Life as an astronaut has various unique attractions. This can include experiencing weightlessness and looking back at Earth as a pale blue dot. Food is not among them. Space travelers over the years have become used to certain foods such as freeze-dried ice cream and liquid salt and pepper. Now, the menu is set to be augmented, with the first space-grown lettuce (生菜) found to be as safe, nutritious and fresh as the Earth-grown variety.

Gioia Massa of NASA Kennedy Space Center is the lead scientist on the lettuce-growing project. She said that growing food in space could be wonderful for astronauts on missions lasting more than one month.   “If you store packaged food for a long time, not only will the flavour and nutritional quality decrease, but the vitamins will degrade. After eating such food, astronauts’ intake of nutrition is not ensured,” she said. “Besides, for them, there may also be psychological benefits of growing and looking after plants.

Lettuce has been grown in batches (分批) onboard the International Space Station (ISS). The vegetable production system is known as Veggie. It is composed of plant pillows (sealed units containing ceramic soil), LED lighting and a watering   system that allows astronauts to inject water through a tube. The lettuce crops grow undisturbed for 33 to 56 days before being harvested and eaten, or deep-frozen and returned to Earth for chemical and biological analysis.

The space-grown lettuces are similar in make-up to Earth-grown ones but they have higher levels of bacteria (细菌), possibly due to their growth in a warmer, more humid (潮湿的) and closed-air system. But they are not found to carry any harmful bacteria.

NASA is now enlarging the range of produce grown onboard the ISS. It will be quite some time before any vegetables can be transformed into a dish, however. “While we have nowhere to cook up there now, we can look forward to more things that taste fresh,” Massa explained.

1. What does the underlined word “augmented” probably mean in Paragraph 1?
A.Enlarged.
B.Engaged.
C.Reduced.
D.Measured.
2. What do we know about growing space-grown lettuce?
A.It’s flavor and nutritional quality decline.
B.It is terrible for astronauts on missions.
C.It can contribute to astronauts’ mental health.
D.It will make sure the astronauts’ intake of nutrition.
3. What can we infer from the text?
A.Lettuces will be grown in batches onboard.
B.The vegetable production system consists of three parts.
C.It will take at least 56 days to harvest the space-grown lettuce crop.
D.Thanks to growing environment, the space-grown lettuces don’t contain any harmful bacteria.
4. What does Massa mainly intend to explain in the last paragraph?
A.The difficulty in growing produce onboard.
B.The necessity to enlarge the space onboard.
C.The desire to enjoy cooked vegetables onboard.
D.The expectation to enrich the variety of produce grown onboard.

【推荐1】My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He’s a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they’re also pleased to see him alive.

Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom’s best friend. And Injun Joe is the bad man of the story.

The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it’s still read and loved by people all over the world today. And although it’s only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it’s thought to be one of the greatest books in American literature. Go on—read it! I know you’ll enjoy it, too.

【推荐3】A primary school in County Cork, Ireland, has decided to do away with all homework for the entire month of December, replacing it instead with acts of kindness.

For the third year in a row, students at Gaelscoil Mhíchíl Uí Choileáin will not have any homework for the month of December. Instead, they are being asked to undertake acts of kindness for friends, family and the community — and to record these in a special “Kindness Diary” which each student will fill in daily and then get signed by their parents.

“Building on the overwhelming success and positivity of last year’s Gratitude Diaries, when children and their families documented the small things they were grateful for in their lives, this year they are asked to undertake little acts of kindness that could make a big difference in somebody’s life,” Vice Principal Íde Ní Mhuirí said.

The school suggests doing something nice for an elderly neighbor, or performing an act of kindness for a relative or friend who may be feeling lonely, but the act can be anything as long as it brightens someone’s day.

Alongside this Kindness Diary initiative (倡议), there will be a kindness bucket in school, where the children can place kind observations about their peers which will boost the self-respect of those around them. Each Friday morning at the gathering a random selection of these observations will be shared to stress how small acts and kind words can make huge differences in somebody’s life. And finally, each class will put their heads together and come up with a class-wide project which can help the community.

“In this world, consumed by social media, where our young people are constantly experiencing pressure, there is no better way to show them the way forward in the world than by practicing kindness,” Íde Ní Mhuirí said.

1. What does the school require the pupils to do this December?
A.Keep a diary of their daily lives.B.Show kindness to someone else.
C.Express their gratitude to others.D.Finish their homework on time.
2. What Does the Vice Principal think of the Gratitude Diary?
A.It needs improving.B.It ended in failure.
C.It is quite satisfactory.D.It will be continued.
3. Why are the students encouraged to make kind observations about each other?
A.To monitor their behaviour.
B.To evaluate their moral character.
C.To share their ways of dealing with stress.
D.To give them a sense of pride and importance.
4. What’s the best title for the text?
A.Homework or Acts of Kindness?
B.How to Make a Big Difference in Life?
C.Irish School Relieves students of Homework.
D.Irish School Replaces Homework with Acts of Kindness.
