短文改错对介词的考查主要涉及在及物动词后接宾语时误加介词和在不及物动词后接宾语时漏加介词、可直接用作状语的副词短语前误加介词、介词与其他词的常用搭配、常用介词的基本用法、习语中的介词用法等。
动词考点归纳的是除动词时态与非谓语动词之外的动词考点，它包括被动语态、情态动词、动词形式的变化、动词用法辨析、动词 be 的误加与漏用等。
（介词）真题单句归纳：
(1) Suddenly we caught sight at a car and some men. (at 改为 of，catch sight
of是习语，意为“看见”) (全国卷)
(2) When I have free time I go a long walk.(go 后加 for，go for a walk
是习语(全国)
(3) It was very kind for them to meet me at the railway station. (for 改为
of，注意句型 It's kind of sb to do sth) (全国卷)
(4) I was so tired that I fell asleep at the moment my head touched the
pillow. (去掉 at，the moment 在此用作连词，相当于 as soon as)(全国卷)
(5) I feel sorry to him. (to 改为 for，be / feel sorry for sb 意为“为某人感到难过”)
（动词）真题单句归纳
(1)Books may be keep for four weeks. (keep 改为 kept，因此处要用被动语态(全国)
(2) They eager to know everything about China and asked me lots of
questions. (eager 前加were，因此处缺谓语动词) (全国卷)
(3) I'd like to your pen-friend， and get to know more about your country.
(to 后加 be / become，因 would like后要接不定式，根据句意此处应加 be / become)(全国卷)
(4) There will an important game next month. (will 后加be，此处缺谓语动词)
(5)We were all left home at an early age.
(去掉were，因句中已有谓语动词left，“我们离开家”又是主动，不能再加be) (天津卷)
