6 The children came ____(run) to welcome the delegation.
注意时态
第三题time 后有个he

Answer 1

1 shut 这是with引导的独立主格结构,因为shut这个动作不是由mouth发出的,所以应该用其过去分词形式
2 having finished 这考的是非谓语动词做状语.因为这个动作发生在主句的动作之前,所以应该用现在分词的完成式
3 to invite 这是做定语,而且动作不是由time发出的,所以不用现在分词,用动词不定式
4 (in) trying have trouble (in) doing sth.是固定词组,其中in可省略
5 will not be 或won't be 根据句意这里应用一般将来时
6 running 这是现在分词做状语表伴随

Answer 2

shutting
Finishing
to invite
trying
will not be
to run

Answer 4

C;what
a
后面接的是名词；how后面接的是形容词或者副词；
A；go
across穿过，go
through通过
