【解析】

本文说明了上网太多对人们健康的影响，过多的上网会让我们更容易患病，更容易染上一些不好的生活习惯，让我们的免疫系统更脆弱。

【1】Spending 考查动名词用法。本句中动名词短语spending too much time online在句中作主语。句意：上网太多会增加你患感冒或流感的危险。

【2】a 考查固定搭配。短语catch a cold感冒；句意：上网太多会增加你患感冒或流感的危险。

【3】more likely 考查固定句式和比较级。句式:be likely to do sth可能做某事；句中有than说明本句应该使用比较级的形式。句意：那些上网成瘾的人要比那些上网少的人更容易患病。

【4】 in 考查固定搭配。短语lie in在于...；句意：研究人员认为原因在于那些上网成瘾的人更孤单，免疫系统更虚弱。

【5】weaker 考查比较级。本句是把上网成瘾的人和那些上网很少的人进行的比较，上网多的人免疫系统更虚弱，所以使用比较级。

【6】 themselves 考查反身代词。本句中反身代词themselves可以作为东西expose的宾语，构成expose oneself to...使自己接触...。

【7】have found 考查时态。本句的主语是recent study最近的研究，形容词recent在句中通常要和现在完成时连用。

【8】 worse 考查比较级。本句中worse与前半句中的greater和后句中的less、 more相呼应。句意：最近的研究发现上网多的人会经历更多的睡眠问题，有更糟糕的饮食习惯，锻炼更少。

【9】 behaviors 考查名词。本句中these加名词在句中作主语，动词behave的名词是behavior，these后面要接复数名词，所以使用behaviors。

【10】which 考查定语从句。本句中定语从句的先行词是other factors，关系代词which指代先行词在句中作主语。
