    9．People who do not get enough vitamin A in their diet may develop night blindness．But in the developing world a lack of vitamin A causes much more serious harm to children．The World Health Organization links the lack of vitamin A to as many as 250.000 child deaths every year．
        One excellent source of vitamin A is found in sweet potatoes with orange flesh．Orange sweet potatoes contain high levels of beta-carotene（胡萝卜素），which our body can change into vitamin A． Experts say orange sweet potatoes specially bred （育种，培植） for growing conditions in Africa
    could help solve the lack of vitamin A there．
         But，first，more people will need to be persuaded to eat them． Jan Low with the International Potato Center，a research organization says the sweet potato needs a better image in Africa． Jan Low says，…We do have an image problem with sweet potato in general in sub-Saharan Africa． It is seen as a crop of the poor．"Ms Low explains that sweet potatoes are mainly grown by poor women to feed their families in case another crop fails． The sweet potatoes commonly grown if Africa have white or yellow flesh． But，more importantly，they are low in vitamin A．
        Jan Low took part in a project to study how best to market orange sweet potatoes to Africans．She worked on an information campaign in Mozambique and Uganda．The campaign included radio messages about the nutritional benefits of the orange sweet potato．They advertised its ability to"fight diseases，make you strong，clear your skin and make you look healthy．"In areas without radio，the campaigners spread the message through community theater．The performances included singing，dancing and storytelling．And everywhere they went，the campaigners wore orange T-shirts and hats．They even drove orange vehicles．Jan Low says the color made it easier to gain public attention．
       Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization． He points toefforts in the past to increase the popularity of other nutritious crops． He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat．But Mr．Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa． For one thing，except for the color，the vegetable is similar to what people already use．
    66．What does the writer want to tell us in Para． 1？B
    A． Vitamin A in food may cause night blindness．

    19．Leaders of the World Health Organization say they are concerned about the air quality and health efiects on citizens during a recent outbreak of heavy pollution in Beijing．Still，they said they were unsure of the exact amount the air pollution takes on any person's body，casting doubts on local reports tying the area's dirty air to particular cases of illness．
       Speaking at a briefing（情况介绍会）on Tuesday，the WHO's Western Pacific regional director，Shin Young-Soo，cited（列举）reports about poor air quality causing lung cancer in recent weeks．
    "The WHO is skeptical of the information，"she said．"We're cautious of whether the illness is related to air po11ution．We know it has an impact on health，but we don't know how much．"
        The officials didn't cite particular reports．The comments follow a number of articles since late last year connecting some cases of diseases like lung cancer with pollution，．including one in November regarding an 8-year-old girl．
       The health impact of Beijing's gray skies has been on the minds of many over the past week．Local authorities on Tuesday preserved an orange alert（警报）一the city's second highest pollution-warning level-and again warned people to stay indoors．Experts widely agree that small particulates（颗粒） known as PM2.5 carry significant short-and long-term health risks，particularly with children．Other studies find a certain link between pollution and shorter life spans．
    Chinese state media have noted a rise in cancer levels in Beijing，without specifying（具体说明）whether the new cases are the main result of pollution，smoking，other sources or some combination．
    Bernhard Schwartlander，the organization's China chief，said he is concerned and has been in contact with national authorities．"There is no easy solution，"Dr．Schwartlainder said，adding that solving the problem requires managing industry and the economy．WHO leaders advised citizens．to stay indoors and limit exposure to the harmful particulates．When asked if wearing a face mask has any proven efficacy in preventing health effects of air pollution，Dr．Schwartlainder said，"Whatever you do，it's better than nothing．"

    68．We can learn from the passage thatA．
    A．in case of an orange alert，we had better not go outside
    B．the case of the girl with lung cancer was little'linked to air pollution
    C．cancer levels in Beijing are rising due to heavy air pollution
    D．it is widely agreed that pollution shortens life spans very slightly
    69．According to Dr．Schwartlander，the ways to solve the problem includeC．
    A．contacting the national authorities     
    B．being exposed less to harmful particulates
    C．managing the enterprise and economy  
    D．preventing health effects of pollution
    70．What would be the best title of this passage？D
    A．The dangers of heavy pollution
    B．The impacts of pollution on health
    C．The importance of protecting the environment
    D．The uncertainty of relationship between pollution and health．
