13、etic radiation with a very short wavelength that produces a high amount of energy.While its true that light can damage our eyes under certain circumstances,theres no scientific evidence suggesting that blue light is harmful to our eyes.But many people still think it is,which is why blue-light-blocki

30、移开。根据文章第二段第一句 How daycare negatively affects children is related to many factors.可知,日托对儿童的负面影响与许多因素有关。上文提到了日托的好处,下文具体论述了日托的缺点,故此空应该引出日托的缺点。A项意为“但是日托也有它的缺点”,承上启下,符合语境。故正确答案为A。2.【解析】选D。根据上文可知,另一项研究表明,当一个人表现出压力迹象时,体内会释放出荷尔蒙皮质醇,害羞的儿童的荷尔蒙皮质醇水平更高。故此空应该与解释为什么害羞的儿童体内会释放出更高水平的荷尔蒙皮质醇有关。D项意为“这是因为一个害羞的孩子不会在公共场合

31、敞开心扉”,承接上文,符合语境。故正确答案为D。3.【解析】选E。根据下文可知,因此,对一个孩子来说,与他或她的母亲建立深厚的关系是至关重要的,因为这将为他或她今后在生活中形成的所有关系奠定基础。故此空应该与为什么婴儿和母亲建立深厚的关系是至关重要的有关。E项意为“婴儿变得非常依恋他们的主要照顾者”,引出下文,符合语境。故正确答案为E。4.【解析】选F。根据上文可知,在日托中心,当一个看护人同时照顾多个孩子时,她可能无法深入了解为什么一个孩子过得好或不好。故此空应该与看护人无法深入了解为什么一个孩子过得好或不好的后果有关。F项意为“在这种情况下,孩子可能变得完全安静或好斗”,承接上文,符合语境

32、。故正确答案为F。5.【解析】选C。根据上文可知,日托的另一个消极的方面是,如果孩子们与生病的孩子接触,他们更有可能生病。根据下文可知,维护良好的日托中心通过提供精心设置的环境为孩子的全面发展做出了巨大贡献。上文阐述了日托的缺点,下文论述了日托的优点,上下文存在转折,故此空应该引出日托的优点。C项意为“然而,日托的好处是不能忽视的”,承上启下,符合语境。故正确答案为C。.应用文写作假定你是李华,你校即将举行“给农村小学捐书”(Donating Books to Rural Primary Schools)活动,现向全校招募志愿者,你的笔友Peter来信向你咨询有关情况,请你写一封回信,要点如下
