答案以及解析
1.答案：C
解析：考查状语从句。

句意：政府号召我们，若非确实必要的话，不要去人群密集场所和医疗机构。

2.答案：B
解析：考查状语从句。

句意:虽然这种方法在减肥方面很有用,但是它不如保持平衡的饮食更有益。

while放在句首此处表示“虽然”,引导让步状语从句。

3.答案：B
解析：考查从属连词辨析。

句意：在对新冠肺炎进行实验后，专家得出结论：这个病毒存活几率非常大，即使已感染者两次检测都呈阳性。

所以选B.
4.答案：C
解析：题目考查并列连词。

句意:我不害怕未知的明天,因为我已经经历了昨天并且深爱着今天。

So后跟结果;and表并列关系;but表转折;for补充说明原因,故选C。

5.答案：B
解析：考查连词。

or 表选择关系;and表并列关系;so和for表因果关系。

句子前后是并列关系,所以选B。

6.答案：while
解析：while表示前后两种情况的对比, 意为“而”。

7.答案: when
解析:be doing sth. ...when 为固定句型,表示“正在做某事......这时......”。

8.答案：but/yet
解析：句意为:然而,最重要的是,记住下面的规则:尽力去吃不同的食物,但不要吃太多。

由句意可知,设空处前后内容之间为转折关系。

故填but或yet。

9.答案：unless
解析：句意为:除非你完全投入到你的工作中,否则你将永远不会获得成功。

由句意可知,此处应填unless,意为“除非”,引导条件状语从句。

10.答案：because/as
解析：空后的“它能让我放松并让我忘掉一天中的其他烦恼"与空前的“我真的非常喜欢听音乐”之间为因果关系,且后面是前面的原因,故填as/because。

11.答案：where
解析：句意为:让我们从昨天结束的地方开始,这样我们就不会错过任何东西。

设空处引导状语从句,在从句中作地点状语,所以应用where引导该从句。

12.答案：I glanced at my watch. It was earlier that
than
I thought.
解析：
由句中的earlier可知，此处应是在做比较，故用than引导比较状语从句。

13.答案：Most of our parents like listening to old songs when
while
young people prefer pop songs.
解析：句意:我们父母中的大多数喜欢听老歌而年轻人更喜欢流行歌曲.while作并列连词表示对比.
14.答案：I’d just a bout given myself up for lost while
when
I was spotted by a ship.
解析：句意:我刚要放弃了自己,就在这时,一艘船发现了我。

根据句意和结构可知,该题考查的是固定搭配be about to do sth. when……意为“刚要做某事,就在这时……”,所以应该把while 改为when,when在这里是并列连词。

15.答案：Many scientists got hurt when they were doing experiments, so
but
they didn’t give up.
解析：
分析句意可知，此处为转折关系，故用but。

句意:很多科学家在做实验时受伤，但是他们没有放弃。
