Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good.
1.In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.
“It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? “ 2.“ says Johnson.
Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. 3.
So what is the solution? It’s obvious that we need to eat less sugar. 4.From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat.
But there are those who are fighting back against sugar. 5.Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.
A.We take in more energy and fat.
B.Then the good feeling goes away, leaving us wanting more.
C.Our ancestors were used to poor food, clothing and shelter.
D.So the very thing that once saved us, may now be killing us.
E.Sugar, we believe, is one of the reasons, if not the major one.
F.The trouble is, in today's world, it's extremely difficult to avoid.
G.Many schools are replacing sugary desserts with healthier options like fruit.

Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
Sounds is measured in units called decibels (分贝). At a level of 140 decibels people feel pain in their ears.
Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that has already faced enough stress.
1.The sense of sound _________.
A. makes us feel excited
B. helps us hear more clearly
C. is something harmful to us
D. helps to know what is happening around us
2.When sound is turned into noise, ______________.
A. people grow worse and worse
B. it makes us forget all the past
C. people don’t know what to do with everyday life
D. it will be a kind of pollution to people
3.Why does the passage say peace and quiet are becoming harder to find?
A. Because the world is making more and more noise.
B. Because wars and battles happen here and there in the world.
C. Because all the sounds are becoming over 140 decibels.
D. Because some machines can make noise.
4.Doctors say we can hear ourselves think __________.
A. if we don’t like to hear noise
B. if we have no aches or pains in our bodies
C. if there isn’t too much noise
D. if we can’t be careful of noise

Many people drink coffee to quickly increase their energy. Scientists say there may be another reason to drink coffee. They studied the link（联系）between coffee drinking and the risk of death from some diseases, and found that drinking moderate（适量的）amounts of coffee each day may help protect against heart disease, cancer and other diseases. David Jacobs of the University of Minnesota in Minneapolis worked on the study with researchers from the University of Oslo.
The researchers used information about 27,300 women. They were between 55 and 69 years of age when they entered the study. During a fifteen-year period, almost 15.75% of them died. The researchers found a link between the amount of coffee the women reported drinking and their risk of dying from heart disease. Coffee drinking was measured in cups. One cup is about 225 grams.
There was a reduced risk of death from heart disease among women who drank from one to three cups of coffee each day. A reduction（减少）in the risk of death from other diseases was also seen. But Professor Jacobs says the risk reduction for death from heart disease decreased in women who drank more than three cups a day.
The researchers say antioxidants（抗氧化剂）in coffee might reduce the risk of heart disease. Earlier studies found that coffee has high levels of antioxidants. Antioxidants have been shown to help prevent heart disease, cancer and other diseases.
1.How many women are alive after the study of fifteen years?
A. About 23,000. B. About 4,300. C. About 42,000. D. About 1,400.
2.What does the underlined word “decreased” in paragraph 3 mean?
A. Rose. B. Reduced. C. Improved. D. Continued.
3.It can be inferred that Professor Jacobs suggests we drink ________each day.
A. more than three cups of coffee B. one to three cups of coffee
C. about 225 grams of coffee D. as much coffee as possible
4.The last paragraph mainly explains why ________.
A. many people like drinking coffee
B. some people die from heart disease
C. coffee helps prevent heart disease
D. coffee has high levels of antioxidants

