这样看来，可以确定排除的选项是C和D，而A提到的记忆力与第二个实验的关系比较大，很有可能是迷惑选项，这样最好是选择B。(C)
34. In the experiment described in Paragraph 3, the video-watchers experienced a downturn in the antibody because ________.
A) the video was not enjoyable at all
B) the outcome was beyond their control
C) they knew little about surgical procedures
D) they felt no pressure while watching the video(B)
题目问在第三段所描述的实验中，观看视频的人经历了抗体的减少，原因是什么。
文章第三段提到阿姆斯特丹的这所研究中心进行了一项研究，研究分为两组(two stressful experiences)，不过文中只描述了其中观看视频的一组，另一组的具体情形没有描述。而从全段来看，这缺失的一组对本题的回答是有帮助的。因此，可以猜测这里在排版时很可能又漏掉了一些内容。另外，对第一组实验的描述也存在问题。In the first, a timed task that required memorizing a list followed by a short test, subjects through a gory video on surgical procedures，分析这个句子可知它没有谓语，可以把a timed task看作是主语，that required memorizing a list是主语的定语从句。而followed by a short test是个省略了which的定语从句(which was followed by a short test)，所以follow不是谓语。对follow不是谓语的判断源于by这个词，既然有by，就表示followed是被动语态，那么一定要接在was后面，但这里was省略了，可以就此判断这是个定语从句。这样的话，前半句没有出现谓语，那么后半句呢?后半句中没有一个动词，所以根本不可能存在谓语;subject可以作为动词使用，表示“隶属于”，但文章使用的过去时态，subjects是一般现在时，不符合语法，所以subject不是动词。
这样只能认为这又是一个错句。如此多的错误出现在关键部位，文章的理解尚成问题，也就谈不上正确回答问题了。
A，因为视频一点也不好看。
B，这一结果是他们无法控制的。
C，他们对外科手术过程知之甚少。
D，观看视频时他们感觉不到压力。
35. Dr. Bruce McEwen of Rockefeller University believes that ________.
A) a person’s memory is determined by the level of hormones in his body
B) stress hormones have lasting positive effects on the brain
C) short bursts of stress hormones enhance memory function
D) a person’s memory improves with continued experience of stress
题目问Bruce McEwen医生认为什么。
可以看出本题考查的是对最后两小段的理解。这两段不难理解，其核心意思是短期压力对人有益，长期压力对人无益。
A， 人的记忆力是被身体里的荷尔蒙水平决定的。根据文意，荷尔蒙对人的记忆力产生了一定影响，但称其“决定”了记忆力水平就太夸张了。
B， 压力荷尔蒙对大脑有持续的积极影响。文中谈到长期的压力荷尔蒙对人有害(Sustained stress is not good for you)，与本选项正好相反。
C，压力荷尔蒙的短期爆发会加强记忆功能。In short bursts these hormones have a positive effect, including improved memory function，这一句与C的说法完全一致。
D， 随着人不断感受到压力，人的记忆力也随之改善。continued experience of stress可以理解为长期的压力，而根据文意，这种压力对人体是有害的。
C的说法正确。
Passage Four
Questions 36 to 40 are based on the following passage.
If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.
If you say to your children “I’m sorry I got angry with you, but ...” what follows that “but” can render the apology ineffective: “I had a bad day” or “your noise was giving me a headache” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.
Another method by which people appear to apologize without actually doing so is to say “I’m sorry you’re upset”; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.
