I --- to get up early
Adid not use Bdid not used C do not useDdo not used

选 A
used to do sth 过去常常做某事
did 是助动词,后面跟动词原形 use

再问：为什么不选C呢还有这题呢It -- that he has been ill for a long time Aseems B looksClooks like Dseems like
再答：因为used to do sth 表示过去常常做某事 used 是过去式，所以助动词必须用 did 选 A seems that 从句是现在完成时，主句用一般现在时和它对应，都属于现在的时态。
再问：第一题我是问为什么不是一般现在时呢第二题我知道主句是一般现在时但为什么选择A呢能说说ABCD选项的区别为什么选A呢
再答：第一题根据四个选项可以判断要表达的意思是：我过去常常不早起。只能用 used to do 结构，没有use to do 的用法。第二题用的是固定句型：It seems that +从句意思是：他似乎已经病了很长时间了。选项 B looks 表达不出似乎的意思选项C looks like 意思看起来像，后面不能跟 that 从句选项 D 搭配错误，没有 seem like 的用法
再问： -----you -----stay at home today A Do .have to B Must .have to C Have. to D Do. must
再问： -----you -----stay at home today A Do .have to B Must .have to C Have. to D Do. must
再答：选 Amust 和 have to 不能混用，排除 Bhave to 用助动词 do 构成疑问句，排除Cmust 是情态动词，不能和助动词 do 连用，排除D
