The following are the results of the tests done by “Family and Home Magazine” on some Pocket Tape-Recorders on the market now.
Pearlcorder S702 $64
This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn’t turn off automatically.
Tape length: 30minutes per side. Weight: 240g.
Sony M9 $49.95
Small and very good looking, Sony’s latest offering scored most for its appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. It doesn’t switch off automatically, but a red light shows if the machine is still running.
Tape length: 60minutes per side. Weight: 195g.
Sony M400 $115
Lots of little control buttons that make a noise are difficult to use. Recording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful.
Tape length: 60 minutes per side. Weight: 230g.
Imperial OEM MC7 $ 29.95
Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own-make of cassette. No light to show it is on; no fast-forward button and the record button makes a loud noise.
Tape length: 30 minutes per side. Weight: 285g.
Philips 585 $80
Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light.
Tape length: 15 minutes per side. Weight: 220g.
46. The machine that produces the best recording with the least unwanted noise is __.
A. Pearlcorder S 702 B. Sony M9
C. Sony M400 D. Imperial OEM MC7
47. If you want a machine which turns off automatically and weighs very little you should choose _____.
A. Pearlcorder S 702 B. Sony M9 C. Sony M400 D. Philips 585
48. Which of the following allows you to record longest but costs you least?
A. Philips 585 B. Imperial OEM MC7 C. Sony M400 D. Sony M9

The computer is fast, and never makes a mistake, while people are too slow, and full of mistakes sometimes. That’s what people often say when they talk about computers. For over a quarter of a century, scientists have been making better and better computers. Now a computer can do a lot of everyday jobs wonderfully. It is widely used in factories, hospitals, post office and airports. A computer can report, decide and control in almost every field. Many computer scientists are now thinking of making the computer “think” like a man. With the help of a person, a computer can draw pictures, write music, talk with people, play chess, recognize voice, translate languages and so on. Perhaps computer will one day really think and feel. Do you think the people will be afraid when they find that the computer too clever to listen to and serve the people?

Earth is the third planet from the sun. It is one of the four inner planets. The other three inner planets are Mercury, Venus, and Mars. The inner planets are also called the rocky planets, because th
ey are made of rocks.Earth is often called the “Water Planet”, because it is the only planet in our solar system which has liquid water on its surface. About 70% of the surface of Earth is covered by water! The other part of Earth is made up of continents and islands which have different landforms on them. Examples of landforms are mountains and plains. Plants and animals can live on Earth, because it has so much water.
Earth spins very quickly compared to other planets. It only takes Earth 24 hours to spin around its axis one time. One Earth day is 24 hours long! Earth orbits the sun in 365 days! This makes one Earth year 365 days long!
Earth is the only planet in our solar system where humans, other animals, and plants can live. There is plenty of water to drink or to live in. Water is present on Earth in its big oceans and in the air! Clouds are made of water vapor. The atmosphere has a lot of oxygen in it for animals to breathe, but the rest of our “air” is made up of water vapor, nitrogen, carbon dioxide, and other gases. The air is perfect for plants to grow. Earth temperature is not the same in all places, but the temperature is just right for plants, animals, and humans in most places on Earth.
Like the other inner planets, Earth has volcanoes. Volcanoes on Earth are different from those on other planets, because they still erupt. Scientists think that there may be active volcanoes on other planets and moons in our solar system, but they are still studying this.
Earth has one planet which we call the Moon. The surface of the Moon has many craters on it These were caused when meteorites hit it. It has many volcanoes on it which do not erupt anymore. We can see the moon at night without using a telescope. It is the closest space object to our planet ,Earth.
68.Earth is called the Water Planet,______.
A. because animals need water B. the water makes it look blue from space
C. it has liquid water on its surface D. Earth is the third planet from the sun
69. It takes Earth ______to orbit the sun in one year.
A.24 hours B.24 days C.365 days D.360 days
70. Life exists on Earth,______.
A. because the water, air, and temperature are just right
B. there is water vapor in clouds
C. Earth is the planet closest to the sun
D. earth has volcanoes
71.The craters on the moon were caused by______.
A. meteorites hitting its surface B. active volcanoes
C. volcanoes which do not erupt anymore D. some reasons that are not mentioned

