I went to my first music festival—We Love Green. It was held over a weekend in a park in Paris. Like most music festivals, it had wonderful singers and music. However, there was something special about this one. You see, this was a green festival!
From the food to the stalls (摊位), everything was as environmentally friendly as possible. The festival was powered by solar energy. There were specially labeled bins (贴有标签的垃圾桶) so that the waste could be used again after the festival. Free fresh water was provided for everyone so that guests didn't need to buy drinks in plastic bottles. There were many stalls for everyone, from little children to the old.
II. 阅读理解
This seems like such a great idea to make something very fun and not cause great pollution to the environment. I have discovered that there are more events similar to this across the world! I really hope that there will be more events like We Love Green. These environmentally friendly practices tell people being green doesn't mean being boring. It can be quite fun. As a result, more people may be encouraged to consider the role they play in the environmental protection.

The earth is about 4,540 million years old. Man and his ancestors have been on the earth for about 6 million years. But we change our earth in many ways. Many things we do are good, but some are not good for the earth.
Water Pollution
A lot of people, birds and fish die each day because of water pollution. Factories pollute the water. As a result, the water in many rivers and lakes is now very dirty.

Soil (土壤) Pollution
In order to have a better harvest, some of the farmers use chemicals too much in their fields. That's bad for the soil.

It is widely agreed that the overuse of fossil fuels (化石燃料), such as coal and oil has caused serious environmental problems. Scientists are trying to find new clean energy that does not pollute the air, the water or the ground. Solar power is one.
Solar power is a kind of electricity which is produced by taking energy from the sun, using solar panels (电池板). The power is easy to get and will not be used up as long as the sun is there. Whenever it is sunny, there is the power. The power is clean and renewable. It helps to reduce waste and pollution, which is great for the environment. In the areas that are too far away to send electricity to or not easy to build electric power plants, solar power is especially necessary. It enables the people there to use lights, TVs, computers, washing machines, fridges and many other things.
Therefore, more and more countries, such as China, the USA, Japan and India, encourage scientists to develop practical technology to put solar power to use. However, the power is not as widely used as expected.
One of the challenges is that a solar power system needs sunshine. Countries or areas with a lot of rain, like the UK, are not suitable to develop such power systems. Secondly, a solar power plant requires a very large site to fix enough solar panels to collect sunlight and change it into electricity. Maybe an area in the desert would be one of the perfect places for such a plant to build. What's more, solar panels are expensive at present though the energy itself doesn't cost anything.
Today scientists are working hard to develop more practical and cheaper solar power systems. Maybe one day solar power will be one of the most important clean energy sources in our life.
11. Where is solar power taken from
A. The sun. B. The air.
C. The water. D. The ground.
A
解析: 细节理解题。根据第二段第一句可知, 太阳能是一种来自太阳的能量。故选A。
12. What do the underlined words “be used up” mean in Chinese
A. 被用完
B. 被滥用
C. 习惯
D. 短缺
A
解析: 词义猜测题。根据常识和第二段第二、三句可知, 只要太阳还在, 太阳能就不会用完。故be used up意思是“被用完”。故选A。
13. Why isn't the solar power used widely
①Because a solar system needs sunshine. ②Because the energy is too expensive. ③Because fixing solar panels needs very large sites. ④Because solar panels are expensive.
A. ①②③
B. ①②④
C. ①③④
D. ②③④
C
解析: 细节理解题。根据第四段内容可知, 太阳能没有被广泛使用的原因有: 太阳能系统需要阳光, 安装太阳能电池板需要很大的场地, 太阳能电池板很贵。故选C。
14. What's the main idea of Paragraph 4
A. The ways to use solar power.
B. The difficulties of putting solar power into use widely.
C. The places to build the solar power station.
D. The advantages of solar power.
B
解析: 段落大意题。结合上题解析可知, 第四段主要讲述了太阳能没有被广泛使用的三个原因, 因此第四段的主要内容是太阳能广泛应用的困难。故选B。
15. What can we know about solar power according to this passage
A. Solar panels don't cost anything at present.
B. Solar power is a kind of clean and useful energy.
C. Solar power will run out very soon.

假如你是李华, 近期你校开展了以“Saving Our Earth”为主题的环境保护项目式学习, 你的英国朋友Tom来信询问该活动的情况, 请你给他写一封回信。
内容包括:
1. 本次项目式学习的目的；
2. 谈谈为保护环境可以采取哪些具体措施。
注意:
1. 词数80左右；
2. 可以适当增加细节, 以使行文连贯。
Ⅲ. 写作
Dear Tom,
I'm glad to know you are interested in our school's project-based learning with the theme of “Saving Our Earth”.
The purpose of the project-based learning is to show the students the damage done to the earth and to raise the students‘ awareness of protecting the earth.
We should take some measures to solve these problems. It is necessary for us to go to school by bus or on foot, because it can reduce the air pollution. What's more, we had better plant more trees.
Environmental protection is closely related to our daily life. So it is everyone's responsibility to protect our earth.
Yours,
Li Hua
THANK YOU !
