21、Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.
Astronauts will put waste items made of plastic into the recycling machine, called the Poistrusion Recycler. When they press a button, the Recycler will melt down the plastic and turn it into 3D filament (长丝).
The filament will e used in a 3D printer on the ISS-called the Refabricator-to make tools, spare parts and satellite components.
The waste will come from packaging materials, food containers, trays and eating utensils (器具) used on the ISS. Astronaut currently use disposable wet wipes to clean their food containers and utensils. The used wipes are stored as trash (垃圾), and replacement wipes must be sent up to the ISS on cargo missions.
By recycling old food containers and utensils, astronauts will reduce the amount of trash they produce. To get rid of trash from the ISS, astronaut load it into empty cargo capsules (航天舱) and release it into space. The capsules burn up when they enter Earth’s atmosphere.
Turning trash into useful new items will also help NASA save money because astronauts will need fewer supplies. It costs about $ 6,000 for every kilogram launched into orbit. These benefits will be even more important for longer missions in the future-such as the two-year journey to Mars. Astronauts will be able to recycle old waste materials into new tools and parts as they need them.
Tethers have successfully tested the systems in its laboratory. They will test it on the ISS in late 2018. The company is also developing a version of the system for use here on Earth.
【1】What material are the forks and knives for astronauts made of?

A. Reuse the trash.
B. Send the trash to Mars.
C. Take the trash to the earth.
D. Load the trash into empty capsules and throw it away.
【4】What is the biggest benefit of the new technology mentioned in the text?
A. It can save some space for the ISS.

22、When you throw something in the recycling bin, do you think about what it could become? And when you do, does it make you more likely to use that recycling bin? Recently, a study was conducted in an effort to decide whether or not explaining to people what their recyclables are transformed into would help increase recycling rates.
The researchers started with a group of 111 college students, asked to draw on paper before watching one of three ads.One was a public service message that showed paper going into recycling bins.The other two also showed the paper either being transformed into new paper or a guitar.After completing a survey, the students were asked to deal with the paper when they left. Half of those who saw the first ad recycled their paper, while the recycling rate jumped to 80% for those who'd seen the other ads.
After doing a few more lab experiments, the researchers headed into the real world.At a party, volunteers spoke with attendees (出席者) about recycling, with half mentioning transformed products and half keeping it general.They discovered the subject of the talks came into play.After the game, the recycling and trash bags were weighed.Those who received a message recycled over half of their waste, while those who did not recycled less than a fifth.
All this is to say that details matter.People want to know what treasures their trash can become, and when that's laid out clearly, they' re more likely to do it.Perhaps recycling companies should redesign signs to describe the items being created.Recycling is far from a perfect solution,but it doesn't hurt to manage to improve its rates.
【1】What's the function of the first paragraph?
A.To lead to the main topic.

B.Find perfect ways of recycling.
C.Examine the details of items.
D.Show the transformation of waste.
【4】In which column of the website does the text probably appear?

