    ¡¡¡¡At the moment£¬it may be difficult to imagine£¬but many people believe that£¬by the year 2100£¬we will live on the planet(ÐÐÐÇ) Mars.Our own planet£¬Earth£¬is becoming more and more crowded and polluted.We should build a better world on Mars.

    ¡¡¡¡First of all£¬transport should be better than they are today.Now it is difficult for spacecraft(ÓîÖæ·É´¬) to carry too large number of people to Mars—it takes months.By 2100£¬travel to Mars will take a very short time in space shuttles that travel at half the speed(ËÙ¶È) of light.

    ¡¡¡¡Humans need water£¬air and food to survive.Scientists should be able to develop the plants that can grow on Mars.These plants can provide the air and food that we need.However£¬the scientists are not sure whether these plants can provide water.

    ¡¡¡¡Gravity(ÖØÁ¦) will be the problem for the early settlers on Mars.The gravity on Mars will be about only three-eighth of the gravity on Earth.It is very dangerous for us because we can easily jump too high and float(Ư¸¡) away into space.To prevent this£¬we have to wear special boots to make ourselves heavier.These boots will probably very popular and there will be many different designs for settlers to choose from.

    ¡¡¡¡Life on Mars will be better than life on Earth in many ways.We will have more space.Living in a dome with 10 bedrooms is highly possible.Many people thought that robots will do most of our work and we will have more time for our

    hobbies.There will be no schools on Mars.Students will have a computer at home connecting to the inter-planet computer network.They can study£¬do homework and take exams in online schools.

    ¡¡¡¡However£¬in some ways£¬life on Mars may be worse than life on Earth.For example£¬food will be not the same as they are today£¬it may be in the form of pills(ҩƬ).

    Stop! Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud and unwanted sound.
    Noise can be caused by many kinds of machines, such as motorcycles, jet planes, tractors and so on. And, to some people, rock bands are also noise.
    What happened to people who live near noisy machines or use them over a period of time? Doctors find that these people have trouble in sleeping, But, most important, constant loud noise can cause a loss of hearing.
    Scientists use a unit of measure called a decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the greatest hearing loss.
    ¡¾Ð¡Ìâ1¡¿ From the article we know noise is ___________.
    A£®wanted soundB£®loud and unwanted sound
    C£® all sounds that you can hearD£®comfortable sound
    ¡¾Ð¡Ìâ2¡¿  A ¡°decibel¡± is a _________
    A£®unit that measures soundB£®kind of noise
    C£®machine that makes very loud noiseD£®person who hates noise
    ¡¾Ð¡Ìâ3¡¿According to the passage, loud noise can ________.
    A£®help people sleep betterB£®stop machine

    A£®noise pollution can be a serious problem
    B£®rock bands are noisy
    C£®noise can cause people to be mad
    D£®some people hate noise deeply
