There is an English saying:“{#blank#}1{#/blank#}.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. {#blank#}2{#/blank#}.

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. {#blank#}3{#/blank#}. If laughter exercises the body, it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program. {#blank#}4{#/blank#}.

    {#blank#}5{#/blank#}. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A. Laughter can make one's life longer.

B. As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh.

C. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which reduce both stress and pain.

D. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach and even the feet.

E. Although laughter helps cure the disease, doctors still can not put this theory into clinic practice.

F. Laughter is the best medicine.

G. They have found that laughter really can improve people's health

    Your mobile is now much more than just a communication device - more like a remote control for your life. You still call it a "mobile" from habit, but it is an organizer, entertainment device, payment device and security（安全） center, all developed and manufactured by engineers.

    What we do need is better mobiles and more intelligence. Because it knows your travel timetable it can check for problems on the roads or with the trains, giving you the best route into work. It can control your home, reprogramming the central heating if you need to get up earlier and keeping an eye on your home by connecting your mobile with the home security system. It is your payment system—you can pay for tickets for journeys or buy items in shops by placing the phone near a sensor(感应器). With an understanding of location, the mobile can also provide directions, or even tell you if your friends or family are nearby.

    Usually it will start work even before you wake. It will work with your home entertainment system while you sleep to find programmes that will interest you and download them as a podcast to watch on the train or in other spare moments. It will intelligently work out what to do with incoming phone calls and messages. Because it knows your diary it will also know, for example, to direct voice calls to voicemail when you are in a meeting, perhaps providing a discrete text summary of the caller and the nature of their call.

    With its understanding of almost all aspects of your life; many new services become possible. For example, a “Good Food” meal planning service could send daily suggestions for your evening meal based on learned preferences, previous selections made and the likely contents of your refrigerator.

    Ten years ago the mobile was purely a device for making voice calls. Now it is a camera, MP3 player, and texting device. This is only the start of an evolution that will turn it into our trusted and indispensable companion in life.

    Put a group of strangers in a room together, and they'll probably start a conversation. “Hot today, isn't it?” one might say. “You said it,” another replies.

    Why do we talk so much about the weather? When we meet new people, we don't begin by telling them our life story. We start with small talk, a polite conversation about something like traffic or weather.

    Research suggests that small talk can build new friendships. When we begin conversations with new people, we want to feel comfortable, and so do they. We use small talk to find common interests. Once we have a common interest, a friendship can begin.

    Small talk even helps people get a job. In order to impress at a job interview, you need to bond with the interviewer right away. Proper sma ll talk can make that first impression get you the job.

    So, how can you make small talk lead to a new friendship or job? First off, find common ground. Select something around you that you share with the other person.

    Next, keep the conversation going. Compliment (赞美) the other person to make him or her feel comfortable, and ask questions to show interest.

    Third, keep eye contact. When you loop people in the eye, they feel you appreciate what they are saying. It makes you appear honest and build trust.

Naturally, shy people might not have enough confidence to start up conversations with strangers. Talking to someone you don't know is not the easiest thing to do! Some experts say with more practice, small take does get easier.

    Some people avoid small talk because they dislike discussing things like traffic or weather. For them, they are just too small. However, when you think about it, small talk is anything but small. In fact, it is actually a very big deal!

    With busy lives, it can be hard to find time to volunteer. However, the benefits of volunteering are great to you, your family, and your community(社区).

    One of the better-known benefits of volunteering is the effect on the community. Volunteering allows you to connect with your community and make it a better place. Volunteering also strengthens your ties to the community and broadens your support network, exposing(使暴露) you to people with common interests, neighborhood resources, and fun and satisfactory activities.

    While some people are naturally outgoing, others are shy and have a hard time meeting new people. Volunteering gives you the opportunity to practice and develop your social skills, since you are meeting regularly with a group of people with common interests. Once you have the desire, it's easier to make more friends and contacts.

    Volunteering provides many benefits for both mental and physical health. You're doing good to others and the community, which makes you experience the pleasure of success. Your role as a volunteer can also give you a sense of pride and identity.

    Reducing the risk of depression(沮丧) is another important benefit of volunteering. A key risk factor for depression is social isolation. Volunteering keeps you in regular contact with others and helps you develop a solid support system, which in turn protects you against stress and depression when you're going through challenging times. Volunteering is good for your health whether you are young or old, but it's especially good in older adults.

