Answer 1

第一题选A,put sth into practice,把。。付诸实践
第二题选B，整宾语从句用的是将来时，将要召开的，而且又是被动语态，所以是to be held
第三题可以用排除法，首先排除what ,因为后面有宾语products,再排除where，因为后面有地点状语from our company,然后再AC当中选，我个人觉得应该选A,这个就是凭语感，感觉翻译出来要通顺些
第四题选A，从整个句子来看，应该是用过去完成时，自己理解理解哈
第五题选A，因为一次性买大量的降价的天然气这件事他一直都在做，客观存在的真理还有一直都维持这个状态的之类的用一般现在时
我个人觉得你在3,4,5里面选一题都行

Answer 2

1.A 2.B 3.A 4.C 5.D 给我采纳，谢谢！！！！！！！

Answer 3

1.A 固定搭配put …into practice 把…付之于实践

2.B 从语义中可看出还没有召开，应为将来时，the 29th Olympic Games是被动语态，要用 to be done 句式

3.A 题中的各个成分完整 只能填that，引导宾语从句

4.A 从整个语义看，是过去已完成的事，所以要用过去完成时，只有A时态正确

5.D 注意理解语义，a while back意思是“前一阵子”的意思，所以买大量的降价的天然气这一动作已经完成，所以用完成时。

觉得第3题比较难，第5题只要知道a while back的意思的话就不难判断出！
