题目解答
答案
(1)考查动词时态语态。句意:这位儿科医生发现,躺在母亲胸前睡眠的两天大婴儿比躺在婴儿床上睡得更好。主句用一般过去时态,可知宾语从句也用一般过去时态描述过去的事情,place和主语之间是被动关系,所以用被动语态,主语who指代的先行词为those,故填were placed。
(2)考查it的用法。句意:研究人员担心,独自睡觉会让母亲和孩子更难亲近,并损害大脑的发育,导致孩子在成长过程中出现不良行为。动词不定式作真正宾语的放在后面,所以用it作形式宾语,故填it。
(3)考查现在分词。句意:研究人员担心,独自睡觉会让母亲和孩子更难亲近,并损害大脑的发育,导致孩子在成长过程中出现不良行为。指代前面句子的直接结果,所以用现在分词作结果状语,故填leading。
(4)考查情态动词。句意:南非开普敦大学的尼尔斯•伯格曼博士说,为了理想的发育,健康的新生儿在最初几周应该睡在母亲的胸前。表示"应该",后跟动词原形,所以用情态动词,故填should。
(5)考查连词。句意:在那之后,他们应该呆在妈妈的床上,直到他们三岁甚至四岁。表示"直到",所以用连词until引导时间状语从句,故填until。
(6)考查动词时态。句意:通过监测发现,当婴儿独自睡觉时,他或她的心脏承受的压力是正常情况下的三倍。宾语从句用一般过去时态,可知描述过去的事情,所以主句也用一般过去时态,故填revealed。
(7)考查固定搭配。句意:通过监测发现,当婴儿独自睡觉时,他或她的心脏承受的压力是正常情况下的三倍。本句为"倍数+as+形容词/副词原级+as"句型,后面的as省略了,故填much。
(8)考查动词不定式。句意:躺在婴儿床上也会影响睡眠,婴儿的大脑不太可能在活跃睡眠和安静睡眠两种睡眠模式之间过渡。be likely to do sth."可能做某事",为固定搭配,故填to make。
(9)考查形容词比较级。句意:在小床上,16个人中只有6个人睡得安稳,而且睡眠质量差得多。前面有修饰比较级的far,所以用形容词比较级作表语,故填worse。
(10)考查介词。句意:实现这种转变被认为是大脑正常发育的关键。the key to"……的关键",为固定搭配,to为介词,故填to。
(2)考查it的用法。句意:研究人员担心,独自睡觉会让母亲和孩子更难亲近,并损害大脑的发育,导致孩子在成长过程中出现不良行为。动词不定式作真正宾语的放在后面,所以用it作形式宾语,故填it。
(3)考查现在分词。句意:研究人员担心,独自睡觉会让母亲和孩子更难亲近,并损害大脑的发育,导致孩子在成长过程中出现不良行为。指代前面句子的直接结果,所以用现在分词作结果状语,故填leading。
