9．If you saw another kid ride her bike too fast around a corner and fall down，you might ride your bike more slowly on that turn．Yes，we humans are very sensitive to others'mistakes．And the same is true for other animals．Animals mess up all the time．They might eat poisonous leaves，fall off a tree or let their prey（猎物） slip away．By watching others fail，an animal can avoid making the same mistakes，thus improving its chance of survival．
Scientists suspected that one part of the brain helps animals process information about others'errors．Cells in that part appear to become more active when a person sees someone else making a mistake．But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors．
To investigate the brain's response to errors in more detail，the researchers taught a game to two macaques，a type of monkey．One monkey could press a yellow or green button while the other watched．If the first monkey pressed the right button，the team gave both animals a treat．Every couple of rounds，the two monkeys switched roles．Meanwhile，the scientists monitored individual cells in the animal's brains．
When the first monkey messed up the game by pressing the wrong button，a group of cells in the second monkey's brain fired．But if the second monkey also made the wrong choice during its turn，some of the cells in that group didn't respond．Those unresponsive cells reacted specifically to mistakes made by others，not to the monkey's own mistakes．
Scientists believe other parts of the brain also might help people process information about another's errors．"You start to think about this other person and see things from his angle．"Ellen de Bruijn told Science News．She studies the brain at the University of Leiden in the Netherlands．

C．is being lost because of humans
D．ensures that they will never fail
32．The underlined word"detecting"in Paragraph 2probably means"D"．
A．correcting
B．making
C．drawing
D．sensing
33．From the game the scientists taught to two macaques，we can see．C
A．animals can avoid the same mistakes
B．which part of the brain is more active
C．how the brain responds to mistakes
D．how the brain processes information
34．In the experiment mentioned，those unresponsive cells are only sensitive toA．
A．others'mistakes
B．the same buttons
C．one's own mistakes
D．the monkey's brain
35．What's the main idea of the passage？A
A．Animals can learn from mistakes like human beings．
B．An interesting experiment by scientists surprised us．
C．Monkeys can avoid making mistakes by learning from us．
D．The brain cells are always sensitive to others'information．

11．如果天气允许的话，我们将在树林里野餐．（permit）Weather permitting，weare going to have a picnic in the woods/forest．
If weather permits，weare going to have a picnic in the woods/forest．．

8．Using Garbage as a Fuel
Garbage can be a good fuel to use．The things in garbage do not look （53）like coal，petroleum，or natural gas，but they are chemically similar to these fossil fuels．As we use up our fossil fuel supplies，we might be able to use garbage as （54）an energy source．Burning garbage（55）is（ be） not a new idea．Some cities in Europe and the United States （56）have been burning （burn） garbage for years．The heat that is produced by burning garbage is used to boil water．The steam that is produced is used to make electricity or to heat nearby （57）buildings（ build）．In Paris，France，some power plants burn almost 2million metric tons of the city's garbage each year．The amount of energy （58）produced（produce） is about the same as would be produced by burning almost a half million barrels of oil!
But there are problems in using garbage as a fuel．Garbage that burns（59）easily（easy），such as food and paper，must be separated from metals，glass，and other materials（60）that/which do not．Another problem is that burning garbage can pollute the air．Our fossil fuel supplies are （61）limited （limit）．Burning garbage might be one kind of energy source that we can use to help meet our energy needs．This method could also reduce the amount of garbage（62）piling （pile） up on the earth．
