be able to的be可以换成is/was/am/were/are对吧
tell sb not to do/ask sb not to do的not在对话中还是用not吗?在什么时候not需要用don't/wouldn't······
!简单点说,好像老师是说过句子开头not需要根据语境变成don't/wouldn't什么的,而在词组中就是用not是不是这样?
希望哪位英语好的帮忙解释解释,一定一定给分啊!
还有ask sb to do =ask sb for吗?如果不是,他们各是什么意思

楼主你好~希望我的回答可以帮助到你>w
再问：那么在词组里not是不能换成别的吧？ He is not going to play computer until six o'clock.=He isn't going to play computer until six o'clock也可以吧？
再答：首先说清楚一个概念： is not=isn't are not=aren't should not=shouldn't 像isn't, aren't, shouldn't叫缩写词汇。你把他们缩写以后，并没有把not改变成另一个词，只是把两个词缩短了而已就好像苹果软件店Apple store都会缩写成App store一样， apple这个词看起来没有了，但是实际还是这个词在词组里。所以，he is not going to....=he isn't going to....^-^是对的哦！
再问：那么在词组里not是一定不能换成别的吧。
再答： =.=是啊基本的意思不能变吧。通常都是不能换的，除了换个说法以外。如果你真要逆袭改写句子，除非是：ask sb. stop doing something.（叫某人停止再做某事，稍微改变原义 prevent sb. from doing sth.（防止某人做某事，同样达到了ask sb. not to do的原义，并且没有出现not。
