19．Unfortunately，although Van Gogh  committedhis whole being to painting，he received  little reward for his effort．

分析 遺憾的是，盡管梵•高全身心地投入繪畫，他所得到的回報卻微乎其微．

解答 答案是committed．考查詞組 commit sb．/oneself to sth．/doing sth．/sb．承諾（做）某事；致力于（做）某事．由主句received可知句子是一般過去時態(tài)，所以commit用過去式committed．故答案是committed．

點評 本題考查單詞填空．首先要根據(jù)語境明確句意，然后再根據(jù)相關(guān)語法決定正確答案．

9．I travel a lot，and I find out different"styles"of directions every time I ask"How can I get to the post office？"
Foreign tourists are often confused in Japan because most streets there don't have names； in Japan，people use landmarks in their directions instead of street names．For example，the Japanese will say to travelers，"Go straight down to the corner．Turn left at the big hotel and go past a fruit market．The post office is across from the bus stop．"
In the countryside of the American Midwest，there are not usually many landmarks．There are no mountains，so the land is very flat； in many places there are no towns or buildings within miles．Instead of landmarks，people will tell you directions and distances．In Kansas or Iowa，for example，people will say，"Go north two miles．Turn east，and then go another mile．"
People in Los Angeles，California，have no idea of distance on the map； they measure distance in time，not miles．"How far away is the post office？"you ask．"Oh，"they answer，"it's about five minutes from here．"You say，"Yes，but how many miles away is it？"They don't know．
It's true that a person doesn't know the answer to your question sometimes．What happens in such a situation？A New Yorker might say，‘Sorry，I have no idea．"But in Yucatan，Mexico，no one answers"I don't know．"People in Yucatan believe that"I don't know"is impolite．They usually give an answer，often a wrong one．A tourist can get very，very lost in Yucatan!

21．When a tourist asks the Japanese the way to a certain place they usuallyB．
A．describe the place carefully
B．refer to recognizable buildings and places
C．show him a map of the place
D．tell him the names of the streets
22．Which is the place where people measure distance in time？C
A．New York．         B．Kansas．
C．Los Angeles．      D．Iowa．
23．People in Yucatan may give a tourist a wrong answerD．
A．in order to save time       B．a(chǎn)s a test
C．for fun                     D．so as to be polite
24．What can we infer from the text？C
A．It's useful for travelers to know how to ask the way properly．
B．People have similar understandings of politeness．
C．It's important for travelers to understand cultural differences．
D．New Yorkers are generally friendly to visitors．

 My parents and I went to the park last Sunday．There were lots of visitors stand in front of the ticket window．We waited a long time and buy three tickets．In the Tiger Mountain of the park，I was too eager to see the fierce frightened animals that I quickened my steps through the crowd．Unfortunate，I got separated from my parents．I had hard time looking for them，and I had no luck．Wandering in the park，I felt alone without any companions．Worse still，I had no money，so I had to walk to home，covering as much as 5 kilometer．

14．The kids in a village in Ethiopia wear dirty，ragged clothes．They sleep beside cows and sheep in huts made of sticks and mud．They have no school．Yet they all can chant the English alphabet，and some can make words．
The key to their success：20 tablet computers（平板電腦） dropped off in their Ethiopian village in February by a U．S．group called One Laptop Per Child．
The goal is to find out whether kids using today's new technology can teach themselves to read in places where there are no schools or teachers．The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed．"What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten，"said Matt Keller，who runs the Ethiopia program．
The fastest learner-and the first to turn on one of the tablets-is 8-year-old Kelbesa Negusse．The device's camera was disabled to save memory，yet within weeks Kelbesa had figured out its workings and made the camera work．He called himself a lion，a marker of accomplishment in Ethiopia．
With his tablet，Kelbasa rearranged the letters HSROE into one of the many English animal names he knows．Then he spelled words on his own．"Seven months ago he didn't know any English．That's unbelievable，"said Keller．
The project aims to get kids to a stage called"deep reading，"where they can read to learn．It won't be in Amharic，Ethiopia's first language，but in English，which is widely seen as the ticket to higher paying jobs．
19．How does the Ethiopia program benefit the kids in the village？B
A．It trains teachers for them．
B．It helps their self-study．
C．It raises their living standards．
D．It provides funds for building schools．
20．What can we infer from Keller's words in Paragraph 3？C
A．They need more time to analyze data．
B．More children are needed for the research．
C．He is confident about the future of the project．
D．The research should be carried out in kindergartens．
21．What is the aim of the project？D
A．To offer Ethiopians higher paying jobs．
B．To make Amharic widely used in the world．
C．To assist Ethiopians in learning their first language．
D．To help Ethiopian kids read to learn in English．
