句首,而由so as to 引导目的状语,能置于句中,而不能置于句首。
判断正误:他们出发得很早目的是及时赶到那里。
1) They started early in order to get there in time. ()2) In order to get there in time, they started early. ()3) They started early so as to get there in time. ()4) So as to get there in time, they started early. ()4. 不定式的复合结构作目的状语当句子的主语不是不定式或不定式短语的动作的执行者时,要用不定式的复合结构(即在不定式或不定式短语之前加for + 名词或宾格代词)作状语。
如:为了让这些孩子们进来,他打开了门。
He opened the door ________________________________________________________.5. 不定式作目的状语与目的状语从句的转换1) 当目的状语从句中的主语与主句中的主语相同时,可以直接简化为不定式或不定式短语作状语。
我们出发得早一点为了能准时到达那里。
We’ll start early in order that we may arr ive in time.→We’ll start early ___________________________________________________ in time.2) 当目的状语从句中的主语与主句中的主语不相同时,可简化成不定式复合结构作状语。
We are now using studying plans so that the students can learn English easily.→We are now using studying plans __________ the students __________ learn English easily.II. 结果状语从句1.结果状语从句通常由so …that或such …that 引导。
such是形容词,修饰名词或名词词组so是副词, 修饰形容词或副词。
该句型有以下几种结构:①so + 形容词或副词+ that从句②so + many / few + 可数名词复数+ that从句③so + much / little + 不可数名词+ that从句④so + 形容词+ a +可数名词+ that从句例如:so beautiful a flower such a beautiful flowerso many/ few workers such intelligent workersso much/ little water such rapid progressHe is so good a teacher that we respect him. (句型转化)→_______________________________________________________.Tom had _______ _______ _______ (如此少的钱)that he had to get a job.They are _______ _______ _______ (如此有趣的书) that we want to read them.2.so that 既可以引导结果状语从句也可以引导目的状语从句,(引导目的状语从句,从句中常有情态动词can, could, may, might, should等)I got up early so that I could catch the first bus.【当堂达标】I. 单项选择1. ____, you need to give all you have and try your best.A.
