It is very important for people to drink water in our everyday life. Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why? Because that is what they have been told all their life. But a recent report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking. The report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, part of the National Academies. The report contains some general suggestions. The experts say women should get about 2.7 liters of water daily. Men should get about 3.7 liters. But wait——in each case, that is more than eight glasses.
There is one important difference. The report does not tell people how many glasses of water to drink. In fact, the experts say it may be impossible to know how many glasses are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods. People do not get water only by forcing themselves to drink a set number of glasses per day. People also drink fruit juices and sodas and milk. They drink coffee and tea. These all contain water. Yet some also contain caffeine. This causes the body to expel(排出)more water. But the writers of the report say this does not mean the body loses too much water.
As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need two times as much water as others do. All this, however, does not answer one question. No one seems sure why people have the idea that good health requires eight glasses of water daily.
It may have started with a misunderstanding. In 1945, the National Academy of Sciences published some guidelines. Its Food and Nutrition Board(营养膳食) said a good amount of water for most adults was 2.5 liters daily. This was based on an average of one milliliter(毫升)for each calorie of food eaten. But that was only part of what the board said. It also said that most of this amount is contained in prepared foods.
1.In experts’ opinion, every day a person should drink ____.
A. as much water as he can B. more than eight glasses of water
C. according to actual need for his body D. when he comes in sight of water
2.What is mainly described in the second paragraph?
A. People know about the daily water requirement.
B. People need water instead of all kinds of drink.
C. People get daily water not only from drinking.
D. People drink all kinds of drink every day.
3.Who might drink less water according to the third paragraph?
4.The main purpose of writing the texts is to _______.
A. make a good suggestion of drinking daily B. make clear the requirements to drink daily
C. tell the importance of drinking water daily D. figure out a good amount of water daily

For high school leavers starting out in the working world, it is very important to learn particular skills and practice how to behave in an interview or how to find all internship(实习). In some countries, schools have programs to help students onto the path to work. In the United States, however, such programs are still few and far between.
Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.
In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized (批评)education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country’s most vulnerable(易受影响的)kids with no jobs and no skills.
Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school. James Madison High School in New York, for example, encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they’re still at high school.
However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US, unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row. “The risk is that if teenagers miss out on the summer job experience, they become part of this generation of teens who had trouble in landing a job,” said Michael, a researcher in the US.
1.What’s the main idea of the text?
A.The lack of career-based courses in US high schools.
B.Tips on finding jobs for high school leavers.
C.Arguments about recent US education reform.
D.Advice for American high school leavers.
2.According to Robert Schwartz, _________.
A.there is no need for kids to go for higher education in the US
B.students should get contact with the working world at high school
C.education reform should focus on students’ performance in exams
D.teenagers in the US can’t miss out on the summer job experience
3.The underlined word “daunting” in Paragraph 6 most probably means __________.
A.creative B.interesting C.discouraging D.unbearable
4.What can be inferred from the text?
A.High school leavers with no practical skills can’t find a job at all.
B.Students with career-based courses never have problems finding a job.
C.US companies work with schools to prepare young people for future employment.
D.Unemployment rates for US teenagers remain high at the moment.

Time is very important in our lives. It organizes our everyday moments. However, time never had any importance in my life until I received a watch from my father.
I received this gift on a cloudy day. I had to go to the airport at 9:00 a.m. to meet my uncle and take him to my father’s house. However, I was late because I was staying with my friends. Later on that day, around 11:00 a.m., I remembered my uncle, but I was very late for him. He had left the airport and taken a taxi to my father’s house.

“Yes, Dad, and I’m sorry about not meeting my uncle at the airport.”
“I hope today you learned something important, and this watch will be a reminder (提醒物) for you.” He told me to take this watch and use it as an organizer of my life.
