【解析】

试题分析: 文章介绍了美国研究人员正在研究一种新的消除记忆的药片，引起了人们的广泛讨论。

1.which考查定语从句。指代前面整个句子，引导非限制性定语从句，故用 which。

2.to be taken 考查固定用法。前面是被动语态，后面再接动词就要用不定式，句意是表被动，因此写成to be taken。

3.possibly 考查副词用法。副词修饰动词，因此写成possibly。

4.releasing 考查固定用法。Stop……from doing sth,因此写成releasing。

5.has suggested 考查时态。so far是指到目前为止，常与现在完成时连用，故答案为has suggested。

6.argument 考查词性转换。研究引起大量的争论，空格处要填名词，因此用argument。

7.a 考查冠词用法。一个坏主意，肯定用a.

8.However 考查连词用法。表前后句的转折关系，因此用However。

9.against 考查介词用法。前面是支持者说的，中间有转折连词，因此后面肯定是反对者，因此用against最佳。

10. 考查词性转换。此处意思是非常危险的，系表结构，应用形容词，故写dangerous。

【名师点睛】

限制性定语从句与非限制性定语从句的区别：

一、在书写形式上,限制性定语从句紧接着主句写,非限制性定语从句和主句隔开.

He is a man who has won six medals.

He is a man,who has won six medals.

二、限制性定语从句对先行词有限制修饰的作用,使得先行词具有区分于其它同类事物的特点.

It is the tree I planted three years ago.

这是我三年前栽种的那颗树（不是其它的树）.

而非限制性定语从句并没有上述作用,相反,它是对先行词起补充说明的作用.

It is a tree,which I planted three years ago.

这是一颗树,我三年前栽种的（补充说明树栽种的时间）.

三,限制性定语从句对先行词具有限定性,非限制性定语从句体现先行词的唯一性.

John likes his father who has studied abroad.约翰喜欢他出国学习过的那个父亲（给人感觉他另外还有其它没出国过的父亲）

John likes his father,who has studied abroad.约翰喜欢他的父亲,他父亲出国学习过.（约翰的父亲是唯一的）

四,语法区别.常考的一点是：非限制性定语从句修饰物,关系代词只能使用which,不能用that.

It is a tree,which I planted three years ago.

It is a tree,that I planted three years ago.(错)
