Durian(榴莲) is probably the smelliest fruit in the world, letting out an unusual unpleasant smell which would make anyone bring up. However, nobody was aware of what gave this fruit its unique smell, so a team of researchers from Singapore decided to take a look at its genome (基因组) and find out,
Durian is well-known throughout Southeast Asia as the king of fruits, mostly because of its awful appearance and smell. However, the origin of this unpleasant smell was unknown, so researchers decided to map the genome of the fruit, and find the gene that controlled it. A group of genes, volatile sulfur compounds (含硫化合物), became very active in the fruit, and they were found responsible for resulting in the unpleasant smell.
The fruit confuses everyone with a sulfuric smell, like rotten onions and ingredients. The smell lasts long, mostly because the fruit contains more volatile sulfur compounds. Other species usually benefit from two gene copies at most, but durian has four, leading to the striking smell.
However, this smell might be an advantage for durian in the wild. Although we find it unpleasant, many animals might be attracted by it. If they eat the fruit, then they can easily spread its seeds everywhere, thus contributing to the distribution of the species.
The mapping of the durian genome also showed some other information on the species. First of all, the fruit has an impressive number of genes, namely 46,000. Also, with the help of these genes, they saw how it evolved, and discovered it was related to the cacao tree. All the other discoveries have been published in the journal Nature Genetics.
Despite the striking smell, many people actually enjoy eating the fruit. However, not all durian species are edible, and some of them may even cause damage to our health, Even so, the fruit is often imported, significantly contributing to the economy.

There are a great number of people in the world while few people are great.I think there is probably only one great person out of 10,000 at best,and most probably much less than that.
The reason why there are only few of them is that most people do not pay the price of greatness.There are so many people who want to be great,why only very few of them actually pay the price? The answer to the question explains the difference between the almost 100% people who want to be great and the much less than 0.01% who actually be so.The reason is that the road to greatness is full of pains.
Greatness requires sacrifices and there is no sacrifice without pain.The kind of sacrifices required for greatness is the ones that make the process continuously painful for long time.If you only want to be good it may be painful just every now and then,and many people can still handle it.But being great is a total difference.The pain is much deeper and it is continuous,so very few people can endure this kind of pain.Most people naturally choose things that bring pleasures to them.It's unnatural to choose pain over pleasure,let alone doing it continuously for long time.But that's what I believe is the secret to greatness: The secret to greatness is choosing pain over pleasures continuously for long time.
1.What is the purpose of Paragraph 1?
A.To compare. B.To list statistics.
C.To lead up to the topic. D.To give information.
2.If one person only wants to be good,what will he/she face?
A.Occasional pains. B.Continual work.
C.Constant pains. D.Various difficulties.

A.Pleasures mean greatness.
B.Greatness equals sacrifices.

Let's face it: The last hour of anyone's workday is not always fruitful. As the hours of peak productivity start to decline, most people begin watching the clock, waiting for nothing.1.“How positively you end your professional day can promote success both inside and outside of the office,” says Randi Levin, a transitional life strategist. Let's see how successful people end their workday with a bang.
Successful people reflect on their accomplishments. While many of us spend our last hour of work making a to-do list for tomorrow, they review the day they just had, instead.2.Similarly, Levin recommends writing down the day's wins rather than setbacks or to-dos, as well as reviewing your list of successes once a month. It will prove your professional growth and bring more joy into your job.
Also, successful people brainstorm solutions for today's setbacks.3.Instead, they end their day by thinking carefully about the problems they met, brainstorming possible solutions, and then leaving it for tomorrow. They will settle those problems after a good night's sleep.
4.Rather than detailing the tasks that need to get done, this kind of list encourages people to focus on finding solutions for their projects. “Forget the horrible 'to-do' list,” Levin says, “before heading to happy hour, write down three to five goals you have for the next 24 hours.5.It will provide you with not only a concrete and positive way to begin tomorrow, but also it will allow you to see much more possibilities.”
A.This list is a promise to yourself.
B.Successful people make a to-do list.
C.It will make people understand the problems better.
D.They never bring the day's failures home with them.
E.Another work these people do is to create an action list.
F.But ending the workday with purpose can make a difference.
G.They typically choose a case and consider what led to that success.

