的指代关系。本句中的That指代的是前文中提到的数据30%ofthechildren。2．E解析：此空设于段中，与前文之间存在逻辑上的因果关系。前文陈述：毕竟，孩子和青少年需要营养来成长，此句进一步论述，所以对于他们来说，随着时间的流逝，体重增长是正常的。3．B解析：此空设于

段首，是本段的主题句。本段后面都是围绕此句展开说明基因是导致肥胖的一个原因。4．F解析：此空设于段中，与后文存在逻辑上的解释关系。此句说如今，人们的自由活动已经在很大程度上改变了，后面就这一点举例说明。5．G解析：

此空设于段尾，对前一句进行解释。前一句说孩子们爱吃零食，这并不总是他们的错，此句进一步解释说明：毕竟，在学校周围有很多提供各种各样零食的商店。Ⅳ语法填空Itookashortflighttheotherday．Thepassengersontheplane1．____________(offer

_____(build)upwillbesurprising．【解题导语】本文是一篇夹叙夹议文。本文作者通过讲述自己将飞机餐送给无家可归的人的故事，号召我们一起做善事。1．wereoffered解析：考查动词

的时态及语态。passengers和offer之间是被动关系，故用被动语态；再根据上下文的语境可知，此处表示过去的动作，故用一般过去时的被动语态。2．felt解析：考查动词的时态。此处表示过去的动作，因此用动词的一般过去

时。3．whom解析：考查关系代词。此处为“介词＋关系代词”引导的宾语从句，且指代人，故用whom。4．his解析：考查代词。因为后面跟名词dog，所以用形容词性物主代词，故用his。5．the解析：考查冠词。前面已经提到过sandwich，此处

再次提到，故用定冠词the。6．with解析：考查介词。sharesth．withsb．意为：与某人分享某物，故填with。7．Seeing解析：考查非谓语动词。句子的逻辑主语与see之间是主动关系，故用现在分词做状语。8．sincerely解析

：考查副词。修饰动词thanked，用副词sincerely，意为“真诚地”。9．receivers解析：考查名词。句意为：但是对于接受者来说，这可能是改变一生的行为。因为receiver是可数名词，故填receiver

s。10．built解析：考查非谓语动词。strength是被积累起来的，故用built作后置定语。
