分析 ---我的儿子沉迷于游戏"qq农场偷菜"．
---然而，可以确定的是这个游戏越来越受90后的欢迎．

解答 答案：B．根据选项although尽管； though尽管，放句首时可与although互换，还有"然而，可是"之意，放句中，句末； unless除非，while当…时，尽管，然而（强调前后对比），再结合句意，然而，可以确定的是这个游戏越来越受90后的欢迎，可知此处缺少了一个引导让步状语从句的转折词，故选B．

点评 本题考查让步状语从句的连接词，在充分分析句型再结合语义的基础上便能选出正确答案，同时要注意其他选项的意思，注意although，though，while的区别

12．The long，lonely voyage of the Japanese ghost ship is over．
A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year's tsunami （海啸），sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed to shipping and the coastline on Thursday．
The cutter's guns tore holes in the 164-foot Ryou-Un Maru，and then it began to take on water and lean to one side．In about four hours，the ship disappeared into the sea，said Chief Petty Officer Kip Wadlow．
The ship had no lights or communications system，and its tank was able to carry more than 7，570 liters of diesel fuel．Officials，however，didn't know exactly how much fuel was aboard．
"It's less risky than it would be running into shore or running into other ships，"coast guard spokesman Paul Webb said．
The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it is safer to sink the ship than let the fuel evaporate and pollute the sea environment．
Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of  refrigerators，washing machines，televisions，roofs and fishing nets heading toward North America since last March when a magnitude-9.0 earthquake struck Japan．
As the coast guard was ready to fire on the vessel，a Canadian fishing vessel，the 19-meter Bernice C，claimed the rights to save the ghost ship in international waters．
Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship．A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it．
Then the Canadian boat left，and once it was about 10 kilometers from the Japanese vessel，the Coast Guard began to fire，first with 25 mm shells，then a few hours later with ammunition twice that size．
State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant，to see if Alaska residents，seafood or wild animals could be affected．

56．Which of the following is NOT the reason for sinking the Japanese ship？A
A．It had no lights or communications system．
B．It might be washed up onto the shore．
C．It was a danger to other passing ships．
D．The oil it carried could pollute the sea．

7．Since 1936，many female space explorers have followed Russian astronaut Valentina Tereshkova．Let's look at the missions（任务） of four important female astronauts to find out what astronauts do in space．
In 1983，Sally Ride became the first American women in space．Her team carried out scientific experiments in space and put two communications satellites in space．Satellites make it possible for us to communicate instantly with each other across the world through TV，radio，and telephones．
In 1984，Kathryn Sullivan became the first American women to walk in space．During her mission，she discovered important information about the sun's energy and how it affects the climate in very hot and very cold places on Earth．She also took photographs of Earth and measured air pollution．
In 1992，Mae Jemison became the first African-American in space．During her mission，she did scientific experiments using the weightless atmosphere．In space，there is no gravity，so everything floats!Dr．Jemison's experiments gave important information about the human body to produce better medicines and healthcare．
In 2012，Liu Yang became the first Chinese women in space．She did experiments in space medicine，which look at how astronauts can survive and stay healthy in space．The conditions in space are very hard on the body and space medicine helps astronauts work safely．

55．Who collected important information about air pollution？C
A．Valentina Tereshkova．
B．Sally Ride．
C．Kathryn Sullivan．
D．Mae Jemison
56．What did Dr．Jemison's experiments focus on？A
A．Human body．
B．Space satellites．

57．Liu Yang's mission aimed atB．
A．providing information about environment
B．protecting astronauts'health in space
C．improving communication on Earth
D．testing the weightless atmosphere
58．Which of the following can be the best title for the passage？D
A．Great Walking in Space
B．Conditions in Space
C．Healthcare in Space
D．Women in Space．