23、 Who can forget their first day of school? Students come into the classroom wondering who their teacher will be for the year.【1】Introducing yourself to those students is a big part of that first day.
Pay attention to your appearance.
Dress professionally and make sure you follow any published dress codes applying to students and staff. While you want the students to enjoy their time in your class, you want them to respect you.【2】On the first day, putting your best appearance forward can set the tone for the year.
Tell personal interests and hobbies.
【3】It helps them identify with you as more than just a teacher. Students may be surprised you have interests after school. Explaining some of your hobbies and interests can give students the chance to interact with you on the first day. Offering these small personal details can make you seem more approachable and will open up to a connection with your students.
Explain classroom rules.
Getting started on the first day by also explaining your class rules and what your class can expect of you is a good way to set guidelines. For example, you could say “I’m easy-going, but I do have some rules that everyone must obey.”【4】
【5】
If you have time after your basic introduction, ask your new students if they'd like to know anything more about you. After you have answered their questions, ask the class what they have learned about you. For example, ask "What do I like to do in my free time?" By doing that, you're reiterating your introduction, which makes it easier for the students to remember you.
A.Give name details step by step.
B.Invite questions and responses.
C.Tell your class a little more about yourself.
D.Teachers are faced with new students sitting in desks.
E.Continue to remain polite and positive when speaking to students.
F.Dressing in inappropriate clothing can be destructive in the classroom.
G.Keep those rules easy-to-remember if you introduce yourself and the rules together.
24、 There are around 100 tribes that live in global isolation, mostly in South America and India.
The Sentinelese(250 people)have lived on one of the Andaman Islands in Eastern India for 60, 000 years. They protect their island by fighting against people from outside. Their language is different from any other known language.
Another Andaman tribe is the Jarawa(300 people). In the past, they were independent and fought against anybody trying to make contact with them. But in 1998, the Indian govemment built a road across their land, and since then, they’ve had more contact with the outside world.
Some Amazon tribes avoid contact because of unhappy memories. The Mashco—Piro left their vegetable gardens after rubber companies killed most of their tribe at the beginning of the 20th century. Those who survived became nomadic(游牧的)and started hunting animals in the forest.
The Awa live in the Amazon forests of Brazil. Out of 350 members, 100 have no contact with the outside world. They left their villages and adopted a nomadic lifestyle around 1850 to escape attacks by Europeans. In the following years, farmers in nearby communities started cutting the trees to expand their farmland. The Awa lost most of their hunting land.
The few Amazon tribes that still exist are fighting to keep their traditional way of life.
Survival, an organization that fights for the rights of tribal people, says that uncontacted tribes are the most vulnerable(弱势的)humans on the planet and that’s why their environment should be unavailable to the rest of us.
After years of pressure, the organization got Brazil’s government to clear invaders from the Awa land. All non-Awa people are leaving so the tribe can get their forest back. But some think it’s impossible for tribes to stay isolated forever in a connected world. Contact will be made one day. So the question is:Whose choice should it be, ours or theirs?
【1】What could be learnt about the Sentinelese from the text?

【2】Why did the Awa adopt a nomadic lifestyle?
A.To avoid being attacked by Europeans.
B.To avoid being robbed by rubber companies.
C.To protect their hunting land.
D.To maintain their traditional way of life.

26、Directions:Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
Whatever happened to the fight of carbon capture?
Debates have been going on around the subject of carbon capture. Scientists, especially engineers and geologists, have strongly criticized green groups who claimed that carbon capture and storage (CCS) schemes are costly mistakes.
The scientists insisted that such schemes are vital weapons in the battle against global heating. They also wan that failure to set up ways to trap and store carbon would make it impossible to meet the emissions target by 2050.“CCS is going to be the only effective way in the short term to prevent our steel industry, cement manufacture and many other processes from continuing to pour emissions into the atmosphere,” said Professor Stuart Haszeldine, of Edinburgh University. “If we are to have any hope of keeping global temperature increases down below 2 degrees Celsius, we desperately need to develop ways to capture and store carbon dioxide.”
Green groups claimed CCS would not make “a meaningful contribution to 2050 climate targets”. They say CCS was not a reliable way to decarbonize the energy system and that CCS has a “history of over-promising and under-delivering”. Instead, they urged the construction of more renewable energy plants to be given priority.
But the claims were dismissed by engineers and geologists, “These claims are quite unfair” said Michael Stephenson, director at the British Geological Survey. “The technology behind carbon capture and storage is fully mature. It offers us a genuine solution to some of the problems we face in trying to deal with global warming.”
A government spokesman for the Department of Energy and Climate Change said, “We are committed to meeting our climate change targets in a way that is affordable and provides secure energy to families and businesses. We are considering the role that CCS could play in decarbonization of the UK. But we also need to take government spending into account. CCS had better come down in cost.”
