A．as ifB．even thoughC．so thatD．in case

分析 在進入洞穴之前，要多準(zhǔn)備幾個手電以免其中的一個沒電了．

6．About ten years ago，a young and very successful businessman named Josh was traveling down a Chicago neighborhood street．He was going a bit too fast in his shiny，black，12cylinder Jaguar XKE，which was only two months old．
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something．As his car passed，no child came out，but a brick sailed out and-WHUMP!-it hit the Jaguar's shiny black side door!SCREECH…!!!!Immediately Josh stopped the car，jumped out，seized the kid and pushed him up against a parked car．He shouted at the kid，"What was that all about and who are you？Just what the heck are you doing？!""That's my new Jaguar，that brick you threw is gonna cost you a lot of money．Why did you throw it？"
"Please，mister，please…I'm sorry!I didn't know what else to do!"begged the youngster．"I threw the brick because no one else would stop!"tears were streaming down the boy's face as he pointed around the parked car．"It's my brother，mister，"he said．"He rolled off the curb （路沿） and fell out of his wheelchair and I can't lift him up．"Sobbing，the boy asked the businessman，"Would you please help me get him back into his wheelchair？He's hurt and he's too heavy for me．"
Moved by the words，the young businessman lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts，checking to see that everything was going to be OK．He then watched the younger brother push him down the sidewalk toward their home．
It was a long walk back to the black，shining，12cylinder Jaguar XKE--a long and slow walk．Josh never did fix the side door of his Jaguar．He kept the dent （凹痕） to remind him not to go through life so fast that someone has to throw a brick at him to get his attention．Feel for the bricks of life coming you．

1．It is early morning in northern Gaza．The streets are filled with children on their way to school．Most carry backpacks almost as big as themselves．All are dressed in clean and tidy uniforms．It is quite an incongruoussight as they walk past piles of destroyed buildings from Israel's military operation earlier this year．
In the Elyen family home，nine-year-old Huda is nervous．Her mother is still preparing sandwiches．Huda is worried she will be late for school．
As bags are packed and hair curled，there is not much wriggle （身體扭動） room for the three school-aged children here．The Elyens live in a weak，one-bedroom shelter．
Their house was destroyed and one of their cousins killed in an Israeli airstrike in January．Amer，their father，is worried about the winter．He tells me he cannot afford a proper roof．
He has been out of work for three years，ever since Israel forced heavy restrictions （限制） on border crossings into the Gaza Strip （加沙地帶），damaging the already weak local economy．
Amer says he hopes his children will finish their schooling，regardless of poverty or violence．
He had to leave school as a young boy to help support his brothers and sisters．He firmly believes that education can open doors to a better life．
But many of Gaza's schoolchildren are less optimistic．They know that no matter how educated they are，opportunities are scarce．Unemployment is unavoidable．
Escaping Gaza for a better life elsewhere is almost impossible，as neighboring Israel and Egypt keep their crossings with Gaza pretty much sealed shut．
Schooling is also repeatedly interrupted by conflict．This is sometimes due to violence but mainly because of military action by Israel．Israel says this is in response to rocket by Gaza militants （激進分子），aimed at Israeli citizens．
55．The underlined word"incongruous"in the first paragraph probably meansD．
A．not famous                             
B．not familiar 
C．not beautiful                           
D．lacking in harmony
56．From the passage，we can infer the following EXCEPTD．．
A．Elyen's family is very poor．
B．there are five people in Elyen's family in total                         
C．it is very difficult to find a job in northern Gaza
D．people in Gaza can make a living by escaping Gaza
57．According to the passage，which of the following about Amer is true？A
A．He supports his children to go to school．
B．He will manage to get a proper roof．
C．He had a good education when he was young．
D．He thinks that education is of little importance．
58．The main idea of the passage should be （that）B．
