【历年真题】托福语法真题训练50 (附答案)小马过河为大家准备了“【历年真题】托福语法真题训练50 (附答案)”，供各位备考托福的考生们参考使用，来提高自己的托福成绩！免费咨询电话：400-0123-2672001年01月语法题1・ A three-foot octopus can crawl through a hole ----------- in diameter.(A)than one inch less(B)less than one inch(C)one less inch than(D)than less one inch答案：B分析：这是一个简单句，空格是hole后的定语，答案是Bmore than , less than是习惯用法,表示多于,少于的意思。

(A)(0 (D)语序混乱，很容易排除。

参考译文：一只3米长的章鱼可以钻过一个直径不小于1英的孔。

2.----- a dopted the decimal system of coinage in 1867・(A)Canada(B)When Canada(C)Canada, which(D)There was Canada答案:A分析：这是一个简单句.空格是作句子主语.答案是A.单个名词做句子主语。

相关类型的题H可参照“黄金规则一”來解题(偶老师教的)：一个句子有且只有一个谓语，如果有了一个谓语，就不能再有一个谓语了，如果非要有另外一个谓语，则必须同时有连词、关系代词、关系副词。

反Z,如果一个句子里面冇关系代词、关系副词、那么这个句子冇2个谓语，每増加一个关系代词/副词，则要增加-个谓语。

可以拥此思路判断BCD为错。

(B)多了when，而后乂没冇从句的谓语；(C)如果用T which,则Canada后没有了谓语;(D)如果是D,那么Canada后面应该是adopting表示主动。

参考译文：加拿大于1867年在货币上采用了十进制。

3.Generally, the representatives -------- a legislature arc constitutionally elected by abroad spectrum of the population.(A)who they compose(B)who compose(C)and compose(D)compose答案：B分析：这是一个主从句。

主语representatives后已经有了谓语are constitutionally elected,所以其后的空格应该是个从句。

答案B ,定语从句。

(A)从句冇个多余的主语they :(C)and前(名词representatives)}v\(动词compose)成分不对等，构不成平行结构，and也不能引导定语从句；(D)无从旬引导词，2个谓语，错。

参见本单元第2题的题解。

参考译文：通常，组成立法机关的代表是由各个阶层的人民群众通过宪法选举出來的。

4.The Actor' s Studio, a professional actors' workshop in New York City, provides where actors can work together without the pressure of commercial production.(A)a place and(B) a place(C)so that a place(D) a place is答案：B分析：这是一个主从句。

空格在主语的及物动词后面，H然是做宾语。

答案B•单个名词做句子宾语。

(A)and是并列连词，后面应该是做平行结构。
