A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃惊的) ways of cheating every day; some claim that certain accounts of cheating can be justified, but overall it can always be prevented.
Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.
There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the student could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students refrain(制止) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.
It may be difficult to accomplish, but cheating can be prevented. Teachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling(驱逐) a student, which will most likely hindertheir plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way to avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.
There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.

Few people would question the value of taking part in sports for young people．With proper training，supervision，protective equipment and techniques，and an proper emphasis on winning，sports can develop a healthy body and spirit and a life-long interest in being active and fit .Without such measures，childhood sports can lead to injuries and even paralysis or death．

Even in the best conditions，no activity can be risk—free．But most serious hazards are preventable．Cyclists and football players can reduce their risks by wearing helmets；hockey players by wearing masks；basketball and tennis players by wearing eye guards；baseball players by wearing batting helmets．

Besides，risks to individual players can often be found，and thus prevented，through a properly performed medical exam before a child plays．For accidents that may not be preventable，having an emergency plan and first-aid equipment，and someone trained to use the equipment，can be lifesaving．

Still，each year，according to the American College of Sports Medicine，more than 775,000 children under 14 are treated in emergency rooms for sports injuries，nearly half of them preventable．An estimated 300,000 athletes experience exercise—related head illnesses each year，and almost all of them should have been avoided．

Further，from half to three—fourths of sports-related concussions（脑震荡） are never even diagnosed；the injured are often sent back in to play too soon and put at risk of another more serious brain—damaging concussion．To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www.SportsSafety.org.

68．Which of the following is true according to the passage?

A．All the accidents can be prevented．B．All the accidents cannot be prevented．

C．Lives can be saved so long as there is proper equipment．

D．Lives cannot be saved even if there is proper equipment．

69．What does the underlined word “hazards”(in paragraph 2)mean?

A．mistakes          B．diseases           C．dangers            D．situations

70．It is implied in the passage that         ．

A．prevention of injuries is not paid enough attention to

B．children under 14 are more easily hurt in sports

C．most head illnesses are related with exercise

D．none of the head illnesses should have happened

71．What can coaches mainly learn from the online safety course?

A．How to cure brain-damaging concussion．

B．How to diagnose brain-damaging concussion．

C．How to predict the possibility of brain damage．

D．How to deal with the injured properly．

You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.

  When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.

  In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the back of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.

  Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can resist massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

What does the author say about the black box?

A. It ensures the normal functioning of an airplane.

B. The idea for its design comes from a comic book.

C. Its ability to resist disasters is incredible.

D. It is an indispensable device on an airplane.

What information could be found from the black box on the Yemeni airliner?

A. Data for analyzing the cause of the crash.

B. The total number of passengers on board.

C. The scene of the crash and extent of the damage.

D. Homing signals sent by the pilot before the crash.

Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. Too much space was needed for its installation.

C. The early models often got damaged in the crash.

D. The early models didn't provide the needed data.

Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?

A. To distinguish them from the colour of the plane.

B. To caution people to handle them with care.

C. To make them easily identifiable.

D. To conform to international standards.

What do we know about the black boxes from Air France Flight 447?

A. There is still a good chance of their being recovered.

B. There is an urgent need for them to be reconstructed.

C. They have stopped sending homing signals.

D. They were destroyed somewhere near Brazil.
