问题描述：

1No one has yet succeeded in explaining the
___ of how life began.
A cause B problem C Puzzle D reason
2I've never heard such stories ___ Dad tells me.
A as B that C which D what

答

C
D
见《英语沙龙》

答

1.A 意思是至今还没有人能成功解释出生命起源的原因． A和D都是表原因的意思，但A侧重于客观原因，生命起源是因为客观环境的原因而产生的；D侧重于主观推理而得出的原因．
2．A such...as...和such...that...固定搭配都有，但区别在于前者是as引导的定语从句，as代替先行词在从句中充当tells的宾语(tell sb sth)，such...that...引导结果状语从句，此时从句本身应该要完整．以后碰到相类似的题目你只要判断从句是否完整．

答

2.D
such...that...句型
1.B
problem至今还没人成功解释生命怎样起源的难题。其它搭配不当

答

第一题选c 翻译过来就是至今还没人成功的解释出生命的起源的问题
第二题选B 考察so that的变型 SUCH THAT 句型

答

第一题选puzzle,在文中意为生命起源之谜
第二题选as，一个句型，such...as..，意思是
象...一样的

答

d
c
1.生命起源的原因--reason
2.宾语从句
so that是固定搭配，怎么会有such that,误导

答

1.D至今还没有人能成功解释出生命起源的原因。
2.A固定搭配such as

答

C
A
第一题选择 C PUZZLE 名词难题或困惑
翻译过来就是至今还没人成功的解释出生命的起源这一难题.
第二题选A such as 固定用法
例如...,象这种的

答

1、选A. the cause of.....
2、在我认为A、B、D都可以。
当用A答案时构成固定结构：such...as...
当选B、D答案时就构成定语成句，先行词为
stories 。如果 stories 不是复数，那么C答案也
可以用。
不过如只可以选一个的话，最佳答案还是A更好！

答

1C "困惑"
2A "象...的那样"
