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5题**
He promoted the expansion of medical training to include genetics ____ supported the founding of genetics departments in North American medical schools.
A. nor
B. and
C. while
D. if
## 题目解析 ##
参考答案: B
答案解析:空格前为主谓语完整的句子,空格后又出现一谓语动词,即全句有一个主语,两个谓语。这两个谓语动词之间应用 and 连接,故选(B)。(A)用于否定句,(C)后接句子或现在分词短语,(D)接从句。
翻译:他推广促进了基因学纳入了医疗训练,并且对在北美医科学院中建立基因研究部门提供了大力支持。
## 解题思路
先看句子,空格前的内容有完整的主谓结构,为主谓宾结构,时态为一般过去时,空格后又出现了另外一个表示一般过去时的动词,故可判断 promoted 和 supported 共用一个主语 he。空格前后的内容是并列的,故空格处需要填入一个连接词来连接并列谓语,故选择 B 选项 and 最为合适。其余三个选项也都可作连词,nor 表示否定,while 可接句子或短语,但意思不符,if 后接从句,故排除这三个选项。
## 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 <u>for a year</u>.
② I'll wait for you <u>till 10 o'clock</u>.
③ I <u>was familiar with</u> nobody <u>at the meeting</u>.
④ Swimming <u>is good for your health</u>.
⑤ We can see <u>with our eyes</u> and write <u>with our hands</u>.
⑥ We succeeded <u>by cooperating</u> <u>with them</u>.
⑦ She seems to know the solution <u>to the problem</u>.
**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 <u>When he comes</u> I'll tell him about it.
② I wasn't long <u>before he told us about it</u>.
③ We <u>danced and danced</u> <u>until they all joined in</u>.
④ He was worried <u>because he hadn't had any letter from her</u>.
⑤ <u>Although everyone played well</u>, we lost the game.
⑥ We were <u>singing and dancing</u> all evening.
⑦ She has been learning English for six years, <u>but she doesn't speak it very well</u>.
⑧ The days were short, <u>for it was now December</u>.
