一、In a recent study _____ over 400 healthy adults, researchers from Carnegie Mellon University in Pennsylvania examined the effects of perceived social support and the receipt of hugs _____ the participants' susceptibility to developing the common cold after being _____ to the virus.
1) A collecting
B affecting
C guiding
D involving
involve 牵涉
这里是根据语境来进行思考的，很明显A、B、C都不符合文中的题意，只能选择D选项
2) A on
B in
C at
D of
这道题涉及到固定搭配，examined the effects ... on sth.
所以选择A选项
3) A devoted 致力于
B attracted 吸引
C lost 丢失
D exposed 暴露
那很明显，这里是容易得到感冒是因为会暴露在病毒之下，所以选择D
二、People who perceived greater social support were less likely to come _____ with a cold, and the researchers _____ that the stress-reducing effects of hugging _____ about 32 percent of that beneficial effect.
1) A along
B across
C down
D out
这道题是固定搭配，come along with 和...一起，随同
come across with 偿付
come down with 得病，感染
come out with 出版，提出
那很明显，这里是感染了，所以选择C选项
2) A imagined
B denied
C doubted
D calculated
根据后文中的32 percent数字的内容，先进行大胆的猜测，选D，因为D的选项是计算的意思，再将D选项的意思带入到原文中，很明显是正确的，这是调查人员计算得到的结果
3) A served 服务
B restored 存储
C explained 解释
D required 要求
这里很明显又是考察单词在句子中的定义问题了，那么C选项是最符合的
