7.I thought our friendship was finished         Jenny apologized first and I forgave her right then.(  )
A.whenB.untilC.whileD.unless

分析 我以为我们的友谊结束了,直到简妮先向我道歉,而且在那时我原谅了她.

解答 答案B.
when"在…时候",引导时间状语从句.until"直到",引导时间状语从句.while表示"当…的时候",引导时间状语从句;意为"尽管、虽然",引导让步状语从句;意为"而、但是",引导比较状语从句.unless"除非,如果不",在意义上相当于if…not,因此在有些场合中unless与if…not可互换使用,引导条件状语从句.分析可知前后两句话之间是逻辑上的"时间"关系,再结合句子所表达的意思可知答案选B.

点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.

9.How the Grand Canyon (大峡谷) was created remains one of the geology's greatest mysteries.Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years.But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.
Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon.Such a flood is usually released when a natural or man-made dam (堤坝) bursts.
Robert Webb,a research geologist,says natural dams seem to have formed and broken across the Colorado River several times during the last million years.The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river.The lava hardened into hard rocks and blocked the river,causing it to back up and form a lake.Each time the lake grew so huge that it broke the rock dam,releasing a flash flood that furthered the down-cutting process and deepened the canyon.
Down-cutting is not just an earthly event.Satellite photos sent back from Mars suggest that the process has happened there,too,say many other researchers.
The photos,taken by the Mars Global Surveyor,indicate that an enormous lake existed on Mars 3.5billion years ago.The lake spilled into a large nearby hole.One edge of the hole broke,releasing a flash flood that quickly carved out a grand canyon.
The existence of down-cutting on Mars is just one more piece of evidence that the cold,dry planet was once warm and wet.

24.In the past,deep canyons were believed to have formedB.
A.as a result of a sudden break of volcanoe
B.due to river flows over millions of years
C.owing to the burst of artificial dams
D.thanks to our ancestors'creative work
25.According to the passage,which of the following statements is TURE?B
A.Several volcanoes broke out on Mars directly creating grand canyons.
B.Several great lakes existed on the upper parts of the Colorado River.
C.People built high dams on the upper parts of the Colorado River.
D.The Colorado River crossed the Grand Canyon to form down-cutting.
26.From the last three paragraphs we learn thatD.
A.there are great lakes on Mars                         
B.there are active volcanoes on Mars
C.there might be cities on Mars                        
D.there might be life on Mars
27.The passage can be titled asD.
A.Lakes on Earth and Mars                                    
B.The Cause of Lake Formation
C.The Force of Dam Breaking                                
D.Canyons-Results of Flood Cutting.
