2.Friday,December 30,2011 has been cut for the tiny South Pacific island nation,Samoa as it moved its time zone 24 hours ahead to catch up with Asia,New Zealand and Australia. On New Year's Eve,Samoa will Slave jumped to the west of the international dateline,which runs through the Pacific Ocean and broadly follows the 180 degree line of longitude (经线).
Its Prime Minister said it would make it easier for Samoa to trade with their key partners."No longer shall we have people ringing us up on Monday from New Zealand and Australia thinking it is Monday when we are closing our eyes and praying at churches.And in the same way,on our Fridays when we ring up and already our contacts are holidaying on their Saturdays,"he told Radio New Zealand on Friday.
To help win public support,the government declared employers must still pay workers for the missing Friday,although banks will not be allowed to charge interest for the lost day.
Countries are free to choose whether the dateline passes to the east or west,and Samoa's decision means all new maps will need to change.But some tourism operators are worried Samoa will lose business by losing its position as the last place on earth to see the sunset each day,although it is now one of the first places to see in each new day.
Samoa,a country of about 180,000 people,used to be in the same time zone as New Zealand and Australia,but went back a day in 1892,celebrating July 4 twice and aligning itself with the United States.The date change is not the first major change in Samoa in recent years.In 2009,the country switched to driving on the left hand side of the road from the right hand side,in line with New Zealand and Australia.

1.Whether you live in Seattle or the Sahara desert,the time has come to invest in a good raincoat or umbrella,a new study suggests.
As global temperatures continue to rise,more"extreme rain"events---intense,cats-and-dogs downpour---can be expected,said the study,published Monday in the journal Nature Climate Change.And that,scientists said,means an increased flood risk,particularly for the world's driest areas.The study challenges the idea that global warming is causing dry areas to become drier and wet areas wetter.
"In both wet and dry regions,we see these great increases in heavy precipitation (冰雹),"lead author Markus Donat,a climate scientist at the University of New South Wales,told Nature.
Donat and his team collected data from 1951to 2010on extreme precipitation events from 11,000weather stations around the world,Nature reported.In that time,the number of days with"extreme precipitation"increased 1percent to 2percent per decade.
"We found a strong relationship between global warming and an increase in rainfall,particularly in areas outside of the tropics,"Donat said in a statement.
"Importantly,this research suggests we will see these extreme rainfall events increases at regional levels in dry areas,not just as an average across the globe,"Donat added.
Peter Stott,a senior climate scientist at Met Office,told Climate Central that the study's findings are important,because more violent rainfall and flooding will"challenge our capability to adapt to a rapidly changing climate."
As Nature reported,the research aligns (结盟) with a 2015study that found global warming has led to a sharp increase in record-breaking precipitation events.Donat told Nature that his study should come as a warning to world governments.

1.Which of the following is one of the study's findings?B
A.Global warming is causing dry areas to become drier and wet areas wetter.
B.Extreme rain events can be expected at regional levels in dry areas.
C.Extreme rainfall events increase at regional levels in wet areas.
D.Rainfall increases particularly in the tropics areas.
2.Why does Scott think the findings are important?C
A.The research aligns with a 2015study.
B.They are about extreme precipitation events.
C.They remind us to adjust to rapid climate changes.
D.The study involves many famous climate scientists.
3.The purpose of the study is toD.
A.encourage investors to start business in Seattle or the Sahara desert
B.persuade people to take a raincoat or an umbrella with them
C.challenge the previous findings of research on climate
D.warn world governments to focus on global warming.
