每日语法：IB英语语法练习（五）

　　语法可以说是学习语言的基础，但它又是非常机械枯燥的东西，从而导致它在我们IB考试备考中最容易被忽视。今天我们就继续学习英语语法练习，一起看看吧。

　　1.Relaxation, _______ fresh air, pure water and clean food, is essential to a soundmind and healthy body.

　　A. much less than

　　B. no less than

　　C. no more than

　　D. any less than

　　B no less than “与……同样(重要)”。全句意为: “放松休息, 就像新鲜空气、纯净水、清洁的食品一样, 是健康的身心所不可缺少的。”

　　2. It is far better to do well a bit of work which is well _______ a large fortune.

　　A. worthy to be done than have

　　B. worth doing than to have

　　C. worthwhile to do than have

　　D. worthy of doing than have

　　B to have a large fortune与to do well a bit of work…是并列不定式。另外，worth, worthy, worthwhile在用法上的区别是:(1)worth是介词, 后接动名词或名词，形成介词短语。接动名词时, 与主语是动宾关系，其形式是主动的，意义是被动的。如: The book is worth reading. (2)worthy是形容词, 置于be动词后或名词后面, 做后位修饰语, 其结构是: be worthy of doing sth., sth. is worthy to be done。(3)worthwhile是形容词，要与形式主语it并用：It is worthwhile to read the book.worth和worthy都不能用于这种结构。

　　3. Understanding the cultural habit of another nation, especially_______ containing as many different subcultures as the United States, is a complex task.

　　A.one B. the one  C. that  D. such

　　A one 指代前面提到的具有泛指含义的可数名词单数, 在该句中指代another nation, 句中属于泛指，可见B是错误的。such指代前面讲过的整个情况，多用作主语。that 指物时常用来指代不可数名词, 指代可数名词时具有特指含义。

　　4. Whether or not the next plan will yield any positive results _______ to be seen.

　　A.remain  B. remains

　　C.is remained D. have remained

　　B whether 引导名词性从句做主语, 谓语动词应为单数。另外，remain一般不用被动式, 所以B为正确选项。

　　5. If ever again_______ happens an accident like this, we will have only ourselves to blame.

　　A. it  B. so  C. there  D. that

　　C 这是there be句型的异化形式，即there be 句型中还可以用be以外的不及物动词，如live, stand, exist, come, remain等。
