According to John C. Davis, writing in E / The Environmental Magazine, just about any homeowner can collect rainwater, given that the roof and gutters do most of the work. And since an inch of rain falling on a 2,000-square-foot roof produces some 1,200 gallons of water, you can harvest enough to water your lawn or garden.
Plants and grass actually do better when fed rainwater instead of tap water, which is usually treated with substances that can hold back plant growth. Using rainwater can also extend the life of pipes, since the salts added to tap water may gradually damage the pipes. However, homeowners should set up a water purification system if they do plan to use rainwater for inside needs.
Rainwater harvesting can also be good for the local community, as it reduces the erosion, flooding, and pollution associated with heavy rainfall, and reduces dependence on public water supplies. So some states fund rainwater collection systems in their local communities.
Many varieties of rain barrel(桶) systems, starting at just $100, are available for home use. A typical setup is simply a rain barrel positioned under a gutter’s downspout. Skillful homeowners can make their own water harvesting systems, but buying one is a lot easier. Most garden centres offer a range of choices as well as tips.

Here the question is about how we define intelligence itself. The answer appears to be interesting, because the evidence from psychological studies suggests that much of our intelligence comes from how we coordinate ourselves with other people and our environment.
An influential theory among psychologists is that we"re cognitive misers(认知吝啬者). This is the idea that we are unwilling to do mental work unless we have to. We try to avoid thinking things fully when a short cut is available. If you"ve ever voted for the presidential candidate(总统候选人) with the most honest smile, or chosen a restaurant based on how many people are already sitting in there, then you are a cognitive miser. The theory explains why we"d much rather type a zip code into Google Maps than memorize and recall the location of a place – it"s so much easier to do so.
Research shows that people don"t tend to rely on their memories for things they can easily access. Buildings can somehow disappear from pictures we"re looking at, or the people we"re talking to can be changed with someone else, and often we won"t notice – a phenomenon called “change blindness”. This isn"t an example of human stupidity – far from it, in fact – this is an example of mental efficiency. The mind relies on the world as a better record than memory.
Philosophers have suggested that thinking is really happening in the environment as much as it is happening in our brains. The philosopher Andy Clark called humans "natural born cyborgs(电子人)", those naturally capable of absorbing and combining new tools, ideas and abilities. In Clark"s view, the route to a solution is not the issue – having the right tools really does mean you know the answers, just as much as already knowing the answer.
Rather than being forced to rely on our own resources for everything, we can share our knowledge. Technology keeps track of things for us so we don"t have to, while large systems of knowledge serve the needs of society as a whole. I don"t know how a computer works, or how to grow vegetables, but that knowledge is out there and I can get to benefit. The internet provides even more potential to share this knowledge. Wikipedia is one of the best examples – an increasingly large database of knowledge from which everyone can benefit.
So as well as having a physical environment – like the rooms or buildings we live or work in – we also have a mental environment, which means that when I ask you where your mind is, you shouldn’t point toward the centre of your forehead. As research shows, our minds are made up just as much by the people and tools around us as they are by the brain cells inside our skull.

All the babies died before the first year. But clearly there was more than language deprivation (剥夺，丧失). What was missing was good mothering. Without good mothering, in the first year of life especially, the ability to survive is seriously affected.
Today no such extreme deprivation exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to signals of the baby, whose brain is programmed, to mop up language rapidly. There are critical times, it seems when children learn more rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again.
Linguists suggest that speech milestones are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ.
Recent evidence suggests that a baby is born with the ability to speak. What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a teddy bear with the sound pattern “teddy bear”.
But speech has to be developed, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child’s babbling, clinging, grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals reduces the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s nonverbal (非语言的) signals is basic to the growth and development of language.
小题1:Frederick’s experiment was extreme because _________.
| A．he wanted to prove children are born with ability to speak |
| B．he wanted his nurses to say another language |
| C．he was unkind to the nurses |
| D．he ignored the importance of mothering to the babies |
| A．they do not listen carefully to their mothers |
| B．their mothers do not respond to their attempts to speak |
| C．their brain has to absorb too much language at once |
| D．their mothers are not intelligent enough to help them |
| A．difficult periods in the child’s life |
| B．moments when the child becomes critical towards its mother |
| C．important stages in the child’s development |
| D．times when mothers often neglect their children |
| A．have a high IQ | B．be less intelligent |
| C．not necessarily be backward | D．be insensitive to verbal signals |
| A．the child will be able to speak properly |
| B．the child will continue to give out signals |
| C．the child will invent a language of own |
| D．the child will make little effort to speak |
Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to live indefinitely. The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing.
Another new area of research involves the oxidation（氧化） theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young.
Perhaps the most immediate advance we are likely to see in the battle to halt（停止）the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing injured bones or even organs like livers and kidneys with ones “grown” in laboratories. By 2050 perhaps every organ in the body, except the brain, will have become commercially available. Recent experiments also show that it may one day be possible to “grow” new organs inside our body to replace worn-out ones, something which lizards and alligators already do.
