是 talk of 还是 a lot of

是 talk of 还是 a lot of

请看下面的这道题，是考查 talk of 还是考查 a lot of？

We’ve talked a lot __________ cars. What __________ trains?

A. of, of                         B. of, about                      C. about, of                   D. about, about

此题应选 D。容易误选A，B(尤其是误选B)。后面一空填介词 about, 这比较好理解，但第一空很容易受 a lot of 这一短语的影响，而误选A，B。

假若第一空填介词of, 从而构成 a lot of, 很显然句中的a lot of cars 应该是动词 talked 的宾语，然而事实上动词 talk 是一个不及物动词，所以这种分析是不成立的。

此题第一空应填about, 其原因是：句中的 a lot是修饰动词 talked 的状语，talk about才是一个动词短语。 全句意为：我们对汽车已谈了不少，现在谈谈火车怎么样?

请做以下各题(注意所填的介词到底是与哪个词搭配)。如：

1. We keep in touch _________ writing often.

A. with                     B. of                     C. on                        D. by

2. We all regarded the poor old man ________sympathy.

A. as                        B. with                  C. of                         D. by

3. We’ve decided to leave _________ the farm at once.
