There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved*.
I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not enjoy the long train journey and had brought along many magazines to read and reread. I looked about the train. There was not one familiar face. I sat down and started to read magazines.
It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just a city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond* the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive, I decided to wave back.
From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.
The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. When my uncle arrived, I threw my arms around him to give him a warm hug. I had never done this before. He seemed surprised and then his face warmed up with a huge smile. We walked arm in arm to his car.
I looked forward to the return journey.
小題1:The writer expected the train trip to be ______.
A.dangerousB.pleasant C.excitingD.boring
小題2: What impressed the writer most during her train trip?

小題3:Which of the following statement is TRUE according to the passage?.
A.The people on the train were the villagers’ favorite relatives.
B.The writer spent the whole journey reading magazines.
C.The writer thought he enjoyed the train journey at last.
D.The writer’s uncle gave him a warm hug with a huge smile.
小題4: What's the best title of the passage?

People at home keep asking me, "Is it hard to learn Chinese? Why have you learned it so well?" Well, there's one thing that makes Chinese easy to learn: there are so many people to talk to. You've probably heard that it's the most spoken language. Today it's also one of the most written languages online. And with so many Chinese people interested in learning English, it couldn't be easier to find a friend for language learning. You just have to know where to look for them.
The really good place to look for them is QQ. QQ has the same status(地位) in China as AIM (AOL Instant Messenger) does in the US. It is reported that at any moment, up to 9,000,000 people are using QQ. They're at work, or in a web café(網(wǎng)吧), or at home, and the information of the users can be found. If you sign on with your address set to "abroad", you'll soon find that many thousands of them are interested in speaking to you! This is a great way for you to learn Chinese, and for them to learn English. I think that it's a very interesting way of cultural contact(文化交流), too, for ordinary people from around the world to be able to have one-on-one contact.

A.why his family members want to learn Chinese

What’s the most important thing for you to have in your life? Somebody mentions(提到) hard-work, others suggest knowledge, love and luck.
If you arrange the 26 English letters alphabetically(按字母表的順序)and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11="98," meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5="96," while love:12+15+22+5="54," and luck : 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money or prayer(祈禱)? They can’t , either.
Then what else? Don’t be worried.You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude(態(tài)度).Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100,a full mark.
Different attitudes lead to different courses of life. Most times people hope for a better life. It is possible that one will have a change for the better after one has changed one’s attitude.
When you change your manner and became friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive (積極地) attitude towards failure(失敗),you’ll find it’s also rewarding though it has caused you losses.
小題1:What is the mark of the word “money”?
A.54B.72C.96D.100
小題2:In the writer’s opinion, what is the most important thing in a person’s life?
A.Hard-work.B.Knowledge.C.Money.D.Attitude.
小題3:According to the passage, if you meet with problems, the best way out is to _______.
A.a(chǎn)sk for help from othersB.say your prayers to God
C.change your attitudeD.try maths-solving methods (方法)
小題4:From the passage we can learn that ______.
A.different attitudes come from different courses of life
B.mathematics can solve every problem easily in our daily life
