Because they’re literally rooted into the ground, they are unable to leave and go (26)_____. When a tree first starts growing in a certain area, it’s likely that the (27)_____ envelope—the temperature, humidity, rainfall patterns and so on—suits it. Otherwise, it would be unable to grow from a seedling. But as it (28)_____, these conditions may change and the area around it may no longer be suitable for its (29)_____. When that happens, many trees like walnuts, oaks and pines, rely (30)_____ on so-called “scatter hoarders”, such as birds, to move their seeds to new localities. Many birds like to store food for the winter, which they (31)_____ retrieve. When the birds forget to retrieve their food—and they do sometimes—a seedling has a chance to grow. The bird Clark’s nutcracker, for example, hides up to 100,000 seeds per year, up to 30 kilometers away from the seed source, and has a very close symbiotic (共生的) relationship with several pine species, most (32)_____ the white bark pine. As trees outgrow their ideal (33)_____ in the face of climate change, these flying ecosystem engineers could be a big help in (34)_____ trees. It’s a solution for us—getting birds to do the work is cheap and effective—and it could give (35)_____ oaks and pines the option to truly “make like a tree and leave”.

What makes a group intelligent You might think a group’s IQ would be simply the average intelligence of the group’s members, or perhaps the intelligence of the team’s smartest participant. But researchers who study groups have found that this isn’t so. Rather, a group’s intelligence emerges from the interactions that go on within the group. A team’s intelligence can be measured, and like an individual’s IQ score, it can accurately predict the team’s performance on a wide variety of tasks. And just as an individual’s intelligence is expandable, a group’s intelligence can also be increased. Here are five suggestions on how to guide the development of smart teams: Choose team members carefully. The smartest groups are composed of people who are good at reading one another’s social cues, according to a study led by Carnegie Mellon University professor Anita Williams Woolley and published in the journal Science. Talk about the "how". Many members of teams don’t like to spend time talking about "process", preferring to get right down to work―but Woolley notes that groups who take the time to discuss how they will work together are ultimately more efficient and effective. Share the floor. In the most intelligent teams, found Woolley, members take turns speaking. Participants who dominate the discussion or who hang back and don’t say much bring down the intelligence of the group. Alex Sandy Pentland, an MIT professor who studies group dynamics, has found that in smart teams, members connect directly with one another―not just with the team leader―and they’re constantly engaging in "back channel" or side conversations that supplement the main discussion. Boost informal social connections among members. The smartest teams spend a lot of time communicating outside of formal meetings, says Pentland. He tells of a call center where team members’ coffee breaks were staggered across the workday. Changing the schedule so that all members had a coffee break at the same time led them to do their work more efficiently and feel more satisfied with their jobs. Be open to external influences. In the most successful groups, Pentland discovered, team members regularly take off on their own to explore and discover. They then bring that information back to the group, stimulate the group’s work with fresh insights from the world outside the conference room.By saying "Be open to external influences" (Line 1, Para. 7), the author suggests ______. A．team members are willing to explore and discover on their ownB．team leaders can improve their teams’ work with some fresh ideasC．smart teams absorb new insights from the world outside the meeting roomD．smart teams often hold a brainstorming session outside the conference room

Does money buy happiness Not! Ah, but would a little more money make us a little happier Many of us smirk (傻笑，假笑) and nod. There is, we believe, some connection between fiscal fitness and emotional fulfillment. Three in four American collegians (大学生) now consider it "very important" or "essential" that they become "very well off financially." Money matters. But a surprising fact of life is that in countries where nearly everyone can accord life’s necessities, increasing affluence matters surprisingly little. The correlation between income and happiness is "surprisingly weak," observed University of Michigan researcher Ronald Inglehart in one 1B-nation study of 170,000 people. Once comfortable, more money provides diminishing returns. The second piece of pie, or the second100,000, never tastes as good as the first. Even lottery winners and the Forbes’ 100 wealthiest Americans have expressed only slightly greater happiness than the average American. Making it big brings temporary joy. But in the long run wealth is like health: its utter absence can breed misery, but having it doesn’t guarantee happiness. Happiness seems less a matter of getting what we want than of wanting what we have. Has our happiness floated upward with the rising economic tide Are we happier today than in 1940s, when two out of five homes lacked a shower or tub Actually, we are not. Since 1957, the number of Americans who say they are "very happy" has declined from 35 to 32 percent. Meanwhile, the divorce rate has doubled, the teen suicide rate has nearly tripled (使成三倍), the violent crime rate has nearly quadrupled (使成四倍)(even after the recent decline), and more people than ever (especially teens and young adults) are depressed. This soaring wealth and shrinking spirit is called" the American paradox". More than ever, we have big houses and broken homes, high incomes and low morale, secured rights and diminished civility. We excel at making a living but often fail at making a life. We celebrate our prosperity but yearn for a purpose. We cherish our freedoms but long for connection. In an age of plenty, we feel spiritual hunger."The second ＄100,000 never tastes as good as the first", because（） A. it’s not so fresh as the first ＄100,000 B. it is not so important as the first ＄100,000 C. profit brought by it is less than that from the first ＄100,000 D. happiness brought by it is less than that from the first ＄100,000
