A great man died today. He wasn't a world leader or a famous doctor or a war hero or a sports star. He was not a rich businessman, and you will never see his name in the front pages. But he was one of the greatest men who ever lived. He was my father.
I guess you might say he was a person who was never interested in getting money or receiving honors. He did ordinary things like paying his bills on time, going to church on Sunday and serving as an officer in his company. He helped his children with their homework and drove his wife to do shopping on Thursday nights.
Tonight is my first night without him. I don't know what to do myself. I am sorry now for the times I didn't show him the proper respect. But I am thankful for a lot of other things.
I am thankful that God let me have my father for fifteen years. And I am happy that I was able to let him know how much I loved him. That wonderful man died with a smile on his face and fulfillment in his heart. He knew that he was a great success as a husband, a father, a brother, a son and a friend. I wonder how many millionaires can say that.
1. The writer thinks his father was a great man.
2. The writer loves his father for everything except that he was not rich.
3. The Writer was fifteen years old when his father died.
4. In the writer's opinion, many millionaires can say that they are successful husbands, fathers,
brothers, sons and friends.

Last year, I was invited to attend a party for "Tuesday's Child". an organization that helps children with the AIDS virus. I was asked to attend because I am on a TV show. I went there because I care.
At the party, they had all kinds of small rooms. I went into a special one. In this room, anyone could paint a square. They gave everyone paints in bright, beautiful colors and asked the kids to paint something beautiful. As I looked around at all the squares, I saw the pictures were all bright, except one.
The boy sitting next to me was painting a heart, but it was dark, empty, and lifeless. It lacked the bright colors that other children used.
At first I thought maybe he took the only paint that was left and it just happened to be dark. But when I asked him about it, he said his heart was that color because his own heart felt dark. I asked him why and he told me that he was very sick and his mother was very sick, too. He said that his sickness was not ever going to get better and neither was his mother’s. He looked straight into my eyes and said, "There is nothing anyone can do to help."
I told him I was sorry that he was sick and I could certainly understand why he was so sad. I could even understand why he had made his heart a dark color. But I told him that it isn't true that there is nothing anyone can do to help. Other people may not make him or his mother better but we call do things like giving him or her hugs. Then I
hugged him for a long time. I thought my own heart would burst with the love I felt for this sweet little boy. After that, I asked him if he felt any better. He said he did, but he was still sick and nothing would change that. I walked away felling sad.
As I was getting ready to head home, I fell a tug on my jacket. I turned around and the little boy was standing there with a smile on his face. He told me, "My heart is changing colors. It is getting brighter. I think those hugs really work."
On my way home, I felt my own heart had changed into a brighter color.

This letter was sent to a newspaper in Germany.
13 October 26. 2008
Dear Editor,
I am writing to ask what has happened to our youth. They axe not as polite, hard-working or clever as my generation. I will give you two examples.
Last Friday, I got on the underground at 9:15am.It was very busy so there were no free seats. There were some teenagers sitting on the seats nearest me. I don't know why they were not at school. They were talking loudly and laughing. It was difficult to read my newspaper with all the noise. A heavily pregnant woman and her daughter got on at the next stop, with lots of shopping bags. I expected the teenagers to let them sit down. They saw the woman but did nothing. I had to ask them to give her a seat. They reluctantly did so but gave me a rude look. I got off at the next stop and was glad that the teenagers didn't follow me.
Last Saturday, I had dinner with my friend's family. I expected to meet his children, who I hadn't seen for ten years. During dinner, we started talking about world politics. It soon became clear that they didn't know much. They couldn't tell me the name of the King of Spain or the President of Italy. All they knew about was the internet and which
singers were the most beautiful. In my day, students knew the kings, queens and presidents of every country in Europe.
I worry about the future of Germany. How could these young people become reliable workers and parents? They sit around McDonald's after school instead of going to the library as I did at their age. Maybe they have too much money. Perhaps another reader can give us an idea about what to do with this "lost generation"
Franz Vogts,
Hamburg
1. In what three ways does Mr. V ogts think young people today are worse than young people before?
2. What were the teenagers near Mr. V ogts doing?
3. What did Mr. Vogts think should happen when a pregnant woman got on the train?
4. How do you know the teenagers were not satisfied with Mr. Vogts?
5. Why was Mr. Vogts disappointed at the dinner?

2009年上海外国语大学英语综合及答案
上海外国语大学2009年英语语言文学英语综合考研试题 英语综合改错 A fairly standard consensual definition is "a relatively permanent change in behavior (sic.; it's American of course) that results from practise." This is of course arguable, particularly the "practice" criterion. Others would accept changes in "capability" or even simple "knowledge" or "understanding", even if it is not manifest in behaviour. It is however an important criterion that "learned" behaviour is not pre-programmed or wholly instinctive (not a word used much nowadays), even if an instinctual drive underpins it. Behaviour can also change as a result of maturation-simple growing-up-without being totally learned. Think of the changing attitude of children and adolescents to opposite-sex peers. Whatever the case, there has to be interaction with the environment. Even if psychologists ever agree about what learning is, in practice educationalists won't, because education introduces prescriptive notions about specifying what ought to be learnt, and there is considerable dispute about whether this ought only to be what the teacher wants the learner to learn (implicit in behavioural models), or what the learner wants to learn (as in humanistic models). 2009英语语言文学完形填空全文 Obtaining Linguistic Data Many procedures are available for obtaining data about a language. They range from a carefully planned, intensive field investigation in a foreign country to a casual introspection about one's mother tongue carried out in an armchair at home. In all cases, someone has to act as a source of language data - an informant. Informants are(ideally) native speakers of a language, who provide utterances for analysis and other kinds of information about the language(e.g. translations, comments about correctness, or judgements on usage). Often, when studying their mother tongue, linguists act as their own informants, judging the ambiguity, acceptability, or other properties of utterances against their own intuitions. The convenience of this approach makes it widely used, and it is considered the norm in the generative approach to linguistics. But a linguist's personal judgements are often uncertain, or disagree with the judgements of other linguists, at which point recourse is needed to more objective methods of enquiry, using non-linguists as informants. The latter procedure is unavoidable when working on foreign languages, or child speech. Many factors must be considered when selecting informants - whether one is working with single speakers(a common situation when languages have not been described before), two people interacting, small groups or large-scale samples. Age, sex, social background and other aspects of identity are important, as these factors are known to influence the kind of language used. The topic of conversation and the characteristics of the social setting(e.g. the level of formality) are also highly relevant, as are the personal qualities of the informants(e.g. their fluency and consistency). For larger studies, scrupulous attention has been paid to the sampling theory employed, and in all cases, decisions have to be made about the best investigative techniques to use. Today, researchers often tape-record informants. This enables the linguist's claims about the language to be checked, and provides a way of making those claims more accurate('difficult' pieces of speech can be listened to repeatedly). But obtaining naturalistic, good-quality data is never easy. People talk abnormally when they know they are being recorded, and sound quality can be poor. A variety of tape-recording procedures have thus been devised to minimise the
