本题为一般过去时,所以AC答案不适合.need为实义动词,应用need to do sth的结构
I`m thinking _A_I should do next.
A of what B what C about D over how
因为think of/about 都是考虑的意思.但是需用what来连接 如果选D,则do没有宾语。
she was often heard--C--
A to sing B sing C singing D sung
选C是因为前后两动词同时发生，所以用现在分词作补语
听到某正做某事我们常说：hear sb doing sth
have you sent out the invitations ?
--sorry ,________________.I will do that right away.
A I have forgotten all about it
BI have forgotten it
选A.表示把那件事完全忘记了。

The World Cup will ___ in Tokyo next month.Do you know how many countries will be______?
A.happen,taking part
B. hold, taking part in
C. play ,taking part in
D.take place ,joining in
选D,
happen多指偶尔发生，碰巧发生，所以A答案不适合，hold为及物动词，当应该用被动才对，所以B答案也不对。play的主语应该是用，所以C也不对，况taking part in 后必须有宾语，而后joining in 可以不带宾语。

why didn`t you buy the book ?
I -C- to ,but Iforgot about it.
A liked B wished C meant D expected
mean to do sth 打算做某事.
