18．Barrack Obama's recent visit to the Asian nations clearly sent a message to the world     Asia is important in America's global partnership．（　�。�
A．whichB．whereC．thatD．what

分析 巴拉克．奧巴馬最近對(duì)亞洲一些國(guó)家的訪(fǎng)問(wèn)很明顯向世界傳達(dá)了一個(gè)信息：亞洲在美國(guó)全球伙伴中很重要．

解答 答案：C
題干中Asia is important in America's global partnership是解釋message的內(nèi)容，是一個(gè)同位語(yǔ)從句；同位語(yǔ)從句要用that來(lái)引導(dǎo)，且不可省略．故選C．

點(diǎn)評(píng) 同位語(yǔ)從句屬于名詞性從句，大多由從屬連詞that引導(dǎo)，常常跟在fact，idea，opinion，news，hope，belief等名詞后面．同位語(yǔ)從句一般用來(lái)解釋或說(shuō)明這些名詞的具體含義或內(nèi)容，在邏輯上表現(xiàn)為同位關(guān)系．

20．We often hear that children wish they（61）were（be） grown-ups，and that old people wish to be young．Each age has its own pleasures and its own pains．The happiest people enjoy（62）whateach age gives them without wasting their time in（63）useless（use） regrets．
Childhood is a time when there are few duties．A child（64）is fed（feed），looked after and loved by all grown-ups like parents or grandparents．What's more，life is always giving new things to him．（65）However，for older people they often lose their interest in those things．
On the other hand，a child may also have some pains with him．He is not so free to do what he wishes to do．He is often told not to do something．He will certainly be shouted（66）atfor doing something wrong．When a child grows up，he can no longer expect others（67）to pay（pay） for his food，〔lothes and many other things．And if he wants to live（68）comfortably（comfort），he has to work．If he still  spends most of his time（69）playing（play）as he used to in childhood，he will go hungry．If，however，he works hard and has no trouble，he can build up his own position  in  society  with great（70）happiness（happy）．

6．All of us should keep a kitchen diary，showing how much food are left uneaten as garbage．
We all waste food，you and me millions of tons of it．In China，enough food is wasted in restaurants every year to feed 200million people．In the United States，40percent of food is wasted from farm to fork．Each year，the amount of food thrown away in rich countries is almost the same as that produced in sub-Saharan Africa．This raises some important questions．
In developing countries，food is lost because farmers do not have appropriate cooling，storage or market access for their crops．Their grains，fruits and vegetables dry up and rot away．In developed countries，the picture is different，and food is wasted in supermarkets，restaurants and at home．China faces both problems，significant losses in farms，as well as at the sale and consumption stages．And the amount of food wasted by Chinese consumers is rapidly increasing．
Consumer culture has filled China and urban residents can get quality food from anywhere in the country and from across the planet．Chinese consumers are as particular about their food as those in other countries．In supermarkets，they refuse to buy vegetables that don't look fresh or have an irregular shape，or milk and other products close to their expiry （失�。� date．
Besides，Chinese consumers tend to be generous．In restaurants or at home，often too much food is ordered or cooked and served．So while trooping out of a restaurant，full and happy，with colleagues or friends，they never look back at what's left untouched on the table．Should Chinese consumers take more responsibility for the waste they create？
Everyone deserves to have enough food to eat．Despite China's impressive success in reducing hunger over the past three decades，the job is not completed yet．

31．According to paragraph 1，we know that food waste isA．
A．huge worldwide
B．mainly in USA
C．only in rich countries
D．just in African countries
32．In developing countries，food is lost mainlyA．
A．for the lack of cooling and storage
B．because of easy access to markets
C．because of the wet weather
D．because of the quality of the food
33．The main reason for food waste in China isA．
A．the effect of consumer culture
B．the convenient food supply
C．the worry about food quality
D．people's being particular about it
34．How do Chinese feel when they leave restaurants with much food left behind？A
A．Generous．
B．Unconscious．
C．Wealthy．
D．Valuable．
35．The purpose of the passage is to tell usA．
A．not to waste any food from now on
B．the necessity to improve food quality
C．the fact of food waste in developed countries
D．the influence of consumer culture on Chinese．

13．The air quality has worsened in the Chinese capital since Wednesday，causing renewed discontent among residents．
Without rainfall and wind to decrease pollutants，particulate matter（顆粒物質(zhì)） has been accumulating in the air．Most monitoring stations measured PM 10 （particulate matter smaller than 10 micrograms） at higher than 300 micrograms per cubic meter．In southwestern Beijing's Fangshan District，the Liangxiang station recorded 516 micrograms of PM 10 per cubic meter，the highest reading of the day，according to the Beijing Municipal Environmental Monitoring Center．More than 150 micrograms is considered harmful to health．
Beijing has been covered by heavy smog off and on this winter，and the ongoing air concerns are wearing on residents，particularly as they prepare to celebrate the Spring Festival holiday next week．"I almost got choked by the smog when I stepped out of the office building on Wednesday，"said Yang Yanli，24，an accountant．"The smell is so terrible，as though I'm inhaling lots of coal，that it has spoiled my holiday mood．"

The National Blood Service，which covers all of England and North Wales，needs nearly two and a half million blood donations each year．When you give blood，you'll be doing one of the most amazing things anybody could dream of-saving a life．
                                
All types of blood are needed-not just rare ones．In fact，the commoner the blood type，the more are needed．So even if your blood is one of the most common types-group O for example-you can be sure that by donating three times a year，you really are doing something amazing．