Kids are natural scientists. That may be why they ask so many questions.
Younger kids take up science and math with amazing enthusiasm，yet as they get older they often lose their excitement. Children look on scientific exploration as play，but as they get older they start to connect it with big heavy books，long worksheets and a lot of really confusing words.
What a tragedy！We had their attention，they were listening，they were participating，they were learning and then we lost it to boredom.
We need our kids to play more. More play brings up basic scientific concepts(概念)．Being familiar with basic scientific concepts brings about exploration which leads to research. Once they are researching，they are completely into the learning.
My boys built a small 9hole golf course next to our driveway one day. It was a great product of science. They dug out the holes and channels to guide the golf ball. They played with architecture(建筑学)with a series of pipes they had found in the garage. They tested speed and momentum(动量)by creating one of the holes across the driveway. They experienced biology when deciding which front yard plants could be used as a part of the course and which needed to be pulled up.
If I had sent them out to the yard to build a 9hole golf course，it would have never happened. It was because it was their idea that it worked. I try to tell them some of the concepts after the fact. When they ask about something，I try to relate it back to something they have built，experienced，or felt. I try to give them a vocabulary around what they already know.
An afternoon can change the way kids look at the world. Not bad for a day of play.
1.What can we learn about kids' attitudes towards science from the first three paragraphs?
A. Kids think they are born to work as scientists.
B. Younger kids begin to learn science on purpose.
C. Older kids often link science with boring things.
D. Children's taking an interest in science is a tragedy.
2.By building the small golf course，the writer's boys learnt about all of the following things EXCEPT________.
A. speed B. momentum
C. biology D. agriculture
3.If the writer had forced the boys to build a small golf course，they might have _______.
A. asked her some related scientific concepts
B. made a better golf course than the one they had built
C. asked their friends to help them with the work
D. got bored and refused to follow the writer's directions
4.In which part of a newspaper is the article probably included?
A. Architecture. B. Education.
C. Health. D. Sports.

Despite what so many people would love to believe，NASA hasn’t discovered any evidence of past or present intelligent life on Mars. Therefore, when the Curiosity rover (好奇号探测器)found something suspicious on the Red Planet’s surface, they were not only surprised but also a little bit worried.
The thin fragment (碎片)was suspicious enough to guarantee its own name, with NASA’s Curiosity rover team calling it the “Pettegrove Point Foreign Object Debris，” named for where it was discovered. With no idea what it was or where it came from, the rover’s handlers began to worry that it might actually be a piece of the rover itself，suggesting some unseen damage or other issue with the robot. Thankfully，those concerns seem to have been unfound.
In a new update from NASA the object has now been identified as a natural piece of rock rather than a piece of any man-made craft or vehicle. The team analyzed the unusual object with a tool called the Chem Cam RMI. The instrument uses a laser (激光器)to sniff out the makeup of anything that is pointed at, and the results for this particular piece of debris revealed that it’s actually just a very thin piece of rock.
NASA describes the inspection: The planning day began with an interesting result from the previous plan’s Chem Cam RMI analysis of a target that was referred to as “Pettegrove Point Foreign Object Debris”(PPFOD)，and supposed to be a piece of spacecraft debris fact. In fact it was found to be a very thin slice of rock, so we can all rest easy tonight. Curiosity has not begun to shed its skin!
How this particularly thin sliver of rock got to where it is—and why it seems to be a different colour than the surrounding sand and debris—remains unexplained, but at least the rover isn’t falling apart.
1.What attitude did NASA hold towards the newly found thin fragment?
A. Positive and excited. B. Surprised and delighted. C. Interested and doubtful. D. Amazed and worried.
2.What is the “Pettegrove Point Foreign Object Debris” named for?
A. Its finder. B. Its location. C. Its researcher. D. Its shape.
3.According to the passage, which of the following is right?
A. Most people believe there isn’t any intelligent life on Mars.
B. The recent concerns connected with the thin fragment have not been discovered.
C. According to NASA, the object found recently was a piece of man-made craft or vehicle.
D. The object once making many people worried has the same colour with the surrounding sand.
4.In which part of newspaper can you read the text?
A. Travelling. B. Sports. C. Science. D. Food.

