回答题：

Looking to help the environment？ Consider the following simple ideas.

Turn off electrical devices when they"re not being used.

Turning off， rather than leaving on stand-by， things like your TV and computer will save huge amounts of energy. With this， we can all help reduce the amount of carbon dioxide emitted into the earth"s atmosphere， thereby reducing pollution and global warming.

Share your ear.

Rather than traveling to work alone， why not arrange ear-sharing with one or more of your，friends or colleagues？ To give you an example， if you drive a fashionable ear， you will use more energy in a year than you would leaving your fridge open for seven years， or your TV on for thirty-two years ! Imagine the savings if you shared your ear with 2，3 or even 4 other people !

Refuse junk mail.

While we all complain about how much junk mail we get， we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin——with 99% of it not even opened. What can you do about this？ There are various websites where you can register to receive no junk mail. As well as saving time， you"ll also be doing a lot for the environment. Each year，100 million trees are used to produce junk mail.250，000 homes could be heated with one day"s supply of junk mail.

There are many other everyday changes you can make to help the environment. They will cost you nothing， and many will actually save you money! Why not give it a try？ We can all help，if we really want to.

By turning off a TV or computer that‘s not being used，you will save a lot of energy. 查看材料

Help Your Child Become a Reader

Encouraging early reading skills can build a path to a lifelong (终身的 ) love of reading and can help your child get a head start in school. While reading to your child is still the most important thing you can do to build reading skills, there are many techniques that can help.＜br＞

Make reading fun. Play games with your child as you read. Many traditional children&39;s games can be adapted to encourage reading skills.＜br＞

While reading or during play, tell your child, "I spy with my little eye, something that begins with the letter b." Help the child find something on the page or in the room that begins with that letter. For example, "I see a barn." This can also be used to teach beginning letter sounds. "I spy with my little eye.＜br＞

Something that begins with the sounds." Help the child find a word that begins with the "s" sound.＜br＞

In this variation on the popular game, instruct the child that, "Simon says, &39;point to something that starts with the letter n&39;." The child can then find an object in the room or a body part, such as the nose,that starts with the letter presented. This can also be used to teach beginning sounds.＜br＞

Make a game out of rhyming (押韵) words by making up silly words to rhyme with the child&39;s name or favorite toys. This sets the stage for rhyming real words by showing the child the similarities of sounds. As the child masters making up the words, begin rhyming real words to one another.＜br＞

Tips to raise a successful reader:＜br＞

Put books in places where the child plays. If books are easily accessible, children are more likely to pick them up.＜br＞

Let children "read to you" by looking at pictures. Making up stories to go along with illustrations helps children discover how words relate to pictures.＜br＞

Take books along on trips or even short visits to the doctor&39;s office or grocery store.＜br＞

Have children help you shop. Reading grocery lists and looking for specific items help build sight vocabulary.

A good reading habit can help your child do well at school. 查看材料

请根据短文的内容，回答题。

Intelligent Machines

(1) Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson&39;s disease, but in what other ways might computer technology be able to help us？ Ray Kurzweil is author of the successful book The Age of Intelligent Machines and is one of the world&39;s best Computer research scientists. He is researching the possibilities.＜br＞

(2) Kurzweil gets computers to recognize voices. An example of this is Ramona, the virtual (虚拟的 ) hostess of Kurzweil&39;s homepage, who is programmed to understand what you say. Visitors to the site can have their conversations with her, and Ramona also dances and sings.＜br＞

(3) Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a"seeing machine". "This will be like a friend that could describe what is going on in thevisible world," he explains. Blind people will use a visual sensor (探测器) which will probably be built into a pair of sunglasses. This sensor will describe to the person everything it sees.＜br＞

(4) Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will be able to translate into other languages, so even people without heating problems are likely to be interested in using it.＜br＞

(5) But it is not just about helping people with disabilities. Looking further into the future,Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won&39;t be ready for at least 50 years, but when it arrives, it means our mind will be able to live forever.

