Example 2:
It has been suggestedthat children hold mistaken views about the 'pure' science that they study atschool. 根据'pure'定位到文中第二段第一行Manystudies have shown that children harbour misconceptions about 'pure' science,curriculum science. 短短一句话我们可以发现有三组四处同义替换，分别为suggested-shown;hold-harbour; mistaken views-misconceptions; science that they study atschool-curriculum science. 因此答案为TRUE。
Example 3:
Some people maybelieve that the teacher- subjects’ behavior could be explained as a positivesurvival mechanism.
可以看出句中positive和survival是关键词，由句中出现的survivalmechanism可判断为是从生物角度来谈论的，又因为原文的F段首句：One’sfirst inclination might be to argue that there are must be some sort of built inanimal aggression instinct that … 中提到了相关内容，所以定位到该段。迅速扫描，搜寻和两个关键词对应的信息，除了在该段第六行出现了原词重现的survival, 还在上一行出现了advantageous, 显然是positive的代换。由于原文跟题目中的信息吻合，所以答案是TRUE。
2. 不同词性的同义替换：
不同词性同义代换顾名思义，就是在代换时不受词性的限制，比如：obvious换成clearly; similar换成resemble等。
Example 1:
Despite substantialfunding, results (of this program) have been disappointing.
代换为：This program failedalthough they received sufficient funding.
因为把disappointing换成了failed, “although”代换了“inspite of”, 通过词的代换就会很自然的实现英文中提倡的句式多样性。
