在after引導的時間狀語從句中，主句用一般將來時，從句用一般現(xiàn)在時表示將來；he為第三人稱單數(shù)，故選A。典型例題

Mrs.Blackwillcometohelpusifshe_______toobusytomorrow.A.isB.willbeC.won’tD.isn’t解析：“如果布萊克夫人明天不是很忙的話，她會來幫助我們”。在if引導的條件狀語從句中，若主句用一般將來時，從句要用一般現(xiàn)在時表示將來。根據(jù)題意可知選D。【解析】考查if引導的條件狀語從句。當主句是一般將來時，if引導的條件狀語從句應該用一般現(xiàn)在時。句意為“如果這個星期天不下雨的話，我們就去野餐”。故選B?！猈e'llgoforapicnicifit_______thisSunday.—Wishyoualovelyweekend.A.rainB.doesn'trainC.won'trainIwillsendyouane-mailassoonasI______inCanada.

A.arriveB.arrivedC.amarrivingD.willarrive【解析】本題考查狀語從句的時態(tài)。當主句是將來時態(tài)時，狀語從句用一般時態(tài)來代替將來時，所以選擇答案A。Ifthere______nobuyingandsellingofanimals,there______nokillinginnature.A.is;willbe

B.willbe;willbe

C.is;is

D.willbe;is【解析】本題考查if引導的狀語從句的時態(tài)。if意為“如果”，引導條件狀語從句，主將從現(xiàn)。故選A。（2016?安徽）Ourworldwillgetbetter
