1 . Nowadays, everyone seems to hope to go into space and live on new planets. Instead of depending on another pre-existing planet, could we make a new planet by ourselves?
First of all, if we were to live on it, we should find a good place in space to put the new planet. We would want it to be in a habitable zone, which means the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid water.
We’d also need the right materials to make the planet. Our Earth is made up of many different elements (元素). If we made our own new planet, we’d probably want it to have similar elements and a similar structure (结构). We’d also want enough water to form some oceans.
But even if we get all of the materials, creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.
We would probably also need a lot of food because there is going to be many scientists and astronauts out in space working on this project!
According to NASA, each astronaut uses about 0.83 kilograms of food per meal, including 0.12 kilograms of packaging (包装) material. Without the weight of the packaging material, we’d need about 780 kilograms of food just to feed one astronaut for a year.
Putting all these together could make it possible to make our own planet one day! In fact, creating a new planet would probably require a very modern technology and there would be tons of other things to think about. And if this is possible, it won’t likely happen within a very long time.
1. To create a new planet, which of the following should we first do?| A．To collect materials similar to Earth. | B．To prepare plenty of food for astronauts to eat. |
| C．To design its inner structure. | D．To find a proper place to set it. |
| A．About 0.12 kilograms. | B．About 0.71 kilograms. |
| C．About 0.83 kilograms. | D．About 0.95 kilograms. |
| A．It is a waste of time and money. |
| B．It may be a dangerous thing for humans. |
| C．It is impossible to come true in the near future. |
| D．It should be one of NASA’s next plans. |
2 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.
In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.
In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.
Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.
Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?
1. Which of the following best explains “vanished” underlined in paragraph 1?| A．Settled. | B．Spread. | C．Disappeared. | D．Decreased. |
| A．Robots can work in different places. |
| B．Robots have much to be improved. |
| C．Robots work for humans for free. |
| D．Robots have many advantages. |
| A．He probably disagrees with the idea of human cloning. |
| B．He is looking forward to using of cloning technology. |
| C．The scientists have already discovered how to control genes. |
| D．The scientists will face many difficulties of controlling genes. |
| A．High-tech Cars | B．Life in the Future |
| C．Is Cloning Really Good? | D．Are You Ready for the Future? |
3 . What will man be like in the future--in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example, Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald (光秃的).
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. But in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own.
1. The passage mainly tells us that ________.| A．humans need’t wear glasses in the future. |
| B．man’s life will be different in the future. |
| C．future man will look quite different from us. |
| D．man is growing taller and uglier as time passes. |
| A．predict | B．think | C．compete | D．know |
| A．future life is always predictable (可预测的) |
| B．human beings will become less attractive in the future |
| C．less use of a bodily organ (器官) may lead to its degeneration (退化) |
| D．human beings hope for a change in the future life |
| A．Colour and height | B．size and appearance |
| C．thought and observation | D．thought and emotion |
4 . With the rapid development of science and technology, we don’t know how different our life will be in the future.
At first we think about human relationships. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet — even our husbands or wives will be met in this way.
Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.
We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true.
Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather confident about our future.
| A．However, we are convinced of the following |
| B．We should be happy and believe good things will happen |
| C．We will pay more attention to protecting the environment |
| D．We can only imagine it |
| E．Spending holidays will also be completely different |
| F．It will be much faster and easier for us |
| G．Our environment will be more polluted |
5 . What do you plan to do when you retire? Keep working? Get more exercise? Or learn something new? You may put them on hold. There's a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars.
On Thursday, National Geographic will show the first-ever Mars show home, giving earthlings (地球人)an idea of what their life could look like on the Red Planet. In the not-so-distant year of 2037, the igloo-shaped structure could be the home of your future.
It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognizable — a kitchen, a bedroom — but there are fundamental differences that are important to human survival.
As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent (永久的) shelter from the sun；society will move largely indoors. Most buildings will be connected by underground passages and the houses won't have windows. The homes will have simulated solar lighting, or natural light that has been bent several times. Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays (光线)that can pass through six feet of steel, and a double air-locked entrance to keep the home under proper pressure.
"We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre, 99 says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci-fi. “10 to 20 years from now there will certainly be people on Mars,” Petranek says.
“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will, ”Petranek says. But two main factors have “completely swung public attitudes”.
The private companies’ participation has forced government agencies to speed up their game, and influential films such as Gravity and The Martian have caught society’s eye.

