3 . Many college students turn to ADHD（注意缺陷障碍）medicine during the exam week, which is regarded as “smart drugs” that will help their academic（学术的）performance. The thinking is that if the drugs help students with ADHD improve their focus, they should provide the same benefit for people who don’t have the disorder.

But a new study shows that drugs can actually damage brain function of healthy students who take the drug hoping to boost their intelligence. “It’s not a smart drug which will suddenly improve their ability to understand information they read,” said Lisa Weyandt, a professor at the University of Rhode Island.

To test whether this effect is real or not, researchers organized 13 students to take part in two five-hour study sessions（一段时间）in the lab. The students took the standard 30mg ADHD drugs before one session, and a sugar pill before the other. Students on ADHD drugs did experience an increase in their blood pressure and heart rates. “The medicine was having an effect on their brain,” Weyandt said. The students also showed an improvement in their ability to focus, the researchers found.

However, students on ADHD drugs experienced no improvement in reading comprehension, reading fluency or knowledge reviews, compared to when they’d taken a sugar pill. “We read aloud stories to them and asked them to recall information from the stories, ”she said. “That didn’t improve.”

Worse, the ADHD drug actually harms students’ memory. It’s often misused because people pull all-nighters and they’re tired, and they think it’s going to keep them awake. Maybe it does, but it’s certainly not going to help their academic work. The brain is still developing until the mid to late 20s. It’s important to keep it healthy. There’s also a chance that ADHD drugs could endanger a student’s heart health.

5 . It is in human nature to explore new things. To that end, many countries have been exploring space for many decades, particularly the US, Russia, and countries in Europe.

President Xi Jinping praised the success of the Chang’e 5 mission (使命) in bringing back the country’s first samples (样本) collected from the moon. The whole country is proud of this breakthrough. The Chang’e 5 mission has achieved many significant breakthroughs, including China’s first lunar (月球的) surface sampling, first liftoff from the moon and the first spacecraft with the ability to gather and meet in lunar orbit with samples to re-enter the Earth s atmosphere.

The success of the Chang’e 5 mission marks a conclusion of China’s current lunar exploration project. The successful re-entry and landing of the Chang’e 5 capsule (太空舱) have enabled China to obtain its first lunar samples, marking a new start for lunar and planetary research. With this achievement, China sets a new milestone in space exploration.

No matter how far China goes into space, it always stays true to its original mission-uncovering the secrets of the universe and contributing to human’s peaceful use of space. China is a peace-loving country and will use its achievements for promoting peace around the globe.

China views these efforts as part of the world’s lunar exploration. It chose a different landing site and is promising to share its samples to enrich the planet’s knowledge. Some foreign scientists have shown particular interest. The exploration is not for commercial purposes, but international scientific research. Human beings shall explore the moon together, as it will finally need large projects requiring international cooperation. China will play a leadership role in the international scientific community.

6 . Kamikatsu, a small town in Japan, has shown the world that our garbage has far-reaching effects, and not just on our environment.

The experiment in going zero waste started when the town built a new incinerator 20 years ago. But almost immediately, the incinerator was determined to be a health risk due to the poisonous gases when garbage was burned in it. It was too expensive to send waste to other towns, so locals had to come up with a new plan. Then the Zero Waste Academy was born, which helped perform this plan.

Now Kamikatsu people separate their waste into 45 different categories. But in the beginning, it wasn't easy to convince local people to do all this work, and there was some pushback. Only after that initial education period did most residents come on board.

This is all great news for waste reduction of course, but it has also had some unexpected social benefits as well. Like much of Japan, Kamikatsu's population is aging, and about 50 percent of the locals are elderly. The fact that the whole community takes their trash in to be recycled has created a local action and interaction between generations.

That idea has been purposefully expanded to include a circular shop where household goods are dropped off and others can take them, and a tableware "library" where people can borrow extra cups, glasses, silverware and plates for celebrations.

