Many of us love July because it's the month when nature's berries and stone fruits are in abundance．These colourful and sweet jewels from British Columbia's fields are little powerhouses of nutritional protection．
Of the common berries， strawberries are highest in vitamin C， although， because of their seeds， raspberries contain a little more protein （蛋白质）， iron and zinc （not that fruits have much protein）． Blueberries are particularly high in antioxidants （抗氧化物质）． The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants． As for cherries （樱桃）， they are so delicious who cares？ However，they are rich in vitamin C．
When combined with berries of slices of other fruits， frozen bananas make an excellent base for thick， cooling fruit shakes and low fat "ice cream"． For this purpose， select ripe bananas for freezing as they are much sweeter． Remove the skin and place them in plastic bags or containers and freeze． If you like， a squeeze of fresh lemon juice on the bananas will prevent them turning brown． Frozen bananas will last several weeks， depending on their ripeness and the temperature of the freezer．
If you have a juicer ，you can simply feed in frozen bananas and some berries or sliced fruit．Out comes a "soft﹣serve" creamy dessert，to be eaten right away． This makes a fun activity for a children's party；they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below．

Suppose you become a leader in an organization. It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.
Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.
People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people’s wish of participation from an internal factor (e.g., “I volunteer because it’s important to me”) to an external factor (e.g., “I volunteer because I’m required to do so”). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.
Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.
Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in Hospital is an important part of who I am.” Consistent with the researchers’ expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: “Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity.... Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity”.People volunteer mainly out of ______ .
| A．academic requirements | B．social expectations |
| C．financial rewards | D．internal needs |
What can we learn from the Florida study?
| A．Follow-up studies should last for one year. |
| B．Volunteers should get mentally prepared. |
| C．Strategy training is a must in research. |
| D．Volunteers are provided with concrete advice. |
What is most likely to motivate volunteers to continue their work?
| A．Individual differences in role identity. |
| B．Publicly identifiable volunteer T-shirts. |
| C．Role identity as a volunteer. |
| D．Practical advice from researchers. |

In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.
Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.
Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.
Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.
The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying reusable products and recycling.
In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?
Governments’ incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?
From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.
By mentioning the Swiss study, the author intends to tell us that _________ .
| A．the weight of e-goods is rather small |
| B．E-waste deserves to be made good use of |
| C．natural minerals contain more precious metals |
| D．the percentage of precious metals is heavy in e-waste |
The responsibility of e-waste treatment should be extended _________ .
| A．from producers to governments |
| B．from governments to producers |
| C．from individuals to distributors |
| D．from distributors to governments |
What does the passage mainly talk about?
| A．The increase in e-waste. |
| B．The creation of e-waste. |
| C．The seriousness of e-waste. |
| D．The management of e-waste. |

Life in the Clear
Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”
And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.
The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.
But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.
To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.
Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .
Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.According to Paragraph 1, transparent animals_______.
| A．stay in groups | B．can be easily damaged |
| C．appear only in deep ocean | D．are beautiful creatures |
The underlined word “dead” in Paragraph 3 means__________.
| A．silently | B．gradually |
| C．regularly | D．completely |
One way for an animal to become transparent is to ________.
| A．change the direction of light travel |
| B．gather materials to scatter light. |
| C．avoid the absorption of light |
| D．grow bigger to stop light. |
The last paragraph tells us that larger transparent animals________.
| A．move more slowly in deep water |
| B．stay see-through even after death |
| C．produce more tissues for their survival |
| D．take effective action to reduce light spreading |
D
The oddness of life in space never quite goes away. Here are some examples.
First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. "I'm an inside guy," Mike Hopkins says, who returned from a six-month tour on the International Space Station. "I like to be wrapped up."
On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.
Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,"Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying-that's why some people feel sick." Within a couple days -truly terrible days for some -astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.
Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.

One of the executives gathered at the Aspen Institute for a day-long leadership workshop using the works of Shakespeare was discussing the role of Brutus in the death of Julius Caesar. “Brutus was not an honorable man,” he said. “He was a traitor（叛徒）. And he murdered someone in cold blood.” The agreement was that Brutus had acted with cruelty when other options were available to him. He made a bad decision, they said—at least as it was presented by Shakespeare—to take the lead in murdering Julius Caesar. And though one of the executives acknowledged that Brutus had the good of the republic in mind, Caesar was nevertheless his superior. “You have to endeavor,” the executives said, “our policy is to obey the chain of command.”
During the last few years, business executives and book writers looking for a new way to advise corporate America have been exploiting Shakespeare’s wisdom for profitable ends. None more so than husband and wife team Kenneth and Carol Adelman, well-known advisers to the White House, who started up a training company called “Movers and Shakespeares”. They are amateur Shakespeare scholars and Shakespeare lovers, and they have combined their passion and their high level contacts into a management training business. They conduct between 30 and 40 workshops annually, focusing on half a dozen different plays, mostly for corporations, but also for government agencies.
The workshops all take the same form, focusing on a single play as a kind of case study, and using individual scenes as specific lessons. In Julius Caesar , sly provocation（狡诈的挑唆） of Brutus to take up arms against the what was a basis for a discussion of methods of team building and grass roots organism.
Although neither of the Adelmans is academically trained in literature, the programmes, contain plenty of Shakespeare tradition and background. Their workshop on Henry V, for example, includes a helpful explanation of Henry’s winning strategy at the Battle of Agincourt. But they do come to the text with a few biases (偏向): their reading of Henry V minimizes his misuse of power. Instead, they emphasize the story of the youth who seizes opportunity and becomes a masterful leader. And at the workshop on Caesar, Mr. Adelmans had little good to say about Brutus, saying “the noblest Roman of them all” couldn’t make his mind up about things.
Many of the participants pointed to very specific elements in the play that they felt related Caesar’s pride, which led to his murder, and Brutus’s mistakes in leading the after the murder, they said, raise vital questions for anyone serving as a business when and how do you resist the boss?
According to paragraph 1, what did all the executives think of Brutus?
| A．Cruel. | B．Superior. |
| C．Honorable. | D．Bade. |
According to the passage, the Adelmans set up “Movers and Shakespeares” to ________.
| A．help executives to understand Shakespeare’s plays better |
| B．give advice on leadership by analyzing Shakespeare’s plays |
| C．provide case studies of Shakespeare’s plays in literature workshops |
| D．guide government agencies to follow the characters in Shakespeare’s plays. |
Why do the Adelmans conduct a workshop on Henry V?
| A．To highlight the importance of catching opportunities. |
| B．To encourage masterful leaders to plan strategies to win. |
| C．To illustrate the harm of prejudices in management. |
| D．To warn executives against power misuse. |
It can be inferred from the passage that ____.
| A．the Adelmans’ programme proves biased as the roles of characters are maximized. |
| B．executives feel bored with too many specific elements of Shakespeare’s plays. |
| C．the Adelmans will make more profits if they are professional scholars. |
| D．Shakespeare has played an important role in the management field. |
The best title for the passage is _____.
| A．Shakespeare’s plays: Executives reconsider corporate culture |
| B．Shakespeare’s plays: An essential key to business success |
| C．Shakespeare’s plays: a lesson for business motivation |
| D．Shakespeare’s plays: Dramatic training brings dramatic results |
