考查音标异同。present中的划线部分读/e/，prevent中的划线部分读/i/，huge中的划线部分读/ju/，push中的划线部分读/u/，remain中的划线部分读/ei/，painful中的划线部分读/ei/。故选C。
10．B
【详解】句意：——你觉得《我和我的祖国》这部电影怎么样？——非常好，非常值得一看。
考查形容词辨析。useless没用的；worth值得的；successful成功的；busy繁忙的。根据“What do you think of the film”及“very good”可判断，电影值得看，be worth doing sth表示“值得做某事”。故选B。
11．is well worth watching
【详解】由语境和英语翻译可知，“非常值得做某事”译成：be well worth doing sth.；“看”译成：watch。此处的主语The documentary是单数，因此be动词用is。故填is well worth watching。
12．have problems in preventing the spread of the disease
【详解】做某事有困难：have problems in doing sth；阻止疾病的传播：prevent the spread of the disease，用动名词作宾语；故填have problems in preventing the spread of the disease。
13．great difficulty people have preventing the spread of the virus
【详解】根据汉语提示可知是感叹句，其结构是What+形容词+不可数名词+主语+谓语！What great difficulty people have“人们有的多么大的困难”；短语have difficulty doing sth.“做某事有困难”；the spread of the virus“病毒的传播”；prevent“阻止”，是动词，此处用动名词，故填great difficulty people have preventing the spread of the virus。
14． worth watching
【详解】根据中英文对照可知，缺少“值得一看”。worth“值得”，worth doing sth.“值得做某事”；watch“看（电影、电视等）”，此处要用动名词watching。故填worth；watching。
15． had no choice but to##had no alternative but to##has no choice but to##has no alternative but to in order to prevent the rapid spread of/so that he could prevent the fast spread of/so that he can prevent the fast spread of
【详解】根据语境可知，此句既可用一般过去时描述过去发生的事情，也可用一般现在时陈述观点或事实。根据中英文对比可知，第一空应填“除了……别无选择”的英文表达，即短语“had/has no choice/alternative but to...”。第二空中“为了……”既可翻译成介词短语“in order to do sth.”作目的状语，也可翻译成“so that”引导目的状语从句；“阻止……的快速传播”可翻译为“prevent the rapid/fast spread of...”。故填had no choice but to/had no alternative but to/has no choice but to/has no alternative but to；in order to prevent the rapid spread of/so that he could prevent the fast spread of/so that he can prevent the fast spread of。
16． keep##stop##prevent from
【详解】根据“must”可知，情态动词后加动词原形；阻止某人做某事：keep/stop/prevent sb. from doing sth.。故填keep/stop/prevent；from。
17．greatly encouraged
【详解】表达“鼓励”用动词“encourage”。主语“I”和动词之间是被动关系，表达被鼓励用“was encouraged”。表达“极大地”用副词“greatly”修饰动词过去分词“encouraged”。故填greatly encouraged。
18． stop##keep##prevent spreading
【详解】根据中英文可知，此处空对应的中文为“阻止”，“传播”。stop/keep/prevent…from doing表示“阻止……做……”；spread“传播”。try to do“尽力做某事”，此处第一个空使用动词原形；第二个空使用动名词。故填stop/keep/prevent；spreading。
19．(p)revent
【详解】句意：锻炼帮助预防心脏病。help to do sth.表示“帮助做某事”，其中to可省略，即help do sth.。根据语境可知锻炼身体可以帮助预防心脏病，首字母为p，因此应用动词prevent。故填(p)revent。
20．(p)revent
【详解】句意：经常用肥皂和水洗手是防止疾病的一种好方法。表达“阻止疾病”用短语prevent the illness。根据句型“a good way to do”的意思是“一种做某事的好方法”可知。空格处应该用原形。故填(p)revent。
