分析 曾在那所廢棄的房子里住了十年的那對老夫妻現(xiàn)在已經(jīng)被安頓在養(yǎng)老院了.

解答 答案:A
根據(jù)句意可知,由于那對老夫妻現(xiàn)在已經(jīng)被安頓在養(yǎng)老院了,不在那所廢棄的房子里住了,因此"住在廢棄的房子里"是發(fā)生在過去的動作,句中的時間狀語now對應(yīng)的是過去;故應(yīng)使用一般過去時;B.現(xiàn)在完成時,表示發(fā)生在過去并持續(xù)到了現(xiàn)在的動作;C.過去完成時,表示發(fā)生在過去某時間之前的動作;D.現(xiàn)在完成進行時,表示從過去某時開始一直持續(xù)到現(xiàn)在的動作,并且還將持續(xù)下去;B.C.D都不符合句意;故選A

點評 本題考查了一般過去時的用法.在做類似的時態(tài)題,首先應(yīng)根據(jù)句意提示或句中的時間狀語,正確判斷出動作發(fā)生的時間;其次應(yīng)熟練掌握各時態(tài)所表達的意義用法及它們相互之間的用法區(qū)別.

4.Europe on Thursday launched the first satellite of its Copernicus Earth observation project that will supply valuable images in the event of natural disasters or even a plane crash.
     The Sentinel-la satellite,which was sent into Earth's orbit from Europe's spaceport in French Guiana9 will be used to monitor sea ice,oil spills and land use and to respond to emergencies such as floods and earthquakes.
The Copernicus proiect,for which the European Union and the-European Space Agency (ESA) have committed funding of around 8.4 billion euros (_$_11.5 billion) until 2020,is described by the _ESA as the most ambitious earth observation program  to date.
"The big step forward is that we can now cover every place on Earth every three to six days,"Volker Liebig,director of ESA's Earth Observation program,said ahead of the launch."If you want to use images for disaster management support or to find a plane,then you want the images to be as fresh as possible."But he cautioned you would first need to know roughly where a plane had crashed,which is not the case with the missing Malaysian Airlines jet.
    Copernicus also offers new business opportunities.Images can be downloaded free of charge,meaning companies can then use them to help deliver data to farmers on soil conditions or pest infestation,help oil companies decide where to drill new wells or make it easier for insurers to assess the risk of costly floods and fires.
     Sentinel-la,which will operate with a second satellite,Sentinel-1b,to be launched next year,has high-tech instrurnents that will allow it to record radar images of Earth's surface,even when the skies are cloudy or dark.As part of the Copernicus program,there will be 17 launches over the next decade.
61.For what purpose was the Sentinel-la satellite sent up into space?A
A.To improve observation of the earth.
B.To search for some missing planes.
C.To download free valuable images.
D.To predict floods and earthquakes.
62.What do we know about Copernicus Earth observation project,C?
A.It can cover every place on Earth at the same time.
B.It makes a profit by offering downloaded images.
C.It is financed by the European Union and ESA.
D:It has put two satellites into Earth's orbit successfully.
63.According to Volker Liebig,the Sentine-la satelliteB.
A.can locate the missing Malaysian Airlines jet
B.has advanced but limited functions
C.may cause some safety problems
D.doesn't work on cloudy days or at night
64.How does the Copernicus project benefit farmers?A
A.By supplying data on soil conditions.
B.By calculating the loss of costly floods.
C.By drilling oil wells in proper places.
D.By controlling the risk of potential fires.
65.What does the last paragraph mainly tell us about the Sentinel-1a satellite?D
A.Its operation
B.Its appearance
C.Its instruments
D.Its future.