"The elderly see this not as a waste-collection service, but an opportunity to socialize with the younger generation and to chat. When we visit them, they prepare lots of food and we stay with them for a while, we ask how they are," Sakano, the founder of the Zero Waste Academy, said.

Sakano's ideas are truly revolutionary if you think about it. She's proving that community can be found through handling the stuff we no longer want and need.

7 . If Confucius(孔子)were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and

philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks(缺陷)of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

So the old thinker's ideas are still alive and well.

Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

9 . Wherever we humans go, we leave behind a mess. That goes for space, too. An estimated 500,000 pieces of debris (碎片) litter the Earth’s orbit as a result of man’s explorations of space. Some satellites have been hit by fast-moving pieces of junk. The remains of old rockets can be the size of a bus, while other debris pieces are simply tiny spots of paint.

Today, our species is responsible for the junk dashing around Earth at high speeds, and if we don’t start actively removing the largest pieces, the risk of collisions will only grow worse. “Imagine how dangerous sailing the high seas would be, if all the ships ever lost in history were still floating on top of the water,” says Jan Wörner, ESA director general. “That is the current situation in orbit, and it cannot be allowed to continue.”

It’s almost as if we need a truck to remove all of failed satellites from our orbit. By 2025, the agency plans on launching the world’s first orbiting junk collector, a four-armed robot that tracks down space waste. The first-of-its-kind task, known as ClearSpace-1, will start collecting only a single piece of space junk to prove the concept works. The target in this case is called Vespa, a leftover from ESA’s Vega rocket launch in 2013. This piece of junk weighs roughly the same as a small satellitle and has a simple shape that should make it easy to grab with four robotic arms. Once it’s safely in the arms of the garbage collector, it will then be dragged out of orbit and allowed to burn up in the atmosphere.

In addition, an Australian company, Electro Optic Systems, has received a $ 3.5 million government fund to develop the world’s first laser tracking (激光跟踪) technology. It would replace existing radar (雷达) networks that currently monitor that part of space. The goal is to track small objects with great accuracy.

1. Why does Jan Wörner refer to ships on the high seas?

A．To explain the danger of space debris.	B．To describe the universe’s huge space.
C．To praise man’s explorations of space.	D．To compare the oceans with the universe.

2. Humans plan to handle debris by____________.

10 . Several Eye-Opening Facts about Tears

Humans make three different versions of tears.Basal tears help our eyes move smoothly,reflex tears form in response to irritants(刺激物）such as smoke and dirt,and emotional tears flow when we're sad or over-joyed.Onion tears are obviously of the reflex variety-but what's the irritant?It turns out onions produce a chemical to defend themselves.To cut down on its release,freeze the onion before slicing,then use a sharp knife to reduce the damage to the onion and the release of the chemical.

Crying can be good for you.Some studies have shown a good cry can cause the release of certain chemicals that make us feel better.Crying can also improve people's sense of well being by bringing about social support.On the other hand,crying can sometimes make you feel worse than if you haven't cried at all.One study found that people who tend to cry in general more often feel worse after crying during a movie than people who seldom cry.

According to Entertainment Weekly,the biggest Hollywood tearjerker of all time is Terms of Endearment,about how a family deals with a cancer diagnosis.Number 2:Bambi.According to Merriam-Webster,the term tearjerker first appeared in 1912,which happens to be the same year the Titanic sank.(The movie Titanic is 16th on EW' s tearjerker list.)

In medieval(中世纪）times,crying was perfectly acceptable,even manly.In the Anglo-Saxon poem Beowulf,when Beowulf was killed by a dragon,his soldiers were extremely sad and cried aloud for his death.King Arthur was also known to turn on the waterworks.

Speaking of war,tear gas was banned on the battlefield via the Chemical Weapons Convention of 1993,which was made to happen by Iraq's use of chemical weapons in Iran in the 1980s.That said,American police can still legally use tear gas for crowd control.

1. Why do people have tears while cutting onions?
