阅读下面文字,回答问题。

  ①他对高妈有相当的佩服,觉得这个女人比一般的男子还有心路与能力,她的话是抄着根儿来的。他不敢赶上她去闲谈,但在院中或门口遇上她,她若有工夫说几句,他就很愿意听她说。她每说一套,总够他思索半天的,所以每逢遇上她,他会傻傻忽忽地一笑,使她明白他是佩服她的话,她也就觉到点得意,即使没有工夫,也得扯上几句。

  ②不过,对于钱的处置方法,他可不敢冒儿咕咚地就随着她的主意走。她的主意,他以为,实在不算坏;可是多少有点冒险。他很愿意听她说,好多学些招数,心里显着宽绰;在实行上,他还是那个老主意——不轻易撒手钱。

  ③不错,高妈的确有办法:自从她守了寡,她就把月间所能剩下的一点钱放出去,一块也是一笔,两块也是一笔,放给作仆人的,当二三等巡警的,和做小买卖的,利钱至少是三分。这些人时常为一块钱急得红着眼转磨,就是有人借给他们一块而当两块算,他们也得伸手接着。除了这样,钱就不会教他们看见;他们所看见的钱上有毒,接过来便会抽干他们的血,但是他们还得接着。凡是能使他们缓一口气的,他们就有胆子拿起来;生命就是且缓一口气再讲,明天再说明天的。高妈,在她丈夫活着的时候,就曾经受着这个毒。她的丈夫喝醉来找她,非有一块钱不能打发;没有,他就在宅门外醉闹;她没办法,不管多大的利息也得马上借到这块钱。由这种经验,她学来这种方法,并不是想报复,而是拿它当做合理的,几乎是救急的慈善事。有急等用钱的,有愿意借出去的,周瑜打黄盖,愿打愿挨!

  ④在宗旨上,她既以为这没有什么下不去的地方,那么在方法上她就得厉害一点,不能拿钱打水上飘;干什么说什么。这需要眼光,手段,小心,泼辣,好不至都放了鹰。她比银行经理并不少费心血,因为她需要更多的小心谨慎。资本有大小,主义是一样,因为这是资本主义的社会,像一个极细极大的筛子,一点一点地从上面往下筛钱,越往下钱越少;同时,也往下筛主义,可是上下一边儿多,因为主义不像钱那样怕筛眼小,它是无形体的,随便由什么极小的孔中也能溜下来。大家都说高妈厉害,她自己也这么承认;她的厉害是由困苦中折磨中锻炼出来的。一想起过去的苦处,连自己的丈夫都那样的无情无理,她就咬上了牙。她可以很和气,也可以很毒辣,她知道非如此不能在这个世界上活着。

阅读理解。

     In today's society, a college degree tells little about what you know in comparison to what it tells about

what you can learn. For example, the IT world is constantly changing. Anything you learn today will probably

be useless in a few short years. The point is to learn to learn.

     Blogging (写博客) works exactly the same way. And I believe this to be true regardless of your end goal.

If you're trying to make money , this is very clear. There's always more money to be made. If you're teaching

on a subject, you are constantly looking for new information to share. Even if you're just sharing your words

with others for pleasure, you're continuously improving your writing and storytelling so people don't get bored

of you.

     This is one of the reasons that bloggers burn out. They forget this. They think they have an unlimited

amount of content just waiting to burst from their brain. They get comfortable. Then they start to run out of

juice. Sure, at times it seems that some bloggers just have it. They are experts in their fields and will simply

feed us with invaluable content forever. But this is not true. Pay attention. Even famous bloggers would run

out of content eventually without constant learning.

      The point is easy to see. Don't think you've succeeded. There is no summit. What happens when someone

thinks they've hit the summit? They quickly begin falling down the other side. Always be learning from your

experiences. See what posts work for your readers. Which get the best response? Which are completely

ignored? Which bring in the most Google traffic, or get the most Absence clicks? Don't settle or your blog will

close for ever eventually.
