1 . Buying furniture is easier than ever. You can even order a new table and chairs online without ever leaving home. But did you ever think about how furniture is made? The process begins with trees but now researchers have found a better way: growing it in a lab instead of a forest. Instead of cutting down trees and adding to deforestation, Velasquez-Garcia said, “If you want a table, then you should just grow a table.”
The research group found a way to actually grow plant tissue (组织) — wood and fiber — in a lab that is similar to the way cultured meat is grown. While there is still a long way to go to actually grow a table, the team was able to grow structures from cells from zinnia leaves.
Making furniture and other items from biomaterials could eliminate cutting down trees in forests. “The way we get these materials hasn’t changed in centuries and is very inefficient,” said Velasquez-Garcia. “This is a real chance to avoid all that inefficiency.”
There are other benefits to using lab wood too. Lab grown wood can be handled to take on any shape — like 3 D printing — so it may be possible to build a table without glue or screwing parts together.
Beckwith, a mechanical engineering PhD student, was inspired by a visit to a farm to try to make land-use more efficient and environmentally sound. “That got me thinking: Can we be more strategic (战略上的) about what we’re getting out of our process? Can we get more yield for our inputs?” she told MIT News. “I wanted to find a more efficient way to use land and resources so that we could let more farmlands remain wild, or to remain lower production but allow for greater biodiversity.”
Today, the two largest uses of trees are to make wood products and paper. When new biomaterials become readily available, forests will lose their economic value and will be preserved for their environmental, health, and recreational value. These researchers, like Velasquez-Garcia, are speaking for the trees.

2 . We were on our way! In Wyoming we would have a new home. It was 1980 and my husband Gary and I were driving to Wyoming with our kids. After driving all day, we were hungry. So we stopped at a restaurant to have dinner.
After the dinner, we were on our way again. Suddenly our car hit ice on a bridge. As soon as the car started to slide. Gary touched the brakes (刹车) but failed to control the car. We were thrown from side to side against the guardrails (护巴). It took some time before we slid to a stop, but unfortunately our car was totally destroyed.
Only minutes later, a car stopped by and the driver asked how he might help, With his help, my husband was able to have our car taken to Rapid City. Then he drove us to a hotel in the city. He made sure we were safe before he said good night and left. The next morning, the driver returned and drove us to find our car so that we could take back our valuables. He lost at least half a day of work, all for a family he had never met and would never see again.
With no car, our family finally arrived in Gillette, where we had no friends. Though we were a little lonely, we all felt lucky and thankful to the amazing stranger whose service made such a difference to our family.

5 . Lifestyle Changes to Make You Healthier and Happier
All people want to stay healthy and happy, but most of our focus is on sick-care, not healthcare.
Food for health
Everyone knows we should eat certain amount of fruit and vegetables a day,
Do exercise
Getting less than five hours’ sleep a night doubles the risk of death from heart disease, according to a study, and other studies have shown that it speeds up ageing. And it plays a big part in our mental health, too.
Friends for life
A.Research shows 15 minutes’ exercise a day could add 3 years to your life. |
B.Here’s how you can start to improve your health and happiness. |
C.Friendships actually change our body chemistry. |
D.yet only 28% of adults are hitting this target. |
E.Sleep well |

9 . Can you imagine that there are a huge number of tiny waste pieces in the Arctic (北冰洋的) sea ice? Because of the waste pieces,30,000 kinds of animals are in danger. It’s true that one person’s acts alone can’t help the planet. But each one of us can find ways to make our contributions.
In the home, we could try not to waste foods. Use a digital meal planner to get a right amount of food so that everything we buy and cook gets eaten. Learn how to store foods to keep them fresh longer. Be sure to use proper ways to keep our home warm. For example, we can replace old windows with energy-saving ones.
At the store, we could green our habits. Buy reusable plates, but not single-use ones. Buy home tissue (纸巾) not made of materials which may lead to destruction (破坏) of forests. Buy glass cups instead of paper ones.
In the community, we could help keep its plants healthy. Take part in tree-planting projects or grass-cutting activities to help plants grow well.
Our actions alone can’t save the planet, but the above ways and habits can help.
1. What puts so many animals in danger?A.Cold ice. | B.Waste pieces. | C.Bad weather. |
A.To avoid wasting foods. |
B.To cook delicious foods. |

B.That can be used again. |
C.That can be thrown away. |

10 . We use our middle names when filling out official papers, and when we write our initials (姓名的首字母) on something. But except that, we don’t use them every day. So why do we even have middle names in the first place?
Some people might answer, “It’s so my mom has three names to shout at me, so I know I’m in trouble.”
But there is history behind it, and it dates back to ancient Rome. At that time, people had three names, a personal name, a family name, and another name which showed what branch of family you were from. The more names you had, the more respected you were by others.
This tradition of names spread over to Western cultures in the 1700s.Aristocrats (贵族) would give their children long names to show their high place in society. Spanish and some other cultures would give their children names from their parents’ previous generations to be able to keep track of the child’s family tree.
But the way we use middle names today started in the Middle Ages when Europeans named their children with the given name first, baptismal (洗礼的) name second, and family name third. The tradition was spread to America as people started to go overseas.
Today, some people don’t even have middle names, some prefer to be called by their middle name, and some never even use theirs. But, just feel lucky that we don’t need to keep track of our family tree like some aristocrats used to and end up with 38 names.
1. When would we use middle names?A.When calling our friends. |
B.When writing to our parents. |
C.When filling out official papers. |
