Question

【题目】There is bad news for students who like to use their mobile phones while they study. New research shows that students do not learn very well when they text. Researchers 【1】 （look）at 145 American high school students in the classroom. Some of the students used their mobile phones during class, while the others had their phones 【2】 (switch) off. The head researcher, Dr Jeffrey Kuznekoff, said students 【3】 did not use their mobile phones while the teacher was talking got 【4】 (high) scores on tests they took at the end of the class.

One of the biggest 【5】 (challenge) teachers have in the classroom is the non-stop battle of 【6】 (keep) students working because students were more absorbed in social media than learning. Many students felt they needed to be online and check messages even they had important work to do in class.

【7】 is very common for students to be 【8】 (physical) present in class, but mentally absent because they are using their mobiles. A study found that test scores increased 【9】 six percent after mobile phones 【10】 (ban) in class.

【解析】

试题分析：文章针对学生课堂带手机现象进行了调查，结果告诉我们课堂带手机影响学生成绩。建议禁止学生课堂带手机。

【1】looked.考查动词时态。此处讲一次调查的具体情况，调查已经发生且下文描述用的是过去时态，此处也用过去时，故填过去式looked。

【2】switched.考查动词时态。此处与前后句时态一致，讲述调查的具体情况也用过去式，故填switched。

【3】who/that.考查定语从句。句中包含定语从句，先行词是students，指人，在定语从句中作主语，要用关系代词who/that引导，故填who/that。

【4】higher.考查形容词比较级。此处指上课不用手机的学生比上课用手机的学生测试得分高，有比较的意思，故要用比较级，故填higher。

【5】challenges.考查名词。one of+复数名词，故填challenges。

【6】keeping.考查动词形式。Of是介词，后面用动词-ing形式，指让学生学习的战斗，故填keeping。

【7】It.考查形式主语。句中It作形式主语，不定式to be physically present in class作真正主语，故填It。

【8】physically.考查副词。此处修饰形容词present要用副词，指身体在教室。故填physically.

【9】by.考查介词。increased by“增加了”，此处指分数增加了6%，故填by。

【10】were banned.考查时态和语态。根据句意和increased可知用过去时态，句中mobile phones和动词ban是被动关系，指手机在课堂上被禁止。故填were banned。
