Like the body, the memory improves with use. Unlike the body, the memory can improve with

age.

For many years, doctors have been studying the way the brain works. We all know that the brain has two sides, the left and the right. The right side controls the senses (seeing, hearing, feeling, tasting and smelling), and is the creative and imaginative side. The left side of the brain controls our logical thinking. It processes the information which comes in, and puts it into order, We call the left side the "educated" side of the brain and generally, in western societies, people have developed this side of the brain more than the fight side.

Scientists believe that our brain will work much more efficiently if both the right side and the left side are developed equally. In many schools today, teachers try to educate the children in such a way that both sides of the brain are used. This can be done with logical subjects including mathematics and science as well as with creative subjects such as art and literature. The result achieved by students who are educated in this way is usually better than the result of students who are educated in a more traditional way. Traditional teaching tends to exercise the left side of the brain without paying very much attention to the development of the right side.

great thinkers such as Bertand Russell the Philosopher, and Albert Einstein, the scientist, only in their work, but also in creative and imaginative activities. It was because of their many different interests in life that they were able to achieve the full development of both sides of their brain.

As long as Einstein and Russell lived, their brains functioned efficiently. It was their bodies, finally, which could not go on any longer.

The body improves ______.

A．with age

B．with use

C．with memory

D．with development

Night of the Living Ants When an ant dies，other ants move the dead insect out of the nest．

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．

Teenagers are different from people of other age grou

ps. The differences can be 18) from how they behave. In fact, the brains of teenagers are very different from those of children or adults.

According to this theory, teenager behaviors like risk-taking, a lack of sensitivity to how their actions 20)both themselves and others, increased aggressive deeds, 21) concentration and a negative attitude were thought to be due to bad parenting or changes in body chemistry.

However, new technology has allowed researchers to examine the healthy brain at work. What they have discovered is something 22) : Not only does the brain continue to grow beyond the age of three, but the research also23) that the brain of a teenager is larger than that of an adult.

As teen brains are 24) with chemicals during adolescence phase, the brain grows. However, only the cells that are used the most will 25) the competition within the brain. Those that are used less begin to die off until the brain reaches what will be its adult size.

The way that teens spend their time 26) influences which connections remain and which disappear. On the basis of this knowledge, experts advise parents to be 27) on how their teenagers spend their time. What teens do today will affect their brains for the rest of their lives.

A) diminished

B) demonstrated

C) alert

D) radical

E) surrender

F) survive

G) affirms

第3题

Look at a man walking down a street or road in' the sunlight and you will see his shadow.

If you watch two men walking in the sunlight and carrying a six-fool pane(窗玻璃片) of glass between them, you will see each man six feet apart, but there will be no shadow of the pane of glass.

Shadows are easily explained since we know that light travels in a straight line. We also know that light waves pass through some bodies and not through others.

When light strikes a body and passes through it unchanged, we call such a body or material transparent. Most glass is such a material, especially window glass, and it is for this reason that we do not see the shadow of the window pane which the men are carrying. Do you know of any other transparent materials？ The most common one, with which we are familiar, is air. Another is clear water.

On the other hand, some materials do not let light pass through them at all. They stop the light waves just as you would-catch a ball that was being thrown to someone standing between you. Such materials are called opaque. Men' s bodies, like steel, rock, concrete or even cardboard, are opaque and do not permit the light to pass through. An opaque body casts a shadow.

The title that best expresses the ideas of the passage is ______.

A．Why are there shadows

B．The transparent materials

C．How to cast a shadow

D．Shadows and light waves
