Night of the Living Ants

When an ant dies，other ants move the dead insect out of the nest．This behavior. is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead．

Dong-Hwan Choe，a scientist at the University of California，found that Argentine ants have a chemical on the outside of their bodies that signals to other ants，“I’m dead-take me away．”

But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead．

What keeps ants from hauling away the living dead？Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，“Wait-I'm not dead yet．” So Choe's research turned up two sets of chemical signals in ants：one says，“I'm dead，”the other set says，“I'm not dead yet．”

Other scientists have tried to figure out how ants know when another ant is dead．If an ant is knocked unconscious，other ants leave it alone until it wakes up．That means ants know that unmoving ants can still be alive．

Choe suspects that when an Argentine ant dies．the chemical that says“Wait-I'm not dead yet” quickly goes away．Once that chemical is gone，only the one that says“I'm dead”is left．“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new，unique chemicals after death，”said Choe．When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body．This was Choe's hypothesis(假设)．

To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹)． When the scientists used the“I'm dead”chemical，other ants quickly hauled the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．

The phrase“this death chemical”in paragraph 3 refers to

A．the chemical that contains poison．

B．the chemical that announces death．

C．the chemical that prevents death．

D．the chemical that causes death．

Questions are based on the following passage.

Cocoa contains chemicals calledflavanols （黄烷醇 ） that may help reduce the risk of strokes and heart attacks by lowering blood pressure and improving the body"s use of insulin （胰岛素 ） .

Washington chocolate producer Steve Kumar said that is one reason dark chocolate is increasingly popular among his customers. "A lot of people are attracted by dark chocolate because they just decide they love it， and they also have been reading all about the health benefits of dark chocolate，" said Kumar.

But those benefits have not been confirmed by studies involving large numbers of people. Also， during the production of chocolate， a lot of flavanols are destroyed， while sugar and fats are added to contribute to flavor.

Scientists now want to learn the benefits of flavanols in their pure form.

They plan a four-year study of 18，000 adults， who will take pills of pure cocoa flavanols， in what is being called the largest test of its kind. Jo-Ann Manson， of the Brigham and Women"s Hospital in Boston， is the lead researcher. "This pill of cocoa flavanols will avoid having the calories and the sugar and the fat found in chocolate，" said Manson. The pills also won"t have any taste. Participants，divided in two groups， will take two identical pills a day. One group"s pills will contain flavanols， while the others will getplacebo （安慰剂 ） pills. "The amount of chocolate that it would take in order to have this amount of cocoa flavanols would be more than ten times the amount that people would ordinarily eat，" said Manson.

Whatever the outcome of the study， Kumar said he"s not worried about his business. "People like the experience of actually biting into a piece of chocolate，whatever their favorites are，" he said.

The flavanol benefits test is still in the early stage， so scientists are not sure when the participants will be handed their first chocolate pills.

What chemical in cocoa may do good to the heart according to the passage？ 查看材料

A.Fat.

B.Insulin.

C.Sugar.

D.Flavanols.

y, eco-friendly rain gardens are healthy for the environment and the people living and working nearby.

A rain garden is not very different from a traditional garden. It is just a far more eco-friendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak(渗透) slowly into the ground before it runs into streams or enters the public drinking water supply.

Thus, a rain garden keeps the water，allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and eco-friendly “green” way to treat storm water.

What’s more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.

Native plants are recommended for rain gardens because they are more used to the local climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once native plants establish the necessary root system，they will require little care.

Often，local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don’t need to be a professionally environmental engineer to create a rain garden. As long as you’re eco­conscious homeowners，you can help the environment by building smaller rain gardens in your yards.

B-21.Which of the following is NOT true for the function of rain gardens？

A、They are good for living conditions.

B、They increase pollution.

C、They can beautify the community.

D、They improve the environment.

While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men, according to Dr. Yehuda, chief psychiatrist at New York''s Veteran''s Administration Hospital.

Studies of both animals and humans have shown that sex hormones somehow affects the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries （the female reproductive organs） removed, their chemical responses became equal to those of the males.

Adding to a woman''s increased dose of stress chemicals, are her increased opportunities for stress. It''s not necessarily that women don''t cope as well. It''s just that they have so much more to cope with, says Dr. Yehuda. Their capacity for tolerating stress may even be greater than men''s, she observes, It''s just that they''re dealing with so many more things that they become worn out from it more visibly and sooner.

Dr. Yehuda notes another difference between the sexes. I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family numbers, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating.

Adeline Alvarez married at 18 and gave birth to a son, but wad determined to finish college. I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better. Later her marriage ended and she became a single mother. It''s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck.

Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez''s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.

While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. “Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men,” according to Dr. Yehuda, chief psychiatrist at New York’s Veteran’s Administration Hospital.
