Question

1.--- It's many years since I saw you last，I ___ you at all.

Answer 1

正确答案是d.
how
much除了被用来问钱问不可数名词的数量外,还可以被用来问程度!
如:
how
much
is
this
book?
how
much
water
is
there
in
the
cup?
请看这个例子:
i
love
her
very
much.
如果问你有多么爱她的时候,应该说:
how
much
do
you
love
her?
同理,本题也是表达"我是多么地想再次看到你",所以说:
how
much
i
want
to
see
you
again.
本句因为是宾语从句,所以没有倒装,用了陈述句序.

Answer 2

A
过去式，表明之前没有认出来，C是现在完成式，表示到现在都还没认出来，if
have
done表示对过去的虚拟，如果当时怎么样
所以选A
A
make/think/consider
it
形容词或名词
to
do
一个句式，it
是
形式宾语
，真正的宾语是to
do
