Eco-friendly Car Racer

Can you image a car racer is so eco-friendly that its tyres are made from potatoes, its body is created from hemp (大麻) and rapeseed oil and it runs on fuel made from wheat and sugar beet? The one-seater racing car called Eco One is built by experts from Warwick University, who hope that Eco One will be adopted by the automotive industry. It is sold at $ 51,000.

Pollution-sensitive Dress

Don’t be caught outside unaware of pollution levels in the air. The pollution-sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly. This dress – which is actually quite pretty – looks like you pull it from the bottom of the dirty laundry pile when the air is dirty. It might protect your health by advising you to stay indoors for the day, but it won’t do you any favor if you’re meeting with clients.

Eco-friendly Umbrella

Traditional umbrellas come with a fixed surface. Although it is changeable, you cannot replace it easily. This eco-friendly design is more flexible. It is actually only an umbrella skeleton without any surface, which can be folded, so you can put anything such as newspapers, plastic bags or whatever you want to serve as the protecting surface.

Eco-friendly Moss (苔藓) Carpet

It is said that walking on fresh grass increases your blood circulation. The Moss Carpet, created by Nguyen La Chanh, looks at getting the grass to your feet. The mat includes ball moss, island moss and forest moss. The humidity (湿度) of the bathroom ensures that it grows well. And that’s why you need to place it there and not anywhere else.

It took 100 years, but finally, scientists, from CalTech, MIT and the LIGO Scientific Collaboration, proved Albert Einstein's theory that gravitational(引力的) waves exist. The waves were predicted as part of Einstein's General Theory of Relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the Universe. For example, two black holes crashing into each other.

What are these gravitational waves? Well, imagine throwing a rock into a pond. When the rock hits the flat surface of the water, it creates ripples or waves. Space time is like the surface of the water. So that means gravitational waves are like the ripples moving out from where the rock hits the water. It might be hard to understand, but those gravitational waves expand and contract space and time as they move through space. And when they get to the Earth, the waves pass through, and contract and expand the planet as the wave goes by.

It was Einstein who said these gravitational waves should be observable. But these are not huge waves. They are very, very small, which is why it took so long to find them. You cannot see them with your eyes. They are smaller than the size of an atom.

How did the scientists find them? For years, scientists have been watching two black holes in another galaxy faraway with the help of the Laser Interferometer Gravitational-Wave Observatory. The two were spinning around each other, moving closer and closer together. When they finally crashed into each other, it was with such power and force, that gravitational waves rang throughout the universe, like a giant bell. Those waves, traveling at the speed of light, finally reached the Earth, some 1.3 billion years later. They are the same waves that the scientists announced this past week.

The National Science Foundation tweeted that each of the black holes was thought to be 29 to 36 times the mass of our sun. So, what does this discovery mean? Abhay Ashtekar, a Penn State physicist, who was not on the discovery team, said: "Our understanding of the heavens changed dramatically."

1.According to the 1st paragraph, we can learn that_______.

A. gravitational waves were part of Einstein's General Theory of Relativity

B. scientists proved that gravitational waves existed 100 years ago

C. gravitational waves were the theory of the physics behind the universe

D. gravitational waves result from two black holes crashing into each other

2.From the passage we can know that the gravitational waves______.

A. are not supposed to be observed.

B. are very huge.

C. are easy to be found.

D. can’t be seen with our eyes.

3.Why did scientists spend years watching two black holes?

A. Because they wanted to see how the two black holes crashed into each other.

B. Because they wanted to find the gravitational waves.

C. Because they wanted to see the gravitational waves reach the Earth.

D. Because they wanted to know how black holes formed.

4.What can we infer from the passage?

A. The discovery has no relation to Albert Einstein's theory

B. Throwing a rock into a pond can generate gravitational waves

C. The discovery will considerably affect people’s understanding of universe

D. gravitational waves can’t contract and expand the Earth

阅读下列短文,从每题所给的A、B、C、D 四个选项中,选出最佳选项.

