19．According to experts，China needs to ____ its one-child family planning policy to fight against a worsening gender（性别） imbalance and an aging population．（　　）

8．Chicago is considering firm measures to prevent the Asian carp，a giant fish native to the Far East，from coming into North America's Great Lakes in large numbers．Such a move could cost up to$18bn，a heavy economic burden to the city．
This species，more than a metre in length，was originally introduced to southern US states three decades ago to control weeds in sewage（污水）treatment plants．But they escaped into the Mississippi River and increased in number quickly，making their way north towards the Great Lakes and threatening the native fish species along the way．
"Dozens of them will often leap out of the water as boats approach．''Michael Beecham，a local environmental expert，described how frightening the scene was．"I've gone down the river and seen these fish jump up and hit me in the face．It is a big problem for our native species，"he said．
A meeting has been organized to find a technological solution to the carp problem，one of which involves blocking parts of Chicago's canal system．Listening at the meeting was John Goss，who was worried about the effect that having barriers in the canal system would have on industry．"It would certainly increase the cost of transportation，"he told．"It is currently very cheap and efficient to bring materials and finished goods down the Chicago ship canal．"
Another cheaper option is to eat the fish out of existence．Dirk Fucik is selling carp burger（鲤鱼汉堡包）at his fish shop not far from downtown Chicago．He thinks the carps are a great resource．"To catch it and throw it away is a waste，"he says．"Eating them helps solve the problem and also provides jobs．"But the idea has not yet caught on．So far，he is the only person in Chicago selling carp burgers．

11．A new study links heavy air pollution from coal burning to shorter lives in northern China．Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air．
China itself made the comparison possible：for decades，a now-discontinued government policy provided free coal for heating，but only in the colder north．Researchers found significant differences in both particulate pollution of the air and life expectancy in the two regions．
While previous studies have found that pollution affects human health，"the deeper and
ultimately more important question is the impact on life expectancy，"said one of the researchers，Michael Greenstone，a professor of environmental economics at Massachusetts Institute of一Technology．
"This study provides a unique setting to answer the life expectancy question because the
（heating） policy dramatically changes pollution concentrations（含量），Greenstone said in an email．"Further，due to the low rates of migration in China in this period，we can know people's exposure over long time periods，"he said．
The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Riv饥which divides China into north and south．It was in effect for much of the 1950-198，0 period of central planning，and，though discontinued after 1980，it has left a legacy（遗留Pl in the north of heavy coal burning，which releases particulate pollutants into the air that can harm human health．Researchers found no other government policies that treated China's north differently from the south．
The researchers collected data for 90cities，from 1981to 2000，on the annual daily average
concentration of total suspended（悬浮的）particulates．In China，those are considered to be particulates that are 100micrometers or less in diameter，sent out from sources including power stations，construction sites and vehicles．Among them，PM2.5is of especially great health concern because it can go deep into the lungs．
The researchers estimated the impact on life expectancies using death data from 1991-2000．They found that in the north，the concentration of particulates was 184micrograms per cubic meter一or 55percent higher than in the south，and life expectancies were 5.5years lower on average across all age ranges．

62．The main idea of this passage is thatA．
A．research in China finds air pollution shortened life expectancy
B．the government provided free coal for heating in North China
C．coal burning causes bad air quality across China
D．a new study finds different particulates in South China
63．According to Greenstone，Cgreatly contributed to the high pollution concentrations in North China．
A．power stations
B．construction sites
C．the free heating policy
D．gases from vehicles
64．It is implied in the passage thatB•
A．coal is no longer used for heating in North China
B．air quality was comparatively better in South China
C．southerners burned coals for heating in the 1980s
D．people preferred to live in South China after 1980
65．The underlined word"particulates"most probably meansC．
A．dirty clouds
B．particular smoke
C．harmful dust
D．dangerous bacteria．

1．The shocking collapse of one of the West Coast's biggest wild salmon runs has prompted even cash-trapped fishermen to call for an unprecedented （空前的） shutdown of salmon fishing off the coasts of California and Oregon．
The Sacramento River salmon run is usually one of the most productive on the Pacific Coast，providing the bulk of the salmon caught by sport and commercial trollers off California and Oregon．
But only about 90，000adult salmon returned to the Central Valley last fall--the second lowest number on record and well below the number needed to maintain a healthy fishery．That number is projected to fall to a record low of58.000this year．
The council，which regulates Pacific Coast fisheries，will choose between three management options：a total ban on salmon fishing off the coast of California and Oregon；extremely limited fishing in select areas；or catch-and-release fishing for scientific research．
For consumers，it will be hard to find any Chinook，also known as king salmon．which are prized by trollers，seafood critics and upscale restaurants．There should still be abundant supplies of farm-raised salmon．but prices could be higher．
Biologists and others are trying to figure out what caused the salmon collapse so they can make sure California's Chinook populations rebound．
There are many potential factors，because wild salmon are born in streams and rivers，migrate to the ocean when they're juveniles and spend two to four years there before returning to spawn（产卵）in the areas where they were born． In between they have to navigate the often dangerous waters of the Sacramento Delta and San Francisco Bay．
The council has asked state and federal scientists to research possible causes，including water diversions，habitat destruction，dam operations，agricultural pollution，and ocean conditions．Many scientists point out that unusual weather patterns disrupted the marine food chain along the Pacific Coast in 2005，when thousands of seabirds washed up dead or starving because they couldn't find enough to eat．
Researchers believe those poor ocean conditions also devastated the juvenile salmon that would have returned to the Central Valley last year．Young Chinook couldn't find the tiny shrimp and fish they depend onto survive．

36．The underlined word"troller"in the 2nd paragraph meansA．
A．fisherman B．merchant C．seafood dealer D．organizer
37．Which of the following statements is true about the passage？A

B．The salmon migrates to the ocean when they grow up．
C．The farm-raised salmon is not as delicious and nutrients as the wild salmon．
D．Salmon fishing off the coasts of California and Oregon is strictly forbidden．
38．The underlined sentence"In between they have to navigate the often dangerous waters of the Sacramento Delta and San Francisco Bay．"in Para 7indicates thatC．
A．a11the salmon with their young are able to come back to their birthplace．
B．Sacramento Delta and San Francisco Bay are off the coast of California．
C the salmon has to be strong enough to survive the rapid flowing waters．
D．the salmon has to swim across the Sacramento Delta and San Francisco Bay once in their life．
39．The possible causes of the salmon decrease mentioned do NOT includeC．
A．abnormal weather patterns broke me marine food chain along the Pacific Coast
B．bad ocean condition prevented the salmon from returning to their birthplace
C．many salmons are eaten in the ocean before they are capable of returning
D．the dam operation may change the salmons'living environment in the river
40．The passage is mainly about--．B
A．the agricultural pollution soils the coast，
B．the declining number of salmon could bring fishing ban
C．the disrupted food chain in the Pacific Coast
D．the fishermen could make little profit of salmon．
