摘要：基础的语法知识对于备考雅思考试至关重要，如果语法知识不够扎实很可能就会造成我们读不懂文章，写不出正确的句子，说不出准确的英文。本文将从雅思语法基础训练入手，帮助同学们深入地了解相关的语法概念。下面我们就来看一个关于介词和连词的语法题目。

## 语法题目 ## **介词和连词第10题** ____ plants, which manufacture their own food, animals obtain nourishment by acquiring and ingesting their food. A. Unlike B. Different C. Whereas D. As much ## 题目解析 ## 参考答案: A 答案解析：两个逗号之间是非限定性定语从句，接着是主句，空格后是一个名词，空格处显然缺介词构成介词短语作状语。四个选项中只有(A)是介词，故选(A)。(B)、(D)都不能构成状语，(C)引导从句，不能选择。翻译：与能够自己制造食物的植物不同，动物则通过进食和消化摄入来获得各种营养物质。 ## 解题思路先看句子，第一个逗号后为定语从句，第二个逗号后为主句，这两个句子主谓结构完整，故逗号前的内容是作状语的。空格后是一个名词，故空格处需要填入介词或介词短语，与 plants 一起作状语，四个选项中只有 A 选项为介词，且代入空格后，符合句意，故为正确答案。 ## 知识点梳理 ## **介词** 介词是英语词类中的一种虚词，不能独立在句中充当句子成分。但介词与其宾语一起构成介词短语以后，就可以在句中充当多种句子成分，可以作主语、补足语、定语和状语等。介词的作用：介词是把名词与动词、形容词或另外的名词连接起来，以表示前后词语之间的关系。常见介词：at, by, for, from, in, near, of, off, on, during, since, before, after, until; inside, out of, within, without, outside, throughout; as to, until after, except for; at the cost of, at the mercy of, by means of, in place of, by favor of, in spite of, in/with reference to, in/with regard with ① I have lived here for a year. ② I'll wait for you till 10 o'clock. ③ I was familiar with nobody at the meeting. ④ Swimming is good for your health. ⑤ We can see with our eyes and write with our hands. ⑥ We succeeded by cooperating with them. ⑦ She seems to know the solution to the problem. **连词** 连词是英语词类中的一种虚词，不能独立在句中充当句子成分，但可以起连接作用，即连接词与词或句与句。连词有两类：从属连词和并列连词。从属连词都引导从句，比如状语从句、定语从句等；并列连词可以连接两个互不依从的词、短语或分句。常见从属连词：when, while, as, before, after, until, till, since, if, unless, so that, because, although 等常见并列连词：and, or, but, yet, for, either…or, both…and, not only…but also, as well as, neither…nor 等 ① When he comes I'll tell him about it. ② I wasn't long before he told us about it. ③ We danced and danced until they all joined in. ④ He was worried because he hadn't had any letter from her. ⑤ Although everyone played well, we lost the game. ⑥ We were singing and dancing all evening. ⑦ She has been learning English for six years, but she doesn't speak it very well. ⑧ The days were short, for it was now December.

以上就是这道语法题的详细解析和知识梳理。同学们在备考雅思的过程中，在学习基础语法知识的同时，也可以找一些相关语法题目进行相应的雅思语法基础训练，来巩固所学习的语法知识。
