Jewelweeds are pretty flowers that grow in wet, shady spots all over the Northern Hemisphere. According to a recent experiment, they seem to know their own flower family —or at least, recognize whether or not they came from the same mother plant. Together with other through their leaves, but through their roots.
Scientists planted jewelweeds in pots with either siblings（兄弟姐妹）or strangers. Sibling plants were grown from seeds that came from the same mother plant. Stranger plants were grown from seeds from different plants.
When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food.
When jewelweed seedlings were planted with siblings, they few a few more branches than they normally would if they were alone—but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete.
The plants only responded this way when they shared soil. If stranger seedlings were planted in different pots and placed next to each other, for example, they did not grow more leaves. This different shows that the plants must use their roots to detect sibling plants in the same soil. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach—where it may be hard to get fresh water. In that experiment, the botanists observed that when sea rockets were planed with siblings, they tolerated each other. But when they were planted with strangers, the sea prickets reacted by working extra hard to grow lots of roots, but not extra leaves.
The different types of plants may react in different ways, but they have one thing in common: the roots. In both experiments, on Jewelweeds and sea rockets, the key was the shared soil—and other plant species may turn out to show similar behavior. These experiments, as well as earlier experiments, suggest “The phenomenon is quite common.” Says Hans de Kroonof, an ecologist in the Netherlands.

A year ago August, Dave Fuss lost his job driving a truck for a small company in west Michigan. His wife, Gerrie, was still working in the local school cafeteria, but work for Dave was scarce, and the price of everything was rising. The Fusses were at

risk of joining the millions of Americans who have lost their homes in recent years. Then Dave and Gerrie received a timely gift－$7,000,a legacy(遗产) from their neighbors Ish and Arlene Hatch, who died in an accident. “It really made a difference when we were going under financially(经济上),” says Dave.
But the Fusses weren’t the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches. Dozens of other families were touched by the Hatches’ generosity. In some cases, it was a few thousand dollars; in others, it was more than $100,000.
It surprised nearly everyone that the Hatches had so much money, more than $3 million—they were an elderly couple who lived in an old house on what was left of the family farm.
Children of the Great Depression, Ish and Arlene were known for their habit of saving. They thrived on(喜欢) comparison shopping and would routinely go from store to store, checking prices before buying something.
Through the years, the Hatches paid for local children to attend summer camp when their parents couldn’t afford it. “Ish and Arlene never asked if you needed anything.” says their friend Sandy Van Weelden. “They could see things they could do to make you happier and they would do them.”
Even more extraordinary was that the Hatches had their farmland distributed(分送). It was the Hatches’ wish that their legacy—a legacy of kindness as much as one of

dollars and cents —should enrich the whole community (社区) and last for generations to come.
Neighbors helping neighbors—that was Ish and Arlene Hatch’s story.
64. According to the text, the Fusses ____________.
A. were employed by a truck company              B. worked in a school cafeteria
C. were in financial difficulty                            D. lost their home
65. Which of the following is true of the Hatches?
A. They gave away their possessions to their neighbors.
B. They left the family farm to live in an old house.
C. They had their children during the Great Depression.
D. They helped their neighbors to find jobs.
66. Why would the Hatches routinely go from store to store?
A. They decided to open a store.                   B. They wanted to save money.
C. They couldn’t afford expensive things       .      D. They wanted to buy gifts for local kids.
67. According to Sandy Van Weelden, the Hatches were _________.
A. mean                  B. childlike                   C. curious

D. understanding

Should we try to contact and make friends with other beings in the universe? Certainly not，says British physicist Stephen Hawking．
“If aliens（creatures from other planets）ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25．
The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets．
“Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach，”warned Hawking．
On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”
Hawking’s concerns have frightened some people and been met with disagreement from other researchers．Paul Davies, author of the book Renewing Our Search for Alien Intelligence，thinks Hawking’s reasoning is wrong.
He argues that since Earth is about 4.5 billion years old，if intel1igent life is likely , communities of other beings may have been there for a very long time．
“If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago．
Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).
68. What is the article mainly about?
A. Other life forms coming to our planet．
B. Scientific evidence of other life forms．
C. Earth as the only place where human beings can survive．
D. Hawking’s belief that other life forms may exist in the universe．
69. Which of the following ideas is opposed to Hawking’s view?
A. Other life forms exist in the universe．
B. 0ther life forms may be more intelligent than human beings．
C. We should try to contact other 1ife forms from other planets．
D. Other life forms may exist in more than one part of the universe．
70. Paul Davies didn’t agree with Stephen Hawking ,believing that ________．
A. the universe is running out of resources
B. humans are the best creatures in the universe.
C. it is a good idea to avoid meeting with other life forms
D. Davies doesn’t think it proper to compare aliens with Columbus
71. Hawking referred to Christopher Columbus as an example to ____．
A. inspire interest in the universe
B. draw attention to other planets in the universe
C. warn people to watch out for other life forms
D. urge further exploration of the universe~

阅读下面的短文，请根据短文后的要求答题（请注意问题后的字数要求）
[1] If you are a recent social science graduate who has had to listen to jokes about unemployment from your computer major classmates, you may have the last laugh. There are many advantages for the social science major because this high-tech “ Information Age” demands people who are flexible (灵活的) and who have good______________.
[2] There are many social science majors in large companies who take up important positions. For example, a number of research studies found that social science majors have achieved greater managerial success than those who had technical training or pre-professional courses. Studies show that social science majors are most suited to change, which is the leading feature of the high speed, high-pressure, high-tech world we now live in.
[3] Social science majors are not only experiencing success in their long-term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry-level positions with social science graduates. The study also showed that the most sought-after (广受欢迎的) quality in a person who was looking for a job was communication skills, noted as “very important” by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.
[4] Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don’t regret their choice of study.
76. What’s the main idea of the passage? (Please answer within 10 words.)
_______________
