A new study by a Penn State College of Medicine research team found that honey is a better and safer treatment for children than cough medicines.
Ian Paul, the study’s lead researcher, was motivated to test honey because treating coughs in children has recently become a sticky subject. Coughing is the body’s way of clearing irritated (受刺激的) airways to help you breathe. But too much coughing can irritate your lungs and throat even more. It can also make it tough to get the sleep your body needs to heal. Hoping to ease the suffering of their children, parents often give them cough medicines.
But there have never been any good studies showing that they work. Cough and cold medicines may also cause serious side effects. Hundreds of kids die in the hospital each year after receiving too much cough medicine by mistake. Last October, the US Food and Drug Administration suggested that parents should not give cough medicines to children under 6.
In order to search for a different solution, Paul designed a study that involved 105 kids who were sick with coughs and other cold conditions. At bedtime, the kids took buckwheat (荞麦) honey, honey-flavored (蜂蜜味的) DM (one of the most common ingredients in cough medicines), or no treatment. Parents and kids in the no-
-treatment group knew they weren’t getting anything, but the other two groups weren’t told which treatment they were getting.
The surveys showed that kids who swallowed about 2 teaspoons of buckwheat honey before bedtime coughed less and slept better than kids in the other groups. “When parents want something for their kids to take,” Paul says, “honey seems like the best option”.
But what gives honey its healing power? Substances called antioxidants (抗氧化剂) may be part of the answer. All honey contains antioxidants that protect our cells from damage. Studies show that antioxidant levels in the body rise after someone swallows honey.
68. Which of the following can be the best title for this passage?
A. No cough medicines to children
B. Sweet solution to kids’ coughing
C. Best treatment for your cold
D. Cough medicines don’t work
69. We can learn from Paragraph 2 that coughing ______.
A. sometimes does good to people
B. can cure lung and throat diseases
C. is more harmful to children
D. helps improve children’s diet
70. During Paul’s experiment, the kids who received treatment ______.
A. seemed much worse than before
B. knew they weren’t getting anything
C. coughed less and slept better
D. had no idea what they swallowed

A nice warm cup of tea a day might keep glaucoma (青光眼) at bay,according to new research published in the British Journal of Ophthalmology.
Risk of developing glaucoma — one of the leading causes of blindness around the world that currently affects nearly 58 million people — might be lowered by drinking hot tea daily. The disease causes fluid to build up inside the eye that puts pressure onto the optic nerve (视神经). Previous research said that caffeine (咖啡因) might prevent this build-up but the new findings showed that drinking decaffeinated and caffeinated coffee, iced caffeinated tea and caffeinated sodas had no effect on glaucoma risk.
In the new study, researchers looked at the National Health and Nutrition Examination Survey for the 2005 — 2006 year of 10,000 adults and children. The data is from interviews with the patients, their physical exams and blood tests. That specific year also included eye tests for glaucoma in 1678 adults and showed that about 5% had the disease. Those patients were asked how many caffeinated and decaffeinated drinks they consumed during that year and how often. The results of the questionnaire showed that those who drank hot tea daily were 74% less likely to develop glaucoma than their peers who didn’t.
“Tea has long been recognized to have various chemicals that contribute to lowering the risk of heart disease, cancer and diabetes,” the researchers said. But further study is needed to determine if things like the size of the cup,type of tea and length of brew (冲泡) time influence the results.
1.What can we learn about glaucoma?
A. It can be cured by drinking hot tea daily.
B. It is a great threat to people’s eyesight.
C. It affects nearly 58 million people yearly.
D. It is caused by too much pressure on the eyes.
2.What did previous research find?
A. Drinking coffee reduces glaucoma risk.
B. Iced tea has no effect on glaucoma risk.
C. Caffeine does good to glaucoma patients.
D. Caffeine causes fluid to build up in the eyes.
3.How was the new study carried out?
A. By interviewing patients.
B. By testing participants’ eyes.
C. By handing out questionnaires.
D. By studying data from previous studies.
4.What does the underlined phrase “those patients” in Paragraph 3 refer to?
A. The 10,000 adults. B. The 1,678 adults.
C. The 5% adults. D. The 74% adults.

A new study has found some secrets of people’s understanding of large numbers.
Researchers studied a group of people who were born deaf and never learned any spoken language or a formal sign language, but they have developed a gesture system to communicate with people around them. The gestures let them express approximate amounts, but not exact numbers.
“Up to three, they’re fine,” says Elizabet Spaepen, a researcher at the University of Chicago and an author of the study. “But past three, they start to fall apart.” In one test, Spaepen would knock her fist against a study participant’s fist a certain number of times and then ask them to respond with the same number of knocks. “If I were to knock four times on their fist, they might knock on my fist five times,” she says.
The finding offers a clue to just how much language affects our understanding of numbers. That has been a big question since 2004, when other researchers published data on two tribes in the Amazon whose members also lack words for big numbers. “What they have are words that mean one and two,” Spaepen says, “and then they have a word to mean many.”
Members of the Amazonian tribes also had trouble matching numbers larger than three or four. But some scholars felt that these earlier studies failed to prove that language was the reason. They pointed out that the tribes lived in groups that didn’t use money and had no need for exact numbers.
The new research appears to answer that criticism. “It proves that the kinds of problems in understanding numbers that we found in the Amazonian tribes are not due to just the cultural or environmental circumstances,” says Peter Gordon of Columbia University, one of the researchers involved in the earlier studies.
1.The participants of the new study ______.
A. cannot communicate with one another
B. use a formal sign language to express numbers
C. have some physical disability
D. come from a distant tribe
2. According to the passage, the new study _______.
A. ignored the cultural influence on the participants
B. is doubted by many people
C. has found it is harder to learn numbers than learning a sign language
D. has shown that our understanding of numbers is influenced by our mastering of language.
3. The tribes involved in earlier studies _________.
A. often dealt with big numbers.
B. didn’t use money in their daily life
C. didn’t have their own language
D. often made trouble for the researchers
4. What can we learn from the last paragraph?
A. Peter Gordon is a researcher of the University of Chicago.
B. Peter Gordon thinks less of the new study than his earlier studies.
C. Peter Gordon believes people’s understanding of numbers has nothing to do with cultural circumstances.
D. Peter Gordon is in favor of the finding of the new study.
5.In which part of a newspaper would you most probably find this passage?

