　　Most British telephone cards are just plain green, but card collecting is becoming a popular hobby in Britain and collectors even have their own magazine, International Telephone Cards. One reason for their interest is that cards from around the world come in a wide variety of different and often very attractive designs. There are 100, 000 different cards in Japan alone, and there you can put your own design onto a blank card simply by using a photograph or a business card.

　　The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and. now you can buy cards in more than a hundred countries. People usually start collecting cards because they are attractive, small and light , and they do not need much space. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can buy only telephone cards, and some French cards cost up to 4, 000 pounds. The first Japanese card has a value of about 28, 000 pounds. Most people only see cards with prices like these in their collectors magazine.

The blockbuster film Titanic has brought millions of dollars and thousands of people to the theaters and continues to touch people today in their homes. Why is this film so successful? It is a combination of many different things. Among these are many different elements. Looking at some of these elements will show how the director and others involved were able to create an emotionally charged movie that appealed to millions.

The film uses one thematic(主题的) element called - The Truth of Human Nature. The two main characters seem to represent noble people. Most of the other characters in the film are shown as non-tolerant, rude and cold-hearted people. The element of focusing on the two main characters' love and emotion seems symbolic of an ideal state.

There are also social problems addressed. This is done in a few different ways. The most noticeable way is that the lower class people remain locked in the basement as the ship goes down. Throughout Titanic, the lighting is very important. The poor, lower class people are always shown in very warm-coloured light that gives them a sense of life and happiness. On the other hand, the rich, upper class are always shown in a flat light portraying the feeling of hardness and coldness. By using these techniques, they show the issue of class segregation(种族隔离), and they create stereotypes. The main characters are able to break free of these stereotypes and be together. This is the solution to the segregation problem.

As you can see, Titanic took a lot of thinking and preparation to film in a manner that would create emotion and bring to the surface the issues and story of the great ship.

D．emphasize the condition of the poor at that time

3.Why were different colours of light used in the film Titanic? ________

A．They were used to show the difference between the rich and the poor.

B．The director was determined to achieve good visual effect.

C．The social status was represented by the color of light in the past.

D．The use of light was the main technique the director made use of.

4.What can we infer from the passage? _________

A．The segregation problem in the society can be solved by using the light.

Scientists from South Korea are trying to convert（转化）sound waves into electricity. The research could lead to charging a cell phone from a conversation or providing energy to the nation’s electricity system generated（产生）by the noise during rash-hour traffic.

“Just as speakers transform electrical signals into sound, the opposite process —turning sound into a source of electrical power — is possible,” said Young Jun Park and Sang-Woo Kim, the joint authors of a new article in the journal Advanced Materials.

Harvesting energy from phone calls and passing cars is based on materials known as piezoelectrics. When bent, piezoelectric materials turn that mechanical energy into electricity. Lots of materials are piezoelectric: cane sugar, quartz （石英）and even dried bone which could create an electrical charge when stressed. For decades, scientists have pumped electricity into piezoelectric materials for use in environmental sensors, speakers and other devices.

Over the past few years, however, scientists have made dramatic advances in getting electricity out of piezoelectric devices. In an experiment, by using sound waves, which at 100 decibels（分贝）were not quite as loud as a rock concert （a normal conversation is about 60-70 decibels）, the South Korean scientists produced a mild electrical current of about 50 millivolts（毫伏）. The average cell phone requires a few volts to function, several times the power this technology can currently produce.

“But the real question is whether there is enough surrounding noise to act as a power source as for a cell phone,” said McAlpine, a leading scientist. A consumer probably wouldn’t want to attend a rock concert or stand next to a passing train to charge his cell phone. The South Korean scientists agree but they expect to get a higher power output as they continue their work.

1.According to the two South Korean scientists, ________.

A．sound waves can travel faster than electricity

B．new materials can send cell phone signals better

C．using cell phones adds to heavy traffic in rush hour

D．electricity and sound can be transformed into each other

2.We know from the passage that piezoelectric materials ________.

A．can produce electricity when stressed

B．are good at changing electricity into sound

C．can reduce the noise of passing cars

D．have been widely used in phones and cars

3.It can be inferred from the South Korean scientists’ experiment that ________.

A．it is hard to change sound into electricity under current conditions

B．it is impossible to make use of loud sound

C．the technology has a long way to go to have a practical use

D．the technology can power cell phones easily

4.What McAlpine doubts about the technology is ________.

A．the noise pollution                      B．the sound resource

C．the cost of piezoelectrics                 D．the safety of devices

“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.

The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.

Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version（版本）of the software, users can also send a spoken message.

The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.

In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”

The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.

If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.

Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.

Other security software allows users to erase data remotely or lock down the computer.

1.The expression “to give the thief a piece of their mind “can be understood as “_______”

A. to give the thief an alert mind

B. to express the owners’ anger to the thief

C. to remind the thief of this conscience

D. to make the thief give up his mind

2.Different from other security software, Retriever can         .

A. record the stealing process          B. help recognize the lost laptop

C. lock down the computer remotely     D. send a spoken message

3.One function of the program is that it allows the owner to           at a distance.

A. change some access details for switching on the laptop

B. turn on the laptop by using the original password

C. operate the laptop by means of and alternative password

D. erase the information kept in the stolen laptop

4.Which of the following can best summarize the main idea of the passage?

A. With no Retriever, thousands of laptops are stolen every year.

B. A new soft ware provides a means to reduce laptop theft.

C. Retriever has helped to find thieves and lost computers.

D. A new program offers a communication platform with the thief.
