The sun,the stars,a lighted lamp are the examples that can be seen by their own light.But most of the things you see are not giving off light of their own.They are just reflecting light that falls on them from the sun or some other luminous bodies.The moon,for example,doesn't give off any light of its own.It is not 1uminous.You see it because sunlight falls on it and some of the sunlight reflects on the earth.So moonlight is only second--hand sunlight. When you look at a book,it sends some of the light which fails on it to your eyes,and you see the book.If light could be kept out from where you're so that there would be no light from the book to reflect.Then you couldn't see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you're reading to your eyes is as short as if there were no time at time.Light reaches us from the moon,which is about 380,000 kilometres away,in only a little more than a second. Question: Light travels about  _  kilometers per second. Options: A: 300,000 B: 100,000 C: 400,000 D: 190,000

Read the article and select the best answer. Article: Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals, and fish. The lake water is polluted. It is in a colour of dirty brown, and it is filled with strange plants. How did this happen? First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all round Lake Ponkapog, so the rainwater was clean. Now there are many homes around the lake. People often use the chemicals  in their gardens. They use other chemicals inside their houses for cleaning and killing insects. There are also many businesses. Businesses use chemicals in their machines of shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from home and businesses and then carries them into the lake . They pollute the water and kill the animals. Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats . But oil and gas from boats often get into the lake. So more bad chemicals go into the water this way. People in Hartwell are worried . They love their lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at other chemicals on the ground. And they mustn't use motorboats any more on the lake. All these may change people's lives. Only then can Lake Ponkapog be a beautiful, clean lake again. Question: To save Lake Ponkapog, people need to   _  . Options: A: be more careful about chemicals B: use the water C: grow fewer plants in the gardens D: use more motorboats on the lake
