We know almost half the world is urban(都市的) now – but what will our world look like in the year 2100?

It took about a million years for the global human population to come up to 1 billion in 1800. In the next 200 years, it came up to 6 billion, and it will take only about 20 more years to add another billion. By 2100, the United Nations estimates that the global population will attain more than 10 billion.

By the end of 2008, slightly less than 50 percent of the global population lived in cities. If economic development proceeds at today’s pace, over the next century or so it is highly likely that 8 billion people will live in urban centers, up from today’s roughly 3.3 billion. Yes, the world will indeed be able to hold so many people. The major reason is urbanization(城市化). There will be many more new cities in the year 2100, and some of today’s large cities will become super cities, including Beijing, Delhi, Mumbai, Sao Paulo, Shanghai and so on. At the same time, recent advances in agriculture, energy, and water technologies suggest that human creations will keep up with population growth. Rural areas will return to an agrarian (农业的)centre to feed the growing cities. Languages will drop from the current 7,000 across the globe to less than a few hundred. English will be the primary language of the world.

As we compress(压缩) people into the urban center, and as we leave behind the rural areas to feed us – will we really live a happy life at that time? We will have to live together in large buildings in cities and save on energy and services delivery cost. There will be few chances for us to get close to nature. We really need to think about the effect of the things we have done and are doing now!

1. The underlined word “attain” in the second paragraph probably has the same meaning as “________”

A. increase      B. gain     C. reach     D. limit

2.  With the development of urbanization, people in 2100 will have to      .

A. stay in urban areas and have no chance to get close to nature

B. develop industry rather than agriculture to create job opportunities

C. live a poor and unhappy life because there will be less energy to use.

D. make more creations in agriculture, energy, and water technologies

3.  What is the author’s attitude towards urbanization?

A. supportive    B. disappointed   C. surprised    D. worried

4.  What is the best title for this passage?

A. Global urbanization in the year 2100

B. The primary language in the future

C. Reasons for the rapid increase of population

D. The development of agriculture in 2100

阅读下面短文，并根据短文后的要求答题（请注意问题后的字数要求）。
Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.
But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.
Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.
“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”
