You cook your meals and it is energy that gives you heat to boil rice.
The problem is that the demand for energy is rising and that the price of energy is getting higher and higher. The supply of energy on earth is limited. It cannot provide us all forever. The shortage of energy in the future is inevitable. Therefor, saving energy is a must if we want to contine to live in a cafe and sound world.

Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but shouldalso try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

1. Pollution is caused from the following sources except .

A. water in rivers B. water from households

C.wastes D. house chemicals

2. Recycling can help us .

A. never cut down trees B. produce more paper products

C.place garbage bins easily D. use products again and again

3. In order to save water, we can do all of the following things except .

4. Recycling helps to reduce waste because .

Read the passage and do the tasks that follow:

AMAZING NEW INVENTIONS

Every year, more and more amazing things are invented. Here are three of our favourites for this year.

A. Fukuda’s Automatic Door

Can you imagine a door that fits around your body as you walk through it? Fukuda’s Automatic Door was designed in Japan by an inventor named Rikiya Fukuda. It automatically indentifies movement and only opens just enough to match the shape of the person or object coming through. So, what are the advantages? It saves energy by helping to keep the same temperature in a room. It can also prevent dirt and other materials from being carried inside. As well as people, the Automatic Door works for small objects, like packages delivered to a post office, or for larger things, such as a car coming through a garage door.

B. The Hand Roll Piano

Traveling musicians will be happy with this invention. The Hand Roll Piano was invented by the Japanese company Yamano Music. What makes it different is that it can be rolled up like a blanket. This makes it easier to carry and easier to store. The keyboard is 100 cm long but weighs just 1 kg. It has 61 very thin keys and is made of rubber. It’s convenient to carry, but it’s also a great instrument. The piano can be played for up to 15 hours on standard batteries. It has more than 100 sounds and its own speaker.

C. The LifeStraw

Today, more than one billion people in the world do not have safe water. However, it’s been discovered that for the price of a cup of coffee, a life can be saved. The LifeStraw, which costs just $3, is a device for purifying water. It is able to turn dirty water into drinking water. The drinking straw was designed by the Swiss-based company Vestergaard Frandsen. It uses seven types of filter to make water clean enough to drink. It can prevent illnesses and it can also create safe drinking water for victims of hurricanes, earthquakes or other disasters.

Task 1. Choose the best description (from a - d) for each paragraph. There’s one extra description you do not need to use. Write your answers in the space provided.

a. It’s an invention that saves lives.

b. It helps you to do housework.

c. It’s a device that knows when you are coming.

d. It makes entertaining easier.

Read the following passage. Find the five mistakes, underline the mistakes and write the correct words.

Children love to play computer games. Some people say that many of them are addicted to games. If you become addicting, all you can think about is computer games and you cannot spend a day without playing. Of course, playing games on the computer is the great way to spending time and have fun. But there are also bad sides to it as well.

First of all, you do not get enough exercise because you do not have to move your body much when play games. Second, your eyesight becomes badly because your eyes are fixed on the computer screen for to long. This is why not it is not hard to find children wearing glasses around theses days. Third you do not get to spend much time with your family because are spending all time of your time in front of the computer.

Playing computer games is not such as bad thing. But too much playing can cause problems. How much hours do you spend in front of the computer? Why not take this opportunity to cut down on the computer games?

Noise is constant and loud sound. To measure the loudness, or volume of sounds, people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or a motorcycle can result in permanent hearing loss after eight hours? The sounds of a concert are even more serious. They can reach as high as 130 decibels and may cause immediate and permanent hearing loss. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music through headphones, and other people can hear it. it means the music is too loud and unsafe. If there seems to be a ringing or buzzing in your ears, it means the noise is affecting you and damaging your hearing- Wearing earplugs when you go to concerts or other loud events, and listening to music through headphones or headsets at safe levels can help you reduce the effects of noise pollution.

1. What do people use to measure the loundness or volume of sounds ?

.............................................................................................................................................

2. Does the noise from a vacuum cleaner result in pernament hearing loss after eight hours ?

..............................................................................................................................................

3. What can noise pollution also lead to ?

4. Is the music safe when you listen to it through headphones , and other people can hear it as well ?
