620 m3 water | If we put fresh water and sea water together, we can each have 620 m3 water. But remember, sea water is too salty for us to drink if the factories don’t process it first. So, 620 m3 is little. Saving water in daily use is important. |
0.5 hectares of forests | There are 3.869 billion hectares(公顷) of forests on Earth. But we are losing them mainly because we cut trees too much. If we calculate(计算)at the size of a football field, we are losing 343,000 football fields every day, or 1,431 per hour, or 24 per minute! |
1.5 centimeters long corals(珊瑚) | All the corals that we have now spread for about 100,000 km in 109 countries. But each of us can only have such a little piece, because seas are getting polluted and corals are dying. |
33 stars | According to the latest report, there are 200 billion stars in the Milky Way. Each of us can have 33 of them. Unfortunately, we cannot see most of the 200 billion stars from Earth. We can only see about 6,000 stars. If we don’t use telescopes or we have bad weathers, we can only see about 2,000 stars. |
90kg rice | On average, we harvest 0.54 billion tons of rice each year round the world and each of us can have 90 kg. Asia produces and eats 90% of all the rice. How long will it take you to eat up this 90 kg rice? |
1 iceberg | Luckily, we still have icebergs to share when Earth gets warmer and warmer. Each of us can have an iceberg of 170m×170m×170m. Up to 10% of Earth surface is covered by ice. There is 31,000,000km3 of ice on Earth in all. |
A.over 620m3 | B.more than 620m3 | C.far less than 620m3 | D.only 620m3 |
A.the man-made damage | B.the climate change |
C.the construction of many football fields | D.the environmental pollution |
A.all the stars | B.about 2,000 | C.about 200 billion | D.about 6,000 |
A.less water | B.fewer icebergs | C.fewer corals | D.less rice |
Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite(相反的) to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your lunch and super!
