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

While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!

About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” — a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.

Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

1.Why does the author mention the things that astronauts in space cannot do?

A. To ask us not to take common things for granted.

B. To show they live a difficult life there.

C. To show their life is boring in space.

D. To introduce the topic of the text.

2.NASA offered $ 125, 000 to Anjan Contractor mainly to _______.

A. create some new type of 3-D printer

B. attract more companies to work for NASA

C. help astronauts in space enjoy fresh pizza one day

D. produce pizza in large quantities to earn great profits

3.The biggest challenge that Anjan Contractor is faced with now is probably that _______.

A. he has no money left to go on with his research

B. the pizza doesn’t seem appetizing to pizza lovers

C. he has no way to make pizza that can last for thirty years

D. he cannot make the food container last for decades

4.What’s the best title of the passage?

A. NASA is trying its best to help astronauts eat better

B. Astronauts may soon be able to enjoy steaming hot pizza

C. NASA is working on making pizza for common people

D. A 3-D pizza printer has been used to make pizza

高二英语阅读理解中等难度题查看答案及解析

BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).

However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show – because it's impossible to cry in zero gravity.

Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears don't Flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go—they just stick to your eyes.

In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eye... They just kind of stay there."

Besides making your Vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.

Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait—"When the tears get big enough they simply break free of the eye and float around," astronaut Ron Parise told The Atlantic.

There are lots of small things—things like crying – that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.

Thus, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."

1.What can we conclude from paragraphs 2 and 3?

A. Astronauts are unable to feel sad in space.

B. Astronauts produce fewer tears in space.

C. Tears produced in space flow down more slowly.

D. Tears produced in space don't flow downward.

2.What effect do tears have on astronauts?

A. They cause physical pain.

B. They bring comfort to them.

C. They make their vision clearer

D. They float around and cause trouble.

3.What can the astronaut do to get rid of the tears?

A. Rub his eyes against his helmet to let the tears float forward.

B. Rub his eyes by hand to let the tears float around.

C. Get the tears big enough to fall off of his eyes.

D. Get the tears big enough to break away from his eyes.

4.When of the following can be the best title for the text?

A. In the sky, you can't burp

B. Better life with gravity

C. In the sky, you can't cry

D. No Gravity, no tears
