Garbage sorting is vitally to our life and environment. For one thing, garbage sorting can help separate the recyclable waste from the rest. To reuse and recycle this kind of waste are to save resources to a large extent, that also contributes to the environmental protection. For another, sorting waste is a meaningful deed.

If everyone takes an action, it can save money and time for a city get rid of waste. Take myself as an example. I used loads of paper every year, so with waste paper packing up, I can sell it and earn some pocket money. Also you can make a contribution to the environmental protections.

In a word, we should bear on mind that garbage sorting will bring profound rewards to our society.

Lantern Festival marked the final day of the Chinese Lunar New Year. It has been an important festival1.the Western Han Dynasty.

In ancient China, often marriage2.(decide)by parents or even the government. During some periods marriage policies went to extremes.

However, extreme policies to force people to get married were rare, and young people still had certain3.(free)to get married with people they liked, rather than being4.(complete)manipulated by their parents or government. Ancient Chinese had milder ways to encourage people to find a spouse, such as fairs and meetings during festivals.

Lantern Festival is one of the festivals that provided ancient Chinese single young men and women a chance5.(meet)and get to know each other. On the night of that day, 6.(marry)men and women would meet at the flower fair and lantern-decorated street.

Romance often happened, 7.not all of these stories ended happily.

Ouyang Xiu described a woman's longing for the man she met during Lantern Festival in his poem Yuan Xi. It8.(go)like this: "Last lantern festival, the flower fair9.(decorate)with lights was daylight bright. We met after dusk when the moon rose behind willow trees. This year the moon and lanterns are still10.same, yet you are not here anymore. I am sad, with tears shed on the sleeves of my spring coat.”

Never Too Late to Be What You Want to Be

The first day of school our professor introduced a little old lady, Rose, to us.

We became instant friends. Every day for the next three months we would leave_________together and talk nonstop. I was always listening to this “time machine" as she_________her wisdom and experience with me.

At the end of the semester we invited Rose to make a_________to our football team. I'll never forget what she taught us. As she began to deliver her prepared speech, she _________her note card on the floor. A little_________she simply said, “I'm sorry. This whiskey is killing me! I'll never get my speech back_______so let me just tell you what I know." As we laughed she_________her throat and began: “We do not stop playing_________we are old; we grow old because we stop playing. There are only four secrets to staying_________, being happy, and achieving success. You have to laugh and find humor every day. You've got to have a dream. When you____________your dreams, you die. We have so many people walking around who are____________and don't even know it! There is a huge difference between growing older and growing____________.

What Secrets Your Voice Reveals About You

So, have you ever stepped back and wondered what your voice sounds like to other people?1.. And it turns out, it says a lot about us.

·Your voice hints at how social you are

2.. Extroverts tend to talk loudly, quickly, and excitedly. Introverts tend to speak quietly and more slowly. So, if you're that loud person at a party, you'll probably find that all eyes are on you, whereas introverts won't likely be at that party at all.

·Your voice says something about your height

This may sound strange, but if people close their eyes and hear you speak, they can probably tell if you're tall or short.3., whereas shorter people tend to have a higher voice. This is true for both men and women.

·4.

If you've noticed a lot of changes in a person's voice—the pace at which they talk, the tone and pitch of their voice, or whether their voice has become quieter—they may have Parkinson's disease. These changes can happen in the voice due to the tremors(震颤)that a patient would be experiencing.

·Your voice can tell how successful you are

Successful people's voices tend to be of a lower, warmer tone. Their words come out evenly, and their vocal cords won't be tight.5., but not so loudly that they're unpleasant to listen to.

A.Taller people tend to have a deeper voice

B.Your voice can tell others about your health

C.Your voice reveals how professional you are

D.They'll speak loudly enough to make themselves heard

E.A confident person will have a smooth and steady tone

F.Specifically, people can tell whether you're an extrovert or introvert

G.Your friends and family can probably identify you just by the sound of your voice

    A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need.

Now a team of scientists has repurposed living cells—scraped(刮落)from frog embryos—and assembled them into entirely new life forms. These millimeter-wide “xenobots” can move toward a target, perhaps pick up a payload(like a medicine that needs to be carried to a specific place inside a patient)—and heal themselves after being cut.

“These are novel living machines,” says Joshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research. “They're neither a traditional robot nor a known species of animal. It's a new class of artifact：a living, programmable organism.” “We can imagine many useful applications of these living robots that other machines can't do,” says co-leader Michael Levin, “like searching out nasty compounds or radioactive contamination(污染物), gathering microplastic in the oceans, traveling in arteries(动脉)to scrape out plaque.”

People have been manipulating(操纵)organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years—copying the body forms of known animals. But this research, for the first time ever, “designs completely biological machines from the ground up," the team writes in their new study.

Many people worry about the implications of rapid technological change and complex biological manipulations. "That fear is not unreasonable,” Levin says. "When we start to deal with complex systems that we don't understand, we're going to get unintended consequences.” “If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules,” says Levin. Much of science is focused on "controlling the low-level rules. We also need to understand the high-level rules." In other words, “this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences,” Levin says.

1.What do we know about the “xenobots” from Paragraph 2?

A.They need to be carried to a specific place.

B.They're capable of self-healing after injury.

C.They are scraped from some new life forms.

D.They can remove an object to another place.

2.Michael Levin thinks these living robots can __________.

A.recycle microplastic in the oceans

B.take in nasty compounds

C.programme other organisms

D.take away the plaque in arteries

3.What does the underlined sentence(in Paragraph 4)probably mean?

A.People never created these biological robots in history.

B.These machines were copied from the very beginning.

C.The research is completely carried out on the playground.

D.Organisms have been developed since agriculture.

4.What can be inferred from the last paragraph?

A.This study is bound to bring about panic in public.

B.People boycott employing rapid technological change.

C.Science is focused on controlling the low-level rules.

D.Some study is likely to contribute to unexpected results.
