急需一道初中英语选择题{要有答案和分析}!!

Answer 1

- _______did your uncle leave his hometown?
-He ____________ for nearly 2o years.
A.When, has left
B.When, has been away
C.How long, has been away
D.How long, has left

选B
第一空因为后面是“did” 一般过去式，所以接短暂性时间副词，即when。故排除C，D，因为How long 是询问时间段，一般接完成时态。
第二空因为后面是"for"表示一段时间，所以选用表示状态的完成时态，即has been away。 has left 表示已经离开这一事实，而has been away表示离开中的状态。

希望对你有帮助:)

Answer 2

It is better to teach a man to fish than ________ him fish.
A. to give B. giving C. to find D. finding
than作为一个连词，前后的格式应该一样。前面是to do后面也应是to do
than后面的形式要和前面一致。前面是to fish这里的fish是动词打鱼（渔）
后面的to give him fish这里的fish是名词鱼

Answer 3

Hurry up, Jack. We have to get to the station before 11:45 _____ we can catch the 12:00 train.
A. since B. after
C. as soon as D. so that
[解题技巧]
以此立意的试题考查考生能否正确使用连接目的和结果状语从句的一组连词so, so that。“为了……”“结果……”。
本题是一个目的状语从句“为了能赶上12点的火车”，选D。
