BwordCpromise Daction解析：从上文提到年轻人身无分文地走进这家餐馆吃饭，正苦于没钱付账时，人家却认为这20美元是自己丢的，他认为自己没有那么幸运。答案：A12A.message BsignalCmark Dtip解析：年轻人在餐馆吃饭后，按照西方人的习惯，应该是付小费，故本句中要选tip，指“小费”。 答案：D13A.what BhowCwhere

Dshops解析：年轻人当时是在餐馆得到了别人的帮助，故他发迹之后要施舍的地方，从其感情因素考虑，应该是饭店，而不可能是其他场所。答案：A.阅读理解It is a question that has confused parents for decades：why do children refuse to eat greens?Now，two American experts believe they have the answer.After studyingdozens of babies as they played with various objects，the researchers noted that they were far more unwilling to grasp plants than other things.They believe this is because evolution (生物进化) has biologically made children be wary of plants.Due to susceptibility (敏感性) to illness or injury in the early years of life，the body has designed an inner defence mechanism (内部保护机制) that limits a childs contact with plants，they think.The researchers believe this is why babies in the study were afraid of grabbing plantsand why children turn their noses up when faced with a plate of broad beans.The findings are published in a paper by Dr Annie E Wertz and Dr Karen Wynn，both psychologists at Yale University.They wrote，“Throughout human evolution .plants have been essential to human existence.Yet，for all of these benefits，plants have always caused very real dangers.”“Plants produce toxins (毒素) as defences that can be harmful，or even deadly.Some plants also employ physical defences，such as thorns and poisonous oils that can damage tissues (组织) and cause effects over the whole body.”They added，“We predicted that babies may have behavioural strategies that reduce their exposure to dangers posed by plants by minimising their physical contact with plants.”To test their theory，the researchers studied how children aged eight to 18 months old reacted when presented with a variety of objects.It took much longer for children to grab plants；objects that were faked to look like plants also caused a slow response time.For parents attempting to spoon some peas into the mouth of their child，this finding should come as welcome relief.语篇解读有一个问题困扰了父母很长时间，那就是为什么孩子们拒绝吃蔬菜。现在科学家似乎找到了答案，那就是早期人类的生存本能决定了婴儿会尽量少地接触绿色植物。1.What does the underlined word “wary” in the third paragraph mean?ACurious. BAfraid.CTired. DCertain.解析：词义猜测题。从上下文来看，孩子们不愿意碰触绿色植物，也不愿意吃蔬菜，是因为从生物学上看他们“害怕”绿色植物。答案：B2What did early humans probably do to survive?AThey chose to make more artificial things.BThey forbade their children to touch plants.CThey chose to have little contact with plants.DThey tried very hard to escape from predators.解析：细节理解题。根据下文可知许多植物为了抵抗掠食者，会产生毒素或者生长出一些抵抗的器官。这些对于早期的人类来说是有威胁的甚至是致命的，因此为了生存，人们产生了内在
