Write a paragraph about an interesting world mystery you have heard of. Using present and past modals of certainty, speculate on the causes and possible explanations. Use one of the following topics or choose your own:
1. How were the great pyramids in Egypt built?
2. Are humans really to blame for the melting of the ice in Greenland and Antartica?
3. Does the Loch Ness monster really exist?
4. How did the great statues get to Easter Island.
You can see an example in the grammar book on p. 83, exercise 10.
1. The pyramids must have been built by slaves, Egyptians are known for their pharaohs, they wanted these huge pyramids for people to remember their leadership. So those theories about UFO's building the pyramids might be wrong and impossible
ReplyDelete2. I think the activities of humans should be one of the reasons that causes the melting of the ice in Greenland and Antartica. The more cars are used, the more products are produced, the more trees are cut, the more pollution our humans generate, all of them could make earth warmer and ice easier to melt. But the earth has its own characteristic of regular evolution, the melting of the ice might be one of the necessary stage of earth developing in the whole period. In ancient times, there must have melted of the ice so many times. The earth could have existed in the ice age and melting ice age alternatively.
ReplyDeleteHumans should be one of the important reasons of the melting the ice in Greenland and Antartica. Because several years ago, we couldn't see that. There was less people in the world and industries. Now every bad thing are increasing such as pollution. Some places which could have been cool or a little warm are becoming really hot. The pollution must have destroyed the ozone layer and induced the heat.
ReplyDeleteI think Loch Ness monster really exist.Even though today's scitentist is developing. We still have something that we don't understand. Loch Ness monster might exist. Maybe we just don't know this kind of life.
ReplyDeleteHuman does not have responsibility melting ice on the earth.
ReplyDeleteBecause It is a tremendous changeing of the nature.
Human making carbon dioxide gases are one of reason warming the earth.
However, there are another scientific evidences.
There are more serious gas effecting to increse the earth temperature, earth itself.
It is methane. This gas is twenty one times stronger than carbon dioxide to warm the earth.
The methane sould be exist in the past. It might warm the earth in the past also.
I should topic NO 5 which is Mermaid. Last month, any newspaper as well as the Internet published some novel evidences about videos scientists caught when they explored underwater. After this debatable topic got everyone eyes, many people believed that Mermaid must have existed. In my opinion, I think that Mermaid have already become extinct, because when I saw this video I realized that it was fake. Therefore, the more technology becomes advance, the more realistic movies have been made.
