Recently,people in US education have gotten extremely worried because a new report has shown that American students have a math problem.
The 2015 Program for International Student Assessment（评估）(PISA) shows math scores in the US getting lower and no improvement in science or reading.PISA tests 15-year-olds from different countries and regions in their math,science and reading skills.About 540,000 students from 72 countries and regions took part in the assessment in 2015.
US scores in reading and science were about the same as three years ago,leaving Americans near the middle of the bigger group.But the situation in math is much more worrying.The US average score was 470,be;ow the OECD（经合组织）test average of 490,meaning the US was No.40 among the 72 countries and areas.It was 12 points lower than in 2012 and 18 points lower than in 2009.So,what is going on with American students' math skills?
One reason may be that the US does not teach math in enough depth."Students are often good at answering the first part of a problem in the United States,"said Andreas Schleicher,director of education and skills at OECD."But as soon as students have to go deeper and answer the more complicated part of a problem,they have difficulties."In comparison,many high-performing countries and regions in math teach a lot less but focus in much greater depth, especially when you look at East Asia,Japan and Singapore,according to Schleicher.
Another reason may be the fact that many people in the US are unwilling to travel to foreign countries to learn better teaching practices."One of our biggest challenges in the US is that the teachers are not going out and seeing what high-performing countries do differently,"said Wendy Kopp,who started Teach for America,in a news program.
1.When it comes to the 2015 PISA results,people in US education are more concerned about .
A. the US average score
B. the differences from the previous PISA
C. American students' performance in math
D. American students' situation in science and reading skills
2.What can we learn from the passage?
A. American students are not interested in simple math problems.
B. American students are unwilling to go abroad for further study.
C. American math teachers envy high-performing countries better teaching skills.
D. American math teachers seldom teach students how to solve complicated problems.
3.What is the main purpose of the passage?
A. To inform people of American students' 2015 PISA results.
B. To analyze the causes of American students' problems with math.
C. To stress the importance of learning math well to America students.
D. To give American math teachers some advice on how to teach math.

Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.
Susanna Rohm said she had experienced a parent’s worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. “I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的),” Rohm told a local newspaper. “Then I noticed that he looked like he wasn’t alive.” Indismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.
“I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, ‘Go and ask your parents to call 911,’” Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.
Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. “I was thinking we’d better give her a helping hand instead of getting scared,” Ethan said. “I told her to push on the baby’s chest five to ten times a minute with only two fingers, tilt back the baby’s head, plug the baby’s nose and breathe into the baby’s mouth,” Ethan said in an interview.
At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. “If the little boy hadn’t shown me what to do right there, my baby would probably not be alive right now,” Rohm said.
1.We can learn from Paragraph 1 that in the US, .

And women taking 48 in the study laughed more often when they were with a male friend than when they were with a(n) 49 friend or a male stranger. But men laughed more freely with friends of either sex than with strangers of either sex.
Scientists believe that the 50consumed in laughing 100 times is 51 to 15 minutes on an exercise bike. Another52 of laughter is53 it improves our mental health. Laughter reduces our levels of stress. It also helps us 54 serious illness.

Recently some American scientists have given a useful piece of advice to people in industrialized countries.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.1.

Stone Age people hunted wild animals for their meat, which had much less fat than domestic (驯养的) ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains. 4. We eat six times more salt than our ancestors and we eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.

Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
1.What is the main cause that people suffer from a lot of new sicknesses?
A. Ancient people did a great deal of physical exercise.
B. People today have a lot of alcohol.
C. People today have more tobacco.
D. Food today is quite different from that of ancient times.
2.Which of the following belongs to the dairy products?
A. Milk B. Corn C. Pork D. Flour
3. New kinds of sicknesses have been found because ________.
A. the human body has changed compared with humans who first appeared on the earth
B. the way we live has changed a little
C. our body can’t deal with the changes in life style
D. the way we live today is proper for the human body
4. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.
A. milk and other dairy products B. salt and sugar
C. wild animals, fresh wild vegetables and fruits D. grain foods
