Japanese police said. In what media are calling the “Hi, it’s me” trick, victims(受害者)receive calls from cheats who call themselves only as “me” and say they are in great need of money to cover anything from an uninsured(未上保险的)traffic accident to an unexpected trouble. Victims think the person on the phone must be a close relative and often agree to send the money to bank account specified by the cheat straight away. There have been 3,807 reported cases till November 2003, with victims paying out a total of almost 2.3 billion yen ($ 21.1 million), according to the police figures. Many of the victims were women over 40, according to domestic(国内的)newspaper. Police said they were advising that people check the identity of people asking for money on the telephone.

Hey, I’m in TroubleB. Hey, Help meC. Hey, It’s me! Send MoneyD. Hey, I Need Money BadlyCLook closely at the palms of your hands and fingertips. See all the tiny lines? Each of us is born with a unique set of prints, but it may surprise you to learn why we have them. Palm-lines are not for fortune-tellers to figure out how long we will live, nor are fingerprints there to make a policeman’s job easier. In fact, the lines and loops that decorate o ur hands and feet are an evolutionary gift from nature, and they serve two important functions.Our prints are made of raised and lowered skin. The raised areas function somewhat like the tread(纹)of car tires or the rubber soles of our running shoes. When we touch something that is wet, water moves from these “hills” into the “valleys’, which means some surfaces on our skin remain relatively dry. This is useful, for it allows us to better grip the things we want to hold.Our prints help us hold on, but they also have a secondary function: protection. The raised areas serve as buffers(缓冲物)between our skin and an object, keeping us from getting hurt every time we grip the hard surface of a bottle or a baseball bat. This is the same reason why, when we walk too far or wear uncomfortable shoes, we get blisters on the soft skin of our ankles, but never on our heels, like our palms and fingers, have prints to protect them.It is the random(任意的)flow of fluids inside our mothers wombs that causes these useful patterns to form on the surface of our hands and feet. Because they are formed randomly, each person’s prints are unique, which makes prints accidentally useful as a means of distinguishing between people. Even identical twins have different prints, which means that no mistake can be made in determining who did a crime, provided fingerprints or toe prints were left at the scene.44.Where can’t you find the tiny lines?A. Palms.B. Fingerprints.C. Heels.D. Ankles.45.Which of the following is NOT mentioned in the passage?A.The tiny lines are the results of evolution.B.From one’s fingerpr ints, we can guess his character.C.Different people have different prints in their fingertips.D.The prints play an important role in our life.46.Which of the following statements is true according to the passage?A.Fingertips can help us hold on to things better.B.There are no prints on our heels.C.The prints can make our palm dry.D.Prints can protect our skin from getting hurt.47.Which is the best title for this passage?A. Why Do We Have PrintsB. The Formation of PrintsC. The Importance of PrintsD. The Function of Prints四、单词填空(16%)48.Only parents can make s_________ for their children, especially in time of danger.49.I couldn’t r_________ taking aim at the wild geese as they flew over.50.
