What will power your house in the future?Nuclear,wind,or solar power?According to scientists at the Massachusetts Institute of Technology (MIT) in the US,it might be leaves — but artificial (人造的) ones.

Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用).Now researchers have found a way to imitate this seemingly simple process.

The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂).Similar to natural leaves,it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell,which uses those two materials to produce electricity,located either on top of a house or beside the house.

Though the leaf is only about the shape of a poker card,scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.

The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf,by contrast,is made of cheap materials,easy to use and highly stable. In laboratory studies,Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.

The wonderful improvements come from Nocera's recent discovery of several powerful,new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now,the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides,the device can run in whatever water is available;that is,it doesn't need pure water. This is important for some countries that don't have access to pure water.

With the goal to “make each home its own power station” and “give energy to the poor”,scientists believe that the new technology could be widely used in developing countries,especially in India and rural China.

1.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?

a.artificial leaves split water into hydrogen and oxygen

b.the hydrogen and oxygen gases are stored in a fuel cell

c.the artificial leaves are put in water

d.the fuel cell uses hydrogen and oxygen to produce electricity

A.c,a,b,d B.c,b,a,d

C.b,c,a,d D.c,a,d,b

2.The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A.build up more power stations in the world

B.provide cheaper energy for developing countries

C.offer people in developing countries access to pure water

D.gain a deeper understanding of the photosynthesis process

3.The main idea of this passage is ________.

A.an introduction to the history of artificial leaves

B.a mixture of water power and solar energy

C.giving energy to the poor

D.an invention copying photosynthesis

An Extension of the Human Brain

Other people can help us compensate for our mental and emotional deficiencies (欠缺),much as a wooden leg can compensate for a physical deficiency. To be exact, other people can extend our intelligence and help us understand and adjust our emotions. When another person helps us in such ways, he or she is participating in what I’ve called a “social prosthetic (义肢的)system.” Such systems do not need to operate face-to-face, and it’s clear to me that the Internet is expanding the range of my own social prosthetic systems. It’s already a big bank of many minds. Even in its current state, the Internet has extended my memory and judgment.

Regarding memory: Once I look up something on the Internet, I don’t need to keep all the details for future use—I know where to find that information again and can quickly and easily do so. More generally, the Internet functions as if it were my memory. This function of the Internet is particularly striking when I’m writing; I’m no longer comfortable writing if I’m not connected to the Internet. It’s become natural to check facts as I write, taking a minute or two to dip into PubMed, Wikipedia, or other websites.

Regarding judgment: The Internet has made me smarter in matters small and large. For example, when I’m writing a textbook, it has become second nature to check a dozen definitions of a key term, which helps me dig into the core and understand its meaning. But more than that, I now regularly compare my views with those of many others. If I have a “ new idea,” I now quickly look to see whether somebody else has already thought of it, or something similar—and I then compare what I think with what others have thought. This certainly makes my own views clearer. Moreover, I can find out whether my reactions to an event are reasonable enough by reading about those of others on the Internet.

These effects of the Internet have become even more striking since I’ve begun using a smartphone. I now regularly pull out my phone to check a fact, watch a video, read weibo. Such activities fill the spaces that used to be dead time (such as waiting for somebody to arrive for a lunch meeting).

But that’s the upside (好处).The downside is that in those dead periods I often would let my thoughts flow and sometimes would have an unexpected insight or idea. Those opportunities are now fewer and farther between.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Both men and women are living longer these days in industrialized countries. 1. In general, they can expect to live six or seven years more than men. One reason for this is biological.

One important biological factor that helps women live longer is the difference in hormones between men and women. 2. Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

3. They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men. 4. Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman’s body cells have a tendency(向) to age more slowly than a man’s. Others think that a man’s body cells have a tendency to age more quickly. 5.

A.However, women, on average, live longer.

B .The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. Therefore, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control carious body functions.