6 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?
1. What does paragraph 2 mainly tell us about mobile phones?| A．Their target users. | B．Their wide popularity. |
| C．Their major functions. | D．Their complex design. |
| A．Admit. | B．Argue. |
| C．Remember. | D．Remark. |
| A．They like smartphone games. | B．They enjoy guessing callers’ identity. |
| C．They keep using landline phones. | D．They are attached to their family. |
| A．It remains a family necessity. |
| B．It will fall out of use some day. |
| C．It may increase daily expenses. |
| D．It is as important as the gas light. |
7 . “Human activity has wiped out two-thirds of the world’s wildlife since 1970,” CNN reported on September 10, 2020. Later that month, the Guardian reported that “40 percent of the world’s plant species are at risk of extinction”. Stanford biologist Paul Ehrlich and his colleagues argued that “the ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization”. Around the same time, the Daily Mail warned that “human civilization stands a 90 percent chance of collapse within decades due to deforestation”.
These horrible calculations and projections come from authoritative-sounding reports issued by international agencies, conservation groups, and peer-reviewed scientific journals. But is the future of wild nature and human civilization really so poor?
Data from uncontroversial mainstream sources strongly indicate that both humanity and the natural world are likely to be flourishing rather than collapsing at the end of this century. Humanity is becoming an urban species, and that’s good for the environment, since urban dwellers generally use less electricity, produce less globe-warming carbon dioxide, and have smaller land footprints than people living in the countryside. By 2100, it is estimated that 85 percent of people will be city dwellers, which would leave only 1.2 billion still living in the countryside. That means more space for the wildlife and less pollution from the agriculture.
The global tree-covering area increased by 865,000 square miles between 1982 and 2016. The researchers found that gains in forest area in the mild, subtropical and northern climatic zones are offsetting declines in the tropics. The Maryland researchers owe much of that increase to “natural afforestation on abandoned agricultural land”. “Furthermore, forests in mountainous regions are expanding as climate warming enables trees to grow at higher altitudes,” they added.
Humanity does face big environmental challenges in the coming century. But the scientific and economic evidence shows that most of the trends are positive or can be turned in positive direction by human wisdom. Rather than an age of extinction, the 21st century promises to be an era of environmental renewal.

8 . Since I became a teenager, I have thought a lot about my own future job and set goal for it. It’s very necessary and important for me now to decide what I want to become.In the past, I used to want to be an engineer because I’m good at drawing and building stuff, but my thought has changed through time. I end up all of my choices as a manager who manages the whole system in the service hotel.I have planned that I will study hard in high school, then finish IGCSE and IB with a high score. After that, I will move to a good school in USA to learn about business and the economy in my country.
During my life in university, I properly will apply to work for some small stores and hotels to have the feeling of how things work in the real life. Firstly, the reason I like to be a hotel manager is I find it interesting to use techniques to persuade more people to stay at the hotel. Secondly, I see that the development in business is the fastest growing in sectors of industry besides the primary and the secondary, so I can make a lot of money. Thirdly, it’s the range of community; it has a very high range to meet different people with different nationalities.
Fourthly, I want to have more confidence and become a good leader with skill, for example, I still can’t control and persuade people to listen to me sometimes when I’m in charge of PE’s lesson. The last reason why I strongly chose to be a hotel manager is because of my pressure from my family. They are the second generation of successful 3 stars hotels’ managers. They like me to become what I’m going to do when I become a manager.

9 . In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles. Today, however, environmental problems have taken over as the greatest risk to life on Earth. Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy. But they are also preparing for the worst: what can we do if the terrifying scenes in films such as The Day After Tomorrow happen in real life? What is our plan B for Earth?
One option is to explore other planets to see if we could live on them. The most likely choice is Mars, which is relatively close to Earth and has an environment less hostile than that of other planets. Mars has fascinated people since ancient times, and today our interest in Martian exploration is greater than ever before. Besides, more governments are making efforts to educate the public on the Red Planet.
There is no doubt that humankind is drawn towards Mars. However, sending people there will require all the skill, courage and intelligence. While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation. And even if the first settlers do reach Mars safely, they may not be able to return to Earth — ever. Staying alive will be a daily challenge, but as proved by the Biosphere 2 experiment, not impossible. As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert, consisting of a closed space in which people, animals and plants could live together. Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.
For now, human settlement of Mars is still decades away. Until we are finally able to live on another planet, we need to take much better care of our own. Right now, it's the only one we have!

10 . What will man be like in the future? How about in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today.
Let's give an example. Man, even 500 years ago, was shorter than he is today. Now, on the average, men are about three inches taller. 500 years is a relatively short period of time, so we may guess that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity(容量). As time goes on, however, we shall have to use our brains more and more---and finally we shall need even larger ones!
But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at!
| A．Nowadays our eyes are in constant use. |
| B．This probably brings about mental changes. |
| C．These, as a result, are likely to grow weaker. |
| D．This is likely to bring about physical changes, too. |
| E．That's because man is slowly changing all the time. |
| F．As a result, future man will have little in common with us. |
| G．In spite of all these changes, future man will still have a lot in common with us. |
