Eating too much fatty food，exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure（暴露）to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can cause heart attack or stroke（中风） within as little as a few hours after exposure. In one report of the research, scientists found that people exposed to high levels of pollutants（污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. Another study of stroke patients showed that even air that the U.S. Environmental Protection Agency（EPA）considers to be of “moderate”(良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health. The text mainly discusses the relationship between _________.
| A．heart problems and air quality | B．heart problems and exercising |
| C．heart problems and smoking | D．heart problems and fatty food |
The underlined word “modest” in Paragraph 3 most probably means _________ .
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
We can learn from the text that __________？
| A．eating fatty food has immediate effects on your heart. |
| B．the EPA conducted many studies on air quality. |
| C．moderate air quality is more harmful than smoking. |
| D．stricter regulations on pollutants should be made. |
The author’s purpose of writing the text is most likely to _________ .
| A．inform | B．persuade |
| C．describe | D．entertain |

Inventor，physicist，surveyor，astronomer，biologist，artist…Robert Hooke was all these and more．Some say he Was the greatest experimental scientist of the 17th century．In the course of his work，he cooperated with famous men of science like Isaac Newton，and the great architect, Chrish@ler Wren．
Hoocke's early education began at home，under the guidance of his father．He entered Westnfinster School at the age of 13，and from there went to Oxford，where he came in contact with some of the best scientists in England．Hooke impressed them with his skills at designing experiments and inventing instruments．In 1662，at the age of 28, he was named Curator of
Experiments at the newly formed Royal Society of London—meaning that he was responsible for demonstrating new experiments at the society’s weekly meetings．Hooke accepted the job，even though he knew that the society had no money to pay him!
Watching living things through a microscope was one of his favorite pastimes．He invented a compound microscope for this purpose．One day while observing a cork(软木塞)under a microscope，he saw honeycomb-like structures．They were cells—the smallest units of life．In fact，it was Hooke who invented the term“cell” as the boxlike ceils of the cork reminded him of the cells of a monastery(修道院)．
Another achievement Of Hook’s was his book Micrographi which introduced the．Enormous potential of the microscope．It contains fascinating drawings of the things he saw under the microscope．The book also includes，among other things，ideas on gravity，light and combustion(燃烧)that may have helped scientists like Newton when they were developing their own theories on these phenomena．
Hooke made valuable contributions to astronomy too．A crater(坑)on the moon is named after him in appreciation of his services to this branch of science．
68．Why possibly did Hooke accept the job as Curator of Experiments?
A. Because his parents couldn’t afford his education．
B．Because his family needed his support．

After my husband died suddenly from a heart attack，my world crashed around me．My six children were all under 10，and I was burdened with the responsibilities of earning a living，and caring for the children．I was fortunate to find a wonderful housekeeper to care for the children during the week，but from Friday nights to Monday mornings，the children and t were alone．
One Friday evening I came home from work to find a big pretty German shepherd off our doorstep．This dog seemed to intend to enter the house．The children liked “German” immediately and begged me to let him in．I agreed to let him sleep in the basement．That night I slept peacefully for the first time in many weeks．
The following morning we made phone calls and checked lost-and-found ads for German’s owner, but with no results．
On Sunday I had planned to take the children on a picnic．Since I thought it best to leave German behind in case his owner came by，we drove off without him．When we stopped to get gas, we were amazed to see German racing to the gas station after us．No way was he going to be left behind．
Monday morning I let him out for a run．He didn’t come back and we were all disappointed．
We were convinced that we would never see him again．We were wrong．The next Friday evening,
German was back on other doorstep．Again he stayed until Monday morning，when our housekeeper arrived．
This pattern repeated itself every．weekend for almost 10 months．We grew more and more fond of German．We took comfort in his strong，warm presence，and we felt safe with him near us．
As German became part of the family，he considered it his duty to check every bedroom to be sure each child was cozy in bed．
Each week，between German’s visits，I grew a little stronger，a little braver and mole able to cope；every weekend we were no long alone and enjoyed his company．Then one Monday morning we patted him on his head and let him out for what turned out to be the Iast time．We never saw German again．

My dad also taught me，by example，that a healthy lifestyle is important．He was hardly ever sick．But I don’l think my dad ever even had a cup of coffee．He barely touched alcohol．
He would say，“Boonnie，your voice is a reflection of your overall physical well-being．So if you want to sing well，take better care of yourself.” If I became hoarse(嘶哑)or caught a cold，he didn’t blame me directly：“Well，Bonnie，you know，if you’d get to sleep a little earlier，that would probably be a good idea．”When I decided to get unexcitable about 18 years ago，he told me．“See，
Bonnie，it's so great to see you in such strong voice all the time．”
He just did not complain，even when he was uncomfortable toward the end，from the pneumonia that eventually took his life．He simply made a choice to be positive and not negative．
I am so glad that we had the chance to perform together．I was touched that he tried singing my music，even though the bluesy style didn’t come naturally to him．Then，when I had so much
Grmnmy success with my album Nick of Time in 1990，I realized. Hey，I have one of the greatest singers of all time in my family．I was very nervous about doing the Boston Pops show on TV with my dad．To calm me，he said，“Bonnie，a beautiful song is a beautiful song．Just believe it．”I looked in my dad’s eyes，and there we were singing the Irving Berlia song with the lvric．Of all the duets I've done．that one wiU always be a highlight．
