We know that hugs make us feel cosy inside. And this feeling could actually ward off stress and protect the immune (免疫) system, according to a new research from Carnegie Mellon University.

It’s a well-known fact that stress can weaken the immune system. In this study, the researchers sought to determine whether hugs could protect individuals from the increased sensitivity to illness brought on by the particular stress that comes with interpersonal conflict.

“We know that people experiencing ongoing conflicts with others are less able to fight off cold viruses. We also know that people who report having social support are partly protected from the effects of stress on psychological states, such as depression and anxiety, ” the study’s lead author, psychologist Dr. Sheldon Cohen , said in a statement. “We have tested whether awareness of social support is equally effective in protecting us from sensitivity to infection caused by stress and also whether receiving hugs might partially account for those feelings of support and thus protect a person against infection.”

In the experiment, over 400 healthy adults filled out a questionnaire about their perceived (感知到的) social support and also participated in a nightly phone interview for two weeks. They were asked about the frequency that they engaged in interpersonal conflict and received hugs that day.

Then, the researchers exposed the participants to a common cold virus, and monitored them to assess signs of infection. They found that both perceived social support and more frequent hugs reduced the risk of infection associated with experiencing interpersonal conflict. Regardless of whether or not they experienced social conflicts, infected participants with greater perceived social support and more frequent hugs had less severe illness symptoms.

“This suggests that being hugged by a trusted person may act as an effective means of conveying support and that increasing the frequency of hugs might be an effective means of reducing the effects of stress,” Cohen said. “The apparent protective effect of hugs may result from the physical contact itself or hugging being a behavioral indicator of support and closeness. Either way, those who receive more hugs are somewhat more protected from infection.”

If you need any more reason to wrap your arms around someone special, consider this: hugs also lower blood pressure, reduce fears, improve heart health and decrease feelings of loneliness.

Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

What to Expect

The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

Accommodation Zones

Homestays are located in London mainly in Zones 2, 3 and 4 of the transport system. Most hosts do not live in the town centre as much of central London is commercial and not residential(居住的). Zones 3 and 4 often offer larger accommodation in a less crowded area. It is very convenient to travel in London by Underground.

Meal Plans Available

◇ Continental Breakfast

◇ Breakfast and Dinner

◇ Breakfast, Packed Lunch and Dinner

It's important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal, bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinners usually consist of meat or fish with vegetables followed by dessert, fruit and coffee.

Friends

If you wish to invite a friend over to visit, you must first ask your host's permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.

Self-Catering (自助的)Accommodation in Private Homes

Accommodation on a room only basis includes shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practice English at home quite as much.

According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end re­sult is that the opposite sides of the body are controlled by the opposite sides of the brain.

The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in read­ing, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.

Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.

There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instru­ments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.

1.Which of the following statements is TRUE according to the passage?

A. Left-handed people are better at speaking

B. Left-handed people are believed to have stronger left halves of the brains

C. Right-handed people are cleverer than left-handed people

D. Right-handed people work best with the right side of their bodies

2.Which of the words or phrases is closest in meaning to the word “asymmetrical”?

A. valuable B. not typical

C. not balanced D. negative

3.What can be inferred from the passage?

A. Left-handed people may feel inconvenient in this right-handed society

B. This is an equal society for the left-handed people

C. Most great geniuses are left-handed

D. Left-handed people are considered to be disabled

4. What’s the best title for the passage?

A. Which proves to be the better way to live, right-handed or left-handed?

B. How do left-handed people differ from right-handed ones?

C. Why are some people left-handed?

D. Are left-handed people equally treated in society?

Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone makers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters.

If health issues arise from cell phone use, the possible effects are huge. According to Devra Davis, an expert who has worked for the University of Pittsburgh, brain cancer is a concern. Over all, there has not been an increase in its occurrence since cell phones arrived. But the average masks an increase in brain cancer in the 20-29 age group and a drop for the older population.

“Most cancers have many causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.

Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates (穿透) only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls (头骨) are thinner and their brains contain more absorptive fluid.

Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.

Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the belly.

1.According to Ms Davis, brain cancer increases ________.

A. in the teenagers B. among old people

C. in the twenties D. among pregnant women

C. passive D. sensitive

3. The author’s purpose of writing the text is most likely to ________.

A. entertain B. persuade

C. describe D. inform

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

A. Low-energy Radiation Leads to Cancer

B. Cell Phone Use Brings Health Problems

C. Radiation Damages DNA in People’s Brain

D. Researchers Launched Lab Studies on Cell Phones
