Noaa’s Pacific Marine Environmental Laboratory has developed a warning system that picks up signals of tsunamis directly from the sea-floor.
It is called Dart-the Deep-ocean Assessment and Reporting of Tsunamis. If seismometers(地震仪) detect an earthquake, the Dart buoys(浮标) will determine what is happening to sea levels, and whether a big wave might be on the way. This information is then sent via satellite to a central location which can organize an alarm. Within 50 minutes of the Haiti earthquake, this system was able to issue an alarm to other countries in the Caribbean to say that a small tsunami had been caused to start, and that was unlikely to affect them.
Dr Bernard said, “The first 30 minutes following the earthquake, we have to rely on education.” The critical aspects of this are: do you feel the earthquake; do you see the ocean draw down; and do you hear that loud roar? If so, you should run for higher ground.
“But after the first few minutes, it’s crucial that we have the technology—the measurements to avoid unnecessary evacuation(疏散撤离)and tell people when it is safe to return.” Right now, there are 50 of these Dart buoys all over the globe—four of which are in the Caribbean.
Dr Bernard says that, with 75 to 100 buoys worldwide, this system could provide global tsunami warnings within one hour.
“That’s for everywhere we know that tsunamis have happened. If we wanted to go to half an hour detection, we could probably double or multiply by four times that number,” he said.
“In some countries, including Haiti, there may not be enough resources to support a specific tsunami warning centre for something that happens so infrequently.”
He said that this system was relatively inexpensive to fix and operate.
“To get it down to an hour for everywhere affected would cost $50m initial investment and then 10% of that to maintain it,” he said.
“That’s not a terribly expensive system considering the potential savings of lives.”

Wearing earphones, using complex Net language and constantly text messaging friends, the Gen-90s following the Gen-80s begin to make their world debut (初次登台).
Each generation or age group has its own symbols and lifestyle. Read on and judge for yourselves if you fit the Gen-90s group.
Earphones

Martian language

Self-Portrait
Saying “cheese” to their own digital cameras is usual for this generation. A little bit of narcissism (自恋) never hurts anyone. It helps them reflect a little on their own lives.But be aware of the risks of posting private photos online.

Traditional Chinese gardens are located in North China in such places as Beihai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary(虚构的) line in the middle of the garden on the north-south axis(轴). Other features of imperial gardens are colored-paintings, man-made hills and lakes.
Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. They are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens. Different parts of it are examples of the garden style of the Song, Yuan, Ming and Qing Dynasties.[
The landscape(自然风景) garden contains a number of pleasant natural scenes and some fairy tales. The ancient Chinese used to call the garden landscape “Jing” , which means “scene” in English.

1. Take pictures
One of the great things about taking pictures at an event or party is that it gives you an excuse to get in touch with the person later. Everybody loves seeing pictures of themselves, and it’s very easy after taking a picture to say “If you’d like I can email it to you”. This can be the seed that leads to new connections. The next time you hear about a fun event email your new contacts to let them know about it.
2. Eat alone in public
You might feel self-conscious eating by yourself but it has an important benefit: you are much easier to approach when you are alone. People may be afraid of interrupting you or being rude if you are in a conversation with someone else. Bring a book or newspaper to read (this will make you feel less self-conscious). Plus, having an interesting book with you will give others an excuse to start a conversation if they’ve read it.
3. Join a class, sports team, or club
Yoga, salsa dancing, volleyball, Toastmasters (a public speaking club), a class for work, etc. Take up a new hobby or continue an old one!
These are all great places to meet new people, primarily because you will be forced to see the same people over and over again in the class. You will automatically make friends with them if you have a common interest and are forced to see each other again.
Tips:
* In the beginning, never turn down an invitation from someone, even if it’s something you wouldn’t normally do.
* Email your new friends with fun things to do instead of always asking what their plans are. If they have a better plan you can drop yours and join them. This will help establish you as someone who is contributing value instead of just taking it (people want this in a friend).
* Don’t let little things in life upset you or be a negative person. People don’t want to be around someone like that!

C.invite others to your apartment to eat together |

B.It helps you find out people who share a common interest with you. |
C.It offers an opportunity to meet the same people repeatedly. |
D.It is a good way to meet new people and make friends in a new city. |
A.Try to be outgoing and talkative instead of being shy. |
B.Never turn down an invitation from your friends. |
