“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.

D
Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（症状）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提钻）on a building site.
Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（听觉神经）that connect to the brain. If this happens, hearing loss becomes permanent.
【小题1】Which of the following shows that you are suffering hearing loss?
| A．You are interested to listen to others’ talking. |
| B．You have to read others’ expressions to understand them. |
| C．You can only understand others over the phone. |
| D．You always think you hear the ringing of the phone. |
| A．Listen at least an hour every time. |
| B．Turn up the volume to the highest level. |
| C．keep the sound lower than 60% of its highest volume. |
| D．Choose classical, rock or heavy metal music. |
| A．d-a-c-b-e | B．e-c-a-b-d | C．b-c-a-d-e | D．d-e-a-c-b |
| A．music that teenagers like | B．hearing problems caused by the loud world |
| C．ways that teenagers enjoy music | D．dangerous modern lifestyles of teenagers. |

Before going outside in the morning, many of us check a window thermometer(温度
计)for the temperature. This helps us decide what to wear.__【小题1】__. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer t
o see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.
Both systems use the freezing and boiling points of water as their guide.__【小题2】___.
The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.__【小题3】_.
First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.____【小题4】___.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily. ___【小题5】____.
As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
| A．People use thermometers which are made by themselves when travelling around the world. |
| B．We use and depend on thermometers to measure the temperature of many other things in our daily lives. |
| C．Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. |
| D．Now that you know this rule you can make a thermometer of your own that will work. |
r will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.查看答案和解析>>
