分析 鉛中毒是兒童中常見的疾病,辨別兒童體內(nèi)鉛的含量十分重要.本文講述了鉛中毒對兒童的危害,呼吁家長要謹(jǐn)慎,保護(hù)孩子免受鉛的危害.
解答 71.poisoned 根據(jù)文章第一句話"Lead poisoning occurs when lead is presented in high level in the blood of a person"可知,如果血液中含鉛量高,人會中毒.空格后有by lead,所以用被動式poisoned.
72.uncommon 根據(jù)文章第一段中的第二句話"It is the most common medical problem found in children"可知,小孩鉛中毒是很常見的,空格前有not,所以用common的反義詞uncommon.
73.a(chǎn)ccess 考查固定短語.根據(jù)文章第二段中的"children born in poor families have higher chances of getting exposed to lead"可知,來自窮人家庭的孩子更有可能有鉛中毒的風(fēng)險(xiǎn). have acess to 是固定短語,意思是可以接近.
74.Symptoms 考查歸納概括能力.根據(jù)第三段中的內(nèi)容"Some of the common symptoms of lead poisoning in children are headaches,stomach pain,hair loss,muscle weakness,weight loss,ect."可知,空格右邊都是鉛中毒的癥狀,所以用Symptoms.
75.Effects考查歸納概括能力.根據(jù)文章第四段中的內(nèi)容"Lead poisoning can have severe effects and can lead to heart diseases"可知鉛中毒對人的身體有嚴(yán)重的影響.所以用effects.
76.cause 考查同義轉(zhuǎn)換.文章中是 result in,意思是導(dǎo)致,用一個詞代替就是cause.
77.regular 考查詞性轉(zhuǎn)換.根據(jù)文章最后一段中的第二句話"Cleaning the house regularly and removing shoes at the door"可知答案,空格處是修飾名詞,所以用形容詞形式.
78.reduce 考查詞形轉(zhuǎn)換.根據(jù)文章最后一段中的倒數(shù)第二句話"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,所以用動詞原形.
79.treated 考查詞性轉(zhuǎn)換. 根據(jù)第五段的最后一句話"Children who have very high level of lead in their blood would need treatment for a long period of time"可知答案. 空格中應(yīng)該用被動語態(tài),所以用treated.
80.variety考查歸納概括能力.根據(jù)文章最后一段的第三句話"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,應(yīng)該給孩子各種各樣的健康食物. a variety of是固定短語,意思是各種各樣,多種多樣.
點(diǎn)評 在答題中,應(yīng)分四步來答題:掌握文章大意,理清短文結(jié)構(gòu),分析表格結(jié)構(gòu),確定表格答案在原文中找出問題.在原文段落中,找出題干所包括的信息部分,這樣就可以快速準(zhǔn)確地抓住有效信息,確保答題的準(zhǔn)確性.
