13.Jack is a good boy,isn't (be) he?

分析 杰克是一个号男孩,不是吗?

解答 答案:isn't.这里是考查反义疑问句,其主要形式:前肯后否,前否后肯.本句中前面的陈述句是肯定句,故后面的疑问句是否定.陈述部分与疑问部分的动词时态和动词性质应保持一致,故前面是is,故后面仍然是is,加上否定not构成isn't,用he代替Jack做主语,故答案是isn't

点评 英语中,反意疑问句是由陈述句和附在其后的附加疑问句组成.其中附加疑问句是对陈述句所说的事实或观点提出疑问,起证实作用,一般用于证实说话者所说的事实或观点.翻译为"是吗"反意疑问句中问句部分的动词与陈述部分的动词在语气上成相反的对应关系,即:肯定+否定?否定+肯定?当陈述句中含有be动词,助动词,或是情态动词时,反问句部分由这些词加上主语人称代词构成,当陈述句中只含有行为动词时,若动词加了s,就用does,若动词为原形,就用do,动词为过去式,则用did.

4.What are you going to do if you are in a burninghouse?How will you escape?Do you know how to save yourself?Please read the following passage.
Escaping a fire is a serious matter.Knowing what to do during a fire can save yourself.It is important to know the ways you can use and to show them to everyone in the family,such as stairways(楼梯) and fire escapes,but not lifts.
From the lower floors of the building,escaping through windows is possible,learn the best way of leaving through windows with the least chance of serious injury(伤害).
The second floor windows are usually not very high from the ground.An average(普通的) person,hanging by the finger-tips will have a drop of about six feet to the ground.It is about the height of an average man.Of course,it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help.Be sure to keep the door closed,or smoke and fire may be drawn into the room.Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(渗入) into the room.
On a second or third floor,the best windows for escaping are those which open onto a roof.From the roof a person can drop to the ground more safely,dropping onto stones might end in injury,bushes and grass can help to break a fall.
