Can you imagine a world without chocolate? It's not something I'd 1ike to do．so I was relieved to read that there’s a university with a program me to safeguard the future of chocolate!

The University of Reading，in England，has just opened a new clearing house for all the world’s new cocoa varieties．They must be quarantined(隔离检疫)before they can be grown．Why? Cocoa production hit a record high of 4．4 million tons last year but about 30％of the precious crop is regularly lost to pests and diseases．Now we don’t want that，do we?

Demand for chocolate has been increasing faster than the world supply of cocoa and researchers think that new varieties are key to solving this problem．

The University of Reading has been protecting the quality of the new crops since 1985，after it took over the task from the Royal Botanical Gardens in Kew，London．And it has improved its facilities．The leader of the institution’s cocoa project，Professor Paul Hadley，says，“One of the main issues concerning cocoa improvement is the supply of reliably clean，healthy，interesting cocoa material．”

The cocoa centre has a collection of 400 plant varieties and their greenhouse uses a lot of　 energy to keep them in tropical conditions．After up to two years in quarantine，clean and safe　 seeds are sent to some 20 countries，including several in West Africa．That’s where 75％of the　 cocoa used for chocolate worldwide comes from．The crop is extremely important for the local　 economy：it employs about two million people.

Professor Hadley says he works with a small team of skilled technicians who look after the collection．And more of us seem to count on them now．

The scientist says，“there is some concern within the industry that demand is increasing　 constantly，particularly in countries like China，where the standard of living is increasing and　 people are getting a taste for different chocolates．”

1.What is the text mainly about?

A. Safeguarding cocoa seeds．

B. Planting cocoa worldwide．

C. Keeping cocoa in greenhouse．

D. Finding the new market for cocoa．

2.The institution’s cocoa project is to_______．

A. have cocoa skin removed

B. offer more jobs to people

D. supply cocoa for two million people

A. The taste of chocolates is changing．

B. Demand for cocoa is increasing fast．

C. People are concerned about cocoa varieties．

D. Chinese have a long history of eating chocolates．

4.What’s the purpose of the text?

You may not be aware, but digital currency (货币) is a big part of the Internet world. QQ Coins can buy you accessories (配饰) for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world’s commerce online.

If you’re traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a café named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins.

So what makes Bitcoin so attractive to investors?

First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation(通货膨胀), as all forms of paper money have done over time.

In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune(有免疫力的) from loss, but that is not entirely true.

“The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation(赔偿),” Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible funds, which also adds to their risk.

While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin.

Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that “these types of creations, such as Bitcoin… may hold long-term promise, particularly if its system promote a faster, more secure and more efficient payment system.”

1.Bitcoin is ______.

A. actually exactly like QQ Coins

B. only used online

C. a new currency used both online and in real life

D a country’s new digital currency.

2.We can use Bitcoin to buy the following things except ______.

A. online goods

B. goods at 134 online shops on Taobao

C. books in physical shops

D. coffee at a café named 2nd Place

3.What is the disadvantage of Bitcoin?

A. the value of it can rise and fall wildly.

B. It cannot lose value through inflation.

C. Every bitcoin in your account can be followed.

D. It can even be used at some specific restaurants and hotels.

Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky with no land in sight and you are sailing straight ahead to meet the world. Jesse Martin does not have to imagine: he is living in it.

On Dec. 7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to become the youngest person to sail alone and nonstop around the world. He sailed south of New Zealand, through the South Pacific, around South America, north on the Atlantic, back south past Africa, through the Indian Ocean and back to Melbourne. Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his parents. Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two years old. They moved close to a rainforest in Cow Bay, about 3,500kms north of Melbourne, where they built a small house with no electricity or running water. Jesse grew up at the beach enjoying the outdoors to its fullest. At 14, he sailed for the first time with his father and brother, Beau. It was after this trip that he began to dream about sailing around the world.

Jesse’s family played an important role. “I was made to believe I could do anything, although there were others that were not so encouraging or supportive” he says. “People that I looked up to, respected and trusted told me I couldn’t. Thankfully, I trusted myself. There were people that said that the boat couldn’t be ready by the time I had to leave.” However, through perseverance(坚持不懈) and belief in himself, he was able to do what many told him was impossible.

On Oct.31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the youngest person to sail around the world alone, nonstop and unassisted.

1.By encouraging readers to imagine a sailing experience, the author wants to __________.

A. show how difficult it is to be a sailor　　 B. describe what Jesse’s sailing is like

2.What can you know from paragraph 2?

A. Jesse was the first person who had sailed alone around the world.

B. Jesse traveled all over Europe and Asia with his parents when he was 17.

C. Jesse was born in Melbourne and grew up at the beach.

D. Jesse grew up in a small house with no electricity or running water.

3.What made Jesse decide to sail alone around the world according to the passage?

A. His childhood adventure experiences.　　 B. His journeys to Europe.

C. His love for outdoor activities.　　 D. His first sailing trip with his family.

4.What can we learn from Jesse Martin’s story?

A. Life is an unusual adventure we should enjoy.　　 B. Failure is the mother of success.

C. A strong belief will make a person stronger.　　 D. Great interest contributes to success.
