    What's the most important thing for you to have in your life? Someboy mentions hard-work, others

suggest knowledge, love and luck.

    If you arrange the 26 English letters alphabetically (按字母表的顺序) 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 (祈祷)? 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 (态度).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 betterr 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 (积极地) attitude towards failure (失败), you'll find

it's also rewarding though it has caused you losses.

Last Saturday the students of our class made a bike trip of Wanping, a small town by the Taihu Lake. We set off earlier in the morning. After getting to the town, we had visited some places of interest. At noon, we had picnic near the lake. Everybody was attracted with the beautiful scenery and we took a lot of picture. In the afternoon, some of them went fishing, some flew kites, and the others rowed boats on the water. We both had a wonderful time! It was a pleasant trio fir us, during which the boys were offered the girls a lot of help. We have learned to help, understand and sharing with others. In a word, we have got quite a lot from it.
