Everybody knows that Earth spins from west to...

Everybody knows that Earth spins from west to east. That is to say, it appears to be spinning counterclockwise(逆时针) when viewed from above the North Pole.

But what if Earth started spinning the other way?

Scientists from Germany have made a computer simulation(模拟) in which Earth spins in the opposite direction – clockwise when viewed from above the North Pole. This showed them some interesting things about the weather and topography (地形地貌) on Earth, Live Science reported.

As Earth spins in a counterclockwise direction, it shapes ocean currents(洋流). The direction of the spin, together with wind, produces different weather around the globe(全球).

But a backwards(逆向的) spin changes the ocean currents and winds. Therefore, the climate(气候) is different. Western areas of continents(大陆) on Earth cool down as the eastern parts warm up. Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planet’s wettest places.

Another result of a backward spin is that Earth becomes greener. Scientists found that global desert(沙漠) coverage(范围) shrank(缩小) from 42 million square kilometers to 31 million square kilometers. This may have something to do with the changing climate.

Therefore, you can see lush(郁郁葱葱的), green landscapes from Central Africa to the Middle East, which are mostly covered by deserts now. More surprisingly, the Sahara Desert becomes an oasis(绿洲).

___________. They just appear in some places that they never appeared in before. Deserts would cover North America, where countries like the United States and Canada lie. Sand dunes(沙丘) would replace the Amazon rainforest in South America.

A backward spin would keep the major characteristics of Earth’s topography, such as the size, shapes and positions of continents and oceans. But it would also change the interactions between circulating(环流) air, ocean and topography, lead scientist Florian Ziemen told Live Science.

1.What condition did the German scientists use for the simulation?

A. Earth spins from east to west. B. Earth spins from west to east.

C. The North Pole is turned upside down. D. Earth moves around the South Pole.

2.Why would the climate be different if Earth spins backwards?

A. Because there won’t be any more large oceans.

B. Because the ocean currents and winds will be changed.

C. Because it will change the amount of sunlight that Earth can receive.

D. Because Earth will become greener without deserts.

3.What will a backwards spin bring to the Earth?

A. Winters will become colder. B. No rain will fall in summer.

C. Eastern Russia will become warmer. D. The Sahara Desert will become smaller.

4.The story tells us that _____.

A. Earth used to spin in the opposite direction

B. a backwards spin would cause interesting changes on Earth

C. global desert coverage has been shrinking(缩小)

D. a backwards spin would change Earth’s topography completely

5.Which of the following sentences can be put at the beginning of the eighth paragraph?

A. Sadly, deserts would cover North America.

B. Luckily, deserts would disappear.

C. Anyway, deserts would replace the Amazon rainforest.

D. However, deserts don’t disappear.

Everybody knows that Earth spins from west to east. That is to say, it appears to be spinning counterclockwise(逆时针)when viewed from above the North Pole.

But what if Earth started spinning the other way?

Scientists from Germany have made a computer simulation(模拟)in which Earth spins in the opposite direction-clockwise when viewed from above the North Pole. This showed them some interesting things about the weather and topography(地形地貌)on Earth, live Science reported.

As Earth spins in a counterclockwise direction, it shapes ocean currents(洋流).The direction of the spin, together with wind, produces different weather around the globe(全球).

But a backwards spin changes the ocean currents and winds. Therefore, the climate(气候)is different. Western areas of continents(大陆)on Earth cool down as the eastern parts warm up.　 Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planet's wettest places.

Another result of a backward spin is that Earth becomes greener. Scientists found that global desert(沙漠)areas reduce from 42 million square kilometers to 3l. million square kilometers. This may have something to do with the changing climate.

Therefore, you can see rich green landscapes from Central Africa to the Middle East, which are mostly covered by deserts now. More surprisingly, the Sahara Desert becomes an oasis(绿洲).

_______ . They just appear in some places that they never appeared in before. Deserts would cover North America, where countries like the United States and Canada lie. Sand dunes(沙丘)would replace the Amazon rainforest in South America.

Everybody knows that Earth spins from west to east. That is to say, it appears to be turning counterclockwise (逆时针) rapidly when viewed from above the North Pole. But what if Earth started spinning the other way?

Scientists from Germany have made a computer simulation in which Earth spins in the opposite direction—clockwise when viewed from above the North Pole. This showed them some interesting things about the weather and geography on Earth, Live Science reported.

As Earth spins in a counterclockwise direction, it shapes certain ocean currents(洋流). The direction of ocean currents, together with winds, produces different weathers around the globe. But a backward spin changes the ocean currents and winds. ▲ Western areas of the lands on Earth cool down as the eastern parts warm up. Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planet's wettest places.

Another result of a backward spin is that Earth becomes greener. Scientists found that global desert(沙漠) areas reduce from 42 million square kilometers to 31 million square kilometers.

A backward spin would keep the main features of Earth's geography, such as the size, shapes and positions of lands and oceans. But it would change the interactions between circulating air, ocean and geography lead scientist Florian Ziemen told Live Science.

1.Which of the following sentences can be put in the blank of Paragraph 3?

A.Anyway deserts cover the planet. B.Therefore, the weather is different.

C.However the positions of oceans changes. D.Surprisingly the area of lands is larger.

A.a place in a desert where there is sand and stones all over

B.a rich land in a desert where the water table is near the surface

C.a large body of salt water partially enclosed by land or an ocean

D.a large smooth area which is over 500 metres above the sea level

3.What would a backward spin bring to Earth?

A.The direction of ocean currents and winds would be different.

Everybody in this world is different from one another. But do you know that understanding differences can help you better manage your money?

As we grow up, we gradually（渐渐地）develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it’s not easy to change later in life. Financial experts（财务专家）say that everyone also has their own belief of how to manage their finances. This is the part of our value system and it has a great influence on the way we look after our money. According to our different values, experts put us in three categories（类别）.
