【题目】 Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean-energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.

Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between 216 and 368 ($306-521) per MWh of electricity by 2025, compared with 58-75 for seagoing wind turbines (轮机) and 55-76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.

An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).

But there would be nothing old-fashioned about Mr Rainey’s wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.

【题目】 The Great Depression that followed the stock market crash of 1929 saw hundreds of thousands of Americans out of work. In the years of great fear and depression, a lot of American citizens looked desperately to the federal government for assistance. Of all the programs designed by President Roosevelt when he took office in 1932, few were more criticized---or had more lasting impact---than the Work Projects Administration, better known as the WPA.

The intention of the WPA, which functioned from 1935 to 1943, was to design and administer public works projects to help relieve unemployment. The majority of these projects involved historic or artistic attempts. The WPA’s Writers Project, for example, was responsible not only for such practical works as state guidebooks but also for the collection of historically valuable oral histories. Over 2,900 of these records were collected in 24 states. They provide an irreplaceable firsthand account of people’s diets, customs, celebrations, and political and religious beliefs at the time.

The artworks created through the Federal Arts Project are one of the WPA’s most lasting achievements. Out-of-work painters, both famous and unknown, created paintings that beautified schools, libraries, and government buildings, WPA photographers traveled across the country recording the hardships of life on small rural farms. When the United States entered World War in 1941, WPA artists were enlisted to produce posters supporting the war effort. Many WPA artworks, including hundreds of small drawings picturing scenes of everyday life, still exist today.

1When did the Work Projects Administration begin to work?

A.In1929.B.In1932.

C.In1935.D.In 1943.

2What can be inferred about the WPA?

A.It was made up of several components.

B.It was President Roosevelt’s favorite project.

C.It played an important role during World War .

D.It trained artists before sending them out to work.

3How does the author mainly develop this text?

A.By examples.B.By comparison.

C.Through a true story.D.Through a persuasive argument.

4What’s the main idea of the text?

A.President Roosevelt designed the WPA.

B.The WPA helped relieve unemployment.

C.WPA artists painted pictures in schools and libraries.

D.The WPA produced many valuable and lasting works.

【题目】 Politeness is the practical application of good manners, the goal of which is to make all of the parties relaxed and comfortable. It's a flexible management of words and actions, by which we make other people have a better opinion of us and themselves. It seeks to build a positive relationship. 1.

There are simple things we can do to be considered as a polite and well-mannered person.5, they will respect you back. Just make a change in our behavior to start. Use simple words like “Excuse me”, “Please”, and “Thank you” every day. Be kind to receive kindness. Care and politeness will get you far in all aspects of life.

A.As technology progresses

B.People have become more self-absorbed

C.As long as you show your politeness for people

D.Since for many people being polite remains a challenge

E.Many languages have specific means to show politeness

F.It aims to respect a person’s need to be liked and understood

G.It’s also about being kind, caring and respectful to another person

【题目】 Once I had a student called Jamal. He would squirm (扭来扭去)in his chair during independent work, and he would never stay still for more than three or four minutes. Students like Jamal can confuse brand new teachers because they’re not quite sure how to support young people like him. I took a direct approach. I negotiated with Jamal. If he could give me focused work, then he could do it from anywhere in the classroom: from our classroom rug, from behind my desk, or from inside his classroom locker, which turned out to be his favorite place.

Jamal’s least favorite subject was writing, and he never wanted to read what he had written out loud in class, but we were still making progress. One day, I decided to host a mock (模拟的)2008 presidential election in my classroom. My third graders had to research and write a speech for their chosen candidate: Barack Obama, Hillary Clinton or John McCain. The favorite candidates were obvious, but one student chose John McCain. It was Jamal. Jamal finally decided to read something that he had written out loud in class, and sure enough, Jamal stunned all of us with his brilliance. Just like Jamal’s dad, John McCain was a veteran, and just like Jamal’s dad protected him, Jamal believed that John McCain would protect the entire country. He wasn’t my candidate of choice, but it didn’t matter, because the entire class erupted into applause for our brave friend Jamal who finally showed up as his most confident self for the first time that year.

A lack of confidence pulls us down from the bottom and weighs us down from the top, crushing us between a flurry of can’ts and won’ts. Without confidence, we get stuck, and when we get stuck, we can’t even get started. Instead of getting mired in what can get in our way, confidence invites us to perform with certainty.

1Which of the following best describes Jamal?

A.Naughty and stubbornB.Determined but shy

C.Smart but unfocusedD.Confident and generous

2Why did Jamal choose John McCain in the mock 2008 presidential election?

A.Because John was the least popular among the three choices.

B.Because John had written something about him before.

C.Because John shared some similarities with Jamal’s father.

D.Because John was a soldier who could protect the country.

3What does the underlined word “stun” mean?

A.Amaze.B.Cheer.C.Awake.D.Entertain.

4What is the main purpose of the text?

A.To introduce the change of the authors student.

B.To show how to deal with problem students.

C.To stress the importance of encouragement.

D.To encourage us to be confident.
