The International Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time.

They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon.

Jacqucs has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge 167ft ship, named 'Sea Orbiter', consists of two areas—one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe.

Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player. And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day.

The biggest problem to this giant ship is the cost, which is expected to be over $500 million—per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!

1.Why can’t ocean researchers explore the deep oceans for a long time?

A. Because they can’t stand the high water pressure.

B. Because it’s too cold in deep ocean.

C. Because time for experiments is too limited.

D. Because it’s dangerous to observe the sea life.

2.The underlined word "circumvent" probably means________.

A. fly away    B. get around     C. travel through     D. move into

3.From the fourth paragraph we can learn that________.

A. Jacques intends to design the ship mainly for sightseeing and traveling

B. living a comfortable life helps to do the ocean research quickly

C. it’s much more expensive to eat freeze-dried food

D. researchers on Jacque’s ship will live more comfortably than astronauts

4.Which of the following would be the best title for the text?

A. Sea Orbiter—the ship of the future

B. A new way to explore the deep oceans

C. A great architect—Jacques Rougerie

D. Travel around the globe in Sea Orbiter

Sophie dreams of walking in __________ outer space like __________ astronaut one day.

高二英语单项填空中等难度题查看答案及解析

Scientists are using robots to study the health of waters in and around Venice，Italy．The robots are designed to act like fish，other underwater creatures and plants．The scientists are working with several universities and research centers as part of a group called subCULTron．The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation(创新)in Europe．The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon(潟湖)．

SubCULTron．a collective artificial intelligence project，plans to create the biggest shoal (鱼群)of robot fish in the world．The project’s aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items．

Alexandre Campo，a computer scientist，says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together．The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water．

One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don’t work underwater．Instead，the robots can use sonar(声呐)and an electric field．

Another problem was charging batteries．The robots come up to the water’s surface and stay near a boat or a power station to charge without any electrical cables．Besides，how to be waterproof, especially for some key pads of the robots，was really tough．Fortunately, a special mixture has been created to be pinned on the robot，which successfully stands the test of water．

The health state of the lagoon is pretty good．There are no industrial polluters，and the city now has a modern sewer(污水管) system．It’s not like before when all the waste flushed directly into the water．The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”．

1.What can we learn about the project in Paragraph l?

A. Its researchers are all from universities．

B. The European Union has financially supported it．

C. It uses robots to clean the waters in and around Venice．

D. It is aimed to support science and innovation worldwide．

2.What can we infer according to Alexandre Campo?

A. Scientists have got an idea for robots from the animals．

B. The robots are working separately to perform their tasks．

C. SubCULTron is to turn human abilities into hi-tech items．

D. The health state of the lagoon has greatly improved recently．

3.The underlined word “they” in the last paragraph probably refers to“__________”．

A. scientists　　 B. animals

C. robots　　 D. humans

To be clear, plastic bags are rightly thought of as a threat that's harmful to human health. According to the National Resources Defense Council, over a decade ago, the average American family took home almost 1,500 plastic shopping bags a year, filling our cabinets, kitchen drawers, and landfills (垃圾填埋场). Today the numbers are slightly better: According to National Geographic, as of 2018, shoppers in the United States use almost one plastic bag per resident per day.

This is not a story on the evil of plastics, but on whether the reusable bag can justify its existence. Although more environmentally friendly than traditional single-use plastic bags, reusable bags, depending on what they are made of, are more energy-intensive (耗能) to recycle.

According to a report by the United Nations Environment Program, “depending on what they are made of, reusable bags might have to be deconstructed in a costly recycling process to separate the different materials. As a result, in many cases, reusable bags are not recycled." That means despite the best intentions, millions of reusable bags designed to replace the need for traditional plastic shopping bags, will also end up in landfills.

Another point to consider, not all reusable bags are equal in terms of their recyclability. There are a wide range of reusable bag options on the market, and reusable bags tend to be made of more than one material to give the bag added reinforcement (耐用) and added street fashion. On a life cycle basis, stronger, heavier bags-no matter what material they are made of-will have a more severe environmental effect. That's because heavier bags use more resources to produce as well as distribute.

Just like plastic bags did, reusable bags multiply rapidly. Used for promotional (促销的)purposes and marketing of all kinds, reusable bags' growing popularity means bags that have been used very little (or not at all) can be found piled in streets, in garbage cans in city parks, and basically everywhere. Therefore, consumers have come to see them as disposable, defeating their very purpose.

In the end, the best practice for reusable bags is to have no half measures: Either use them all the time or don't use them at all. Using a reusable bag once or twice, and then throwing it away, doesn't do the environment any favors.

1.What can we learn from the passage?

A.Plastic bags are refused by environmentalists.

B.Shops in America have limited the use of plastic bags.

C.The need of strong and fashionable reusable bags is more than the supply.

D.Reusable bags demand more resources to produce and recycle than expected.

2.The words “very purpose" in Paragraph 6 refer to the intention of __________.

A.being left in landfills

B.being used as much as possible

C.replacing plastic bags

D.promoting goods on the market

3.Which of the following would be the best title for the passage?

A.How to Recycle Reusable Bags

B.Disadvantages of Plastic Bags

C.Reusable Bags? Think Twice!

D.Plastic Bags, Less Popular?

4.Which of the following shows the development of ideas in the passage?

I: Introduction　　 CP: Central Point　　 P: Point　　 Sp: Sub-point (次要点)　　 C: Conclusion

A. B.

C. D.

Bollworms are a traditional threat to cotton crops．Young ones feed on the boll, the part of the

cotton plant that contains the seeds．

A bacterium known as Bt is able to kill bollworms and some other pests．Bt is short form for Bacillus thuringiensis．It was discovered in the early twentieth century．Farmers began using Bt as a natural pesticide（杀虫剂）．

Then，in the 1990s，researchers found a way to grow cotton plants that contain a Bt gene．The genetically modified cotton plant produces toxins that kill bollworms．Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton．

Cotton bollworms also attack other crops．But scientists in China recently reported that Bt cotton may help suppress bollworm in other crops growing nearby．

The study involved crops grown in six provinces of northern China between 1992 and 2008.The study area contained three million hectares of cotton and twenty-two million hectares of corn，peanuts，soybeans and vegetables．

The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its presence on other crops．And that reduction，they say，may decrease the need for insecticide use in general．

But the researchers also pointed out concerns．They say bollworms could develop resistance to the cotton plants designed to resist them．And they noted that insects called mirids have become “key pests” of cotton in China．They said this is because of a decrease in pesticide use made possible by Bt cotton．

The researchers say they do not believe that Bt cotton alone can solve all insect problems．Instead，they say farmers in China should consider it just one part of pest management systems．

44．What is Bt in this passage?

A．It's a kind of hi-tech invention．      B．It's a natural bacterium．

C．It's a kind of pest．                    D．It's a man-made pesticide．

45．Bt cotton has all the advantages EXCEPT that ________．

A．it resists bollworms

B．it does good to other crops growing around

C．it reduces the use of insecticide

D．it helps to develop new insects

46．The underlined word “ones” in the first paragraph refers to ________．

A．bollworms             B．cotton crops          C．cotton seeds        D．pests

47．From the passage，we can infer ________．

A．farmers around the world are now growing a large area of Bt cotton

B．researchers are probably now searching for new ways to solve other cotton problems

C．bollworms could not exist in Bt cotton any longer

D．Chinese scientists found the way to grow Bt cotton
