6．John is not a man to count on，and it is very likely that the work ____ by the time he arrives here．（　　）
A．is finishedB．has finished
C．will finishD．will have been finished

分析 John是一個靠不住的人，而且很有可能當他到達這里的時候工作就將要被完成了．

解答 答案：D．
根據(jù)時間狀語by the time he arrives here可知，應該使用將來完成時，又因the work和finish之間為邏輯上的動賓關系，所以用被動語態(tài)；故選D．count on依靠、依賴；it is very likely that…為一常用句型，意為"某事很有可能發(fā)生"．

點評 本題考查將來完成時，表示截止到將來的某個時間點已經(jīng)完成的動作，做題時，要把握句中時間狀語by the time he arrives here這一特點，結合句意，選擇正確的時態(tài)．

2．Passenger pigeons（旅鴿） once flew over much of the United States in unbelievable numbers．Written accounts from the 18th and 19th centuries described flocks（群） so large that they darkened the sky for hours．
It was calculated that when its population reached its highest point，there were more than 3 billion passenger pigeons-a number equal to 24to 40percent of the total bird population in the United States，making it perhaps the most abundant bird in the world．Even as late as 1870when their numbers had already become smaller，a flock believed to be 1mile wide and 320miles （about 515kilometers） long was seen near Cincinnati．
Sadly，the abundance of passenger pigeons may have been their undoing．Where the birds were most abundant，people believed there was an ever-lasting supply and killed them by the thousands．Commercial hunters attracted them to small clearings with grain，waited until pigeons had settled to feed，then threw large nets over them，taking hundreds at a time．The birds were shipped to large cities and sold in restaurants．
By the closing decades of the 19th century，the hardwood forests where passenger pigeons nested had been damaged by Americans'need for wood，which scattered （驅散） the flocks and forced the birds to go farther north，where cold temperatures and spring storms contributed to their decline．Soon the great flocks were gone，never to be seen again．
In 1897，the state of Michigan passed a law prohibiting the killing of passenger pigeons，but by then，no sizable flocks had been seen in the state for 10years．The last confirmed wild pigeon in the United States was shot by a boy in Pike County，Ohio，in 1900．For a time，a few birds survived under human care．The last of them，known affectionately as Martha，died at the Cincinnati Zoological Garden on September 1，1914．

24．In the 18th and early 19th centuries，passenger pigeonsD．
A．were the biggest bird in the world
B．lived mainly in the south of America
C．did great harm to the natural environment
D．were the largest bird population in the US
25．The underlined word"undoing"probably refers to the pigeons'B．
A．escape           B．ruin            C．liberation             D．evolution
26．What was the main reason for people to kill passenger pigeons？C
A．To seek pleasure        B．To save other birds
C．To make money            D．To protect crops．
27．What can we infer about the law passed in Michigan？B
A．It was ignored by the public         B．It was declared too late．
C．It was unfair                        D．It was strict．
