14．Parents might say"honesty is the best policy，"but when it comes to talking with their own children，mom and dad lie surprisingly often，finds a new study carried out by researchers in the University of Toronto，Canada．
Almost every parent in the study admits having come up with some tales to influence a child's actions and feelings．For example，a parent is annoyed by a child's crying and says，"The police will come to get you if you don't stop crying now．"In another example，an uncle has just died and the child is told that he has become a star to watch over the child．
Whether parents lie to benefit themselves or to protect the child，researchers suggest such tall tales could give children mixed messages at a time when they are trying to figure out how to deal with the social world．
Lies could also harm the parent-child relationship．It could even keep children from learning certain rules．"If I am always lying to the child in order to get the child to do X，Y，or Z，then they have never learned why they should do X，Y，or Z．"Heyman，one of the researchers，said．
Heyman also said，"It is common for parents to try out various ways，including lying，to guide a child，but most parents never think about how it will influence their child．I think parents should figure it out in advance what their general beliefs are，so when it comes to the situation you're working with your beliefs rather than what comes into your head at the moment．"

解答 21．D 细节理解题．根据文章第一段"but when it comes to talking with their own children，mom and dad lie surprisingly often，研究发现，父母在和孩子们说话中经常会说谎，故选D．
22．A 词义猜测题．根据文章内容researchers suggest such tall tales could give children mixed messages at a time when they are trying to figure out how to deal with the social world．such如果出现在某一名词前，那么该名词往往回指的是上文中的一些情况，所以要想知道tall tales的意思，要看看上文．上文提到了一些父母在跟孩子谈话中所涉及到的谎言例子，再根据后文"could give children mixed messages at a time when they are trying to figure out how to deal with the social world．"可以推断出tall tales 指的就是那些混杂着谎言的故事．故选A
23．C推理判断题．第三段提到"…such tall tales could give children mixed messages at a time when they are trying to figure out how to deal with the social world．"，由此可推断出，父母的谎言会影响孩子们对社会的理解，故选C．
24．B 细节理解题．最后一段提到Heyman说的一段话，其中"I think parents should figure it out in advance what their general beliefs are，so when it comes to the situation you're working with your beliefs rather than what comes into your head at the moment．"一句就是对父母的建议，由此可知他认为父母应该提前想清楚自己普遍信奉的原则，因此，一旦遇到类似的情况，你就会用你信奉的原则而不是一时冲动去处理问题．故选B．
