Wouldn’t it be great if you could just look up at the sky and read the weather forecast right away? Well, you can. The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists(气象学家).
Meteorologists use much more information than just the appearance of the clouds to make their forecast. They collect data(数据)from all over the world. Then they put it into powerful, high speed computers. This does give the meteorologists an advantage, because they can track(追踪)weather patterns as they move from west to east across the country. But you have an advantage, too. You can look at the sky and get your data directly. A meteorologist uses a computer forecast that’s several hours old to make a local forecast.
What are you seeing when you look at a cloud? “A picture of moisture(水汽)is doing in the atmosphere,” says meteorologist Peter Leavitt. There’s moisture throughout the atmosphere. Most of the time you don’t see it, because it’s in the form of an unseeable gas called water vapor. Sometimes, the temperature of the air gets cold enough to cause the waster vapor to change to liquid water. It’s called condensation(凝结), and we see it happen all the time (for example, when humid air from the shower hits the cold glasses of a mirror). When enough water vapor condenses(冷凝), droplets(小滴)come in the air. These droplets scatter(分散) light. A cloud is seen.
Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere. You should begin to notice patterns. Certain clouds, following each other in order, can signal an approaching storm. But don’t take our word for it; see for yourself.
According to the passage, an ordinary person might read the weather forecast as well as meteorologists _________.

A.with some simple practice looking up at the sky
B.with the help of the high-speed computers
C.through complex (复杂的) instruments
D.by visiting a weather station

Meteorologists can make their weather forecast     .

A.by using information of the appearance of the clouds only
B.by collecting data from parts of the world
C.by collecting and analyzing(分析)the data
D.by watching the sky

According to the passage, your advantage in weather forecast is that     .

A.you have a high-speed computer
B.you observe the sky and get your data directly
C.you have more instruments at home
D.you can track weather patterns as they move from west to east across the country

This passage mainly tells us about how to    .

A.train ourselves as meteorologists
B.be an assistant to a meteorologist
C.forecast the weather by ourselves
D.broadcast the weather forecast

In 2006, the UK government started to allow universities in England and Wales to charge British students tuition fees. More than 80 percent of students in England and Wales now take out a student loan in order to go to university. They use the loan (贷款) to pay for tuition fees, books and living expenses. Although the interest on student loans is quite low, it begins as soon as the student receives the loan. The average student in England and Wales now graduates from university with debts of around £12,000. Students of medicine usually have debts of more than £20,000. That is a lot of money. It means graduates cannot afford to buy a house for many years. They even struggle to pay rent on a flat, because they have to start paying back the student loan after graduating. If you start to earn over £15,000 a year, the government takes repayments directly from your monthly salary. Is it any surprise, therefore, that the average British person does not leave their parents’ home until they are 30 years old?
You might think that a British person with a degree will find it easy to get a well-paid job. However, most people in white-collar jobs seem to have a degree these days, so there is a lot of competition. Also, British companies tend to value work experience over a piece of paper. Like everyone else, graduates usually have to start at the bottom and work their way up. That can be very frustrating for them, since they are often over-qualified for the work they are doing. While at university, they have dreams of getting an exciting, challenging job. Therefore, life after university ends up being quite disappointing for a lot of graduates.
All of the above is beginning to make British people question whether a university degree is really worth the money.
What's the best title of this passage?

35 years old

Disease, poverty, hate, love-Charles Dickens’ stories opened his readers eyes to the most important themes of his age. Two hundred years on, his stories still speak volumes across the world, proving that Dickens’ legacy(遗产) was far greater that just “great-literature”. February 7 marks the 200th anniversary of the writer’s birthday. To mark this date, BBC writer Alex Hudson listed six things Dickens gave the modern world. Let’s take a look at two of them.
A White Christmas
Dickens is described as “the man who invented Christmas” - not the religious festival, but the cultural aspects that we associate with the festive season today. In the early 19th century, Christmas was barely worth mentioning, according to critic and writer Leigh Hunt. The committee which ran the Conservative Party even held ordinary business meetings on Christmas Day-unthinkable in the West nowadays, when everyone but the most necessary workers takes at least three days off. Many people believe that Dickens’ popular descriptions of the festive period became a blueprint for generations to come. In his classic novel, A Christmas Carol, he not only put forward the idea of snow at Christmas, but also painted a picture of glowing warmth-“home enjoyments, affections and hopes”. In his biography of Dickens, Peter Ackroyd wrote: “Dickens can be said to have almost single-handedly created the modern idea of Christmas.”
“Dickens” poverty
Dickens was one of the first to take an honest look at the underclass and the poor of Victorian London. He helped popularize the term “red tape” to describe situations where people in power use needless amounts of bureaucracy(官僚作风) in a way that particularly hurts the weaker and poorer members of society.
“Dickensian” has now become a powerful word for describing an unacceptable level of poverty. In 2009, when the president of the Association of Teachers and Lecturers in the UK wanted to talk about poverty in some areas of Britain, she did not use words like “terrible” or “horrific”, but rather described it as “life mirroring the times of Dickens”.
The article is mainly about.

A.a brief introduction to Charles Dickens’
B.the characters in Charles Dickens’ stories
C.Charles Dickens’ impact(影响力) on the world
D.Charles Dickens’ achievements in literature

A.Because he created both religious and culture festival.
B.Because one of his novels helped to shape Christmas celebrations.
C.Because his novels have something to do with Christmas.
D.Because he was the first man to have proposed celebrating Christmas.

We can learn from the passage that.

A.Charles Dickens’ novels reflect(反映) the true life at his age
B.Dickensian is widely used to describe the Christmas
C.Every person can take three days off for Christmas
D.The theme of Charles Dickens’ stories is about poverty

What can we infer from the passage?

A.Dickens gave the modern world six things.
B.Dickens is still popular today in Britain.
C.Dickens invented Christmas
D.Agreements made by the underclass of society

In the year after my mother left us, my father was 42 and he knew that he wasn’t going to make it to 43. He wrote a letter to me and hoped that something in it would help me for the rest of my life.
Since the day I was 12 and first read his letter, some of his words have lived in my heart. One part always stands out. “Right now, you are pretending to be a time killer. But I know that one day, you will do something great that will set you among the very best.” Knowing that my dad believed in me gave me permission to believe in myself. “You will do something great.” He didn’t know what I would be, and neither did I, but at times in my life when I’ve felt proud of myself, I remember his words and wish he were here so I could ask, “Is this what you were talking about , Dad ? Should I keep going?”
A long way from 12 now, I realize he would have been proud when I made any progress. Lately, though, I’ve come to believe he would want me to move on to what comes next: to be proud of , and believe in somebody else. It’s time to start writing my own letters to my children. Our children look to us with the same unanswered question we had. Our kids don’t hold back because they’re afraid to fail. They’re only afraid of failing us. They don’t worry about being disappointed. Their fear ---- as mine was until my father’s letter---- is of being a disappointment.
Give your children permission to succeed. They’re waiting for you to believe in them. I always knew my parents loved me. But trust me: That belief will be more complete , that love will be more real, and their belief in themselves will be greater if you write the words on their hearts :“Don’t worry; you’ll do something great .”Not having that blessing from their parents may be the only thing holding them back.
