一、完成句子1.WhatIwanttostress2.Itwashiscarelessdrivingthat3.Whenaskedtohelphimcheat4.withabookinhishand5.madeitahabittohelpthose二、阅读理解1.B。细节理解题。根据第二段最后‘Doctor,howlongshouldIspend?’Andthedoctorissaying,‘Idon’treallyknow.’和第三段第一句“因此怀特和他的团队决定通过监测自然环境调查,从英格兰近2万人中收集数据来找出答案”可知,研究想要弄明白的问题是,我们应在大自然中待多久。选项B符合题意。2.C。细节理解题。根据倒数第二段内容可知,White认为这一研究虽然涉及很多人,但这一研究结果只表明了相关性,结果是否能够经得起验证还需要进一步的调查。结合最后一段Iwanttobereallyclearaboutthis.Thisisinveryearlystages.可知,White的研究结论需要进一步研究。3.D。词义猜测题。根据画线部分前文可知,研究还处于早期阶段。从位置上判断,画线部分后的代词this指代threshold,根据thenextstep可知,this是指研究的起始阶段,再结合最后一句中的it’scertainlyastartingpoint.可知,画线部分意思为“起步阶段”。4.B。标题归纳题。通读全文尤其是第三段可知,与那些没有接触自然的人相比,在自然环境中至少待上两个小时的人——无论是一次待够两个小时还是数次合计两个小时——更有可能拥有良好的身体和心理健康。所以文章主要讲述了一项研究表明每周接触大自然两小时有益身心健康,短文的最佳标题为“在大自然中待两个小时”。三、语法填空1．that分析句子结构可知，所填词引导同位语从句，解释说明evidence的具体内容，从句中不缺少成分且意义完整，故用that引导。2．poorly修饰动词studied应用副词形式poorly。3．of/foramethodof/fordoingsth.做某事的方法。4．toperform此处是“主语＋be＋形容词＋不定式”结构，不定式用主动形式表示被动含义。5．havereported根据句中的时间状语inrecentyears可判断用现在完成时。6．belief根据空前的不定冠词a可知，此处应填believe的名词形式belief“看法，信念”。7．noting介词后接动词时，应用其动名词形式。respondbydoingsth.通过做某事
