问一下这个英语题的答案和解析

1、when he went out,he would wear sunglasses___nobody would recognize him A so that B in case 2、with the introduction of the computer ,libraries today are quite different from___ they were in the past A that B what C which D those

Answer 1

1.in
case是假使，免得的意思，它可用于句首或句中，如In
case
she
comes
back,
let
me
know
immediately/Take
the
raincoat
in
case
it
rains。用在这里，意思不匹配
so
that是指所以，因此；为使，以便，选A，整句话的意思是他出去时会戴一副太阳眼镜，以便没人能够认出他。
2。首先those是绝对不可以选的，that和which都可指物，都可引导从句，只是这句话关键在于
they
were
in
the
past，这里缺少的是were后面的一个宾语，what可替代这个部分。而that和which则用不来。整句话的意思是有了电脑的介绍帮助，现今的图书馆与过去很不一样。
