He had better do some r______. he had better do it now改成一般疑问句怎么改呢? he had better do it now.当He had better do it now.变否定句时加not,not应加在better前还是better后,为什么?请说的详细一些. 谢谢!谢谢!谢谢!谢谢!谢谢!谢谢!谢谢! it is better for sb to do than do = sb had better do had better do=? 变一般疑问句:You had better do it. You had better start to do it right now.翻译. had better do sth和it is better to do的区别 It's better do 还是 to do 那had better do 等better用法麻烦讲一下 had better not do sth Is it right?我问的是语法是否正确：had better not do sth 是had better to do还是had better do had better do还是had better to do had better +do sth 还是had better +to do sth had better(not) do sth... had better do等于什么 It had better be good. I had better ___(do/to do) 有Had he better do sth 这种句型吗急用 知道的说 别误导我
