分析 铅中毒是儿童中常见的疾病,辨别儿童体内铅的含量十分重要.本文讲述了铅中毒对儿童的危害,呼吁家长要谨慎,保护孩子免受铅的危害.
解答 71.poisoned 根据文章第一句话"Lead poisoning occurs when lead is presented in high level in the blood of a person"可知,如果血液中含铅量高,人会中毒.空格后有by lead,所以用被动式poisoned.
72.uncommon 根据文章第一段中的第二句话"It is the most common medical problem found in children"可知,小孩铅中毒是很常见的,空格前有not,所以用common的反义词uncommon.
73.access 考查固定短语.根据文章第二段中的"children born in poor families have higher chances of getting exposed to lead"可知,来自穷人家庭的孩子更有可能有铅中毒的风险. have acess to 是固定短语,意思是可以接近.
74.Symptoms 考查归纳概括能力.根据第三段中的内容"Some of the common symptoms of lead poisoning in children are headaches,stomach pain,hair loss,muscle weakness,weight loss,ect."可知,空格右边都是铅中毒的症状,所以用Symptoms.
75.Effects考查归纳概括能力.根据文章第四段中的内容"Lead poisoning can have severe effects and can lead to heart diseases"可知铅中毒对人的身体有严重的影响.所以用effects.
76.cause 考查同义转换.文章中是 result in,意思是导致,用一个词代替就是cause.
77.regular 考查词性转换.根据文章最后一段中的第二句话"Cleaning the house regularly and removing shoes at the door"可知答案,空格处是修饰名词,所以用形容词形式.
78.reduce 考查词形转换.根据文章最后一段中的倒数第二句话"Usually,oral medicines are given to the child,while sometimes,they're injected for reducing the lead level"可知答案.空格前有不定式to,所以用动词原形.
79.treated 考查词性转换. 根据第五段的最后一句话"Children who have very high level of lead in their blood would need treatment for a long period of time"可知答案. 空格中应该用被动语态,所以用treated.
80.variety考查归纳概括能力.根据文章最后一段的第三句话"Children should be put on a healthy diet,containing high proportions (比例) of calcium and iron,such as eggs,milk,fruits,potatoes,ect."可知,应该给孩子各种各样的健康食物. a variety of是固定短语,意思是各种各样,多种多样.
点评 在答题中,应分四步来答题:掌握文章大意,理清短文结构,分析表格结构,确定表格答案在原文中找出问题.在原文段落中,找出题干所包括的信息部分,这样就可以快速准确地抓住有效信息,确保答题的准确性.
