题目内容
18.Be careful!This kind of disease can be easilyspreadeverywhere by some animals.(扩散)分析 小心点!这种病毒很容易通过一些动物到处扩散.
解答 答案:spread
通过分析句子成分可知,"扩散"做谓语成分,故这里的"扩散"为动词"spread".又由"can be"可知,这里为含有情态动词的被动语态,故这里被动语态的构成为:情态动词+be+过去分词.所以这里应该用spread的过去分词为原形,答案为spread
点评 做这道题时应先根据现有句子判断所填词语的词性,然后写出所填词的适当形式. 需要注意的是spread的过去分词较为特殊,为spread.
