Question

1.Since he left the university,he____in an accounting compan？

Answer 1

1.A
since引导时间状语从句时,其主句只能使用现在完成时或现在完成进行时.
2.C
比较必须是同类事物,所以用that代指不可数名词the weather.
即：that in America = the weather in America.
而one代指的是可数名词单数.
3.B
此题为not until句型的强调句型：It was not until + 时间状语 + that + 句子（肯定句）.因为句子的not已经提前,所以后面必须还原成肯定句.
不采用强调句型为：They didn't find their way out of the forest until dawn.
4.A
主语从句______he says or does中,谓语动词says/does均缺少宾语,所以用whatever.
而BD均为副词,不能做宾语；which表示选择,与句意不符.
5.C
take on意思是“承担”,其他短语均无此意.,8,1 A since 主句用完成时
2 C that代替weather
3 B it was....that强调句
4 A 引导主语从句
5 C take on 承担,2,ccbac,2,1 A。因为有since引导的时间状语从句，主句应用完成时，从句为一般过去时，所以主句是现在完成时，has been doing是现在完成进行时，到现在为止一直做某事的意思。
2 C。that 代替前文提到的不及物动词，在本句中就是weather。句意：中国的天气和美国很不一样。
