作文
1. In this task, you are to write an essay on the necessity of developing social skills for college students. You will have 30 minutes for the task. You should write at least 120 words but no more than 180 words.
The necessity of developing social skills for college students can never be overstated. As an important transferable skill, the ability to socialize is essential to a student’s development on and off campus. Specifically, socially smart students tend to achieve better academic performance and get more job opportunities.
For one thing, effective communication and teamwork are often required in many scenarios on campus, such as working on a group assignment or participating in a team sport competition. Students who harness social skills can work more closely with their teammates and navigate more quickly through these tasks and challenges. For another, those who are more proficient in socializing will make more friends and are more likely to find potential jobs through their acquaintances.
To conclude, developing social skills is necessary and rewarding for college students, as it not only secures a student’s success in assignments and competitions, but also brings various job opportunities.

2.【C1】
L
解析：空格位于两个表时间的介词短语in follow-up periods和from three to 21 years之间，本句主干为there-be结构，因此空格处考虑填入非谓语动词。由2个介词短语的语义可知，“为期3年到21年”是对“在随访期间”的时间跨度的补充说明，因此空格处应填写描述时间跨度，且能与介词from…to搭配的非谓语动词。代入ranging“(在一定的范围内)变化”，表示“从3年到21年的范围”，符合此处语境，故选L。
3.【C2】
H
解析：空格位于主语three of the papers和名词loneliness之间，句子缺少谓语，且空格所在段落用一般过去时，因此空格处应填入动词过去式。根据下文的18 looked at social isolation and two included both“18 篇研究了社交孤立，2篇同时涵盖了这两方面”，可知空格处填入的词应与looked、included并列，表示“研究，探讨”的含义。词库中的measured“评估，判定”符合要求，故选H。
4.【C3】
B
解析：空格位于and连接的名词短语中，因此空格处考虑填入复数名词，与and前的medical records并列，与death构成名词短语。词库中的复数名词有certificates“证明”、differences“不同，差异”和formats“版式”，因空格处填入的是与records“记录”意思相近的词，故排除differences和formats。代入certificates，表示“死亡证明”，语意通顺，故选B。
5.【C4】
M
解析：空格位于定冠词the和名词risk之间，因此空格处考虑填入定语修饰risk。根据文章第1段可知，科学家研究的是“社交孤立或孤独与冠心病和中风患病的风险增加”的关系，故空格填入表示loneliness and social isolation“孤独和社交孤立”与having a heart attack or a death from heart disease“心脏病发作或死于心脏病”相关的词。代入形容词relative“相对的”，the relative risk意为“相对危险度”符合此处语境，故选M。[“相对危险度”也称为“危险度比”，是暴露组的危险度(测量指标是累积发病率)与对照组的危险度之比。]
