1.___(reach) has shown that stress is harmful to people's health.
2.She received a lot of ___(train) before she began to work in the plant.
3.-Jimmy is leaving for a holiday.-Really?where ___ he ___?
A.has,gone B.will,go
答
1.Research 研究
它是不可数名词,所以无复数形式.
2.training 训练/培训
它也是不可数名词,也没有复数形式.
3.B
由问句“is leaving for”可知,Jimmy还未动身度假.此句为现在进行时表示一般将来时.
所以答句也用一般将来时,而不能选A去用现在完成时.
