In 1896, Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class and the same interest in physics brought them together and they became good friends. Before long they fell in love. In 1903 when Einstein was 24, he married Merits, who was 4 years older than he.
After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Merits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home.
In1914, Einstein moved to Berlin and settled down there. At that time his theory proved to be correct and he had become famous all over the world. But it was not long before the First Would War broke out. Merits as well as her two sons, who were on holiday in Switzerland, couldn’t come back to Berlin any more. The war not only stopped Einstein’s work but also broke up the warm, happy family. In 1919, Einstein and Merits had to get divorced(离婚).

For years scientists have been worried about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside.
Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. When builders began making houses and offices, they did not want to waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also used man－made building materials which are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building green plants.
Scientists believe that a plant's leaves absorb the pollutants (污染物). In exchange the plant lets out oxygen through its leaves. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants.
1.Indoor air pollution may be more dangerous than the air outside mainly because .
A. the building are too high
B. the flow of air indoor is limited
C. the building materials are harmful
D. people don't want to waste energy
2.Some kind of indoor pollution can be found in .
A. all kinds of offices B. all kinds of houses
C. every modern house D. every old house
3.In the last paragraph the word“ absorb” may mean .
A. take in B. bring up C. give out D. turn into
4.Scientists believe that plants can .
A. change oxygen into pollutants
B. absorb all the pollutants
C. make your houses more prettier
D. absorb pollutions and let out oxygen
5.According to the last paragraph, we should to clean the air.
A. plant all kinds of plant

The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our plant, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere(大气层) with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

B. Because the land is covered with water
C. Because people there can not live at the temperature of zero.
D. Because wars break out among countries.
4.By giving the example of dinosaurs, the author tries to prove______

My First Day
