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。
希望会对你有用！

Answer 2

1. A

so that 表示目的，意思是“他出门戴墨镜，为的是没有人能认出他”
in case 是“以防，万一”，从逻辑上说应该是：
when he went out,he would wear sunglasses in case anybody would recognize him

2. B

这里应该是宾语从句，what 引导的从句做“from”的宾语，同时“what”在从句中做 were 的表语。
