Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.
For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.
When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.
While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.
What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.
However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!What’s the best title of the passage?

Culture is one of the most challenging elements of the international marketplace. This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by set of dynamic variables: language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions. To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience.
The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.
The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness.
Fortune examined the international performance of a dozen large companies that earn 20 percent or more of their revenue(税收) overseas. The internationally successful companies all share an important quality: patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer.According to the passage, which of the following is true?
| A．All international managers can learn culture. |
| B．Business diversity is not necessary. |
| C．Views differ on how to treat culture in business world. |
| D．Most people do not know foreign culture well. |
What does the underlined word “myopia” (in para. 3) mean?

One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.
While computer offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers. From the last sentence of the first paragraph we learn that ___________.
| A．in the future all the Americans will use credit cads |
| B．credit cards are mainly used in the United States today |
| C．nowadays many Americans do not pay in cash |
| D．it is now more convenient to use credit cards than before |
If computers record which hours are busiest and which employees are the most efficient, what will businessmen do?
| A．They will fire some employees and raise the work efficiency. |
| B．They will arrange for different employees to do different jobs according to their abilities and performance. |
| C．They will assign more work for the employees to do. |

Researchers recently found that hackers took control of 300,000 home routers(路由器). Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router.
Say no to 12345 passwords
First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.
Don't broadcast it
Make sure you don't show up in other people's wireless network scans. Know your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings.
Invite only please
One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses.
Turn it off
This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running?
Build a firewall
The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network – and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far.
For further protection, you should run software firewalls on the individual PCs on your networks. If you use the default password, ______________.
| A．your home router will be linked to some bad websites. |
| B．you will find it’s very convenient to surf the Internet |
| C．your home router will be changed for new settings. |
| D．you will fail to use your own login password |
What should be done to shelter your wireless network?
| A．To build a firewall into your router. |
| B．To think out a complicated login password and use it. |
| C．To shut off your router when you find it not safe. |
| D．To switch off broadcasting in your router settings |
The purpose of the passage is to tell____________.
| A．how to keep your Wi-Fi network secure |
| B．how to deal with your home router efficiently |
| C．how to locate the hackers on the Internet |
| D．how to prevent others from joining your network. |
I never knew how amazing it would feel to help a family 4,560 miles away from my home. I never knew how great an effect I could have on that single family.
From the moment I walked into French class, I knew almost instantly that I belonged there. My teacher, Madame Weiser, is a kind and caring woman, and is the person who started the interest within me to help a family abroad, no matter how many miles apart.
Back in 2011, my teacher traveled as a tourist to Maxi, a country settled in West Africa with a large French-speaking population. She didn’t expect to adopt an entire family, but fate had other plans. Madame met a nice man named Monsieur Diarra, a driver who had shown her the way through the dry lands of Mali.
Mali is now a war-torn country and unsafe for tourists to visit, leaving little work for taxi drivers. Madame Weiser realized how Monsieur Driarra’s family struggled on a daily basis, for he had a wife and four children to support as well as their grandmother, so she made a final decision to send the family as much money as she could raise every month.
Now, three years later, Madame Weiser has still kept up her fund, collecting money from family and friends as well as students to support the cause. It has become more than just my teacher donating to her adopted family abroad.
As president of French Club at my high school and a French Honor Society member, I decided that our club should work to raise money for the family in need. By washing cars, we raised over $1,000.
From my experience, I’ve learned that making an effort is worth more than anything. Its effect is priceless! Why do taxi drivers have difficulty finding work in Mali?
| A．People don’t like taking a taxi. |
| B．Tourists visiting Mali are few. |
| C．Mali is very unsafe for them. |
| D．Public transport is enough. |
What does the underlined expression “the cause” refer to?
| A．Teaching Trench in West Africa. |
| B．Looking for jobs for the drivers in Mali. |
| C．Helping the homeless as much as possible. |
| D．Donating money to the adopted family abroad. |
What did the writer think of her experience?
| A．Boring | B．Puzzling |
| C．Satisfying. | D．Relaxing. |
What is the best title of this passage?
| A．The Love for Africa. | B． A Kind Foreign Driver. |
| C．My Helpful Teacher | D．My Unforgettable Class |
People are being tricked into Facebook with the promise of a fun, free service without realizing they’re paying for it by giving up loads of personal information.
Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook because people don’t really know what their personal data is worth.
The biggest problem, however, is that the company keeps changing the rules . That was the great thing about Facebook. You could create your own little private network. Last year, the company changed its privacy rules so that many things: your city, your photo, your friends’ names ,were set by default (默认)to be shared with everyone on the Internet.
According to Facebook’s vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience”.
Some critics think this is more about Facebook looking to make more money. In original business model, which involved selling ads and putting them. At the side of the pages totally, who wants to look at ads when they’re online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington. In April, Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy, it’s only the beginning, which is why I’m considering canceling my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That’s too high a price to pay. What do we learn about Facebook from the first paragraph?
| A．It provides loads of information to its users. |
| B．It earns money by putting on advertisements. |
| C．It is a website that sends messages to users who want to get married. |
| D．It makes money by selling its users’ personal data. |
What does the author say about most Facebook users?
| A．They don’t know their personal data enriches Facebook. |
| B．They are unwilling to give up their personal information. |
| C．They don’t identify themselves when using the website. |
| D．They care very little about their personal information. |
Why does Facebook make changes to its rules according to Elliot Schrage?
| A．To obey the Federal guidelines. |
| B．To expand its business. |
| C．To improve its users’ connection |
| D．To provide better service to its users |
Why does the author plan to cancel his Facebook account?
| A．He is dissatisfied with its present service. |
| B．He finds many of its users untrustworthy. |
| C．He doesn’t want his personal data badly used. |
| D．He is upset by its frequent rule changes. |
