49 in my tracks .After a long moment ,I began to raise my net ,little by little , 50 beating fast .I could scarcely believe my eyes . 51 I reached in and grabbed it ,with every intention of moving it into the killing jar .But my hand 52 as I reached for the jar. There was the brilliant bloom of orange on the tips of its glowing white wings, and I could feel the creature’s 53 between my fingers.

Many people think a telephone is essential .But I think it is a pest and a time waster .Very often you find it impossible to escape from some idle or curious chatter―box ,or from somebody who wants something for nothing .If you have a telephone in your own house ,you will admit that it tends to ring when you are asleep ,or in the middle of a meal or a conversation, or when you are just going out ,or when you are taking your bath. Are you strong ?minded enough to ignore it , to say to yourself, “Ah ,well ,it will all be the same in a hundred years’ time” You are not .You think there may be some important news or messages for you .I can assure you that if a message is really important it will reach you sooner or later .Have you never rushed dripping from the bath ,or chewing from the table, or dazed from the bed ,only to be told that you are a wrong number?
But you will say ,you need not have your name printed in the telephone directory ,and you can have a telephone which is only usable for outgoing calls .Besides ,you will say, isn’t it important to have a telephone in case of emergency―illness ,an accident ,or fire? Of course ,you are right ,but here in a thickly populated country like England one is seldom far from a telephone in case of dreadful necessity.
I think perhaps I had better try to justify myself by trying to prove that what I like is good .I admit that in different circumstances―if I were a tycoon (business VIP) ,for instance ,or bed ?ridden I might find a telephone essential . But then if I were a taxi―driver I should find a car essential.
Let me put it another way: there are two things for which the English seem to show particular talent; one is mechanical invention, the other is literature .My own business happens to be with the use of words but I see I must now stop using them .For I have just been handed a slip of paper to say that somebody is waiting to speak to me on the telephone .I think I had better answer it .After all ,one never knows , it may be something important.
59.The passage is mainly discussing .
A.that we should be strong enough to ignore a phone call
B.that important message will reach you sooner or later
C.whether it’s necessary to answer all phone calls
D.whether it is necessary to have a telephone
60.Judging from the passage ,who is strong ?minded enough to ignore a phone call?
A.The author. B.A tycoon.
C.A taxi―driver. D.Hardly anyone.
61.According to the passage ,the author .
A.thinks the telephone should go out of our life
B.likes to be different from other people
C.thinks the telephone is annoying
D.speaks favourably of a telephone
62.In the author’s opinion ,which of the following is NOT true ?
A.Nearly everyone has been told a wrong number.
B.It’s necessary for everyone to have a telephone.
C.He himself can not decide whether to answer a call.
D.A telephone directory may bring in unexpected calls.
Normally a student must attend a certain number of courses in order to graduate, and each course that he attends gives him a credit that he may count towards a degree .In many American universities the total work for a degree consists of thirty―six courses each lasting for one semester .A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible for a student to move between one university and another during his degree course ,though this is not in fact done as a regular practice.
For every course that he follows a student is given a grade ,which is recorded ,and the record is available for the student to show to prospective employers .All this imposes a constant pressure and strain of work ,but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm .Students who advise the academic authorities usually perform the effective work of maintaining discipline .Any student ,who is thought to have broken the rules ,for example by cheating ,has to appear before a student court .With the enormous numbers of students ,the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.
63.Normally a student would at least attend classes each week.
A.12 B.15 C.20 D.36
64.According to the first paragraph an American student is allowed .
A.to live in a different university
B.to live at home and drive to class
C.to get two degrees from two different universities
D.to take a particular course in a different university
65.American university students are usually under pressure of work because .
A.their academic performance will affect their careers
B.they want to run for positions of academic authority
C.they have to observe university discipline
D.they are heavily involved in student affairs
66.The student organizations seem to be effective in .
A.dealing with the academic affairs of the university

The newly invented digital camera is fascinating; you can take pictures without film. You can transfer and exhibit your picture globally in a few seconds through the Internet .The image stored in a hard drive will never wear out like the traditional photos .Digital cameras also satisfy the impatient photographer by allowing them to view their masterpiece in real time.
Unlike the images of traditional cameras formed by chemical reaction ,the digital camera works as an image digitizer itself .It’s made of CCD(charge ?coupled device ), a small grid of tiny light ?sensitive cells .When struck by light ,each cell sends out an electrical signal whose waveform characteristics vary depending on the intensity (强度)of light .The signal from each cell is changed into a digital value and stored in the camera’s memory or on an electronic storage medium. A “picture” is reduced to a very long list of numbers waiting to be converted back into visual form. Processed through a computer ,each value becomes a pixel; pixels are reassembled in the original grid pattern and displayed or printed.
The image resolution(分辨率)of a digital camera depends on the CCD. More cells on the CCD mean more pixels on the image ,which gives greater detail and higher image resolution .The early digital camera had resolution only up to 400 pixels per image ,cost several thousand dollars ,and was mainly for business use .Now there are more choices for consumers in different price ranges . The variety of digital camera has amazed first adapters to buy the products.
The digital camera technology is moving very fast .A few months ago ;most of the digital cameras were equipped with focus lenses ,but now most new models are equipped with auto focus lenses at reasonable prices .With all these inventions and technology advancements ,the future of digital camera is bright ,and digital cameras may eventually replace traditional cameras.

People say teenagers are no good. They make too much noise in shopping malls; they drive recklessly up and down America’s main streets; they carry chips on their shoulders as big as the Sears Tower. And at least some of the time those things are true. But we shouldn’t forget that there are hard moments in the life of a teenager too.
I watched such a moment not long ago at a woman’s funeral(葬礼). I didn’t expect the event to affect me. Through much of the ceremony, in fact, I remained unmoved.
Then her teenage grandson stepped forward. With his very first deep breath, every heart in that church was achingly reminded of something we had all forgotten. Softly he began: “I want to share a few values that Nana taught me. She never failed to see light in any situation. When our family dog would literally attact her, what would Nana say? ‘Oh, what beautiful markings that dog has.’ That was Nana.
“She was a strong woman who often lived in the shadow of my grandpa, who was a successful businessman in this city. But she was the one behind the scenes who provided the strength and support for Grandpa’s career,” he said, with a voice now trembling. “That was Nana’s way.”
Through a muffled sob, he continued. “Whenever she did anything worth recognition, you’d have to hear about it from a different source, because she was never one to brag.”
Finally, in a voice breaking free of sorrow, he looked up and said, “Nana taught me courage. She put up an incredible fight to the end, when she died peacefully, which is how she lived her life. That was Nana’s way, and I hope I can carry on in the same manner.”
There are no hearts as sensitive as those of teenagers, because everything is happening to them for the first time. The trouble with teenagers is that they haven’t learned to be controlled.
When that boy rose to speak about the woman who surely had been his truest ally and dearest friend, his honest voice dragged each of us out into the open where we could no longer hide in the calm ritual. He exposed us to the truth about this very real woman who believed in a boy who probably tried the patience of many adults. He reminded us that his grandmother was more than another dot on the chart of life and death.
All over again we felt those powerful losses crisscrossing our own hearts, and we knew that when you say good-bye to a beloved grandparent, you say good-bye to something happy, something young in yourself. And that something never really returns, and the pain never really goes away.
