5．Never lose heart，________ difficulty you may meet with in your life．（　�。�
A．whatB．whateverC．howD．however

分析 無論遇到什么困難，永遠(yuǎn)不要灰心．

解答 答案是B．本題考查讓步狀語從句中連詞的選擇．首先排除A和C，what 和how 通常引導(dǎo)的是名詞性從句，不需要逗號與主句分開；根據(jù)句意和結(jié)構(gòu)判斷，本題需要的是引導(dǎo)讓步狀語從句的連詞；whatever無論什么，是形容詞性質(zhì)的連詞，常常做定語，而however無論如何，是副詞性質(zhì)的，常常做狀語；本題中需要的是名詞difficulty的定語，故答案選擇B．

點評 關(guān)于讓步狀語從句的考查，首先理解各連詞的含義和基本用法，積累讓步狀語從句中的特殊用法，最后結(jié)合語境合理判斷．

10．Meeting people from another culture can be difficult．From the beginning，people may send the wrong signal（信號）．Or they may pay no attention to signals from another person who is trying to develop a relationship．
Different cultures emphasize （強調(diào)） the importance of relationship building to a greater or lesser degree．For example，business in some countries is not possible until there is a relationship of trust．Even with people at work，it is necessary to spend a lot of time in"small talk"，usually over a glass of tea，before they do any job．In many European countries-like the UK or France-people find it easier to build up a lasting working relationship at restaurants or cafés rather than at the office．
Talk and silence may also be different in some cultures．I once made a speech in Thailand．I had expected my speech to be a success and start a lively discussion； instead，there was an uncomfortable silence．The people present just stared at me and smiled．After getting to know their ways better，I realized that they thought I was talking too much．In my own culture，we express meaning mainly through words，but people there sometimes feel too many words are unnecessary．
Even within Northern Europe，cultural differences can cause serious problems．Certainly，English and German cultures share similar values； however，Germans prefer to get down to business more quickly．We think that they are rude．In fact，this is just because the culture starts discussions and makes decisions more quickly．
People from different parts of the world have different values，and sometimes these values are quite against each other．However，if we can understand them better，a multicultural environment （多元文化環(huán)境） will offer a wonderful chance for us to learn from each other．

32．In some countries，eating together at restaurants may make it easier for people toA．
A．develop closer relations        B．share the same culture
C．get to know each other          D．keep each other company
33．The author mentions his experience in Thailand to show thatD．
A．the English prefer to make long speeches
B．too many words are of no use
C．people from Thailand are quiet and shy by nature
D．even talk and silence can be culturally different
34．According to the text，how can people from different cultures understand each other better？C
A．By sharing different ways of life． B．By accepting different habits．
C．By recognizing different values．   D．By speaking each other's languages．
35．What would be the best title for the text？B
A．Multicultural Environment     B．Cross-Cultural Differences
C．How to Understand Each Other  D．How to Build Up a Relationship．

17．In the US and Britain，the slogan around colleges was"Save water．Shower with a friend．"Now，Wuhan University has come up with another system for the campus bathhouse．It charges students for the amount of time in a shower．Before entering the bathhouse，students pay for the amount of time they want in the shower with cash or their student ID card．The clock starts ticking the minute the tape is turned on．It pauses when a button is pressed for soap．An integrated circuit （IC） card reader at each tap shows the time．No money，no water．The benefits of the new system
can be seen with the old system which charged 1 yuan for each person regardless of time in the shower．The university used  about 320 tons of water daily under the old system，but only 160 tons now．
     Many students use the new system but opinions on it are divided．Some students say it is  uncomfortable，because bathing had become a sort of race．Many people using it for the first time are not sure how long they need to shower．Some might be embarrassed if their time is UP and they're still covered in soap．They have to ask the bathhouse worker to help them buy extra time．
"It's a flaw in the system that you can not buy extra time on the ID card，"said Ren，a freshman．The University is also considering some student's suggestions that they be allowed to pay after they've finished the shower．Not surprisingly，some are complaining about losing the hour shower．But many students say the move helps them develop a water-saving sense．
     Without the time limit，most students tended to shower for half to an hour in the bathhouse．
     Some even used the hot water to wash their clothes．"In my experience，10-20 minutes is enough，"said Dai Zhihua，a third-year student who usually takes 8 minutes．
     A similar system has been installed in other universities．Shanghai Normal University introduced it at its Fengxiang Campus in September．The bathing fee there is 0.2 yuan per minute．One male student responded by setting a record with a two-minute shower．

