day.,A,first part B,middle C,last part D,whole,解析,：,finale,是由,final,“,最后的”派生而来的，所以很容易就可确,定答案为,C,。,答案,：,C,【,实践应用,】,Most women in Ghanathe educated and,illiterate,，,the urban and rural,，,the young and oldwork to make money in addition to maintaining their roles as housewives and mothers.,Ninety percent of women 15 years of age and over are,married.Women,say they would like to have six or more

wife and mother of a large family.,How do these working mothers deal with their different roles in,the home and on the job?Some new ideas are being,tried.One,of,these is family planning to help reduce family,size.Another,helpful,measure is the day care center,，,but usually the fees are too high for,the,poor.Ghanaians,realize that more day care centers are,needed.Ghana,today is looking for new ways to meet the needs of,women and their families,，,so women can continue to play their roles,both in the home and in the economy.,The underlined word“illiterate”in the passage means _.,A,repeated B,rich C,uneducated D,sick,解析,：,illiterate,是由,literate,派生而来,，,由,literate,可联想起,literature,“,文化”，故而可知,literate,意为“有文化的，受过教,育的”。在,literate,前加上表示否定意义的前缀,il,当然就是“没,有文化的，没有受过教育的”。,答案,：,C,实战演练,A couple of years

Chinese journalists while I was just trying to put my luggage on the bus,，”,said Davis.,Known as the“Iron Hammer”for her punishing spikes(,扣球,),，,Lang made it possible for China to dominate in the sport in the early 1980s.She was a key player on Chinas 1984 Olympic gold,medalwinning,team.When the US team arrived for the Olympics,，,Lang,48,，,who is from Beijing,，,had to take a different route to avoid a crowd of reporters and fans.,Then came the greatest moment to Lang:while the US team was playing in a packed gym,，,at least 8,000 Chinese fans,unfurled,an American flag.,“That really says it all,，”,Davis said.“They look at her as an icon(,偶像,).Im sure its hard for them to see her coaching another country,，,but they love her so dearly that her success is their success.”,The loyalty of the Chinese fans was tested on Friday,，,when China lost a match to the US.,“Its a pity that China lost the match,，,but Im still glad that Lang,Pings,team won,，,since she is the pride of Chinas volleyball,，”,said Liu,Chengli,，,a spectator.“We also cheered for Langs victory.”,Lang says she just tries to stay professional when the two teams meet.“It doesnt matter if we play China or any other team.Its the same.”Lang said.,Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US.The reception from Chinese fans has touched the US players,，,said US volleyball player Lindsey Berg.,“Its such an honor to be here and play for our coach here in China,，”,she said.“The amount of support that the Chinese give to her and us has been tremendous.The whole event has been unbelievable.”,1,Whats the passage mainly about?,A,Staying professional.,B,Cheering for the Iron Hammer.,C,A match between China and the USD,Lang,Pings,career as a coach.,解析,：,主旨大意题。从全文可知，本文讲述了我国著名排球运,动员，现美国女排主教练郎平带队到中国参加奥运会受到了人,们的热烈欢迎，所以选,B,。,答案,：,B,2,Lang Ping avoided meeting the reporters and fans probably,because she _.,A,was
