Apparently，we are safe neither at home nor in the business office．We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects．These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house．They are released（set free）from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines．As the water is moving, these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that “new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation （通风）, these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools （carbon dioxide build-up ）, the factory work environment （ an endless list of potentially dangerous substances ）, and even home heating and cooling （the air conditioner may be our enemies, not our friends） have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that “there is no place like home.”

What is the main idea of the first paragraph?

A．The air we breathe in is harmful.

B．The water in everyday use is unsafe.

C．Chemicals are added to the drinking water.

D．Chemicals are released in the running water.

In Paragraph 2, the underlined sentence means that .

A．bathing should be done with caution

B．homes and offices should be aired often

C．any pollution should be taken into consideration

D．we should prevent any pollution from doing harm to us

What is the purpose of the passage?

A．To call on us to guard our water.

B．To show us that no place is like home.

C．To make us aware of the pollution around us.

D．To argue that neither homes nor offices are safe.

“How did you do it, Dad? How have you 21 not to take a drink for almost 20 years?” It took me almost 20 years to have the 22 to even ask my father this very 23 question. When Dad first 24 drinking, the whole family was on pins and needles 25 he got into a situation that, in the past, would have started him drinking again. For a few years we were 26 to bring it up for fear that the drinking would begin again.

“I had this little 27 that I would recite to myself 28 four to five times a day” was Dad’s 29 to my 18 – year – old unasked question. “The 30 were an instant relief and constant reminder to me that things were never so 31 that I could not handle them,” Dad said.

About a month after this talk with my father, I 34 a gift in the mail from a friend of mine. It was a book of affirmations（断言）with one affirmation listed for each 35 of the year.

I 36 opened the book to the page of my birthday to see what words of wisdom this book had in store for me. 37 of disbelief and appreciation rolled down my face. There, on my birthday, was the 38 poem that had helped my 39 for all these years! It is called The Serenity Prayer.

This is news on the Hour, Ed Wilson reporting. The president and First Lady will visit Africa on a goodwill tour in May. They plan to visit eight African countries.

Reports from Chinese want close ties between China and the US and Western Europe. A group of top Chinese scientists start in ten-nation tour next month.

Here in Miami, the mayor is still meeting with the leaders of the Teachers’ Union to try to find a way to end the strike. City schools are still closed after two weeks.

In news about health, scientists in California report findings of a relationship between the drinking of coffee and the increase of heart disease among women. According to the report in the American Medical Journal (杂志), the five-year study shows this: Women who drink more than two cups of coffee a day have a greater chance of having heart disease than women who do not.

In sports, the Chargers lost again last night. The BBS beat them 1 to nothing. The Wingers had better results. They beat the Rifles 7 to 3. It was their first win of their last five matches. That’s the news of the Hour. And now back to more easy listening with Jan Singer.

Recently scientists have worked out a way to judge roughly where a person has lived using strands(缕) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid（列阵）falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can establish a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a frame of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
“It’s not good for pinpointing (精确定位),” he said. “It’s good for ruling out many possibilities.”
64. What can we learn from the passage about the latest discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
65. What does the underlined word “identical” in paragraph 3 probably mean?
A. similar B. fantastic C. beneficial D. healthy
66. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.
