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,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

We all use money every day. It is essential because we can pay money for whatever we want.Money is recognized as banknotes and coins.

However,many years ago people couldn’ t go to the shop and buy what they wanted.They had to get what they wanted through the barter trade(实物交易).It was really difficult,for the barter often depended on coincidence of wants.For example,the seller of grain has to find a buyer who wants to buy grain and who also could offer something the seller wants to buy.And one more example,if a wheat farmer needs what a fruit farmer produces,a direct exchange is impossible because seasonal fruit would spoil before the grain harvest.The solution is to trade fruit for wheat indirectly through a third intermediate commodity(中间的商品),such as cattle,salt,shells,wine.However,commodity money had their disadvantages.For example,cattle,fur,precious stones couldn’ t be cut into smaller pieces and it was inconvenient to keep and transport them.Thus coins were invented.

The earliest known coins in the western world came from Lydia in about 650 B.C.Greek cities,the Great Persian Empire and Roman Empire quickly adopted the new useful technique of metal currency.And by the end of the 6th century,coinages were common throughout the region.However,coins as well as commodity money had many disadvantages.For instance,coins quickly show wear(磨损) and they usually have small value,so it’ s difficult to count large sums of coins.

At first,paper money was used in China in about 650 A.D.After then,it was used in Persia and Japan.In Europe,paper money was firstly produced in the Netherlands in the 16th century and in the USA in the 17th century.Paper money is worthless but symbolic.In other words,paper money is just a note.It has a purchasing power because the government announces it as money and citizens accept it universally.

1.The writer explains the difficulty of barter trade by_______.

A. telling stories B. using examples

C. presenting a theory D. making a comparison

2.What do we know about the early coins?

A. They usually had large value.

B. They were first used in Greece.

C. They still had many disadvantages.

D. People didn’ t like the metal currency.

3.Paper money was used earlier in_______.

A. Rome B. Greece

C. the USA D. the Netherlands

4.What is the passage mainly about?

A. Function of money. B. History of money.

C. Invention of money. D. Types of money.

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.

The Regional Director of the National Heritage Conservation Commission (国家遗产保护委员会) Kagosi Mwamulowe said the Barotse Plains is unique and it deserves to be on the list of the World Heritage Sites.

Mr. Mwamulowe said the Barotse Plains deserves to be included on the World Heritage List because it has a rich cultural heritage which includes the burial sites of former kings.

The Director said he hoped that the landscape would be declared as a heritage site next year in June. He also said it was important to protect Zambia’s unique culture for education and entertainment.

Chief Natural Heritage Officer Muyumbwa Ndiyoi said there will be a lot of benefits when the Barotse Landscape is declared a World Heritage Site because it will attract many tourists and business investments (投资) will increase.

Mr. Ndiyoi said the site will also benefit young people as knowledge will be passed down from generation to generation.

He was reacting to a question from Nalolo District Labour Officer Jason Ngoma who wanted to know how the people of Western Province will benefit once the Barotse Landscape is declared a World Heritage Site.

And University of Zambia Lecturer Charles Namate said there is a need for the site to be included on the World Heritage List because 50 years after its independence Zambia only has one heritage site, which is the Victoria Falls.

Lecturer Namate said the Barotse Landscape was facing a lot of environmental degradation (恶化), and that’s why there is a need to recognize the value of its landscape and the memories of dead kings.

The National Heritage Conservation Commission together with the Ministry of Chiefs and Traditional Affairs are in Western Province to hold meetings with Heads of Government Departments. The Commission also held closed-door meetings with the Litunga Lubosi Imwiko II of the Barotse Royal Establishment.