Suddenly immortality（不死，不朽） seems within reach. We can begin to imagine a future where we are born, we grow to maturity, but we never grow old and die. But do we really want to live forever?
小题1: When all humans reach a certain age, .
| A．they suffer the effects of their diet and lifestyle |
| B．the organs stop to perform appropriately |
| C．their cells continue to renew themselves |
| D．they develop arthritis and Alzheimer’s |
| A．alligators are in danger in the wild because of the threat from man, pollution and other animals |
| B．it is widely accepted that humans have a fixed lifespan |
| C．there exists an age gene which may control ageing |
| D．the age gene damages the body |
| A．live for a period of time without a fixed end |
| B．live without a clear aim |
| C．live in an uncertain way |
| D．live without being fully grown |
| A．by 2050 we might have most of our worn-out organs replaced with new ones commercially |
| B．never can the ageing process be avoided |
| C．livers and kidneys are sure to be grown in laboratories by the year 2020 |
| D．lizards and alligators grow new organs inside their body to replace worn-out ones |
| A．DNA researches show how our cells renew themselves. |
| B．Anti-oxidants are likely to play an important part in keeping people young. |
| C．How our biological clock works? |
| D．Eternal（永恒的） youth: new developments in anti-ageing research. |
| A．a future where we are born, we grow to maturity, but we never grow old and die is on its way |
| B．he is uncertain whether we can live forever |
| C．it remains to be seen whether immortality is a blessing or a curse |
| D．immortality is no longer a dream |
It’s a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. She co-wrote the review paper with Nichole R.Lighthall. “This is sort of not what people would think, ” Mather says. “Stress is usually associated with negative experiences, so you’d think, maybe I’m going to be more focused on the negative outcomes.”
But researchers have found that when people are under stress, they start paying more attention to positive information and discounting negative information. “Stress seems to help people learn from positive feedback and impairs（削弱）their learning from negative feedback, ” Mather says.
When people under stress are making a difficult decision, they may pay more attention to the good sides of the alternatives they’re considering and less to the problems. So someone who’s deciding whether to take a new job and is feeling stressed by the decision might focus on the increase in salary more than the longer commute（上下班往返）.
The increased focus on the positives also helps explain why stress plays a role in addictions. People under stress have a harder time controlling their urges. “The compulsion to get that reward comes stronger and they’re less able to resist it,” Mather says. A person who’s under stress might think only about the good feelings they’ll get from a drug, while the downsides shrink into the distance.
Stress also increases the differences in how men and women think about risk. When men are under stress, they become even more willing to take risks; when women are stressed, they get more conservative(保守的). Previous research backs this up — men usually react to difficulties while trying to fight them or escape them; women try to find friends and improve their relationships.
小题1:By saying “You might want to hold off on that” in the first paragraph, the writer suggests that .
| A．you might want to delay making your big decision |
| B．you should save the presentation for later |
| C．you should avoid taking risks |
| D．you might benefit from the stress |
| A．often leads people to take more risks |
| B．often leads people to make balanced decisions |
| C．makes people think more of negative results |
| D．makes people ignore the negative side of problems |
| A．Stress is helpful in getting rid of addictions. |
| B．People who are addicted to drugs are easily stressed. |
| C．When women are stressed, they do not tend to take risks. |
| D．When men are stressed, they are more likely to develop an addiction. |
| A．Stress can affect decision-making. |
| B．Stress increases our desire to get rewards. |
| C．We should think more about the upside of problems. |
| D．There is a link between stress and negative experiences. |
Whales are not fishes but mammals (哺乳动物). Their body temperature stays the same, and does not change with the temperature of their environment. They breathe air, so they have to come out of the water to get oxygen. Thus, they cannot afford to fall into a sleeping state for too long, since they need to be awake in order to breathe. It is thought that only half of their brains sleep at a time, so that whales are never completely asleep. Females give birth to the young. They have hair. Although they are not covered in hair or fur like many mammals, whales have some bristles (胡子), usually on their heads.
Whales are highly social animals with complex languages and intelligence. They communicate with each other using romantic sounds, called “whale songs”. Being so large and powerful, these sounds are also loud.
Whales are endangered as a result of whaling (捕鲸) from the eleventh century to the twentieth. It has attracted the attention of environmentalists and some measures (措施) have been taken to protect whales.
小题1:How many aspects show that whales are mammals?
| A．One. | B．Two. | C．Three. | D．Four. |
| A．whales can breathe in the water |
| B．if a whale sleeps too long, it will get drowned |
| C．in order to breathe, whales never sleep |
| D．whales give birth to the young on the land |
| A．By body language. | B．By speaking languages. |
| C．By making song-like sounds. | D．By giving off a smell. |
| A．Whales are cold-blooded mammals like fishes. |
| B．Whales are hunted for food by people. |
| C．Whales are very harmful to human beings. |
| D．Whales are in danger because of being killed by people. |
