Psychologists take opposing views of how external rewards,
from warm praise to cold cash, affect motivation and creativity.
Behaviorists, who study the relation between actions and their
consequences, argue that rewards cannot improve performance ___1___
at work and school. Cognitive resear-chers, who study various
aspects of mental life, maintain that rewards often destroy
creativity by encouraging independence on approval and gifts ___2___
from others.
The later view has gained many supporters, especially ___3___
among educators. But the careful use of small monetary rewards
speak creativity in grade-school children, suggesting that properly ___4___
presented inducements（刺激）indeed aid inventiveness,
according to a study in the June Journal of Personality and Social
Psychology. " If kids know they are working for a reward and can
focus on a relative challenging task, they show the most creativity." ___5___
says Robert Eisenberger of the University of Delacare in Newark.
"But it is easy to kill creativity through giving rewards for ___6___
poor performance or creating too much anticipation of rewards." ___7___
"A teacher who continually draws attention to rewards or who
hands out high grades for ordinary achievement ends up uninspired ___8___

In earlier grades, the use of so-called token economics, in
that students handle challenging problems and receive ___9___
performance-based points toward valued rewards, show promise ___10___

1. of -> /
本行中only have oneselve to blame为习惯用法，意为“只能怪自己”。由本行后半部分的because of 后是一个完整的句子可确定because of 中的of 应删掉，因为because of相当于一介词，后面只能接名词或动名词。而because后接的应该是句子。

2. is -> are
That引导定语从句，修饰clothes，因为此处clothes为复数，所以从句的谓语动词也要用复数形式。

3. taking -> taken
本句前半部分是由because引导的原因状语从句，主句为逗号后的they are ….designers；take advantage of sb意为“利用某人，占某人便宜”，根据by the designers 可知，此处是在讲女性被服装设计师所利用。

4. announced -> announcing
capable of后standing ….and …为其并列的宾语，故将announced 改为announcing

5. anything -> nothing
由该句中creation of waste可判断，本句在表达否定或消极意见，而anything本身并没有否定意义。Nothing more than和no more than的意思和用法相近，意为“不过，仅仅”，故将anything改为nothing。

6. cannot前加who 或that
cannot afford和waste均为动词，中间没有连词及waste所在行没有错误，由此可确定waste是该句的谓语，那么cannot afford就是定语从句的谓语。定语从句中，当现行词为人时，一般用who或that来引导定语从句。

7. usually -> rarely
contribute…for…意为“为…贡献出…”，后接贡献的对象，类似的用法还有contribute…to / towards…；usually“常常，经常”，与上句NO one…for society和下句they are only interested in…look right在语意上矛盾，故将usually改为rarely。

8. which -> that
Tthe fact是抽象名词，后常接同位语从句，which不能引导同位语从句，只有that才能。

9. picked -> picking
上一行中的or使其前后形成并列，故前后动词形式要保持一致（与shaking保持一致）。

10. reflects -> reflect
本句为助动词do置于句首的一半疑问句，谓语应为动词原形；one wonders在此作插入语，是修饰成分，不与reflect形成并列或转折关系
