When we wake up feeling sleepy and with dark circles under eyes, many of us often think: “I’m going to go to bed earlier tomorrow!” But however determined we are, chances are 【1】 we don’t stick to our promise. This behavior 【2】(call) “bedtime procrastination (拖延症)” is common in our daily life.

In a study, 53 percent of the 2,400 【3】(participate) said they didn’t follow their sleep schedule, delaying it at least twice 【4】 week. It is found that they delayed bedtime not because they liked to stay up late, but they couldn’t stop 【5】(do) other unimportant things, which were keeping them up in the first place.

“People who generally have trouble resisting temptations and sticking to their intentions are more likely to delay going to bed.” Floor Kroese, a psychologist 【6】(far) explained to HufPost.

Yet, according to scientists, lack of self-control is not the only thing 【7】(blame). Our body clock also plays an important role when 【8】comes to bed time. To check the influence of the body clock 【9】 sleep, scientists studied the sleep patterns of 108 people. It has been found that those who get up late 【10】(be) more likely to postpone their bedtime than those who wake early every morning. The choices we make that affect our sleep could turn out to be pretty important for our health.

【解析】

这是一篇说明文。文章讲述了日常生活中，人们总是熬夜这一现象，并分析了原因。

【1】

考查表语从句引导词。__1_ we don’t stick to our promise是一个表语从句，从句不缺任何成分，也没有实际意义，应用引导词that。故填that。

【2】

考查过去分词。本句已有系动词is，且无连词，此处用非谓语形式，名词短语This behavior和动词call是逻辑上的被动关系，应用过去分词表被动，作名词短语This behavior的后置定语。故填called。

【3】

考查名词的数。该空做句子主语，用名词形式，2,400后面加名词复数，participant（参加者）是可数名词，用participants。故填participants。

【4】

考查冠词。本句意为“在一项研究中，2400名参与者中有53%的人说他们没有遵守自己的睡眠计划，一周至少推迟两次。”此处泛指“一周”，week以辅音音素开头，用不定冠词a。故填a。

【5】

考查动名词。本句意为“研究发现，他们推迟就寝时间，并不是因为他们喜欢熬夜，而是他们不能停止做一些无关紧要的事情，这些因素让他们得以继续前进。”此处指“停止做某事”，stop doing sth.（停止做某事），应用动名词（doing）。故填doing。

【6】

考查副词。本句意为“一位心理学家Floor Kroese进一步向HufPost解释道。”此处表“进一步”，用副词修饰动词explained。故填further。

【7】

考查动词不定式。本句已有系动词is，且无连词，此处用非谓语形式；the first/ second...，the last，the only，the next以及这些词修饰的名词后，常接动词不定式作定语，名词thing由the only修饰，应用动词不定式（to do）作名词thing的后置定语。故填to blame。

【8】

考查代词。固定句型when it comes to（当提及/谈及），应用代词it。故填it。

【9】

考查介词。固定搭配influence on（对……产生影响），应用介词on。故填on。

【10】

考查主谓一致。 分析句子结构 that those who get up late 　　　　　10　　　　　(be) more likely to postpone their bedtime than those who wake early every morning. 是一个主语从句。在主语从句中，who get up late 是一个定语从句，修饰先行词those。在主语从句中，主语是those，是复数，且文章讲的是现在的事实，谓语动词用一般现在时。主谓一致，谓语用are。故填are。