When it comes to cultural heritage protection, the Grand Canal of China is probably the world’s greatest project of its kind. The big inland waterway system in the north-eastern and central eastern plains passes through eight of the country’s present-day provinces.
The Canal runs from Beijing in the north to Zhejiang Province in the south. Constructed in sections from the 5th century BC onwards, it was designed as a means of communication in the 7th century AD. The Canal is the world’s greatest civil engineering project before the Industrial Revolution.
The Grand Canal reached a peak in the 13th century, providing an inland navigation(航行) network consisting of more than 2,000 kilometers of artificial waterways, linking five of the most important river basins in China, including the Yellow River and the Yangtze. It entered a bid as a UNESCO(联合国教科文组织) cultural heritage site in 2008.
The Grand Canal cultural square is located in Beijing’s Tongzhou district. Ever since the Yuan dynasty 800 years ago, the Tongzhou section of the Grand Canal has been the life blood of Beijing. Grain and building materials were all transported to meet the endless demands of the big cities. Even today, the Grand Canal plays a major role in the lives of its citizens.
"I grew up near the Grand Canal. In the past the waterway was a lot narrower, but now it’s nice and wide and bridges are built over it. I think if the bid for world heritage status succeeds, it will greatly make Tongzhou more famous in the world, especially with Tongzhou aiming to be a sub-center of the capital Beijing," a citizen said.
The result of the bid is set to be released next week, and no doubt it will certainly make it into the history books if the Canal is listed as a world heritage site.
1.It can be concluded from the passage that ________ .
A. The bid’s result of the Canal will be announced soon
B. the Canal is the UNESCO’s newest world heritage site
C. the Canal is to connect Tongzhou with Zhejiang Province
D. the Canal will be a bid for a UNESCO cultural heritage site
2.The Grand Canal was in the most glorious time ________ .
A. when it was aimed as a means of communication
B. when it crossed the Yellow River and the Yangtze
C. when it was born about six hundred years later
D. when it was designed as an artificial waterway
3.What can we infer by reading the passage?
A. Tongzhou used to be the capital of the Yuan dynasty.
B. Most citizens living in Tongzhou depend on the Canal.
C. Tongzhou will benefit if the Canal is made a heritage site.
D. Some citizens think the Canal not to be a cultural heritage item.

Peter Drucker is the world’s most influential management master. Probably more than anyone else, he has helped to determine the nature of management and the tasks and responsibilities of the manager.
Drucker’s interests have ranged broadly. In the 1930s and the 1940s, he wrote a series of thoughtful books on capitalist society. From the 1950s to the 1970s, he wrote a series of books on management. Since the late 1970s, he has been more interested in the impact of technological and social change on management and business.
Drucker’s writings avoid formal theories of management and organization and instead encourage managers to ask basic questions. Famously, he urged managers to stop trying to manage processes and instead seek to manage for results, emphasizing output rather than function. In his view, managers should be the pivot around which the organization works, rather than directors controlling from the top down or officers leading from the front.
According to Drucker, it is the manager who breathes life into the enterprise and makes it function. “The enterprise can decide, act and behave only as its managers do.”
In a milestone passage, Drucker says that there is only one valid purpose for a business:“To create a customer. Markets are not created by nature or economic forces, but by the people who manage a business.” Drucker emphasizes the need to consider the needs and motivations of customers, not just the problems of price and distribution that had formerly controlled marketing.
He also stresses the responsibilities of managers: to achieve economic performance, to make work productive and to manage the social effects that any enterprise has on its environment. Particularly important is the third set of responsibilities. Increased social responsibility, says Drucker, is part of the price that must be paid for commercial success.
Drucker sees management as an art rather than a science and constantly speaks of management in human terms, which has made him the most popular and widely read management writer of all time.
1.What is the text mainly about?
A.The biography of Peter Drucker.
B.What makes a good business.
C.The responsibilities of managers.
D.Peter Drucker and his influence on management.
2.What does the underlined word “pivot” in paragraph 3 mean?
A.Helper. B.Center.
C.Adviser. D.Controller.
3.Which of the following is true according to the text?
A.Controlling the process of the business is the key to success.
B.Price and distribution decide the domination of markets.
C.A business works well if it has a good functional manager.
D.Managers should put the domination of markets above all.
4.The responsibilities of a manager doesn’t include __________.
A.improving the profit
B.better working efficiency
C.ensuring a better society
D.paying the price for his or her faults

Probably no other musical instrument is as popular as the guitar around the world. Musicians use the guitar for almost all kinds of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.
