indithardtocontrolkids．D．Herkidsdependtoomuchonphones．A解析：推理判断题。由第二段中的Schoolisnotaboutbeingonyourphone可知，Madel

-daylearningbutthey’renotallowedtousesocialmedia(媒体)可知，画线词应该指的是一种电脑。学生们学习可以用，但是不允许使用社交网络。4．WhatdoesDr．JoanneOr

illpreventkidsbeingtech-minded．D．Itwillmakeeducationgoback60years．C解析：推理判断题。由倒数第一、二段可知，Dr．JoanneOrlando认为现在是科技时代，就应该让学生与时代接轨，禁止学生使用手机不符合这个时代的特征。Ⅲ七选

少年肥胖的几点因素。1．C解析：此空设于段中，与前文存在逻辑上的指代关系。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。

sengers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．who

m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r

eceiver是可数名词，故填receivers。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。
