However exciting space travel sounds, astronauts must still suffer with bad food. Now, food in space has to be dehydrated ( 使 脱 水 ) or pre-cooked and stored. This means astronauts aren’t really eating fresh food.

New technology may change this. Scientific American reports that a specially-designed oven will be sent into space this autumn with NASA’s NG-12 cargo (货物) mission (太空飞行任务).

Far from the common vacuum-packed (真空包装的) meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.

Why aren’t they baking cookies in space already? For one thing, there’s the risk of a fire. Engineers also have to overcome the challenge of microgravity ( 微 重 力 ), which prevents heat from circling inside ovens the same way it does on Earth.

Astronauts will still have to wait a while before they can have their cookies, though. After baking, the results will be sent back to Earth for safety testing. If successful, this will be the first oven to bake food in space.

“I believe ... that will be game-changing for both science and astronauts,” food technology researcher Maeena Naman Shafiee told Scientific American.

One of the main driving forces behind this project has been NASA’s 2018 research into the effects of “confinement (封闭) and isolation (隔离)”. Unlike on the International Space Station (ISS), astronauts traveling out of Earth’s orbit (轨道) may not be able to speak to their loved ones on future missions, which could lead to negative feelings.

It’s hoped that the chance to bake and sense familiar smells can bring joy to crews (宇航人员).

“Is the ISS going to smell like fresh-baked cookies? We don’t know,” said NanoRacks’ communications manager Abby Dickes. “But that’s a feeling we all know and love ... that will make someone feel at home.”

Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel. Astronauts have already grown plants aboard the ISS.

With commercial ( 商 业 的 ) space travel now being planned, who knows what other developments may surprise us in the future?

1.What can the new technology help astronauts to do in space?

A.Enjoy fresh cookies.

B.Store more food.

C.Quickly prepare food.

D.Cook many different kinds of home-made meals.

2.Why is it difficult to bake cookies in space?

A.It’s difficult and costly to send food into space.

B.Microgravity stops food from staying in one place.

C.Baking cookies in space would pollute the spaceships.

D.It is hard to heat food properly because of microgravity.

3.What was the main purpose of the cookie project?

A.To improve astronauts’ health.

B.To make improvements in space travel.

C.To encourage more people to travel to space.

D.To make space travel more comfortable for astronauts.

While astronauts in space get to do many exciting things, they miss out on ordinary things that we will 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 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 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 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.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

2.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

3.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

Astronauts traveling in space meet forms of radiation that are uncommon on Earth. Some of this radiation has been shown to be harmful to human health. It is linked to cancers and heart problems. Yet a new American study suggests the radiation does not shorten astronauts' lives.

Researchers studied nearly 60 years of health records and other data about male astronauts from the United States. They then compared this data with information about a group of men who are in good health, richer than most Americans and receive good health care-professional athletes. The study found that neither group has higher rates of dying at a young age. In fact, both groups generally live longer than other Americans.

Astronauts are usually well-educated, earn more money and are in better physical condition than the average American. Some earlier research has linked being an astronaut to a lower risk of early death, the researchers noted. The findings were reported in the publication Occupational & Environmental Medicine.

Much of the existing research on mortality rates in astronauts has not yet explored the mental and physical demands of this job. There also has not been a lot of research on whether astronauts show what is known as the "healthy worker effect". This effect leads people with employment of any kind to have fewer medical problems than people who are unable to work, said Robert Reynolds.

Reynolds said, "The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all. To do this, we need to find a group that is comparable on several important factors."

1.How did researchers carry out their study?

A.By doing interviews. B.By analyzing some factors.

C.By comparing different data. D.By doing experiments in the lab.

2.What can we learn from the text?

A.All radiation is harmful to human health.

B.Athletes tend to be poorer than most Americans.

C.Healthy worker effect makes working people healthier.

D.Research has explored the mental and physical demands of being astronauts.

3.What can he inferred from Reynolds' words?

A.They are determined to face the challenge.

B.The research is almost impossible to conduct.

C.Several important factors hold back the research.

D.Astronauts are as healthy even they haven't been Astronaut.

4.What can be a suitable title for the text?

A.Astronauts----Healthy or Otherwise

B.Astronauts Are as Healthy as Athletes

C.Radiation Affects Astronauts' Health

D.Astronauts---- Well-Educated and Earn More

China’s first taikonaut Yang Liwei landed safe in the Shenzhou V capsule in Inner Mongolia. He was in space for twenty-one and a half hour. Yang Liwei took many photographs of our planet.“Our planet is such beautiful,”he said.

When Yang Liwei took off from Jiuquan ,China became the third nation to send a man in space. Yang is 431th person to travel in space, include astronauts from 32 countries.

As he was in space, Yang spoke to two astronauts aboard the International Space Station. Edward Lu, whose parents were born in China, speaks to Yang in Chinese during his flight. Manlenchenko said,“It’s a great work by people from China.”

Many countries sent messages of congratulations. Sean said Yang’s space flight was an important history achievement.
