6. Remind me _______ the medicine tomorrow.
A. of taking B. taking
C. to take D. take
【陷阱】容易误选A。受 remind sb of (doing) sth 这一常用结构的影响。
【分析】最佳答案为C。比较以下三个结构：
remind sb of [about] sth = 使某人想起某事
remind sb of doing sth = 提醒某人做过某事（暗示动作已发生）
remind sb to do sth = 提醒某人去做某事（暗示动作尚未发生）
请看两个例句：
I reminded him of his promise. 我提醒他做过的诺言。
My wife reminded me of seeing that film. 我妻子提醒我曾经看过那部电影。
Can you remind me to phone her tomorrow? 你明天能否提醒我给她打电话?
7. Once your business becomes international, _____ constantly will be part of your life.
A. you fly B. your flight
C. flight D. flying
【陷阱】几个干扰项均有可能误选。
【分析】最佳答案为D。由于空格后出现了constantly这一副词，这就说明不能选B或C，因为B、C均为名词，不能受副词 constantly 的修饰。A和D均是可能的，因为其中有动词 fly。但若选A，you fly 是一个主谓结构，与其后的谓语 will be 相冲突，所以只能选D，即动名词flying在此用作主语。
8. Not only should you get used ______ under difficult conditions but you also you pay more attention ______ your work well.
A. to work, to do B. to working, to doing
C. to work, to doing D. to working, to do
【陷阱】容易误选A，认为两个空白处均应填不定式。
【分析】正确答案为B，因为 get used to与pay attention to 这两个结构中的to均为介词，不是不定式符号，故后接动词时要用动名词，不能动词原形。类似地，以下各结构中的 to 也是介词，不是不定式符号，后接动词时也应用动名词，而不是动词原形：
look forward to doing sth 盼望做某事
be opposed to doing sth 反对做某事
object to doing sth反对做某事
stick to doing sth 坚持做某事
get down to doing sth 开始做某事
take to doing sth 喜欢上做某事
admit to doing 承认做了某事
pay attention to doing sth 注意做某事
devote one’s time to doing sth 把某人的时间用于(奉献于)做某事
be equal to doing sth 等于做某事，能胜任做某事
What do you say to doing sth 你认为做某事怎么样
9. Both of my parents insisted _______ a computer for me, but I don’t think it is necessary.
A. to buy B. buying
C. on buying D. in buying
【陷阱】容易误选B，误认为insist后不能接不定式，但可以接动名词。
【分析】答案应选C。其实，动词 insist 后既不能接不定式也不能接动名词，因为insist 通常用作不及物动词；若语义上需接宾语，要借助介词 on或upon，即用于 insist on [upon] (doing) sth；但它有时的确也可用作及物动词，不过其宾语通常只能是 that 从句，而不能是普通的名词、代词或动名词。如：
He insisted on seeing her home. 他坚持送她回家。
I insisted that he (should) stay. 我坚持要他留下。
