Landfills are where most of the world’s plastics end up and a fair amount of it ends up in the world’s oceans. But a new British recycling firm wants it to end up here.

There is a great demand right now for recycled material. There’s a great deal of interest in getting recycling into the plastics industry specially, and so we are really going to further the ability to get plastic into the circular economy.

The firm called Recycling Technologies is breaking down plastic, then turning it into fuel oils or raw material to make new plastics. Basically, currently all we do is we make a hydrocarbon soup and then we take the materials out at different temperatures, so the higher temperatures, the waxes separate out, then we cool it a bit more, and the heavy oils then we call it, a bit more the light oils, and then the rest comes out. It’s naphtha, the gases that don’t condense (凝结) out. We actually use the fuel for the process. Their process is creating a heavy fuel oil that works for marine vessels (海洋船舶). We call it a clean material, because it has very little sulfur in it, in fact almost none, which certainly also fits with the new regulations for marine fill, where they’re asking for much lower sulfur around the world. So it’s a very valuable product.

Right now, the firm is recycling about 7,000 tons of plastic a year, but says it can quickly increase. We are designing to a four-day installation (装置). We will basically come in six ice-free containers which will stand on end, fixed together, and we plug in play mode and the aim is to be up and running within four days. So this is definitely not a refinery (提炼厂) concept.

This is much more a piece of stand-alone industrial equipment. The company has set the ambitious goal of selling 1300 of their recycling units around the world during the next decade, and expect they will be able to recycle 9 million tons of plastic each year.

1. From the last sentence of paragraph1 we know that the British recycling firm ______.
A.wants the plastic waste to be kept in landfill
B.wants the plastic waste to be poured in the ocean
C.thinks the plastic waste should be recycled
D.thinks the plastic waste should not be used any more
2. What can we infer from the third paragraph?
A.Plastic can break down by itself.
B.Temperature plays an important role in breaking down plastic.
C.Plastic will be broken down into three matters.
D.Light oil is thought to be clean because it contains little sulfur.
3. Which statement can best describe the four-day recycling installation?
A.It is quite new and difficult to accept.
B.It’s complex and skeptical.
C.It’s helpful and promising.
D.It’s dangerous and unpredictable.

文章大意:本文为一篇说明文。主要讲述了太阳能做饭这一现象,并介绍了三种太阳能炉子的构造和特点。

【推荐1】Millions of people around the world cook their food over smoky fire every day.It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.

Solar cooker, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in seventeen sixty-seven. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.

There are three kinds of solar ovens.The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amonts of food.

The second kind of solar oven is a panel cooker. It includes several flat walls, or panels that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars.

The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.

You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

1. What is the main purpose of the author in writing the passage?
A.To tell the readers how to make solar ovens.
B.To advertise the solar ovens.
C.To give the readers brief introduction of solar ovens.
D.To help readers to save cost on fuel.
2. According to the passage we can conclude that ______.
A.panel cooker is the cheapest oven of the three
B.panel cooker is easy to make
C.box cooker is easy to make
D.box cooker is the most effective oven
3. If you have much food to cook, you’d better choose     .
A.a box cooker
B.a panel cooker
C.a parabolic cooker
D.a paper cooker
4. From the passage we know that     .
A.solar cookers are dangerous to use
B.solar cookers don’t burn while cooking
C.solar cookers cost less than other cookers
D.Swiss often use solar cookers while cooking

文章大意:本文为一篇新闻报道。本文介绍了中国的神舟12号在太空完成了既定空间站太空任务,三名宇航员成功返回地球,展示了中国在太空科技领域的力量。

【推荐2】A spacecraft carrying Nie Haisheng,Liu Boming and Tang Hongbotouched downsafely in the Gobi Desert in Inner Mongolia today (Sept.17) at 1:34 a.m. EDT (1:34 p.m. Beijing time) today, bringing the historic Shenzhou 12 mission to an end.

Shenzhou 12 launched on June 16 and arrived seven hours later at Tianhe ( “Harmony of the Heavens” ), the core module of China’s Earth-orbiting space station. The Shenzhou 12 crew, commanded by Nie, spent 90 days aboard Tianhe, staying aloft about three times longer than any previous Chinese crewed spaceflight.

Shenzhou 12’s return to Earth was a multiday affair. The spacecraft detached from Tianhe Wednesday (Sept.15) at 8:56 p.m. EDT, according to a statement released by the China Manned Space Engineering Office (CMSEO). Shenzhou 12 then performed a rendezvous test with Tianhe, which was complete by 1:38 a. m.EDT Thursday (Sept.16), CMSEO officials said in another update.

During their time in orbit,the Shenzhou 12 astronauts snapped some amazing photos of Earth and carried out a variety of scientific experiments. They also performed two spacewalks designed to help get the 54-foot-long (16.6 meters) Tianhe fully up and running and ready for future visits, which will be frequent over the coming months.

For example, China is expected to send the robotic Tianzhou 3 cargo spacecraft toward Tianhe around Sept.20. And the next crewed mission to the module, the six-month-long Shenzhou 13, is apparently scheduled to launch in mid-October. (Exact target dates are hard to come by with Chinese missions, because the nation tends not to announce many details of its spaceflight plans in advance.)

1. The underlined part “touched down” in the first paragraph probably means ________.
A.landed successfully
B.launched on time
C.took off on schedule
D.updated around the clock
2. According to the passage we know EDT is ________.
A.12 hours ahead of Beijing time
B.8 hours ahead of Greenwich Mean Time
C.12 hours later than Beijing time
D.8 hours later than Greenwich Mean Time
3. What is the main purpose of the mission to Tianhe?
A.To repair the parts that went wrong.
B.To carry out two space walks.
C.To send the robotic Tianzhou 3 cargo spacecraft.
D.To get China’s Earth-orbiting space station ready and running.
4. In which section can we most possibly read this text on a website?
A.Geography.
B.News.
C.Health.
D.Environment.

【推荐3】When you’re not at home, many worries may start to crowd your mind. Did I turn the coffee maker off? Did I lock the door? Are the kids doing their homework or watching television?     1    

A smart home is a home with a communication network. This network connects devices, such as lights and TV sets, and allows them to be controlled from far away through electrical wiring, mobile phone communication or WiFi over the Internet.

    2     It can help keep your room at a certain temperature. It can record what happens inside the home and send the video to your phone. When you are on vacation abroad, you can use a smart home controller to switch on or off the electricity when necessary. Some smart homes can receive a visitor, allowing him to come in and offering him a drink.     3     Besides, smart homes are easy to fix.

Most smart home technology and devices are wireless and can be setup with a minimum of tools, using only the guiding information. When a problem appears you can deal with it yourself without paying a professional.

    4     It can be rather expensive to own the technology and the devices. Also, because the smart home system allows its owner to get home information from anywhere, it leaves the home easy to be attacked by hackers, who may secretly use or change the information in the system.

Now, many scientists are excited at the future of smart home technology. Imagine being able to get fashion advice from your mirror, or receive food shopping suggestions from your refrigerator.     5     Whatever it is, one thing is for sure — smart home technology will change the way we live and work.

A.Is there anyone else breaking into my house?
B.They can even feed the cat and water the plants.
C.With a smart home, you can quiet all of these worries.
D.However, for home-users, the smart home technology is far from perfect.
E.Therefore, many people think the smart home technology has some disadvantages.
F.Meanwhile, others worry those smart devices will make people lazier and lonelier.
G.Many people may consider owning a smart home, making life much more convenient.
