What can you do when you are unhappy？If you want to let out your anger or pressure by breaking things，you just do．Now a school in Nanjing has built a “stress wall” to help students who feel unhappy due to heavy schoolwork or for other reasons.

The leader of the school said the idea of a stress wall started when footprints were found on some newly painted walls and some school windows were broken.

“These things happen because some students feel lots of pressure from their studies or because they don’t get along well with other students．When under stress，the body gets ready to either run or fight and becomes very nervous．Hitting the wall can help relax the body and take away stress，” he said.

“Tests and homework make me sad，” said a junior girl，“I can’t wait to hit the wall．It will help me a lot with my problems.” However，another girl student who wouldn’t give her name said，” The wall won’t help because it can’t talk，” and she added，” I need to talk to someone when I’m sad.”

【写作内容】

New Holland honeyeaters are experts at sounding the alarm when there's danger, according to new research from biologists at the Australian National University(ANU)and the University of Cambridge.

Study authors, Dr. Jessica McLachlan and Professor Rob Magrath, found honeyeaters can spread the word in the blink of an eye, using a two-stage alarm.

It's particularly effective when they are threatened by fast-moving birds of prey.

＂When a hawk is swooping down, its target has only a second to flee to cover-a split second can make the difference between life and death," Dr. McLachlan said.

＂But animals often signal urgent danger using repeated notes, which makes sure others hear the warning but it takes a long time to deliver."

＂So there's a problem. How to send a lightning-fast message in a long call?”

New Holland honeyeaters solve this problem elegantly. They "front-load" information about urgency into the first note of their alarm call, so other honeyeaters can respond quickly.

The clever honeyeaters follow this up with more notes to reinforce the message and signal how long to remain hidden.

＂They use a long call, with lots of notes, to make sure the message is heard," Professor Magrath said." And the more notes, the more urgent the danger."

＂But they also modify the first note to indicate if it's necessary to take immediate cover. So it's a two-part message that is quick, reliable and informative."

The technique is so effective the authors expect to see other species adopt it.

＂Many other species modify alarm calls as the threat increases, but there is surprisingly little known about how fast they convey the message," Professor Magrath said.

The researchers conducted their study in Canberra's National Botanic Gardens over a period of several years.

＂These birds live in the Gardens and are used to having people around. This helped us to record natural interactions with their predators(捕猎者)，such as sparrow hawks and currawongs, and to video the honeyeaters' responses to different alarm calls," Professor Magrath said.

1.According to Dr. Jessica McLachlan,______

A.speed counts when it comes to honeyeaters' life or death

B.the second-part message in a honeyeater's call is more reliable

C.the message about where to take cover is conveyed very fast

D.the urgency degree relies on the first note in a honeyeater's call

2.What does"they"in Paragraph 12 refer to?

A.alarm calls B.modified notes

C.other species D.clever honeyeaters

3.The researchers' findings are mainly based on

A.the comparison between honeyeaters and other birds

B.the analysis of length of alarm calls made by honeyeaters

C.the record of the honeyeaters' response and signal transmission

D.the observation of birds in Canberra's National Botanic Gardens
