Anxiety has now surpassed depression as the most common mental health disease among college students, though depression, too, is on the rise. More than half of students visiting campus clinics cite anxiety as a health concern, according to a recent study of more than 100,000 students nationwide by the Center for Collegiate Mental Health at Penn State. Nearly one in six college students has been diagnosed with or treated for anxiety within the last 12 months, according to the annual national survey by the American College Health Association.

The causes range widely, experts say, from mounting academic pressure at earlier ages to overprotective parents to engagement with social media. Anxiety has always played a role in the development of a student’s life, but now more students experience anxiety so acute that they are seeking professional help. Like many college clinics, the Center for Counseling and Psychological Services at the University of Central Florida (UCF)— one of the country’s largest and fastest-growing universities, has seen sharp increases in the number of clients: 15.2 percent over last year alone.

Anxiety has become characteristic of the current generation of college students, said Dan Jones, the director of Counseling and Psychological Services at Appalachian State University in Boone, N. C. Because of increasingly pressures during high school, he and other experts say, students arrive at college preloaded with stress. Accustomed to extreme parental oversight, many seem unable to govern themselves. And with parents so accessible, students have had less incentive to develop life skills. “They can’t tolerate discomfort or having to struggle,” Dr Jones said.

More often, anxiety is mild and temporary, the indication of a student under the control of a normal developmental issue-learning time management, for example, or how to handle rejection from a sorority. Mild anxiety is often treatable with early, modest interventions. But to care for rising numbers of severely troubled students, many counseling centers have moved to triage protocols (分诊措施). That means that students with less urgent needs may wait several weeks for first appointments.

Like many college counseling centers, UCF has designed a variety of daily workshops and therapy groups that implicitly and explicitly address anxiety, depression and their triggers. Next fall the center will test a new app for treating anxiety with a seven-module cognitive behavioral program, accessible through a student’s phone and augmented with brief videoconferences with a therapist. It also offers semester-long, 90-minute weekly therapy groups, such as “Keeping Calm and in Control”, “Mindfulness for Depression” and “Building Social Confidence” -for students struggling with social anxiety.

1.Which of the following contributes to anxiety according to the text?

A. Protection from teachers.　　 B. An app in students’ phones.

C. Increasingly learning pressure.　　 D. Management of time learning.

2.What does the underlined word “incentive” in Paragraph 3 probably mean?

A. Prevention.　　 B. Motivation.　　 C. Acquisition.　　 D. Direction.

3.What’s the purpose of those therapy groups mentioned in the last paragraph?

A. To help students suffering anxiety.

B. To test what social anxiety is.

C. To introduce the cognitive behavioral program of UCF.

D. To emphasize the importance of calm and confidence.

4.Which of the following would be the best title for the text?

A. Tips on dealing with anxiety

B. Causes of anxiety and depression

C. Different mental diseases threaten college students

D. College mental health centers overburdened with anxious students

People often talk as if shyness is a disease or mental condition that can be cured. I prefer to think of it as an emotional disability. It’s something we are born with and something we carry with us in our entire lives. There are too many people, however, who seem to be determined to find some way of doing away with their shyness. In my opinion, it’s a waste of time. I don’t mean that we should do nothing about it; quite the contrary, I think we need to separate the basic fact of our shyness from our ability to take part in a social environment.

Look at one of the most famous shy people of them all, Johnny Carson. This man is painfully shy, yet for decades he made a living talking and associating with different people every night, in front of a national audience. Carson has never done away with his shyness, but he has successfully found a way to deal with it to the extent that he could be, not just a talk show host, but a legend among talk show hosts. Look also at Sally Fields, who has recently admitted her problem with shyness. This is a woman who has appeared in many films, TV shows and interviews, yet in her early years she was so shy that she turned down a lunch invitation from Jane Fonda because she was terribly afraid of meeting her.

I guess that our shyness is there because each of us is born with some insecurity and this insecurity prevents us from reaching out to others the way people with a more open personality do. As we grow up and become adults, we allow our social skills to grow and develop. But we are still stuck in kindergarten or elementary school or wherever it was when our shyness took root in our soul.

1.In the author’s view, shyness can be explained as　　.

A. a not very normal mental condition

B. a disease that can be easily cured

C. something we pick up after birth

D. a kind of emotional disability

2.From the passage, we know that Johnny Carson　　.

A. has dealt with shyness very successfully

B. has done away with his shyness carefully

C. is described as a hero in some legend books

D. failed to become a good talk show host

3. The passage tells us that Sally Fields was　　.

A. proud all the time

B. close to Jane Fonda

C. impolite when young

D. shy in her early years

4.The author thinks that our shyness is there because　　.

A. we are not open enough

B. we don’t feel secure at heart

C. we try to reach out to others all the time

D. we lack some social skills

Late blight (晚疫病) is a common disease of plants such as tomatoes and potatoes, capable of wiping out entire crops on commercial-sized fields. If conditions are favorable, it can quickly spread to other plants through wet soil and wind.

In history, late blight caused over 1 million deaths in Ireland. Today it still causes more than 6.7 billion dollars in annual losses worldwide. Small farms and growers are often the hardest hit, many stating losing almost two-thirds of their yearly production, because usually they don’t have money to identify and treat the disease.

But farmers may have a new weapon now. The technology, designed by researchers at North Carolina State University can recognize sick plants early by employing a piece of test paper that plugs into (接入) a reader on a smartphone.

Plants produce signaling chemicals from their leaves. “If a plant is diseased, the type and concentration of these chemicals changes,” said Wei Qingshan, an engineer at North Carolina State University. If the farmer suspects a late blight infection is underway, he can remove a leaf from a living plant and place it in a small, covered glass jar. After the leaf’s volatile (挥发性的) chemicals have accumulated for 15 minutes or so, the cap is removed and the air is pumped from the jar into a reader attached to the back of a smartphone. Inside the smartphone reader is a piece of paper specially treated with dyes (染料) by the researchers. Upon interacting (相互作用) with the plant’s volatile chemicals, the paper changes color to indicate the presence or absence of the late blight.

The researchers hope to tailor the technology for other crop diseases, which continue to appear as climate change and global trade increase the stress on agricultural systems. “This is an important step in the improvement of global food security,” Wei Qingshan said.

1.What are the statistics in Paragraph 2 mainly about?

A.The damage caused by late blight.

B.The money put into late blight treatment.

C.The number of crops in a commercial-sized field.

D.The yearly production of small farms and growers.

2.According to Wei Qingshan, how would a farmer find out if a plant was infected?

A.By treating the plant with special dyes.

B.By putting volatile chemicals on the plant.

C.By testing the air in the jar with a leaf inside.

D.By examining the land with a smartphone reader.

3.What do the researchers expect of their new technology?

A.It’ll reach farmers soon.

B.It’ll get rid of late blight.

C.It’ll be beneficial to the climate.

D.It’ll be able to detect more crop diseases.

4.What is the purpose of this passage?

A.To introduce a test method of late blight.

B.To explain the causes of late blight.

C.To discuss the effects of late blight.

D.To tell the history of late blight.

Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.

Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.

For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
