If you look down at our planet from outer space, most of what you see is water. In fact, oceans and seas cover more than 70 per cent of the planet's surface. Millions of years ago, there were no oceans on the earth. The surface of the earth was very hot, so water boiled away. As the earth cooled down, steam in the air began to fall down as rain. It rained and rained for many thousands of years and made the first seas on the earth.
Oceans are a large and wonderful world full of strange and interesting animals and plants. More than 275,000 kinds of fish and other animals live in the ocean. Most of them live in the surface waters because there is enough food there. But there are also some unique animals in the deepest part of the ocean. Some animals live their whole life in the ocean (such as whales) and others can spend time in the ocean or on land (such as sea lions). They are very important to our life.
Believe it or not, half of the oxygen
（氧气）we breathe is produced by algae（藻类）, the oldest plants on the earth! Each year we eat about 29 million tons of fish, much more than cattle, sheep and eggs. Without the oceans, we cannot live!The oceans are also rich in minerals
（矿物）, oil and natural gas and many other resources. Every natural element can be found in the ocean. About 3.5 per cent of ocean water is made up of salt which we eat every day. Nearly one-third of the world's oil comes from our oceans. In fact, there is a lot of gold in ocean water, too. If all the gold in the world's seawater were mined（提炼）, each person on the earth could have about four kilograms of gold!True or false:
(1) Water covers over 70
％ of the earth's surface.( )
(2) Oceans are a large, wonderful world full of strange, interesting animals.
( )
(3) All the animals in the oceans live in the surface waters.
( )

I think it is good that many families keep animals 1. pets. Unfortunately, some people do not take good care of their pets. Some do not feed their pets enough so they become 2. . Others do not give their pets a good place to 3. in and the animals can get too hot or too cold. There are also a few people who 4. their pets. I feel this is wrong. People should not treat their pets badly.
The government of the UK is thinking of 5. to help protect pets – it’s about time! It wants a set of instructions on 6. to take care of different kinds of animals. The instructions would 7. explain how to keep animals happy! That is good news for pets, don’t you think so?
The UK government also wants to create some 8. ‘pet police(政策)’. They can go to people’s homes to check whether they are taking care of their pets 9. . If they find someone treating an animal badly, they can take the animal 10. . People who hurt their pets can even go to jail(监狱). I hope more people will now try to take better care of their pets.
