【解析】
这是一则讨论对新型冠状病毒流行的恐惧,以及对政府采取的措施的一些个人看法和观点的情景对话。
【1】句意:我听说在英国,人们需要待在家因为COVID-19的快速传播。
根据句意表示COVID-19的快速传播,句子成分分析,空格处缺少名词,表示传播。故答案填spread。
【2】句意:在我待在家里的头2个礼拜期间,我每天不能停止看手机去关注它的发展。
根据句意表示不能停止做……,短语be unable to do sth.不能做……。故答案填unable。
【3】句意:看到感染和死亡人数的急速增长。
联系下文“I feared that the virus might make me sick.”我很怕这个病毒会让我生病,可知,是急速增长,此处要有形容词修饰其后名词numbers,副词rapidly修饰该形容词。故答案填increasing。
【4】句意:你确实得到了信息。
联系下文“And every day there is tons of the information,”每天有大量的信息。可知,是信息的意思。故答案填information。
【5】句意:记住你不是不正常的。
联系下文“These are normal feelings at this time.”这个时候有这种感觉是正常的,说明你不是不正常的。故答案填abnormal。
【6】句意:在全国人民的共同努力下,我们国家的情况好多了。
根据句意表示共同努力之下,effort努力,可数名词,用复数形式。故答案填efforts。
【7】句意:它可以鼓励世界各地的人们赢得抗击新冠肺炎的战争。

【10】句意:这就是最大的差异——我们西方人认为口罩是给病人用的,而不是给健康的人用的。
根据句意表示最大的差异,大的big;the定冠词后用最高级。故答案填biggest。
【题目】 Do you know viruses (病毒) and bacteria (细菌)? Both of them are very small, we can't see them with our eyes, and many people know nothing about them, In fact, there are a number of differences between viruses and bacteria. Bacterium, the singular form of the word bacteria, is a one-celled (单细胞) living thing, with complete sets of both RNA and DNA genetic codes (遗传密码). For viruses, some are sections of RNA, and the others are sections of DNA. So, bacterium is at least a hundred times larger than a typical virus.
One main difference between viruses and bacteria is the method of reproduction. A bacterium is a completely independent and self-reproducing unit. When the time is right, bacterium will divide its DNA and RNA genetic material in two. This is how bacteria live in almost every environment on Earth, including non-living things like rocks or plastic.
A virus, on the other hand, cannot reproduce without a living host. A virus may lie for thousands of years before finally coming into a suitable host. Once it enters the body of a host, a virus will get in the ling cell. Once inside a living cell, a virus takes the place of the living cell's DNA or RNA genetic instructions with its own. Those instructions are usually to make as many copies of the virus as possible.
Ninety-nine percent of all known bacteria are considered useful to humans, or at least have no bad influence. But most viruses, on the other hand, serve no good purpose. Their only purpose is to create more viruses in order to make themselves continue to live.
Bacteria are alive, which means they can be killed by some form of chemical things. Antibiotics (抗生素) can kill bacteria. Viruses, by comparison, are not considered living things. They cannot be 'killed' in the same way as antibiotics kill bacteria. In fact, any medicine is useless for virus' infections. The disease must run its course until the body can make a successful protection on its own.
Viruses and Bacteria | |||
Similarity | Both are too small 【1】 with our eyes. | ||
Differences | Viruses | Bacteria | |
What they're like | ● They are not living things. | ● They are living things. | |
● A virus is a section of 【2】 RNA 【3】 DNA. | ● A bacterium has complete sets of both RNA and DNA genetic codes. | ||
● A virus is much smaller than a bacterium. | |||
How they reproduce | A virus can not copy without a living host | A bacterium can reproduce 【4】 in almost every environment on Earth. | |
How they influence humans | Most of them do 【5】humans. | Most of them are considered useful to humans, or at least have no bad influence. | |
【6】for viruses and bacteria | We can use antibiotics to kill bacteria while for viruses it only depends on if our body can make a successful protection on its own. | ||
