  1. 1第 1 题

    • A. Unlike
    • B. Besides
    • C. Despite
    • D. Throughout

    答案B

    解析原文“helping you feel close…”先说拥抱让人亲近,后文再谈健康益处,语义上是“除了情感作用之外还有…”。Besides 表递进、附加,正好衔接两层好处。Unlike 强调对比,Despite 表让步,Throughout 表贯穿全程,都无法把“亲近感”与“健康益处”顺畅连起来,故选 B。

  2. 2第 2 题

    • A. connected
    • B. restricted
    • C. equal
    • D. inferior

    答案A

    解析空格与 close 并列,修饰对所爱之人的感受。原文强调拥抱让人感到亲近、有联结,connected 与 close 同向,构成“亲密且相连”。restricted 受限、equal 平等、inferior 低人一等都与温暖拥抱的积极语境相反,搭配也不通,故选 A。

  3. 3第 3 题

    • A. choice
    • B. view
    • C. lesson
    • D. host

    答案D

    解析a ____ of health benefits 表示“大量、一系列好处”。host 有“许多、一大堆”之义,a host of 为固定搭配。choice 选择、view 看法、lesson 教训都不能与 of benefits 组成“诸多益处”的意思,故选 D。

  4. 4第 4 题

    • A. recall
    • B. forget
    • C. avoid
    • D. keep

    答案C

    解析前文说拥抱有益身心,本句“a warm embrace might even help you ____ getting sick”应是“避免生病”。avoid doing 搭配正确。recall 回忆、forget 忘记语义无关;keep getting sick 反成持续生病,与主旨相反,故选 C。

  5. 5第 5 题

    • A. collecting
    • B. involving
    • C. guiding
    • D. affecting

    答案B

    解析study ____ over 400 healthy adults 说明研究的对象规模。involving 表示“涉及、以…为被试”,符合科研表述。collecting 收集、guiding 指导、affecting 影响都不能准确说明“四百多名成年人参与该项研究”,故选 B。

  6. 6第 6 题

    • A. of
    • B. in
    • C. at
    • D. on

    答案D

    解析effects of A ____ B 中,对某事物的影响常用 effects on。此处 hugging 对“易感性”的作用,介词用 on。of/in/at 均非“对…的影响”的惯用搭配,故选 D。

  7. 7第 7 题

    • A. devoted
    • B. exposed
    • C. lost
    • D. attracted

    答案B

    解析受试者被 ____ to the virus 后观察是否感冒。be exposed to 表示“接触、暴露于”病毒,符合实验设计。devoted 献身、lost 迷失、attracted 被吸引语义均不贴切,故选 B。

  8. 8第 8 题

    • A. across
    • B. along
    • C. down
    • D. out

    答案C

    解析come ____ with a cold 是固定短语 come down with,意为“染上、患上(病)”。come across 偶然遇见、come along 进展、come out 出现/出版,都不能表示患病,故选 C。

  9. 9第 9 题

    • A. calculated
    • B. denied
    • C. doubted
    • D. imagined

    答案A

    解析后文给出“约 32 percent”这一具体比例,说明研究者做了量化估算。calculated 计算、测算符合数据呈现。denied 否认、doubted 怀疑、imagined 想象都与给出百分比的客观结论不符,故选 A。

  10. 10第 10 题

    • A. served
    • B. required
    • C. restored
    • D. explained

    答案D

    解析拥抱的减压作用 ____ 了约 32% 的有益效应,即在统计上“解释、说明”了该部分效应。explained 贴切。served 服务、required 需要、restored 恢复都不能与百分数搭配表示归因,故选 D。

  11. 11第 11 题

    • A. Even
    • B. Still
    • C. Rather
    • D. Thus

    答案A

    解析前句已说支持感强更不易感冒;本句进一步:即便感冒了,支持多、拥抱多的人症状也更轻。Even 表让步递进。Still 仍、Rather 而是、Thus 因此都不能准确体现“即使患病仍更轻”,故选 A。

  12. 12第 12 题

    • A. defeats
    • B. symptoms
    • C. tests
    • D. errors

    答案B

    解析感冒后的严重程度对应临床表现,less severe ____ 即症状更轻。symptoms 症状。defeats 失败、tests 测试、errors 错误与病情轻重无关,故选 B。

  13. 13第 13 题

    • A. minimized
    • B. highlighted
    • C. controlled
    • D. increased

    答案D

    解析压力通常会 ____ 感冒风险,拥抱则保护人们免受这一风险。increased risk 增加的风险与常识及后文“压力相关”一致。minimized/controlled 减弱风险则拥抱无需“保护”;highlighted 突出,语义不符,故选 D。

  14. 14第 14 题

    • A. equipped
    • B. associated
    • C. presented
    • D. compared

    答案B

    解析that’s usually ____ with stress:风险“与压力相关”。associated with 为固定搭配。equipped 装备、presented 呈现、compared 比较都不能自然表示“伴随压力而来的风险”,故选 B。

  15. 15第 15 题

    • A. assess
    • B. moderate
    • C. generate
    • D. record

    答案C

    解析拥抱是亲密的标志,并有助于 ____ “他人会来帮忙”的感觉。generate 产生、激发该感受。assess 评估、moderate 缓和、record 记录都不能表示“促成这种被支持的感觉”,故选 C。

  16. 16第 16 题

    • A. in the face of
    • B. in the form of
    • C. in the way of
    • D. in the name of

    答案A

    解析help ____ difficulty:在困难面前提供帮助。in the face of 面对。in the form of 以…形式、in the way of 在…方面、in the name of 以…名义,均不如“面对困境”贴切,故选 A。

  17. 17第 17 题

    • A. transfer
    • B. commit
    • C. attribute
    • D. return

    答案C

    解析专家把拥抱的减压、健康益处 ____ 于催产素的释放。attribute … to 归因于。transfer 转移、commit 承诺、return 归还均无“把好处归结为某机制”之义,故选 C。

  18. 18第 18 题

    • A. because
    • B. unless
    • C. though
    • D. until

    答案A

    解析称之为 bonding hormone ____ it promotes attachment:后半句解释得名原因,because 表因果。unless 除非、though 虽然、until 直到都不能说明“为何叫联结激素”,故选 A。

  19. 19第 19 题

    • A. emerges
    • B. vanishes
    • C. remains
    • D. decreases

    答案C

    解析部分催产素进入血液,但有一些 ____ in the brain。与“释放入血”相对,应是仍留在脑内。remains 停留、留存。emerges 出现、vanishes 消失、decreases 减少都不能对应“部分入血、部分留脑”,故选 C。

  20. 20第 20 题

    • A. experiences
    • B. combines
    • C. justifies
    • D. influences

    答案D

    解析留在脑内的催产素 ____ mood, behavior and physiology,即对情绪、行为与生理产生影响。influences 影响。experiences 经历、combines 结合、justifies 证明合理,都不能作“激素对身心的作用”的谓语,故选 D。
