2.--There'ssomeone knocking on the door.Who _____it be?
-It must be Mary.She promised to be here at 8:00.(  )
A.mustB.needC.shallD.can

分析 ---有人在敲门.会是谁呢?
---一定是玛丽.她答应8:00到这里的.

解答 答案:D
根据本句的语境"There'ssomeone knocking on the door.有人在敲门"以及答语"It must be Mary…一定是玛丽…"得知,"Who _____it be?"应该是表示推测.A must 表示比较肯定的推测,一定,只用于肯定句; B 需要  C shall 在疑问句中表示征求对方意见,主要用于第一、三人称,有"…好吗?","要不要"D can 可能,一般用于疑问句或否定句.故选D

点评 情态动词表示推测的用法是考查的重点,所以要注意总结表示推测的情态动词的用法及区别.

2.It was six or seyen years ago that I first witnessed a ginger cat break into my house.His name was Samson and,while"cat''was one description you might have applied to him,another more accurate one was"ginger beach ball that just happened to have a cat's head on top".He belonged to Ruby,a lady in her 80s living across the road.Soon the two of us became friends:me allowing him to steal my cat's biscuits,him allowing me to stroke him while staring up at me in a relaxed way.If he had been able to speak,the maj ority of his sentences would have ended in the word"dude"(伙计).
    When Ruby died in 2009,a friend who lived several miles away adopted Samson.A strict diet foilowed,which,left Samson looking less like a beach ball and more like a smaller cat wearing a baggy ginger sweater.While he had been around,I had complained a little about mv extra cat food bills and feared for my armchairs and sofa which were often violently scratched.but in the year or two after he'd gone I missed him a lot.
    In the past two and a half years,I've been visited by a succession of ginger cats,all of whom have been lovable,and all of whom have proved costly in either an emotional or financial sense.
    I'm moving out soon and facing up to the fact that I might never see them again.I've told the buver of my house about the essential information of it,especially the visiting cats.The chances are that one day if a cat,whether it is from one of the neighbours or just a stray one,turns up by his doorway,he can at least feed it.

11."Well,what did I say?Buck's a real fighter,all right,"said Francois the next morning when he discovered that Spitz had disappeared and that Buck was covered in blood.
"Spitz fought like a wolf,"said Perrault,as he looked at the bites all over Buck.
"And Buck fought like ten wolves,"answered Francois."And we'll travel faster now.No more Spitz,no more trouble."
Francois started to harness the dogs.He needed a new lead-dog,and decided that Solleks was the best dog that he had.But Buck jumped at Solleks and took his place.
"Look at Buck!"said Francois,laughing."He's killed Spitz,and now he wants to be lead-dog.Go away,Buck!"
He pulled Buck away and tried to harness Solleks again.Solleks was unhappy too.He was frightened of Buck,and when Francois turned his back,Buck took Solleks'place again.Now Francois was angry.
"I'll show you!"he cried,and went to get a heavy club from the sledge.
Buck remembered the man in the red coat,and moved away.This time,when Solleks was harnessed as lead-dog,Buck did not try to move in.He kept a few meters away and circled around Francois carefully.But when Francois called him to his old place in front of Dave,Buck refused.He had won his fight with Spitz and he wanted to be lead-dog.
For an hour the two men tried to harness him.Buck did not run away,but he did not let them catch him.Finally,Francois sat down,and Perrault looked at his watch.It was getting late.The two men looked at one another and smiled.Francois walked up to Solleks,took off his harness,led him back and harnessed him in his old place.Then he called Buck.All the other dogs were harnessed and the only empty place was now the one at the front.But Buck did not move.
"Put down the club,"said Perrault.
Francois dropped the club,and immediately Buck came up to the front of the team.Francois harnessed him,and in a minute the sledge was moving.
Buck was an excellent leader.He moved and thought quickly and led the other dogs well.A new leader made no difference to Dave and Solleks; they continued to pull hard.But the other dogs had had an easy life when Spitz was leading.They were surprised when Buck made them work hard and punished them for their mistakes.Pike,the second dog,was usually lazy;but by the end of the first day he was pulling harder than he had ever pulled in his life.The first night in camp Buck fought Joe,another difficult dog,and after that there were no more problems with him.The team started to pull together,and to move faster and faster.
"I've never seen a dog like Buck!"cried Francois,"Never!He's worth a thousand dollars.What do you think,Perrault?"
Perrault agreed.They were moving quickly,and covering more ground every day.The snow was good and hard,and no new snow fell.The temperature dropped to 45°C below zero,and didn't change.
This time there was more ice on the Thirty Mile River,and they crossed in a day.Some days they ran a hundred kilometers,or even more.They reached Skagway in fourteen days; the fastest time ever.

55.The writer mentioned"the man in the red coat"in the passage to show thatA.

B.Buck remembered Francois was the man in the red coat.

56.Why did Buck fight Joe the first night in camp?D
A.He wanted to get rid of Joe.
B.He wanted to make some trouble.
C.He was interested in fighting with others.
D.He wanted to teach Joe a lesson.

A.Dave stood in the second position in the team.
B.Joe was always quite lazy in the team.
