1. (2017·杭州模拟) 阅读下面材料, 在空白处填入适当内容 (一个单词）或括号内单词的适当形式。讲答案填写在答题纸的相应位置。
       What's the most important thing for you to have in your life? Somebody (mention)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 (number)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 , .
       Then what else? Don't be worried. You can always find an answer a problem in your life, you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for(you): 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 one will have a change for the better after one has (change)one's attitude.
       When you change your manner and became friendly towards others, you'll meet (much)smiling faces towards you. In the same way, if you take a positive attitude towards failure, you'll find it's also rewarding it has caused you losses.