A.A new pair of ears

B.Computers that can communicate

C.Everlasting consciousness on a computer

D.Time to break off a friendship

E.An author and researcher

F.A new pair of eyes

Bringing Nanotechnology to Health Care for the Poor

Nanotechnology uses matter at the level of molecules and atoms. Researchers are finding different uses for particles with a length of one nanomcter, or one-billionth of a meter, These include things like beauty products and dirt-resistant clothing. But one area where many experts believe nanotechnology holds great promise is medicine.＜br＞

Last week, speakers at a program in Washington discussed using nanotechnology to improve health care in developing countries. The program took place at the Woodrow Wilson International Center for Scholars. Peter Singer at the University of Toronto says a nanotechnology called quantum dots could be used to confirm cases of malaria. He says it could offer a better way than the traditional process of looking at a person&39;s blood under a microscope.＜br＞

In poor countries, this process is often not followed. As a result, sick people may get treated for malaria even if they do not have it. Such misuse of medicines can lead to drug resistance.＜br＞

Quantum dots are particles that give off light when activated. Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule.＜br＞

Experts say nanotechnology shows promise not just for diagnosing diseases, but also for treating them. Piotr Grodzinski of the National Institutes of Health talked about how nanotechnology could make drugs more effective. He talked about cancer drugs already developed with nanotechnology. He says if a drug can target a cancer locally in the body, then much less of it might be needed, and that means lower side effects.＜br＞

Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the Woodrow Wilson Center. He noted that Brazil, India, China and South Africa are currently doing nanotechnology research that could help poor countries. But he also noted that there is some risk in using nano-materials. He says nanometer-sized particles behave differently in the body and the environment compared to larger particles. Experts say more investment in research is needed to better understand these risks.

Which of the following uses ofnanotechnology is NOT mentioned in the passage？查看材料

A.make beauty products and dirt-resistant clothing

B.To produce better and lighter building materials

C.help more accurately diagnose diseases

D.To help more effectively treat diseases

根据以下材料，回答题。

Ants as a Barometer of Ecological Change

At picnics.ants are pests.But they have their uses.In industries such as minin9，farming and forestry.they can help gauge（测定）the heahh of the environment by just crawling around and being antsy（坐立不安）.

It has been recognized for decades that ants——which are highly sensitive to ecological change——can provide a near—perfect barometer（气压计）of the state of an ecosystem.Only certain species，for instance，will continue to thrive at a forest site that has been cleared of trees. （46）And still others will move in and take up residence.

By looking at which species populate a deforested area，scientists can determine how “stressed”the land is （47）Ants are used simply because they are SO common and comprise（构成）SO many species.

Where mine sites are being restored，for example，some ant species will recolonize（重新移居到……）the stripped land more quickly than others. （48）Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.

Ant surveys also have been used with mine.site recovery projects in Africa and Brazil，where warm climates encourage dense and diverse ant populations.“We found it worked extremely well there.”says Jonathan Major，a professor of environmental biology.Yet the surveys are perfectly suited to climates throughout Asia，he says，because ants are so common throughout the region.As Major puts it.“That，s the great thing about ants.”

Ant surveys are SO highly regarded as ecological indicators（指示器）that governments world-

wide accept their results when assessing（评估）the environmental impact of mining and tree har-

vestin9.——（49）.

Why not？Because many companies can"t afford the expense or the laboratory time needed to

sift（详审）results for a comprehensive survey.The cost stems，als0，from the scarcity（缺乏）of

ant specialists.——（50）

请在第__（46）__处填上正确答案。查看材料

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses，such as farming and property development，ant surveys aren"tused widely.

C.Employing those people are expensive.

D.They do this by sorting the ants，counting their numbers and comparing the results withthose of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

A．The difference between being a manager and being a leader is simple． Management is a career．Leadership is a callin9．You don’t have to be tall， well—spoken and good looking to be a successful leader．You don’t have to have that“special somethin9”to fulfill the leadership role．