As a Chinese saying goes, “Taste is actually a memory of childhood”. Local specialty food may not be popular among all people, but it offers outsiders a glimpse of local culture and history.
Gongcheng “oil tea” is such a kind of food that would be considered “weird” by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region. Many people dislike its bitter and astringent（涩的）flavor when they take a sip.
“It felt like drinking Chinese herbal medicine. I never expected that I would gradually accept it afterwards, and even become addicted to it,” said a traveler surnamed Zhang who comes from Shijiazhuang in northern China’s Hebei province.
Langshan village is said to be birthplace of Gongcheng “oil tea” whose ideal ingredients are green tea and fermented（发酵）tea. The village has preserved well its buildings and roads dating back to late Qing Dynasty (1644-1911), as well as its traditional way of making the special tea.
Lin Fengyou, 60, introduced the cooking process. She looks younger than her age, and attributes this to the benefits of drinking “oil tea” throughout the year.
The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot, and then add edible（可食用的）oil and boiled water afterwards. She filters off the solid residues（余渣）, and pours the glue-like green tea soup into bowls. Then, she adds salt, caraway seed（葛缕子籽）, green onion, dried rice, fried groundnuts, sliced taro（芋头）and fried beans.
The taste of the “oil tea” is a mixture of the distinctive（特有的）flavors of all its ingredients. Local people usually eat it together with glutinous rice（糯米）balls, rice dumplings and glutinous rice cake.
The villagers consume “oil tea” three times a day. The tea soup is a healthy and refreshing food. “The tea soup to us is coffee to Westerners”, said Lin. “But it is tastier.”
1.Many first-time visitors may find “oil tea” ________ when taking a sip.
A. popular B. beneficial
C. addicted D. strange
2.What can we learn about Lin Fengyou according to the passage?
A. She thinks drinking “oil tea” throughout the year makes her look younger.
B. She is one of the reasons why the special tea has been preserved.
C. She never expected that she would gradually accept “oil tea”.
D. She drinks “oil tea” three times every day and considers coffee tastier.
3.Which is the correct order of cooking “oil tea” according to Lin Fengyou?
a. pour the glue-like green tea soup into bowls
b. heat the tea in an iron pot and pound the tea
c. add salt, caraway seed, green onion, dried rice, etc
d. add edible oil and boiled water
e. filter off the solid residues
A. acebd B. dbace
C. bdeac D. beadc

"Beating is a sign of affection, cursing (骂）is a sign of love."
Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been—but experts say they still ring true.
Today, it seems, Chinese parents are more likely to send their children to pre-college military academies in the United States in the hope that some tough love will pave the way tosuccess.
"Good education doesn't mean letting your child enjoy privileges, especially our boys," said Song Wenming, an entrepreneur(企业家）in Jinhua, East China's Zhejiang province." They should be raised in tough conditions to know what to fight for in the future."
In August, Song sent his 17-year-old son to Valley Forge Military Academy (VFMA) in Pennsylvania. And he is far from alone, even though it takes a lot of money - around $48,000 per year —to send a child to a strict military school.
Statistics shows that an increasing number of Chinese students have been registering with such academies.
A few years ago, there were no Chinese students at Valley Forge. Today, there are 28."All of the Chinese students at Valley Forge came from wealthy families, some of them were spoiled," said Jennifer Myers, director of marketing and communications at the school.
Song's only son, Song Siyu, had a rocky start during his first six weeks at the school. The teenager said he went to the school voluntarily but did not expect it to be as difficult.
Now, three months later, he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision. He can even take criticism, no matter how unreasonable.
"The training is hard but I know it is good for self-development of individuals," said Song Siyu.'The endless training and scolding are just ways to build up our character, they are not personal."
But his enthusiasm is not universal. Ten of the 13 Chinese students who joined the academy this year have transferred to other schools.
But for those who stick with it, there is a reward for all the hard work.
1.From the second paragraph, we can know the old Chinese saying _____.
A．is out of date in modern times.
B．is disagreed by rich parents.
C．is still worth trusting.
D．is deeply believed by better educated parent.
2.The underlined sentence means that _____
A．Song sent his only son to military school, so he feels lonely.
B．Song is the only one who sends his child t to military school.
C．There are other people sending their children to military school besides Song.
D．The fee of the military school is so high that only Song can afford it.
3.Song Siyu got some achievements in the military school except _____.
A．taking a bath in a short time B．having his meal with his eyes closed
C．taking unreasonable criticism D．improving his character
4.How many Chinese students are there at Valley Forge before this year?
A．10 B．13 C．15 D．25
5.Which of the following can be inferred from the passage?
A. It's likely that more and more Chinese students will attend VFMA.
B. Most Chinese parents approve of educating their children by beating and cursing nowadays.
C. Song Siyu had no difficulty in adjusting to the life at VFMA.
D. Most Chinese students support the way of education at VFMA.
