Off the coast of Hong Kong, there are numerous beautiful places that have long stay hidden, just waiting to be discovered by travelers. We've done the hunting for you.

Tap Mun

    Located north of the Sai Kung island, Tap Mun is home to a remote fishing, community with a population of less than a hundred. Tap Mun is also widely known as Grass Island, and it's easy to see why — this 1.7sq km island is an expense of grassy hill populated by wandering cows, a perfect scene to set a milk advertisement.

    Tap Mun is highly sought after as a spot for both camping and kite-flying, while also boasting several rocky beaches. For a relaxing afternoon, take a walk along the 2km footpath and slowly take in the panoramic(全景的) 360-degree view while enjoying the cool breeze.

Tung Ping Chau

    For a rugged(崎岖的) island getaway, set off for a trip to Tung Ping Chau — an offshore island sitting in splendid isolation in Mirs Bay on the northeastern side of Hong Kong. As a part of the Hong Kong Geopark, Tung Ping Chau is among the eight sites specially chosen for conservation in light of its special geological significance. Its rich marine life also led to its designation(指定) as one of Hong Kong's four marine parks.

Po Toi

    Located just three kilometers away from Hong Kong Island's southeastern tip, Po Toi is a quiet place that will make you feel completely isolated from modern life. While just a stone's throw away from the busy life of Hong Kong, Po Toi seems to be miles away from the busy city life.

    Take a leisurely stroll (闲逛) along the main path on the island, as you approach a lighthouse located on the sides of the cliff. Along the way, do not miss the dramatic and unusual rock formations as you are amazed by the glory of the famous Turtle Climbing up the Mountain, Monk Rock, and Palm Cliff.

A typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours' sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the problems arise because our sleep patterns are not fixed, and they change as we grow.

So a later school start time could help to solve this problem, by ensuring to get their eight plus hours of sleep and react properly to their body's natural rhythms (规律). There has been a general shift over the past 25 years to shorten the school day. This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks.

Later start times could help teens' grades and health. This is mainly because it makes the management of children easier. Supervising (监管) hundreds of children “playing” requires effective staffing (人员配备). And there is always the fear that behavior worsens during breaks. So the theory goes that having them in class and strictly supervised must be better.

    But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are thrust into ancient history. And teaching staff also transit from one class to another, with hardly a rest or time to refocus.

    Clearly rethinking the school day could benefit everyone involved. Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. For teachers, it could also mean a less stressful day all around and what could be better than that?

阅读下列短文，从每题所给的四个选项 （A 、B 、C  和 D ）中，选出最佳选项。

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were on holiday." I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holidays" is said "vacaciones". So they did not go to house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to houses where the sign said "NO VACANCIES", because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means "fun". In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, Thank you".

    Dry Ice is a unique substance which has many uses. Essentially, dry ice is frozen CO2. The first report of what we now call dry ice came from the French chemist Charles Thilorier in 1834. In 1924, the Drylee Corporation of America named the solid form of CO2 as "Dry Ice", which is what it is popularly called today.

    At normal atmospheric pressure, CO2changes directly from solid to gas. It skips the liquid phase（阶段）which makes regular ice wet. Frozen CO2is also much colder than regular ice. But regular ice freezes at 32 degrees Fahrenheit, CO2 changes from gas to solid at -109.3 degrees Fahrenheit. This extremely cold temperature makes it very dangerous to handle with bare hands. It can cause frostbite in a very short period of time.

    Dry ice has been used for a variety of purposes throughout the past century. Its primary use is to refrigerate food when electrical refrigeration isn't available. Through the process of sublimation (when CO2 changes from solid to gas), it can maintain cold food for a long time.

    If you've ever been to a play and seen heavy fog on the ground, it is likely that you have seen dry ice in action. This effect can be achieved because CO2 is heavier than air, so evaporated （挥发的）CO2 will sink and accumulate on the ground.

    Another interesting use for this substance is to bait（诱杀）insects like mosquitoes. These insects have sensors which guide them to CO2. They find the high concentration of CO2 in dry ice quite attractive.

    Mars has long been a mystery for human beings. We have been looking for evidence of life on Mars. In the 1960s scientists guessed that the polar ice cap of Mars was made of frozen CO2. More recent observations have shown that while the topmost layer consists of frozen CO2, the most of it is probably regular frozen water.

    A newly-published study has shown that loneliness can spread from one person to another, like a disease.

    Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental( 心 理 的 ) health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 persons are taking part.

    Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.

    University of Chicago psychologist (心理学家) John Cacioppo led the recent study. He and other researchers tried to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.

    Having a social connection with a lonely person increased the chances that another person would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone's loneliness.

    The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.

    The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.

    Loneliness has been something to do with health problems like sadness and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.

    The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.

    The Frick Collection (5th Avenue and E. 70th Street)
