A．If I devotedB．Had I devoted
C．Would I be devotedD．Should I be devoted

分析 假如我以前能夠?qū)⒏嗟木Ψ旁趯W(xué)習(xí)上而不是癡迷于網(wǎng)絡(luò)游戲，我現(xiàn)在就會(huì)坐在舒服的辦公室里了．

解答 答案：B．
本句是混合虛擬語氣．主句與現(xiàn)在事實(shí)是相反，用would+動(dòng)詞原形的形式；而從句與過去事實(shí)是相反，故從句中用過去完成時(shí)，因?yàn)閺木渲泻衕ad，故可以將if去掉，把had提到主語I前面來．因此選B．

點(diǎn)評 考查時(shí)間錯(cuò)綜的虛擬條件句．有時(shí)if從句和主句所表示的假想情況時(shí)間不一致，如從句與現(xiàn)在事實(shí)相反，而主句表示與過去事實(shí)相反，那么句子兩部分的動(dòng)詞形式應(yīng)作相應(yīng)的調(diào)整．如：If I had asked her for advice yesterday，I should know what to do now．

A．A sense of humour is not an inborn ability．
B．A sense of humour can be developed in our life．
C．A sense of humour helps us from several aspects．
D．A sense of humour means more than telling jokes．
E．A sense of humour can be expressed in many ways．
F．A sense of humour helps people to better enjoy life．
61．A sense of humour helps us from several aspects．
As awareness of the cenefits of humour increases，most of us want to get all the langhs we can．It seems that almost every day there is another new discovery about the power of humour to help us physically，mentally，cmotionally，and sp[iritually．Every system of the body responds to langhter in some important or positive way．
62．A sense of humour is not an inborn ability．
Many pcople mistakenly believe that we are born with a sense of humour．They think that when it comes to a sense of humour．"either you have got it or you don't．"This is
false!What is true，however，is that the ability to laugh and smile is actually something we are born with．For example，we laugh when we are tickled under the arm，even without thinking about how to react．
63．A sense of humour can be developed in our life．
The parts of the brain and central nervous system that control laughing and smiling are mature at birth in human infants，but that is not the same thing as having a sense of humour．（After all，when a baby laughs in his small bed we don't rush over and say，"That kid has a great sense of humour!"） Your sense of humour is something you can develop over a lifetime．Don't be nervous before others and try to laugh at yourself-then you will make them laugh too．
64．A sense of humou means more than telling jokes．
Humour includes a lot more than laughing and joke telling．Many people worry needlessly that they do not have a good sense of humour because they are not good joke tellers．More than jokes，a sense of humour requires being willing and able to see the funny side of life's situations as they happen．In fact，one of the best definitions（定義）of a sense of humour is"the ability to see the nonserious element in a situation．"
65．A sense of humour helps people to better enjoy life．
There may be a thousand different ways to express your sense of humour，but joke telling is only one of those ways．As more is discovered about how humour benefits our life，more people will be able to see and enjoy the humour when they are in a difficult situation．Life depends on air，food and water，but it is made easier to live with a good sense of humour．

Researchers have created a backpack that has a computer and medicines in it that can help even untrained soldiers save the lives of wounded troops. Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends.

Doctors and engineers have developed what they call an “intelligent backpack”.It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to give to injured troops.

About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The U. S. Department of Defense has given money to the project.

Ron Poropatich leads the project. He is a retired army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a person^ heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung.

The intelligent backpack's computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to use to save the soldier’s life.

Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield.So,Dr. Poropatich says, the researchers hope to create a backpack that will have devices .that can keep a .soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing animals in about three years.

1.What can we learn from the first paragraph?

A. The backpack can play a big part in the battlefield.

B. Most of the soldiers can’t use the backpack correctly.

C. Soldiers should have taken medical training.

D. War or battle has brought harm to the world.

2.How many kinds of items are mentioned in the backpack?

A. 4. B. 5. C. 3. D. 2.

3.What can we know according to Ron Poropatich?

A. The project got support from the whole world.

B. The robotic instruments can monitor lungs.

C. The injurer's heart disease can he cured.

D. The devices can adjust soldiers’ blood pressure.

4.Which of the following is the best title for the passage?

A. Researchers and Their Wonderful Discovery

B. Medical Care Tested on the Wounded Soldiers

C. Emergency Medical Care in a Backpack
