【答案】

1Has visited

2haven’t finished

3Yes have No haven’t

4Yes has No hasn’t

5How many has

【解析】

1句意:她以前来过中国。

根据句意理解可知,句中用的是现在完成时,所以变成疑问句时,要把完成时的助动词提前,原句中用的是has,所以直接把has提前,后面的过去分词不变,故答案为Hasvisited

2句意:我已经写完作业了。

根据句意理解可知,原句用的是现在完成时,所以变成否定句时,直接在have/ has后面加not,原句用的是have,所以havenot可以缩写成haven’t,后面接动词过去分词,故答案为haven’t finished

3句意:——你去过伦敦吗?

根据句意理解及句子结构分析可知,原句是一般疑问句,所以肯定否定回答要用Yes/ No的形式,Yes后面接肯定,No后面接否定,其结构都是“主语+助动词”的形式,现在完成时的助动词是have/ has,可以与not缩写成haven’t/ hasn’t,而回答中句子主语是I,所以这里应该选择用have,故答案为YeshaveNohaven’t

4句意:——汤姆曾经用英语写过电子邮件吗?

根据句意理解及句子结构分析可知,原句是一般疑问句,所以肯定否定回答要用Yes/ No的形式,Yes后面接肯定,No后面接否定,其结构都是“主语+助动词”的形式,现在完成时的助动词是have/ has,可以与not缩写成haven’t/ hasn’t,而句子主语是he,所以这里应该选择has,故答案为YeshasNohasn’t

5句意:他买了五张票。

根据划线部分five可知,这里是对数量的提问,英语中提问数量用how manyhow much,而这里提问的“多少张票”,tickets是复数名词,所以这里应该用how many,后面接一般疑问句,原句中用的是现在完成时,所以疑问句应该用完成时的助动词has开始,故答案为How manyhas

本题句型转换的重点是考查现在完成时的句型转换,包括转换成否定句,疑问句以及肯定否定的回答。重点是要弄清楚现在完成时的结构中have/ has是助动词,所以转换中直接借助have/ has就可以转换,要注意不同的人称用的助动词不一样。比如第三、四两题,都是肯定回答和否定回答,但是第三题的主语是第一人称I,所以用的是have;而第四题的主语是第三人称he,所以用的是has,所以做题要注意区分。