A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.
Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived(感知到的)social isolation than those who said they spent a half-hour per day or less on the same sites.
According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader’s Digest. “Although people think being on social media all the time makes them ‘connected’ to others, they are actually ‘disconnected,’ because the more time one spends behind a screen, the less time one spend face-to-face.”
“Part of the issue of loneliness is that the majority of people who use social media aren’t just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else’s posts, where they are and what they are doing. The constant exposure to everyone else’s ‘perfect’ life experiences causes feelings of being left out.”
So what’s the answer? It’s simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else’s life. Just focus on your own life, where you’re going, what you are grateful for, and what you want to accomplish in this world.”
1.What is the finding of the new study?
A. Humans are social-emotional beings.
B. Social media platforms are overused by the young.
C. Social media strengthens interpersonal relationship.
D. Heavy use of Social media can lead to loneliness.
2.How did the team conduct their research?
A. By asking questions. B. By experimenting.
C. By distributing forms. D. By media reporting.
3.Who might have a strong feeling of social isolation?
A. Those who use a single social media platforms.
B. Those who spend three hours a day on social media.
C. Those who don’t spend time on social media.
D. Those spending a half-hour per day on social media.
4.What does Kersting suggest people do to avoid feelings of social isolation?
A. Never compare with others. B. Make more fiends on the internet.
C. Choose a travel destination. D. Set up a clear goal for the future.

A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.
The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.
They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.
Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.
“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.
1.Why do yellow taxis result in fewer accidents?
A. Because yellow signals a warning of danger.
B. Because yellow can be seen more easily.
C. Because drivers tend to he more careful in yellow taxis.
D. Because people act more quickly in yellow surroundings.
2.What’ s Prof Ho’s study based on?
A. Physical risks taxi passengers experience.
B. The economic effect of changing taxi color.
C. Personal reports from taxi drivers worldwide.
D. Data from Singapore's largest taxi company.
3.What do Prof Ho’s words in the last paragraph suggest?
A. School buses should be painted yellow.
B. Their findings are worth popularizing.
C. Their study will be furthered.
D. Yellow should be widely used in public transport,
4.What can be the best title for the text?
A. Safer to ride in yellow taxis B. Caution: yellow taxis ahead
C. Why are yellow Taxis preferred? D. How can colors help prevent accidents?

Whale researchers believe they have found a new way to measure the amount of stress felt by whales when they experience serious threats, such as being hit by a ship, and they say the technique could help protect the huge sea creatures from dying off.
American Rosalind Rolland is the lead scientist on the project. She and her team are with the New England Aquarium in Boston, Massachusetts. They measured stress hormones (荷尔蒙 ) by studying baleen, a substance found in the upper part of the mouth of some kinds of whale. She explains that the baleen serves as a record that shows a spike in stress hormones when whales face dangers such as a changing climate and ship strikes. Scientists can then read these records, similar to reading the rings on a tree.
Understanding the information is important because whales who often feel stressed are less likely to be reproductive and more likely to become sick. That combination is not good for the whale population, which is already dangerously low.
The scientists did their work on a whale that had become trapped in fishing equipment, which some scientists estimate kills up to 300, 000 whales and dolphins annually. It was finally killed by Inuit hunters who found it trying to drag the fishing equipment. The hunters said the whale seemed to lack energy. When scientists examined the dead whale, they found its mouth showed an increase in stress hormones 20 times greater than normal.
Regina Asmutis-Silvia is a biologist with the Whale and Dolphin Conservation in Massachusetts. She didn’t participate in the research, but she says it is important. “We clearly understand that stress is bad for humans. We also need to understand that stress is bad for other animals, too,” she adds.
1.What does the text mainly tell us?
A.The dangers the whale often faces.
B.The measures to stop sea life being hit.
C.A discovery to measure stress on whales.
D.A way to protect the mouth of the whale.
2.Which of the following can best replace “spike” underlined in Paragraph 2?
A.Rise. B.Change. C.Crash. D.Slide.
3.What may a whale living a stressful life be like?
A.Calm and fierce. B.Unhealthy and unable to reproduce.
C.Uneasy and energetic. D.Sizeable and likely to lose appetite.
4.Why does the author mention the words by Regina?
A.To move on to another topic.
B.To stress the importance of the finding.
C.To tell the necessity of studying other animals.
D.To show the similarity between humans and animals.
