不好意思哦 打的晕了

1、act及物名词 bd语义不对 用seem的地方一般可用is带 搭配有问题
2、need两种用法：sb. need do 这里的need永远都是原型 因为是情态动词 否定为 needn't；sb. need to do 这里的need为实义动词 按一般动词变形 这里ab语义不对need为情态动词时语义与have to意思相近 但need表义务 have同表客观不得不 但这里need无to 不能用dont 实义动词与情态动词要分清
3wonder为动词 后面两种从句宾语和状语 就语义谓宾语从句do后面又缺宾语只能用what不能用其他（仅限宾语从句）后面不缺成分时（主、宾）用when、how、where
4逻辑上你只能选一种both你就太贪心了 并且只有两种
5b知道c realize只用一般式 不加助动词 notice注意到
6act a role of ; play a part in固定搭配
7制度上的带有强制约束力用must 法律文件用shall should表应该处于义务责任的 would用作虚拟语气 could表可能等 情态动词用法复杂 建议上网看语法
