第一句：(不是线索句，没有资格和选项进行比对)
A seasoned psychiatrist, Heilig joined the National Institutes of Health in 2004 with grand ambitions of finding new ways to treat addiction and alcoholism.
词汇突破：
1. seasoned 经验丰富的
2. addiction and alcoholism ;addiction一般不明确说是什么上瘾那就是(毒瘾)alcoholism(酒瘾)
3. with grand ambitions 雄心勃勃的
切分：
1.A seasoned psychiatrist, Heilig joined the National Institutes of Health in 2004
2.with grand ambitions of finding new ways to treat addiction and alcoholism.
参考译文：作为一名经验丰富的精神病学家，Heilig于2004年加入了美国国立卫生研究院，雄心勃勃地寻求治疗毒瘾和酒瘾的新方法。
(A) he is a skilled psychiatrist with the help of National Institutes of Health.
这个选项看上去和第一句有关，但是和题干没有关系啊!
所以首先就是定位错误!A选项就不是问题要找的原因!排除!
第二句：
“It was the age of the neuroscience revolution, and all this new tech that gave us many ways of manipulating animal brains,” he recalls.
词汇突破：
1.the neuroscience revolution 神经科学革命
2. manipulating animal brains 操控动物大脑
切分：
去掉强调句格式:
1. the age of the neuroscience revolution, and all this new tech gave us many ways of manipulating animal brains
2.he recalls.
参考译文： “正是是神经科学革命的时代，所有这些新技术给了我们操纵动物大脑的多种方式，”他回忆说。
(B)the new tech of neuroscience enables us to manipulate animal brains
这个选项看上去和这个句子有关，但是这个句子不是线索句啊!这个选项也不是题干要找的原因!排除!
第三句：(线索句：有资格和选项进行比对的句子!)
By studying addictive behavior in laboratory rats and mice, he would pinpoint crucial genes, molecules, and brain regions that could be targeted to curtail the equivalent behaviors in people.
词汇突破：
1.rats and mice ：实验鼠和小鼠
2. pinpoint：确定
3. crucial genes, molecules, and brain regions：关键的基因、分子和大脑区域
4. curtail 限制
5. equivalent behaviors 等效行为
切分：
1.By studying addictive behavior in laboratory rats and mice,

2.he would pinpoint crucial genes, molecules, and brain regions that could be targeted to curtail the equivalent behaviors in people.
他可以确定关键的基因、分子和大脑区域，以限制人们的等效行为(各种瘾)。
重要思路：
既然题干认为1是结果，那么2就是原因!
真题链接1：
题干：
Washington’s decision to free slaves originated from his________
原文：
Washington, who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will.
切分：
1. Washington overcame the strong opposition of his relatives to grant his slaves their freedom in his will.
2.who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War
题干认为1 是结果，那么原因就是2.
真题链接2：
题干：
As a result of President Bush’s reform, retired people may have_______
原文：
For much of the past year, President Bush campaigned to move Social Security to a saving-account model, with retirees trading much or all of their guaranteed payments for payments depending on investment returns.
切分:
1. For much of the past year, President Bush campaigned to move Social Security to a saving-account model,
2. with retirees trading much or all of their guaranteed payments for payments depending on investment returns.
题干认为1 是原因，那么2 就是结果。
回到本题：
he would pinpoint crucial genes, molecules, and brain regions that could be targeted to curtail the equivalent behaviors in people.
所以答案只能是C!
(D)he has found the addictive behavior in laboratory rats and mice
首先D和这个部分就不匹配!
再看：
(C)the result of study is helpful for us to erase the addictive behaviors in people.(完美替换!)
有同学可能会觉得用erase 替换curtail程度过深。
但这就是真题的套路，不会那么完美的替换。