Geniuses amaze us, impress us and make us all a little jealous．How do they differ from the average person? Scientists are working hard to figure out that answer．Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old, he began to play the piano．After a year, he started learning pieces by Beethoven．Now he’s a world-famous concert pianist at age eight．He learns newer and more difficult pieces with ease and can identify any note he hears．He seems to be specially designed for music．In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits.
Genius didn’t come naturally to Tommy McHugh．His came only after he nearly died from bleeding in his brain．After recovering, McHugh’s head was filled with new thoughts and pictures．So, he began to express them in the form of poetry and art．Now, he’s a seemingly unstoppable creative machine．Sufferers of autism and brain injury have shown that great mental ability can sometimes come from damage or disease．Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses? Susan Polger has shown no signs of extraordinary intelligence．Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately．As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards．Make Me a Genius examines what it takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy, we’d all be one．Yet, there is much more to super intelligence than simply being born lucky．Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.

How will the earthquake affect the teenagers mentally?
They’ll have feelings of fear, anger and feel they are not safe. They will find it hard to focus. They will tend to cry and shout and tremble. And they might be afraid to be alone.
What will happen if they are not helped?
The teenagers will find it hard to live in a balanced way. If things get worse they might not be able to focus on their studies. They might give up on life.
How can we help them overcome these problems?
The first thing is to build up trust with them. Show your sympathy and sadness, and be their friend. Then you have to give them a sense of safety. Tell them that there’s a solution to every problem. Thirdly, try to satisfy their psychological needs. Be a good listener if he or she needs to talk.
Some of us were not directly affected by the quake but have seen images on TV and feel scared. What should we do?

Computer mouse is no longer so strong. A Canadian engineer has invented a system that enables a computer user to push a cursor（光标）across a screen simply by moving his or her nose .He calls his nose-driven mouse a mouse.
The inventor ,Dmity Gorodnichy ,came up with the idea for the mouse while building computer software that would help astronauts operate the Canadarm—a long robotic arm on the U.S. space shuttle .His system employs a web-camera that recognizes a computer user’s nose from 25 pixels ,or points of light. Dmity chose the nose because its position remains relatively constant no matter which way the head moves .The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the screen.
The mouse keeps track of the eyes too. Two blinks（眨眼）are a “double click,” which turns the mouse on or off.
The mouse has received mixed comments from those who hold opposite opinions. One called it “a pointless waste of technology” . Another predicted that the nouse will fail to catch on because it makes users “look silly.” Dmity has already adapted the nouse for NousePong, a video game ,and NousePaint ,a drawing program.
He also predicts that the mouse will attract the people who have suffered from specific disease-pain ,senselessness ,or trembling in the hand caused by the frequent repetition of movements of the wrist and fingers ,such as typing at a computer keyboard .His next plan is to adapt the nouse for use by paralyzed（瘫痪）patients in hospitals .With two blinks of the eyes ,patients could double-click for help.
72．The best title for this passage is probably .
A．Mouse Driven by Nose
B．Cursor Moved Without fingers
C.New Computer System for Astronauts
D．New Type of Mouse for Patients
73．The nouse is a system working by means of .
A．keeping track of the points of light
B．moving one’s nose or blinking
C.moving cursor across the screen
D．matching the user’s nose with eyes
74．The underlined phrase “catch on” means “ ”.
A．become popular B．be used C.get improved D．be made
75．Dmity predicts that the nouse will be more used to help .
A．those who have eye trouble
B．develop a video game and drawing program
C.those traveling in space
D．the disabled with the hand and paralyzed patients
