In our daily life, we can live a low-carbon(低碳) life by paying attention to how we dress, eat and live.

Wear“out”

I prefer simple clothing and buy new clothes only when I really need them. I don’t mind using the same clothes for over 10 years. My family members never throw their clothes away. Instead, we give them to others who are in need. If the clothes are really worn out, we cut them into pieces and use them to clean the floor.

Simple eating habits

My family eat more vegetables and less meat. I often tell my family members not to eat junk food. Our cooking style is mainly steaming or boiling as it is healthier and saves energy.

Live on less energy

I also pay attention to the use of electricity. My family members get into the habit of turning off the lights when leaving a room. When we take a shower, we’ll set the water temperature to around 40℃. All these things are good for saving energy.

We hope that everyone can really do something to protect the earth.

九年级英语句型转换中等难度题查看答案及解析

People depend on plants. We use plants for food, cloth, shelter (住处), and even the air we breathe (呼吸).

Plants keep our air and water clean. Green plants give us oxygen (氧气). Oxygen is part of the air we breathe.

Plants are also part of the water cycle (水循环). Most of the water that a plant takes in goes back into the air.

Plants give us a lot of the food on the earth. Fruits, vegetables, and grains (谷物) come from plants. Without plants, we would not have bread, rice, carrots, apples, oranges, or bananas! Many people are growing plants to eat in their own gardens at home. Having your own garden helps the earth as well.

When you grow your own fruits and vegetables, you help cut down on pollution because big trucks don’t need to take your food to shops. You also help reduce the amount of rubbish because you don’t need to use bags for packing your food. You can just pick it out of the ground or off a plant and put it into a basket!

Trees are an important plant resource (资源). Trees provide wood to build homes and furniture. Trees are used to make lots of things around your home and at your school. And trees provide fruits that are good for you. Without trees, the earth would be a very different place.

1.________ is part of the air we breathe.

A.Sunlight B.Water C.Food D.Oxygen

2.What happens to most of the water that a plant takes in?

A.It goes back into the air. B.It stays in the plant.

C.It goes into the ground. D.It stays in the river.

3.What does the phrase “cut down on” mean in Paragraph 5?

A.Cause. B.Accept. C.Reduce. D.Expect.

4.What is the best title of the passage?

A.A Different Place B.The Uses of Plants

C.Food on the Earth D.Gardens at Home

5.You would find the passage in ________.

A.an interesting novel B.a book about animals

Plants and animals are largely made of water. So are humans. They need to keep enough water inside them, or they could die.

We get some of the water we need by eating food that has water in it. Drinks, such as milk and tea, are mostly water, too. A person needs water every day. If we go without water for three or four days, we will lose too much water from our bodies. In very hot weather, we could lose this water in just one day.

What does water do to help our bodies? Water helps to take the nutrition（营养）from food to our bodies. It also helps to take the wastes away from different parts of our bodies.

In our homes, we also need water for many things. We need water for cooking, washing and flushing（冲水）the toilet. About three quarters of the water is used in the bathroom and toilet. The rest is mainly used in the laundry（洗衣房）and kitchen.

___________It may come from a lake or a river. It may come from the sea, from the rain and snow or from the underground. Water rises from rivers and seas to make clouds, and then falls again as rain and snow. The water you drink has been around for millions of years. It just keeps being recycled.

Many people work hard to make sure we always have clean water in our homes. Water is very important for all living things, so we should use it carefully.
