    19．Some passers-by witnessed the car accident  _______  five passengers were killed，a baby included．（　　）
    A．thatB．whichC．in whichD．in that

    分析 一些路人目睹了这起车祸，在车祸中，有五名乘客丧生，其中包括一个婴儿．

    解答 答案：C．
    本句中先行词the car accident，定语从句中缺少状语成分，结合先行词可知用in which来引导，相当于where．D项结构错误，介词加关系代词指物时用which，指人时用whom；that和which在从句中只能用作主语或定语，不能作状语；故选C．

    点评 在定语从句中，关系副词=介词+关系代词which；同时要分析定语从句的句子结构，如果句子很完整就使用关系副词，如果句子中缺少主语，宾语，表语或者定语就使用关系代词．

    10．Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic （流行病） sweeping across
    America's farmland．It has little to do with the usual challenges，such as flood，rising fuel prices
    and crop-eating insects．The country's farmers are getting older，and there are fewer people standing in line to take their place．National agricultural census （普查） figures show that the fastest-growing group of farmers is the part over 65．Merrigan is afraid the average age will be even higher when the 2012statistics are completed．
    Merrigan，a former college professor，is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture．Aside from trying to stop the graying of America's farmers，her work is made tougher by a recent blog posting that put agriculture at No.1on a list of"useless"college degrees．Top federal agriculture officials are talking about the posting，and it has the attention of agricultural organizations across the country．
    "There couldn't be anything that's more incorrect，"Merrigan said．"We know that there aren't enough qualified graduates to fill the jobs that are out there in American agriculture．"
    In addition，a growing world population that some experts predict will require 70% more food  production by 2050，she said．
    "I truly believe we're at a golden age of agriculture．Global demand is at an all-time record  high，and global supplies are at all-time record lows，"said Matt Rush，director of the Texas Farm Bureau．"Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture．"
    The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food．The National Young Farmers'Coalition has also been pushing for state and federal policy changes to make it easier for new farmers．
    Ryan Best，president of Future Farmers of America，has been living out of a suitcase，traveling the country and visiting with high school students about careers in agriculture．The 21-year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics．"Never before have we had the innovations （创新） in technology which have led to agriculture in this country being the most efficient it has ever been，"he said．"There's really a place for everybody to fit in．"

    59．What is the new challenge to American agriculture？A

    A．To draw federal agriculture officials'attention．

    A．the government will cover production costs
    B．global food supplies will be even lower
    C．investment in agriculture will be profitable
