We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.
A brain can also simply be a smart person, If a person is called brainy, she is smart and intelligent. If a family has many children but one of them is super smart, you could say, "She's the brains in the family." And if you are the brains behind something you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.
Brain trust is a group of experts who give advice. Word experts say the phrase "brain trust" became popular when Franklin D. Roosevelt first ran for president in 1932, Several professors gave him advice on social and political issues facing the US. These professors were called his "brain trust."
These ways we use the word "brain" all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain." As a verb to drain means to remove something by letting it flow away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.
However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.
If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

It is nice to know what the weather will be like when we plan a trip. Do you know anything about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back.
It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.
Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand — no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why?
A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.
In this example studying tree rings uncovered an exciting fact about the history of man.
1.We can find out the weather of five years ago by counting the rings of a tree trunk ____.
A. from the left to the right
B. from the right to the left
C. from the inside to the outside
D. from the outside to the inside
2.If the ring was far from the others, we can conclude that the weather of that year was ______.
A. bad B. sunny C. favorable D. rainy
3.By studying the rings of dead trees in an area of New Mexico, the scientist found _______.
A. why the people had to leave
B. where the people had to go
C. what the people had to eat
D. how the people left
4.The ancient people usually lived where there were plenty of trees mainly because ______.
A. trees provided an exact record of weather for research
B. trees could supply them with fruit and food to live on
C. trees could supply them with shades
D. trees were materials for fires and buildings
5.By giving the example of an area of New Mexico, the author tries to prove .
A. trees can’t live in the area without population
B. that studying trees is important for the history of man and weather.
C. what the real relation is between tree rings and the history of man and weather
D. the history of man is important for the history of trees

We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?
According to Time, of course not, taste has little to do with quality of water.
According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.
“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”
People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.
However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.
With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.
And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.
Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.
1.The purpose of the first paragraph is to ________________.
A. show an example B. draw a conclusion
C. analyze a phenomenon D. introduce a topic
2.Which of the following may Truls Krogh agree?
A. If the water tastes different, we shouldn’t drink it.
B. The water held in a clean container is likely safe to drink.
C. Although kept fresh, water may still have much organic matter.
D. Covered water can last for a thousand years.
3.What can we infer from the passage?
A. BPA does little harm to our health.
B. Tap water is always safe to drink.
C. Microorganisms are easy to produce in the heat.
D. Disposable plastic bottles have been banned already.
4.What can be the best title of the passage?
A. Why Water is Tasteless B. How to Get Clean Water
C. Does Water Really Go Bad? D. Learn to Protect Water

There is nothing in the Hippocratic Oath that tells doctors what to do when they make a mistake with a patient. Nor is there much on this subject in medical school curriculums or in training programs.
But there should be.
Much was made of the Institute of Medicine’s 1999 report that 44,000 to 98,000 people die each year in hospitals from preventable medical errors, many of them made by doctors.
The report stated much first-hand information to address the problem, but there was little discussion about how doctors, when they have made mistakes, should deal with their patients,
Everyone assumes that the ever-present threat of accusation has made doctors more anxious about admitting error, and no doubt it has, But doctors have always been tight-lipped about their mistakes, in part to preserve an illusion(幻觉,错误的信仰) of medical omnipotence(全能)
Studies suggest that patients are less likely to accuse doctors when they apologize for mistakes, and many hospitals now encourage their physicians to admit their errors. According to an supportive group called The Sorry Works! Coalition, 16 states have already passed laws giving doctors legal immunity(饶恕) for their apologies to patients.
Of course, there are plenty of doctors with a nice bedside manner who can get away with bad treatment. How else to explain patients who often line up in court to support doctors accused of malpractice(失职)?
The surprising truth is that many patients have a hard time knowing whether they are really getting good medical care.
Because so many diseases change randomly over time, patients sometimes spontaneously(自发的) improve despite improper treatment. On the other hand, a patient who receives exemplary medical care may fare badly(情况不好) simply because the illness is hard to treat. In other words, doctors are often praised or blamed, when the outcome is in fact a chance event.
Many, perhaps even most, medical errors probably have little ill effect and go unnoticed by patients. Many lawyers would disagree, but doctors ought to let their patients know when they’ve made a mistake; it humanizes them and builds trust.
1.According to the passage, which of the following is TRUE?
A. The doctor made the mistake deliberately so they do not apologize.
B. Doctors never tell the patient they have made a mistake.
C. The patients won’t forgive the doctor if he make the mistake.
D. The patient will usually forgive the doctor when the mistake are not intentional.
2.What does the sentence “But there should be” mean in the second paragraph?
A. But there should be more subjects in medical school.
B. But there should be something more specific in the Oath.
C. But the doctor should not make any mistake.
D. But there should be something to tell the doctor what to do when they make a mistake.
3.What is the author’s attitude toward the opinion that the doctor should apologize when he makes a mistake?
A. Supportive B. Critical
C. Indifferent D. Neutral