Do you know electricity can change the way we taste food? Proving this fact is a revolutionary electric fork designed by Japanese researchers that can make any dish taste salty.

According to Hiromi Nakamura, a Post Doc Research Fellow at

Tokyo’s Meiji University, the technology can be very useful for people on

special diets. Patients with high blood pressure, for instance, can easily go

on a low-salt diet and still enjoy delicious food. And with the fork, there’s absolutely no risk of over-salting their food. Luckily, the voltage(电压) is so small that there is no risk of electrocution(触电) either.

The idea of adding electricity to food was first exposed as an experiment at the Computer

Human Interaction Conference in Austin, Texas, in 2012. Nakamura and her team connected a wire

to a 9-volt battery and passed it through a straw placed in a cup of sweet lemonade. Volunteers

reported that the charged lemonade tasted ‘blander’, because the electricity created the taste of salt.

Nakamura has improved the technology to be able to transfer an electric charge to food through

forks and chopsticks. “The metallic part of the fork is one electrode(电极), and the handle is the

other,” Nakamura explained. “When you take a piece of food with the fork and put it in your mouth,

you connect the circuit. When you remove the fork from your mouth, you disconnect the circuit. So

it actually works as a switch.”

Simon Klose, host of food program Munchies, who recently visited Nakamura to try out the

fork himself, called this form of ‘food hacking’ one of the greatest eating experiences he’d ever had.

“When I first heard of electric food, it sounded scary,” he said. He later continued to use a charged

fork to eat pieces of fried chicken, and found that the saltiness considerably increased as the electricity was connected.

Nakamura has been eating ‘electric’ food for the past three to four years in an attempt to

understand it better. “For me, ‘food hacking’ is about strengthening or weakening real food,” she

said. “It may seem like we’re cooking but we’re actually working on the human senses.”

1.The electric fork may benefit people who__________.

A. need to go on a diet B. have high blood pressure

C. prefer food free of salt D. show interest in tasty food

2. Paragraph 4 mainly tells us _________.

A. how the electric fork works

B. what makes the circuit connected

C. how the technology was improved

D. why the electric fork was invented

3. From the passage, we learn that the electric fork______.

A. creates virtual taste B. changes people’s diets

C. helps cure diseases D. replaces salt in cooking

根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Empathy

Last year,researchers from the University of Michigan reported that empathy,the ability to understand other people,among college students had dropped sharply over the past 10 years. That could be because so many people have replaced face time with screen time,the researchers said. 1. .

Jennifer Freed,a co?director of a teen program,has another explanation.Turn on the TV,and you're showered with news and reality shows full of people fighting,competing,and generally treating one another with no respect. 2. .

There are good reasons not to follow those bad examples.Humans are socially related by nature. Having relationships with other people is an important part of being human — and having empathy is decisive to those relationships. Researchers have also found that empathetic teenagers are more likely to have high self?respect. 3. .Empathy is also an indication of a good leader.In fact,Freed says,many top companies report that empathy is one of the most important things they look for in new managers. 4. “Academics are important.But if you don't have emotional (情感的) intelligence,you won't be as successful in work or in your love life,” she says.

What's the best way to up your EQ (情商)? For starters,let down your guard and really listen to others. 5. .

To really develop empathy,you'd better volunteer at a nursing home or a hospital,join a club or a team that has a diverse membership,have a “sharing circle” with your family,or spend time caring for pets at an animal shelter.

A. Today,people spend more time alone and are less likely to join groups and clubs.

B. “One doesn't develop empathy by having a lot of opinions and doing a lot of talking,” Freed says.

C. Humans learn by example and most of the examples on it are anything but empathetic.

D. Empathy is a matter of learning how to understand someone else — both what they think and how they feel.

E. Good social skills, including empathy, are a kind of “emotional intelligence” that will help you succeed in many areas of life.

F. Besides,empathy can be a cure for loneliness,sadness,anxiety,and fear.

G. Everyone is different,and levels of empathy differ from person to person.
