Good afternoon. Ladies and gentlemen.

Welcome to this year’s English speech competition. Taking part in English speech competition is a helpful way to learn English. While we fully prepare for the competition, we can improve our abilities of listening and speaking and develop a good habit of reading English. In the process of the competition, you should pay special attention to the following rules. First, you should finish your speech in five minutes. Second, you try your best to express yourself in English fluently. Finally, you should have a good English pronunciation.

I hope that the English speech competition will be a great success!

【思路分析】

这是一篇很实用的演讲稿。旨在考查学生在实际生活中在某个具体场合下灵活使用英文来表达自己思想的能力。考查学生学以致用。本演讲稿有三个写作要点：1. 说明比赛的意义，如提高英语听说能力，养成读书的习惯等；2. 说明比赛的注意事项，如每人演讲不超过5分钟，语言流利，发音准确等；3. 预祝比赛圆满成功。然后自由发挥写出适当的结尾。

【较高级的结构和短语】form/develop a good habit of doing…; take part in; The first thing we can do is to make…; pay attention to 等。

二、天津高考卷2009详解数学选择题9、10

(9) 画图知 准线x=-1/2 又∵BF=2 ∴B点横坐标为3/2 ∴B（3/2，负根号3） 设直线AB为x=ky+根号3 代入抛物线得 y^2-2ky-2根号3=0 ∴y(a)*y(b)=负2根号3 ∴y(a)=2 S△BCF:S△ACF=BC：AC=2:x(a)+1/2=4:2x(a)+1=4:y(a)^2+1=4:5 答案为A （10）移项整理后得 （1-a²）x-2bx+b²>0 由于解集有限 ∴开口向下 1-a²<0 又∵条件1+a>0 ∴ a>1 [题外话： 其实这时候我觉得已经可以选C了 你的答案不对 C应该是1
