As an effect of the high fuel prices spent on bus transportation, some American schools are changing to a four-day week. That means longer days instead of the traditional Monday through Friday schedule.
Having been approved for three years and beginning in the fall, students in the Maccray school district in Minnesota will be in school from Tuesday to Friday. Each school day will be 65 minutes longer. Officials say the district expects to save about sixty-five thousand dollars a year in transportation costs.
In new Mexico, the first school district changed to a four-day week in 1974 because of the Arab oil boycott(抵制). Now, 17 out of 89 districts use it.
In Custer, South Dakota, students have been going to school four days a week since 1995. Superintendent Tim Creal says the change has saved about one million dollars over just the past eight years. He sees other benefits, too. Students get more instructional time, and activities that used to take up class time are now held on non-school days. He says that in the future, the growth of online classes could make it possible to require even fewer days in school. High fuel prices are driving college students to take more online classes.
A four-day school week sounds like a great idea for students and teachers, but working parents may have to pay for child care for that fifth day.
【小题1】According to Tim Creal, what makes it possible to have even fewer days in school?
| A．The increasing number of private tutors.(私人教师) |
| B．The development of teaching methods. |
| C．The increase in the number of online classes. |
| D．The growth in the income of Americans. |
| A．students will be in school from Monday to Tuesday. |
| B．four-day week was first carried out in South Dakota. |
| C．Maccray will save one million dollars every year. |
| D．Minnesota state has approved the four-day week plan |
| A．some school’s four-day week plan | B．districts using a four-day week. |
| C．how to save on transportation fees. | D．expense of school transportation. |

As a kid, I can remember going to the supermarket and grabbing eggs off the shelf. I would run them home to my mother because they were usually going into a delicious cake. Times have changed. Cage-free? Organic? Brown? White? Omega-3s(一种脂肪酸)?Help! Here are some tips to help you figure out which eggs you should be eating.
Brown or white? In fact, color is simply a sign of the breed of hen. Find the freshest egg with the most flavor and let color be a secondary concern.
Extra Omega-3s? Omega-3 eggs come from a hen whose diet has added flaxseed (亚麻籽)，which produces an egg containing an average of 225 mg of Omega-3 fatty acids and vitamin E. The countless health benefits for humans make these eggs an attractive purchase. My opinion? Eat a piece of fresh fish and get a pure pill of Omega-3s. Let eggs be eggs.
Does your egg need exercise? Free-range eggs are from hens raised without the limit of a cage, though they may or may not have spent much time outdoors. Organic eggs are from hens whose food must meet organic standards. These hens must be raised humanly, and they must be given time to the outdoors. Hey, happier hens do lay tastier eggs.
Does local make a difference? Nothing is better than local eggs. They may have a feather or two stuck to them or be a little imperfect in shape and may or may not be certified organic; however, they have one quality. I know exactly where my food came from and how it came into being! In some cases I can even ask the farmer when the eggs were laid and what they were fed.
55.What’s the best title for this passage?
A．Which Eggs Should You Be Eating? B．Eggs Are Changing as Times Are Changing
C．Which Kind of Egg Is the Best? D. The First Concern When Choosing Eggs
56. What does the author think of extra Omega-3s eggs?
A．They are a good choice for people to buy.
B．They contain fewer Omega-3s than fresh fish.
C．They have the highest content of pure Omega-3s.
D．They are not the best source of Omega-3s.
57. The underlined word “free-range” probably means “________ ”
A．wild B．cage-free C．organic D．Omega-3-free
58.According to the passage, which of the following has nothing to do with an egg’s quality?
A．The egg’s color. B．The hen’s exercise.
C．The hen’s living conditions. D．The hen’s food.

