apple a day keeps the doctor...”可知,此处表达的是“医生远离”,应用away。故选D。3.C【解析】句意:做运动对孩子来说是最受欢迎的活动之一。本题考查动名词短语做主语。分析句子可知,缺少主语;动词短语play sports做主语,要改为动名词短语,故选C。4.A【解析】句意:——

lies。根据句型It is better to do sth“做某事更好”,故第二空用动词不定式to tell a white lie。than前后比较,than前面是动词不定式,故than后面是动词不定式to tell someone a painful truth,故选C。62.D【解析】句意:珍妮想成为校报的一名作者终于梦想成真了。考查非谓语。分析句子结构,第一空作主语,应用不定式或动名词,排除A/C选项;第二空是短语a dream come true“梦想成真”,动作已完成,应用过去分词作定语,故选D。63.D【解析】句意:阅读能帮我们了解很多有关世界的情况。考查动名词作主语和词汇辨析。句子中已有谓语动词“can

English做主语时,需要变成动名词形式learning English,固定句型be important to“…对某人而言是很重要的”,而介词for 多用于句型be important for sb to do sth.做某事对某人重要,故选A。65.A【解析】句意:不要玩火。玩火是危险的。 考查祈使句和动名词作主语。第一个空是否定祈使句,其构成是:Don’t+动词原形;第二个空是主语的位置,因此应该用动名词形式,首字母大写。故选A。21世纪教育网(www.21cnjy.com)21世纪教育网(www.21cnjy.com) 展开更多...... 收起↑ 资源预览
