6．As sea levels climb，even Washington，D．C．could see more frequent and widespread flooding at high tide．
Strong storms and high winds sometimes bring floods to coastal areas．But cities and towns along the US East Coast are flooding even in calm and sunny weather．Among them is Maryland's capital Annapolis．Tourists there must sometimes walk through water flooding downtown streets surrounding the habor．Sometimes water covers roads in Atlantic City，N．J．Even the yards and basements of coastal homes near New York City sometimes flood．
All are suffering from this trend-----normal high tides surpass（超过） a rising sea level
Sea levels have climbed，on average，about 20centimeters（8inches） over the past 135years．And a sharp increase in tide flooding is one of the more visible impacts affecting many coastal areas，notes William Sweet，an oceanographer．
Sweet and his co-workers recently analyzed data from 45tide gauges（计量表） along the US coasts．These tools record the changing heights of tides as they rise and fall．From these data，Sweet's team calculated the number of"troublesome floods"in various coastal cities．These floods，Sweet explains，typically occur when water level is about 30centimeters（1foot） above the historic level of the highest tides．In June 2014，the team reported finding a growing rise in these flooding events．
In Charleston，S．C，from 1957to 1963，the city experienced troublesome floods an average of 4.6days per year．Bur from 2007to 2013，the occurring rate of troublesome floods jumped five times．Annapolis city was even more serious．From 1957to 1963，troublesome floods were roughly 3.8days per year．From 2007to 2013，the average was 10times higher---39.3days a year．
"Over the next few decades，climate change probably drives sea levels even higher，"Sweet says．"So today's flooding problems promise to become only more widespread and frequent．"

4．The World Health Organization warns that millions of people are dying every year from indoor air pollution．Nearly three billion people are unable to use clean fuels and technologies for cooking，heating and lighting．
These findings show that the use of deadly fuels in inefficient stoves，space heaters or lights is to blame for many of these deaths．
WHO officials say indoor pollution leads to early deaths from stroke，heart and lung disease，childhood pneumonia and lung cancer．Women and girls are the main victims．These diseases can often result from the burning of solid fuels．These fuels include wood，coal，animal waste，crop waste and charcoal．
The United Nations found that more than 95percent of households in sub-Saharan Africa depend on solid fuels for cooking．It says huge populations in India，China and Latin American countries，such as Guatemala and Peru，also are at risk．
Nigel Brace is a professor of Public Health at the University of Liverpool．He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way．There are already multiple technologies available for use in clean fuels．There is really uite an effective and reasonably low-cost alcohol stove that is made by Dometic（a Sweden-based company）that is now being tested out．LPG （liquified petroleum gas）cook is obviously widely available and efforts are under way to make those efficient．Another interesting development is electric induction stoves（电磁炉）．WHO experts note some new，safe and low-cost technologies that could help are already available．In India，you can buy an induction stove for about 8.00．And in Africa you can buy a solar lamp for less than 1.00．
But，this，the agency says，is just a start．It is urging developing countries to use cleaner fuels and increase access to cleaner and more modern cooking and heating appliances．

32．What does the indoor pollution mainly result from？A
A．Poisonous fuels．B．High technology．
C．Space heaters．D．Solar energy．
33．How is Paragraph 3mainly developed？C
A．By showing differences．B．By describing a process．

34．What can we infer from the text？B
A．Indoor pollution results in many diseases．
B．Most of the deaths are in developing countries．
C．The solid fuels are used in more efficient ways．
D．There is no indoor pollution in developed countries．
35．Which of the following is true of different technologies？D
A．LPG cooks are being tested out．

1．The UN weather agency warned on Tuesday there was a good chance of an"El Nino"climate phenomenon in the Pacific Ocean this year，bringing droughts（干旱） and heavy rainfall to the rest of the world The World Meteorological （气象的） Organization （WMO） said its modeling suggested a"fairly large potential for an El Nino，most likely by the end of the second quarter of 2016"．
The El Nino phenomenon occurs every two to seven years，when the trade winds that circulate surface water in the tropical （熟带的） Pacific start to weaken．
WMO pointed out Tuesday that since last December，trade winds had weakened and there had been a significant warming of the waters below the surface in the central Pacific．
"While there is no guarantee this situation will lead to an El Nino event，the longer the trade winds remain weakened，and subsurface temperatures stay significantly warmer than average，the higher chances are，"it said．
Two thirds of climate models predicted that the phenomenon would begin sometime between June and August，with one-fifth suggesting it could start as early as May，and the remaining predicting no El Nino this year，it said．
It is often followed by a return swing of La Nina，which is characterized by unusually cool ocean surface temperatures in the central and eastern tropical Pacific．
"El Nino has an important warming effect on global average temperatures，"Jarraud cautioned，stressing that combined with warming from greenhouse gases such events had"the potential to cause a sharp rise in global average temperature"．
33．It can be inferred from the first two paragraphs thatB-'
A．a weather agency warned an"El Nino"would appear on Tuesday
B．WMO showed an El Nino would probably happen by June in 2016
C．an El Nino would bring heavy rainfall to the Pacific Ocean
D．The phenomenon of El Nino happens every seven years
34．What does the underlined phrase"this situation"in Paragraph 4refer to？A
A．Cool ocean surface temperatures in the central and eastern tropical Pacific．
B．A significant warming of the waters below the surface in the central Pacific．
C．Trade winds that circulate surface water in the Pacific．
D．Heavy rainfall in different areas all over the world．
35．According to the text，what might be the percentage of no"El Nino"this year？D
A.13%． B.20%． C.67%． D.87%．
