16.Since many young people have become rich on Taobao.com,I wonder what     is like to run a successful on-line business.( 。
A.thisB.thatC.itD.one

分析 由于許多年輕人在淘寶網(wǎng)上變得很富有了,我想知道運行一個成功的網(wǎng)上業(yè)務是什么樣的.

解答 答案:C.根據(jù)真正主語to run a successful on-line business可見空白處應為形式主語,縱觀選項,唯有it可擔當形式主語,故選C.注意區(qū)分代詞that指代不可數(shù)名詞或the+n;one.泛指,相當于a+n; it 用來指代上文提到的內(nèi)容.

點評 本題考查it 形式主語,結合語義的基礎上便能選出正確答案,同時要注意與其他代詞不要混淆.

1.Eight-year-old Jesse Abrogate was playing in the sea late one evening in July 2001 when a 7-foot bull shark attacked him and tore off his arm.Jesse's uncle jumped into the sea and dragged the boy to shore.The boy was not breathing.His aunt gave him mouth-to-mouth resuscitation (人工呼吸) while his uncle rang the emergency services.Pretty soon,a helicopter arrived and flew the boy to hospital.It was a much quicker journey than the journey by road.
Jesse's uncle,Vance Folsenzier,ran back into to the sea and found the shark that had attacked his nephew.He picked the shark up and threw it onto the beach.A coastguard shot the fish four times and although this did not kill it,the shark's jaws relaxed so that they could open them,and reach down into its stomach,and pull out the boy's arm.
At the Baptist Hospital in Pensacola,Dr Ian Rogers spent eleven hours reattaching Jesse's arm."It was a complicated operation,"he said,"but we were lucky.If the arm hadn't been recovered in time,we wouldn't have been able to do the operation at all.What I mean is that if they hadn't found the shark,well then we wouldn't have had a chance.'
According to local park ranger Jack Tomosvic,shark attacks are not that common."Jesse was just unlucky,"he says,"evening is the shark's feeding time.And Jesse was in area without lifeguards.This would never have happened if he had been in area where swimming is allowed.'
When reporters asked Jesse's uncle how he had had the courage to fight a shark,he replied,"I was mad and you do some strange things when you're mad."
56.What was the boy doing when the accident happened?D
A.Feeding a hungry shark.
B.Jumping into the rough sea.
C.Dragging a boy to the shore.
D.Swimming in a dangerous area.
57.In which way did the boy's uncle help with the operation?A
A.By finding his lost arm.
B.By shooting the fish.
C.By flying him to hospital.
D.By blowing into his mouth.
58.How was his uncle in time of danger?B
A.Careful.B.Brave.C.Optimistic.D.Patient.

Since the story was first printed,it has kept selling up to the present day.It has been translated into over fifty languages and has had several movies based on it.

Nowadays,mobile phones are become more and more popular in the middle school students.In my opinion,we can bring mobile phones to school.As we know,the 21st century is a modern age and full of informations.A mobile phone is one of the quicker tools for us to exchange messages.The mobile phone is a fashionable and useful invention,but we ought to make the best use of it.Suppose there's sudden accident,it is more conveniently for us to dial for help immediately.There're also some games in the mobile phone.We can relax us by playing them when we're tired of our studies.In my opinion,It's not wrong to follow after the fashion,but the most important thing is that to use the mobile phone in a right way.
