现看一个句子：
The small amount of rain last year affected the growth of crops.

读完这个句子，意思很清楚：“去年雨水太少，农作物歉收。”按说这就完了，不过突然想起来还应该多看看别的句子，丰富一下。于是去yahoo英文站搜索引擎用关键词 affected rain搜索，得到这样的结果：

1、EPA's Clean Air Markets - Acid Rain Permitting Fact Sheet

第一条文字不很浅显，反正不感兴趣。看了第二条，对“酸雨”的认识又多了一层。知道了酸雨一般PH值小于5.6。并且，如果作文要求以酸雨为题，这样的一小段话复述、想象一下，可以作为素材的呢！

baffle
vt.
困惑, 阻碍, 为难

第一步：想象一下，哪些人会“困惑，阻碍，为难”。
我首先想到的学生，在考试的时候。
第二步：以 exam baffle为关键词（没有用student作为关键词，是因为对主语限制为student后，得到的结果就非常有限），在yahoo里搜索，得到：
我晕～搜索到一道英文物理试题：

21. In a lecture experiment, we listened to a small unmouted speaker and compared its sound with that when a baffle was attached to the speaker. When there was no baffle, sound waves from the back of the speaker could propagate in the same (forward) direction as waves from the front of the speaker. The wave property that allowed waves from the back to bend around toward the front is called
A.   refraction       B.   diffraction       C.   deflection       D.   construction       E.   interference
衍射

不行，再想一个。我们让谁最 baffle？嘿嘿，当然是我们的父母parents了！
改关键词为：parents baffle，再用yahoo搜索（蓝色字体我的试译）

New Methods Can Baffle Parents
新课标让家长困惑
By MARILYN BROWN mbrown@tampatrib.com
Published: Oct 10, 2004

TAMPA - Little wonder some parents don't recognize much in their children's math homework.
Today's math isn't always about getting a specific answer, but about how you get the answer, Hillsborough educators say.
家长很困惑，他们搞不懂他们孩子的数学作业了？？``It's not three plus five is eight anymore,'' says Edie McDermott, a second-grade teacher at Tampa's Cannella Elementary School who has taught for 18 years. ``You learn to look at it a different way.''
“再也不是3+5＝8了”埃迪说，她是一位二年级的老师，在TCE学校教了18年了，“我们要用另外一种方式来学习了”
The emphasis is on knowing why you are doing math before tackling calculations, says Lia Crawford, Hillsborough County Schools elementary math supervisor.
为什么这么计算是新课标的重点，克劳佛督察?说道。
Teachers use flash cards, but the cards are triangular and require students to add, subtract, multiply and divide numbers from all three corners. That shows a connection among those processes.

They no longer take time to drill multiplication tables, so children who don't know them don't take time away from those who do.

Ultimately, one of the major goals is to succeed on the annual Florida Comprehensive Assessment Test, which checks for higher-level thinking skills and reasoning.

``There's not just one way to find an answer,'' said Shana Tirado, math resource teacher at Tampa's Lomax Elementary Magnet School. ``And there's not always just one right answer, if you can justify how you got there.''
“没有标准答案”，“需要的是你的思维方式”
Often parents need help with the new methods so they can help their children with homework, so schools hold family workshops.

``They are really surprised when they see how it's changed,'' said Oak Park Elementary Principal Joyce Miles. ``A lot say they think this is really neat.''
“很多人说，新课标真棒！”呵呵

Create Intricate Strategies and Besiege the Enemy in Besieger

by Louis Bedigian

Players can build and train enormous armies in this promising real-time strategy game.  Internal Producer Pavel Grodek tells us how it抯 done.

To besiege or not to besiege.  Surely those who are besieged will beseech help.  Those who do it will be deemed beleaguers; harassers of the unprepared, the apparently innocent.  But in war if you make the wrong decision you抮e considered incompetent ?if you make the right one you抮e considered incredible.

Surely the effects of an incredible action will be indelible.  But what might be a memorable experience to some is misery to another.

Knowing this, can you go into battle, ready to fight, ready to charge?

Heed these words young straggler, for one day you will ponder whether or not you should besiege.

想起了当年街机被敌人围攻、三国志里面用张飞和关羽围攻小胖的情景……

It reminded me of that wonderful poem by Eleanor Scates Dulany:

          Give me a home that we have built

                    With dreams and sacrifice and song,

          Where youth and age have laughed and wept,

                    And love has mellowed every wrong.

Whose walls have echoed with the ring

                    Of children’s voices in and out,

The merriment of festive board,

          And human kindness round about.

Give me a home where selflessness

          Is spent in doing little things

That rate so high in happiness

          The whole house breathes the peace it brings.

Then give me grace to understand

That men may build from house to dome

With all the art of masonry----
But only love can build a home.

                                        Eleanor Scates Dulany
