3) Environmental Pollution 4) Saving WaterPassage 1Passage 2Passage 1 The world is not only hungry, but also thirsty for water. This may seem strange to you, since nearly 75% of the earth’s surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3%—the fresh water that comes from rivers, lakes, under ground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.Saving Watericeberg [?aisb?:g]Titanic struck an iceberg and then sank
to the bottom of the sea.A glacier is an extremely large mass of ice which moves very slowly, often down a mountain valley. glacier [?gl?si?]? However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly— almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry.
We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. These systems are as important as the spacecraft for our future.He’s growing stronger and stronger day by day. She drinks coffee day after day. What’s the difference between day by day and day after day?Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. Please paraphrase this sentence.Passage 2 World Environment Day (WED) is a day we all need to put in our diaries. It happens on June 5 every year and should be one of the most important days of the holiday calendar. WED was created in 1972 by the United Nations General Assembly. The environment wasn’t such a big issue back then. But it is one of the hottest topics in the world today. WED helps raise worldwide awareness of the threats to our environment. Many environmental agencies organize events based on different themes each year. These events encourage both governments and local communities to work together to tackle environmental problems from a grass roots level and at a presidential level.World Environment Day What’s the Chinese for these two phrases?According to the calendar, June 5 is
the World Environment Day. Many people in rich countries are aware of today’s environmental issues. Even though many of the world’s citizens know the issues, too few people do enough to deal with them. WED could be the day to start changing our lifestyle forever to reduce our carbon footprint. Most of us use far too much energy. With a little thought, we could all use less power and help the environment. WED also needs to make people in poorer countries aware of the dangers to the environment. The governments of new superpowers need to reduce their energy consumption, too. Hopefully, World
Environment Day will become more celebrated every year.What does celebrated mean?Read the 2 articles carefully and decide whether the following statements are true or false. Correct the false one(s).____ 1) Nearly 97% of the earth’s surface is covered with water.
