    Many times we tend to use our hands to explain our needs and thoughts.____So you must be cautious when using hand gestures in communication.

    Hand gestures are a way of communicating with others and conveying your feelings. These gestures are most helpful when one is speaking to someone with no language in common. The meanings of hand gestures in different cultures may translate into different things.____Former President George W. Bush had to face a major faux pas(失礼) during a visit to Australia. He tried to signal a peace sign by waving the two-finger or V-sign at the crowd.

    You may think of this as a simple gesture, but he committed a major error.____The meaning of this hand gesture in Australia was asking the crowd to screw themselves, a rude expression used to show you're very angry!____Therefore, it is very important to understand the meanings of gestures before you travel to different countries.

    ____Those considered as good gestures in one country may be termed as offensive gestures in some countries. So, if you are a frequent flier to different countries, improve your communication skills by learning the meaning of hand gestures.

B. Instead of his palm facing outwards, it faced inwards.

C. The great man received warm welcome by the Australians.

悲剧发生后的一些事
材料一:佛山姑娘摆花祭奠
昨日下午1点,一位年轻的佛山姑娘在小悦悦出车祸的地点,摆上一束黄菊花。小悦悦被车碾轧的地方,用黑笔写着一个①,而她被陈阿婆搬到路边的地点,写着一个②。菊花覆盖了②。这位萧姓的姑娘说,“我希望大家知道,佛山不是那么冷漠。”
材料二:“不是人冷漠”
“的确我们平时没有多说话,但是并不代表我们都冷漠。”一家店铺的老板崔先生说。同一天晚上,救治力量有限的黄岐医院就给小悦悦下了病危通知。就在小悦悦的妈妈陷入绝望时,崔先生赶紧给他的朋友打了电话:“你不是认识广州军区总医院的医生吗?我们山东老乡有个孩子被车撞了,急等救命!请一定帮忙!”可是当时医生很忙,说:“现在实在很忙。”崔先生一听,差点冲手机喊了起来:“小孩人命关天!我们半分钟、一分钟也等不了了!”……小悦悦终于在急救车的蜂鸣声中,开往广州军区总医院。
而在离小悦悦血泊最近、记录下了完整的监控录像的新华劳保用品部,同样孩子尚小的老板娘也一直难以忘怀此事。“那天晚上交警和悦悦母亲来我们家问有没有监控,我们就说不知道有没有拍到。……”第二天,小悦悦的父亲搬了3箱饮料,说“感谢她们提供了录像”。“我说真的不用感谢我们,这样的事情很为他们难过,本来能帮的忙就是要帮的,更不能收什么谢礼。”老板娘在店门口百般推辞不过,就先收下来,在日落时分让伙计把谢礼又都送回去了。
“我认为这不单是18个路人的问题,而是这个社会的问题。”佛山市人民政府新闻
办公室副主任说,“现在大家看到了惨剧的后果,都很义愤,说自己一定会出手救助。
但是如果哪一天真的遇到,当你不能预知袖手旁观会造成什么后果,帮忙又会造成什么
后果,每个人都要问自己:我会不会成为路人?”
为了阻止此类悲剧的再发生,对于孩子家长、路人、媒体、政府等,你有什么建设性的建议?请答出至少三条。
