1、-Have you finished your homework yet?
-Not yet,I___to do it just a few minutes ago.
A.get down B.set out C.set about D.set up
（我感觉应该选C,可是答案给的B,为什么啊）
2、A new technique ___out,the yields increased by20％.
A.having working B.having been working
C.has worked D.had been worked
（答案给的B
3、____all the time is the key to____progress in English
A.Practice,making B.To practice,making
C.Practicing,make D.To practice,make
（答案给的B）

首先,第一题中的B答案是set out.而set out to do something的意思是开始做某事.答案不得而知了吧.
第二题中的B答案,用的是现在进行完成时,说明这项新技术从开始到现在还在一直经行着,从后半句可以看到,这个领域已经提高了20%.
第三题中的B答案,第一个空填的是to形式,是因为不定式代表的是一个从句.可以把它写成这样：The key to making progress in English is to practice all the time.这样子看的话,会比较容易得多.而最后那个to是介词,介词后面加的是动名词,这个你应该知道的.
