题目内容
13．-Tom，get up early and read more Chinese text books，please．It'shelpful for your Chinese study．（ help ）-Ok，mom．
分析 -汤姆，请早起多读中文教科书．它对你的汉语学习是有帮助的．
-好的，妈妈．
解答 答案：helpful
联系语境，根据关键词It's是It is的缩写，所以系动词is后应该跟形容词；结合提示词这里应为名词help"帮助"，其形容词形式为helpful"有帮助的"，这里是指：它对你的汉语学习是有帮助的．符合句意及用法．故填：helpful
点评 此题考查名词和形容词之间的转化．做题时联系关键词确定出正确的词性是解题的关键．
