delta语法

loralu

语法部分：delta-2-1: Because older adults have poorer vision and hearing,
_______ some things they do not perceive as well as they used to.

A. along with B.thus C.there are D.but also

用排除法选了C，但是有个问题，things后面是不是省略了that? 这种省略在托福考试中常见吗？

delta-2-17: It is (highly) recommended that any person (exploring) a cave（carries） a



source of (artificial) light.

答案是C， 说是要改成carry, 可是any person不是单数吗？

delta-2-23： （The） North American branch of the family Mustelidae, （whose）



members vary greatly in （appearance） and habits, （consists） otters,



weasels, skunks, and badgers.

答案是D， 没问题。 但是C应该用复数吧，不是and连接平行结构吗？是不是只要是consist没有加of的选项必错呢？

delta-2-25 The largest poisonous snake, the king cobra, can be twice as long _______.

A. than the tall polar bear     B.as the polar bear is tall

C.is taller than the polar bear     D.the polar bear is not as tall

答案B，as...as, 可是加上tall怎么看怎么怪？有人能解释一下tall放在这里做什么用吗？



非常感谢！

这个是定语从句中省略情况，应该说还是挺多的吧。定语从句中只有做宾语时才能省略which，that

这里涉及的是动词recommend的虚拟语气用法，从句中省略should。但好像机考里面现在很少看到。

consist of 动词词组的固定搭配。外貌，appearance，应该看成抽象不可数名词吧，所以不用加复数形式。

C.is taller than the polar bear     D.the polar bear is not as tall

呵呵，因为两个东西不说明的话，没有可比性，蛇的长跟熊的长，概念上有不同，所以必须用tall来表达
