Recently,people in US education have gotten extremely worried because a new report has shown that American students have a math problem.

    The 2015 Program for International Student Assessment（评估）(PISA) shows math scores in the US getting lower and no improvement in science or reading.PISA tests 15-year-olds from different countries and regions in their math,science and reading skills.About 540,000 students from 72 countries and regions took part in the assessment in 2015.

    US scores in reading and science were about the same as three years ago,leaving Americans near the middle of the bigger group.But the situation in math is much more worrying.The US average score was 470,be;ow the OECD（经合组织）test average of 490,meaning the US was No.40 among the 72 countries and areas.It was 12 points lower than in 2012 and 18 points lower than in 2009.So,what is going on with American students' math skills?

    One reason may be that the US does not teach math in enough depth."Students are often good at answering the first part of a problem in the United States,"said Andreas Schleicher,director of education and skills at OECD."But as soon as students have to go deeper and answer the more complicated part of a problem,they have difficulties."In comparison,many high-performing countries and regions in math teach a lot less but focus in much greater depth, especially when you look at East Asia,Japan and Singapore,according to Schleicher.

    Another reason may be the fact that many people in the US are unwilling to travel to foreign countries to learn better teaching practices."One of our biggest challenges in the US is that the teachers are not going out and seeing what high-performing countries do differently,"said Wendy Kopp,who started Teach for America,in a news program.

    America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while - then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet n friend. We may take days off to net as guides to our foreign friends. The Americans, however, express their welcome usually at homos, but truly can not manage the lime to do n great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, worm and real. We will find ourselves treated hospitably.

    For the Americans, it is often considered more friendly lo invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

    Australia was first used as an island prison by Britain to solve their problem of having a fast growing prison population. These early settlers were those who were sent from all over Great Britain, including Ireland, Wales, and Scotland. Later events, such as the gold rush, caused several waves of immigration (移居) from Europe, Asia and other parts of the world. It is commonly thought that Australians are offspring (后代) of those criminals (罪犯)! In fact, only a part of Australians are those criminals' offspring. Also, in those days, people could be put into prison or sent to Australia for small crimes, like stealing a loaf of bread. Today Australia is home to the largest Greek and Italian communities in the world, outside Greece and Italy. This has helped the Australian accent develop.

    Australian English was created by the first generation of children born in the new area. Since they talked with people who have different accents, they began to speak a distinct dialect of English that was to become the language of the nation. These differences were first noted by late arrivals in the early 1800s, and the language sounds like Cockney English, spoken by the working­class in London.

    Soon, words from native languages were to become part of the Australian English. Here are some words you may consider them to be Standard English. In fact, they are from native Australian languages!

    The names of many places and animals, including Canberra (the Australian capital, meaning "meeting place" in a local language).

    Hard yakka — meaning "hard work", coming from the language of the Brisbane area.

    Cooee — a call used traditionally by native Australians to attract attention, because the sound can travel long distances.

    Bung — meaning "dead", but also used to mean broken or useless, for example, "He has a bung eye".

    With the possible exception of equal rights, perhaps the most controversial issue across the United States today is the death penalty. Many argue that it is an effective deterrent (威慑) to murder, while others maintain there is no convincing evidence that the death penalty reduces the number of murders.

    The principal argument advanced by those opposed to the death penalty, basically, is that it is cruel and inhuman punishment, which is the mark of a brutal society, and finally that it is of questionable effectiveness as a deterrent to crime anyway.

    In our opinion, the death penalty is a necessary evil. Throughout recorded history there have always been those extreme individuals in every society who were capable of terribly violent crimes such as murder. But some are more extreme than others.

    For example, it is one thing to take the life of another in a fit of blind rage, but quite another to coldly plot and carry out the murder of one or more people in the style of a butcher. Thus, murder, like all other crimes, is a matter of relative degree. While it could be argued with some conviction that the criminal in the first instance should be merely separated from society, such should not be the fate of the latter type murderer.

    The value of the death penalty as a deterrent to crime may be open to debate. But the overwhelming majority of citizens believe that the death penalty protects them. Their belief is strengthened by evidence which shows that the death penalty deters murder. For example, from 1954 to 1963, when the death penalty was consistently imposed in California, the murder rate remained between three and four murders for each 100,000 population. Since 1964 the death penalty has been carried out only once, and the murder rate has risen to 10.4 murders for each 100,000 population. The sharp climb in the state's murder rate, which began when executions stopped, is no coincidence. It is convincing evidence that the death penalty does deter many murderers. If the bill reestablishing the death penalty is banned, innocent people will be murdered—some whose lives may have been saved if the death penalty were in effect. This is literally a life or death matter. The lives of thousands of innocent people must be protected.

Channel Islands

The two main islands, Jersey and Guernsey, are remarkable in that they present a combination of enjoyment peace and quiet. Neither island is very big (only ten miles long) and so all parts of these coasts are easily reached from the main centers — St. Helier and St. Peter Port. In both these towns and particularly in Jersey's St. Helier are concentrated (集中) the amusements of really big resorts (休养地). The nearness of France gives a continental atmosphere; the weather is far better than that in England. The other three islands, Jethou, Herm and Sark are small and quiet.

Isles of Scilly

The islands are really small and quiet; and the weather is warm but windy. The islands are excellent for those who enjoy exploring (探险) small inlets (水湾), creeks (小溪) and bays on foot, or even better in a boat.

Isle of Wight

The island is 24 miles across and therefore quite large. The scenery is good and varied. The resorts are neither overlarge nor showy. The crowds seem content with entertaining but quieter holidays. The island has the best sunshine record in Britain.

Isle of Man

An island with unique atmosphere — in some indefinable (难以描述的) way it is different from England, Scotland or Wales. Thirty miles long, with good roads and good public transport, the mountains, hills and glens (幽谷) are easily reached. Douglas is a major British resort and other resorts are lively.

It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.

My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I'm so glad I did.

On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big hums (脊背) in the distance.

On approaching them, we saw it was a mother whale with her baby. We couldn't believe it—there aren't any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.

The little baby whale—actually as big as our boat—was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools (漩涡) and waves. "She's trying to help her baby, but on the wrong side," my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, sometimes rising from the water right beside us to breathe—and to give us a trusting (信任的) look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.

In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day. Nearly four decades later, I still look back fondly to that golden day at sea.
