Answer 1

【答案】
（1）has；never；been
（2）haven't；planted；any
（3）Has；learned
（4）has；lived；for
（5）Yes；have；No；haven't
【解析】（1）never 和 before是现在完成时的标志，故改为现在完成时的句子，填：has never been 。
（2）本句是现在完成时，否定句需要在助动词have后面加not构成，some 在否定句中改为any，故填：haven't planted any。
（3）本句是现在完成时，一般疑问句需要将助动词has 提到句首，故填：Has learned。
（4）原句意思是“艾米五年以前就开始住在中国了”，可以用延续性动词改写句子，表达“艾米已经在中国住了五年了”之意，故填：has lived for。
（5）现在完成时肯定回答用 Yes, they have；否定回答用 No, they haven't.
