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.

3 . By the year 2050, a fifth of the world’s cities will experience unprecedented climate conditions and environments that currently don’t exist in any major cities, according to new research. A team of scientists at the Crowther Lab in Switzerland produced the report, which described the climate for 520 major cities 30 years in the future.

The results showed that 77 percent of the world’s cities will experience a surprising change in climate conditions by 2050, and 22 percent of the 520 cities will see conditions that are not currently experienced by any existing major cities.

In China in 2050, the climate of Xi’an, in Shanxi province, will be similar to that of current day Maseru, the capital city of Lesotho in southern Africa, with the maximum temperature of the warmest month likely to increase by 4.59℃. Chongqing in southwest China will resemble the climate of Swaziland capital Mbabane, as the warmest temperature is predicted to rise by 5.1℃.

Scientists predict summers in Europe will get warmer by an average of 3.5℃ and European winters will see temperature rises of 4.7℃. London’s climate will be more similar lo Barcelona, and Madrid’s to Marrakech.

The Crowther Lab hopes the analysis will motivate decision-makers to take necessary steps to prevent or address some of the climate effects due to the threat of climate change. The report also found that cities in tropical regions will experience smaller changes in average temperature but will be controlled by shifts in rainfall regimes. This may lead to a noticeable increase in unexpected events, and severe droughts.

“Across all scientific fields, the greatest challenge in climate science is no longer the precise measurement of climate change impacts, but inspiring people to picture is actual effects in order to motivate action,” said Tom Crowther, senior scientist und founder of the Crowther Lab.

1. According to the research, among the 520 cities by 2050, about ________ cities will experience the climate conditions that no major cities currently have experienced.

A．400

B．114

C．260

D．104

2. How did the scientists prove their result?

A．By listing figures.	B．By making comparisons.
C．By doing experiments.	D．By explaining theory.

3. What is the Crowther Lab intended for?

A．To compare the climate change of the major cities of the world.

B．To inspire people to picture its actual effects in order to motivate action.

C．To inspire decision-makers to take necessary steps to prevent some climate effects.

D．To show most word’s cities will experience a striking change in climate conditions.

4. What is the best title of the passage?

A．World Temperature	B．Current Climate Change
C．Big Titles in the World	D．Future Climate Change in Most Big Cities

4 . Many of us spent our childhoods dreaming of becoming astronauts.However, the hard reality is that only a select few will make it.    1    Not necessarily.

In fact, some of the space jobs are not only for astronauts and they all sound just as cool.One of the most interesting space jobs that you may have never heard of is “chief sniffer （嗅探员）NASA has already hired a chief sniffer named George Aldrich, whose job is to smell materials before they are used in spacecrafts.

    2    A spacecraft is of limited size and relatively high temperature, which makes smells stronger inside of it."Once a spacecraft is launched, astronauts have no way of escaping unpleasant smells." Aldrich told The Telegraph.More importantly, smelling objects can help identify dangerous chemicals that could threaten astronauts' health.

Another job, the “space tour guide”， may seem a little ahead of its time ——after all, what's the point of hiring a tour guide when there aren't any tourists there? But now, many private companies are starting to provide space trips, and wealthy space enthusiasts such as Justin Bieber and Sarah Brightman have already signed up for tours.    3    

Being a space tour guide requires rich knowledge of astronomy, astrophysics, geography and history to help passengers get the most out of their journey.    4    

Astronauts often spend weeks or even months in a small capsule with the same group of people, which is why a “space psychologist” is also needed to help astronauts overcome mental challenges, like feeling bored and lonely.

Rohit Talwar, chief executive of US company Fast Future Research, said, "We're crossing the boundaries（界限）between science fiction and reality.    5    ”

A．But does that mean you'll never get the chance to work in space?

B．Modern astronauts led less lonely and helpless when they work as a group.

C．There is almost no possibility that normal people will be able to a fiord space travel.

D．Things we've seen in the past in movies are now becoming real career opportunities.

E．Using your nose at work might sound a little strange, but the job is actually very important.

F．It may not be long before space becomes one of the top travel destinations for human beings.

G．Tour guides also need to be excellent storytellers to help experience the amazement of space travel.
