2018高考英语七选五七选五讲解与训练题（含答案）2018高考英语七选五常考点有哪些？结合历年的高考题，总结如下：七选五题型主要考查上下文的理解与推断，虽然文章整体难度一般低于阅读理解，但是却给很多同学造成了很大的心理障碍。
七个选项中选五个，比四个选项中选一个，感觉干扰性更大，很大同学在做这个题目时，总有一种眼花缭乱、心烦气躁的感觉，致使往往正确率不高。
在这里提醒同学们，首先要克服心理障碍，同时要注意方式方法。
首先，要使用铅笔在试题上标识，确定出来的选项就用铅笔划掉，一旦发现选择有误，可以方便修改，减少干扰；第二，一定要注意文章开头的段落，文章第一段一般是主题段，会点明一篇文章要讲述的内容，做到心中有数；第三，注意设空前后的句子，因为这些句子之间是顺承和联系的，所有一定要联系和理解上下文的语境，找准原文中的关键词（组）和选项中的匹配信息。

孩子要不要买手机？什么时候给孩子买手机合适？为什么需要手机？如何规划手机产生的费用？文章就这些问题给出了适当的解释。
1．F细节支撑句。
根据文章的大意和本段首句中的关键信息词“At what age”可知，回答的问题涉及孩子的年龄，故选项F符合语境。
]2．B段落主旨句。
根据下一段中的两个if条件句，“如果你孩子不常离开你们……”和“如果你孩子很独立或常参加课外活动……”来确定该不该买手机，由此可推断出该段的标题为“How can you determine whether or not to buy a cellphone for your child”。
]3．D上下文过渡句。
由上一句提出的“the cost of having a cellphone”和后一句分析的几种选择的方式可知，此空该填入“Also be sure that he can be trusted to stay within his limits from month to month”。
此外，“Also be sure”与“Make sure”相呼应。
]4．G细节支撑句。
由前一句中的关键信息“discuss what it can be used for，rules...and consequences if he fails to follow them”即可推断出，“For example，is the phone only to be used to call family，or can it be used socially”符合语境。
G项举例说明了孩子该如何使用手机。
]5．E段落主旨句。
由空格后一句中的关键信息“these application programs allow you to track your child’s mobile activity”即可推断出E项符合语境。
E项中的“social media apps”与下文中的“these application programs”相照应。