    Volunteering offers you the chance to try out a new career without making a long-term commitment. It is also a great way to gain experience in a new field. Volunteering work can expose you to professional organizations or internship（实习）that could be of benefit to your career. That volunteer work is unpaid doesn't mean the skills you learn are basic. Many volunteering opportunities provide training. In addition, volunteering can also help you build upon skills you already have and use them to benefit the greater community.

    Volunteering is a fun and easy way to explore your interests and passions. Volunteer opportunities that match both your goals and your interest are most likely to be fun and satisfying for you. Doing volunteer work you find meaningful and interesting can be a relaxing escape from your day-to-day routines of work, school, and family commitments. Volunteering also provides you with renewed creativity, motivation, and vision that can be carried over into your personal and professional life.

How Bad Are Energy Drinks for Children?

    What Are Energy Drinks?

    There is no clear definition of what makes an energy drink, but it is usually taken that anything non alcoholic with more than 150mg of caffeine per litre is an energy drink. The first of its kind was Lucozade, which was launched in 1927. It was promoted as helping the sick to get better by regaining lost energy. Now there are lots of energy drinks on the market, all claiming to help boost energy levels and aid our performance.

    What's in Energy Drinks?

    We've mentioned the caffeine but energy drinks also contain water and sugar. Some also contain alts and amino acids.

    What Are the Health Concerns?

    The concerns focus on the two main ingredients (成分) of energy drinks, caffeine and sugar. Too much caffeine for children can in the short term cause headaches and raise blood pressure although it is important to mention that caffeine may not harm children in the long term. However, the short term issues do really worry teachers as caffeine can lead to an inability to sleep, which then affects a child's ability to focus and concentrate in class. In fact the maximum recommended (推荐) intake of caffeine for children is 2.5mg for every kilogram a child weighs, so if a child drinks energy drinks, it would be very easy to go over this dose.

    Too much sugar can also cause health problems including obesity, tooth decay and in the long run Type 2 diabetes. So as with caffeine, if children are drinking energy drinks and consuming sugar in foods and other drinks, then it would be easy to go over the daily sugar allowance for a child. The thing to be aware of is what is called free sugars. Free sugars are those sugars which are added to foods or drinks, not the natural sugar found in fruits and vegetables. The amount of free sugar that a child should have is 19 grams per day for those aged 4-6 and 24 grams for those aged 7-10. So again it is easy to see that if children are drinking energy drinks over and above sugar that will be present in food they eat, it would be easy to go over the recommended amount of sugar each day.

    Selling Energy Drinks to Children

    There are currently voluntary bans for shops not to sell energy drinks to children under 16, but there are calls to make this illegal. Some schools have already banned children from bringing these drinks into school.

My students and I were ready for a challenge — a trip to Costa Rica. As we were waiting at the airport, we talked about our hopes and fears for our ten-day trip. My students worried about homesickness and felt uneasy with their homestay families. But strange foods or meeting new people didn't concern me. What terrified me was the best part of the trip — a zip lining (滑缆绳) flight over the jungle valley bordering Arenal Volcano. I made a secret pact (协议) with myself to find an excuse to get out of it at the last minute.

    When the fateful day arrived, we got to the peak to enjoy the breathtaking view of the volcano. When seeing the activity, my students raised a cheerful shout. How I wished I had had the same feeling as them. However, I was afraid of heights.

    My student Eileen sidled up to me. Her face was pale. "I'm scared," she whispered. "Will you stay back with me?" Here was my chance! I could get out of zip lining and still save face!

    "I'm scared, too," I said quietly.

    "Yeah," she said. "I thought you would be the right person to ask because you are really white, and you are sweating." Her words woke me up, and something clicked into place. If I couldn't step outside of my comfort zone, how could I ask the kids to do so?

    "Maybe we should give it a try," I said. I felt a little sick, but I couldn't believe my body was actually moving toward the launch point.

    "Come on," I said.

    "OK," she agreed.

    Eileen zipped past me, screaming with fear or delight, which I was not sure of. Once she was across, I followed. The attempt was not as terrible as I had thought. From that moment on, I knew there was nothing to fear as long as I walked out of my comfort zone and had a try.
