1、巧记动词不定式基本用法口诀
不定式有标记,to与动原连一起。 to do sth 没有人称数变化,动词特点它具备。 主宾定补表状语,唯独作谓不可以。
not加上不定式,否定结构要牢记。 not to do
疑问词与不定式,构成短语有意义。 what / how/ when/ where... to do 仔细推敲多思考,准确判断有依据,
2、巧记接不定式做宾语的动词
开始希望能答应(begin,start,expect,hope, wish, want, agree, promise) 努力要求莫拒绝(try,demand,order, refuse) 设法学会做决定(manage, learn, decide) 不要假装在选择(pretend, choose)
3、巧记少数后面只能用动名词做宾语的动词
考虑建议盼原谅,(consider, suggest / advise ,look forward to ,excuse ,pardon ) 承认推迟没得想,(admit, delay / put off , fancy) 避免错过继续练,(avoid , miss ,keep /keep on , practice) 否认完成停能赏,(deny , finish , stop ,enjoy / appreciate) 不禁介意准逃亡,(can’t help , mind , allow/ permit ,escape) 不准冒险凭想象。(forbid , risk , imagine)
4、巧记既可以跟动名词也可以跟不定式的动词
双方一旦开始,不论喜欢与否,都得继续下去。 不管记住与否,努力打算停止,后悔三个需要。 begin , start ,like ,love, prefer , hate ,dislike ,continue,remember , forget , try , mean , stop , regret , want , need , require
其中有一些后接动名词和接不定式表达的意思不同:
1) 三个需要很常用,动名作宾语表被动,不定式作宾语表主动.
to be done 需要
need/want/require doing 需要
sb. to do sth. 需要/要求/想要 eg. I need to go now=I want to go now=I require to go now. 我得走了
The chair needs repairing=The chair needs to be repaired. 这个凳子需要被修理 2) stop to do开始做, stop doing停止做
try to do努力做, try doing试一试 mean to do 打算做 mean doing 意味着做 regret to do 很遗憾要去做 regret doing 后悔做过
remember/forget to do 记得/忘记要做 remember /forget doing 记得/忘记已经做过 eg. Stop to listen to me=Stop what you are doing and begin to listen to me.
