课时作业(七)
Ⅰ.语法运用
1.But the firefighters failed to save the dog's owner because if they __had_walked__(walk) onto the mud,they would have sunk,too.
解析:句意为:但是消防队员未能救出狗的主人,因为,如果他们踏上淤泥的话,他们也会沉下去。此处是if引导的非真实条件句,应用虚拟语气,与过去的事实相反,所以用过去完成时态,故填had walked。
2.—Cathy burst into tears at the news that she was turned down by the company,but I meant no harm.
—I would rather you __hadn't_told__ (tell) her about it.
解析:句意为:——凯茜听到她被那家公司拒绝的消息后,放声大哭,但是我并没有恶意。——我宁愿你没有告诉她这件事情。根据句意可知,此处表示“宁愿没有……”,would rather后引导的宾语从句为虚拟语气,根据上句得知,此处表示对过去的虚拟,应用过去完成时,故填hadn't told。
3.If I __were__(be) at home in Cambodia,I would have to go outdoors.
解析:句意为:如果我在柬埔寨的家里,我就不得不出门。根据主句的谓语would have to go可知此处是if引导的非真实条件句,与现在的事实相反,从句用一般过去时态,be动词的过去式用were,故填were。
4.I am sorry I am very busy now.If I __had__(have) time,I would certainly go to the movies with you.
解析:句意为:对不起,我现在太忙了。如果有时间我肯定和你一块儿去看电影。本句中If引导的从句表示对现在的情况进行假设,主句用“would+动词原形”,从句用一般过去时,故填had。
5.According to the local law,no one __shall__ enter the building site without permission.
解析:句意为:根据当地法律,未经许可任何人不得进入这个建筑工地。根据law可知,此处应填shall,shall用于法律、规定等,意为“必须”。
6.Jane could __have_come__ (come) to the party,but she could not find the exact time.
解析:句意为:简本来能来参加聚会,但是她没能找到确切的时间。根据but分句中的could not find可知,此处指与过去事实相反的假设。could have done表示“本可以做某事,但实际没做”。故填have come。
7.He was greatly shocked at the man's taking office.Never did he expect that the voters __should__ be so unreasonable.
解析:句意为:他对那个人的就职大为震惊。他从未料到选民竟然如此不理智。根据前面的greatly shocked可知,他感到出乎意料,故填should,表示惊讶和意外,意为“竟然”。
8.It's time that we __did/should_do__ (do) something quickly.
解析:It's time that...意为“该做……的时候了”,从句常用虚拟语气,即从句谓语动词用动词的过去式或should do,故填did/ should do。
9.If teens see that their physical condition is causing them to perform badly,they may __be_motivated__ (motivate) to do other activities to get healthy.
解析:句意为:如果青少年看到他们的身体素质导致自身表现不佳,或许会激励他们去做其他的活动,以保持身体健康。情态动词may后用动词原形,且they和motivate之间是被动关系,故应用被动语态。故填be motivated。