American researchers say drinking tea may help strengthen the body’s defense system against infection（感染）．Doctors at Brigham and Women’s Hospital in Boston，Massachusetts，did the study．The team studied a chemical found in black，green，oolong and pekoe tea This chemical is an amino acid（氨基酸）called L-theanine．The scientists say it may increase the strength of Gamma delta T cells，which are part of the body’s defenses．
First，the researchers mixed some of these cells with antigens（抗原）found in the amino acid Antigens help the body react to infection．Then the scientists added some bacteria（细菌）．
Within twenty-four hours，the cells produced a lot of interferon，a substance that fights infection Cells not mixed with the antigens did not produce interferon．
In the second part of the study，eleven people drank five to six cups of black tea every day．Ten other people drank the same amount of instant coffee．That is dried coffee mixed with hot water．
Two weeks later，and again two weeks after that，the researchers tested the blood of all twenty-one people．They also looked at what happened when they added bacteria to the blood cells．They found that the tea drinkers produced five times more interferon after they started drinking tea The coffee drinkers did not produce interferon．
Doctor Jack Bukowski led the study He says the antigens added to the Gamma delta T cells were responsible for the increased reaction to the bacteria．He says the study also showed that the cells were able to remember the bacteria and fight them again the next time．
Earlier research already has found that tea can help prevent heart disease and cancer Doctor Bukowski says the new study must be repeated with more people．If the findings prove to be true，he says，then tea drinking might also help protect against bacterial infections．He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the body’s defenses．
73．We may know from the text that can be found in different kinds of tea．
A．Gamma delta T cells B．L-theanine
C．interferon D．bacteria
74．Tea may help strengthen the body’s defense system because it helps ．
A．the body to produce more interferon
B．the body to produce more Gamma delta T cells
C．to add some bacteria to the blood cells
D．to mix antigens with some of the cells in the body
75．According to Dr Bukowski， ．
A．the findings of the study have already proved to be true
B．he bas taken some amino acid L-theanine from tea and made a drug with it
C．further study is needed to prove the findings true
D．he is not sure whether tea can help prevent heart disease and cancer

Colleges are starting to wake up to how sleep deprivation(剥夺) cuts into the academic and athletic performance of their students. All-nighters have become a habit in higher education, but a handful of small new studies help document the consequences.
A study at St. Lawrence University in Canton, N. Y., showed what may seem obvious to most: All-nighters are not an effective way to succeed in school
"You can't do your best work when you’re sleep-deprived," says psychology professor Pamela Thacher, who wrote the study. Thacher studied the sleeping patterns and grades of 111 students to see the relationship between sleep and their GPAs.
Two-thirds of the students reported that they had pulled at least one all-nighter during a semester. Many students believe that it's a "rite of passage" (标志) to stay up all night during college and that "ifs kind of fun," Thacher says.
But "if you use all-nighters, your GPA is slightly lower on average," Thacher says. "Pulling all-nighters gives in your (overall) sleep" and makes it difficult to reach full academic potential.
Short-term side effects of sleep deprivation include delayed reactions and tendencies to make mistakes.
A Stanford University study may help persuade at least student athletes to make more time for bed. Cheri Mah, a graduate researcher at Stanford, worked with six bas ketball players, who all ran faster and made more shots over a period in which they slept at least 10 hours a night.
"Athletes who get an extra amount of sleep are more likely to improve their performance in a game," says Mah, who released results from an ongoing study in June. "It's not common knowledge, because if people understood how much of a difference (getting more sleep) could make athletically," they'd apply it more to their lives and not focus solely on nutrition and exercise.
1. According to the study at St. Lawrence University,
A. one can reach his potential by staying up late
B. it takes one all night to recite a passage
C. the less one sleeps, the more effective his work is
D. all-nighters affect one's academic performance
2. The underlined word "document" in the first paragraph probably means_ _.
A. prove B. check C. oppose D. improve
3. Which of the following statements is true?
A. All-nighters are a short-cut to success in school
B. All-nighters can make one’s GPAs much higher.
C. Staying up late tends to react slowly and make mistakes.
D. The study may help persuade all students to sleep wall.
4. According to Cheri Mah, .
A. athletes improve their performance only by means of nutrition and exercise
B. it is known to all that those who get extra sleep perform better
C. people don't understand getting more sleep can make a difference
D. athletes should sleep as much as possible to run faster
5. What is this passage mainly concerned about?
A. A study on all-nighters at St. Lawrence University.
B. Collage students’ performance suffering from lack of sleep.
C Short-term side effects of sleep deprivation.
D. A Stanford University study on athletes’ sleep.