41．According to the passage，which of the following is NOT true？A
    A．A student has to pay when a bath is over．
    B．The clock keeps timing except the pause for soap．
    C．If money runs out，there will be no water．
    D．Students pay for the amount of time they want in the shower．
42．The author's attitude toward the new bathhouse System in Wuhan University isD  
    A．critical          B．serious       C．a(chǎn)ppreciative       D．not mentioned
43，Since the new system was performed，Cof water has been saved．
    A．a(chǎn) quarter       B．one third      C．one half         D．two thirds
44．It can be inferred from the passage thatB   
    A．the new operation can solve the problem of water crisis
    B．the new operation can raise students'environmental awareness
    C．a(chǎn) similar operation will be set in other universities
    D．Most students spend less than half an hour showering in the bathroom．
45．In which column can you find this passage？C   
    A．People．   B．Society    C．Campus Life     D．Lifestyle．

14．Even when you're extremely busy，you aren't using your time with 100% efficiency．There are gaps in everyone's schedule where they aren't doing anything important．Even if your schedule has no gaps，there is probably lots of time where you aren't working as fast or as effectively as you possibly could．
Why aren't you completely efficient？It's because time isn't the limiting factor．If it were the limiting factor，people could work non-stop without breaks or any unproductive distractions（消遣）．Instead，people，even those who are highly productive，need to take breaks，occasionally procrastinate（拖延） and slow down on tasks throughout the day．
The real and most important limiting factor for productivity is your energy levels to pay attention．Energy levels limit your productivity because when you're tired，you can have ample time and still not get everything done．Your attention ability is also limited，because even if there are a million things that need to be done，you can only focus on one or two at a time．
You might not be able to insert another 4-5hours into your schedule without making some sacrifices（犧牲）．But even extremely busy people can add an hour or two into their schedule without cancelling anything．The reason it's hard to"find time"isn't a lack of time．It's because you don't have enough energy left to focus on something else that needs to fit into your day．
I first suspected time wasn't the real problem during an extremely busy period in my life over a year ago．I was insanely busy，but at that time I still exercised regularly．I had daily to-do lists with over twenty items，and I still found time to exercise．However，after a few weeks off，due to illness，I stopped exercising．I was not busy by any standards，in fact，my schedule was incredibly light．Despite this free time，I found it hard to find time to exercise．It seemed to get pushed later and later into my schedule until it was gone．How can I explain this odd experience？I believe you have known it．

26．If someone can't work with 100% efficiency，the most important limiting factor isD．
A．a(chǎn) schedule without gaps               B．breaks and distractions
C．the limited time                      D．the limited energy
27．According to paragraph 4，everyone，including the extremely busy people，canC．
A．work without any rest                   B．focus on many things at a time
C．find some more time in a day            D．do some exercise regularly
28．After a few weeks off，what was the change of the writer's life？B
A．He had a longer daily to-do lists with over twenty items．
B．He stopped doing exercise because of the lack of energy．
C．He found it hard to find time to exercise because he was busier．
D．He pushed most of the things later and later in his schedule．
29．The writer gives the example of himself in the last paragraph in order toA．
A．prove what the real limiting factor is
B．show us how busily he needs to work
C．explain how important a healthy body is
D．tell us what an odd experience he has
30．What is the best title of the passage？A
A．Are You Really Lack of Time？
B．How Can You Work Efficiently？
C．What Makes Your Energy Limited？
D．When Should You Do Exercise？
