B 細(xì)節(jié)理解題。文章提到了 “the 1986 Chernobyl disaster” 和 “Japan ’ s Fukushima Daiichi nuclear power plant accident” 兩起核輻射事故,故選 B。 2. B 正誤判斷題。由第四段可知 B 項(xiàng)正確。由第二段可知大氣中發(fā)生的事故才會(huì)在全球范圍內(nèi)影響出生嬰兒的性別,故 A項(xiàng)錯(cuò)誤;由倒數(shù)第三段可知日本核電站發(fā)生的事故會(huì)影響到美國(guó),故 C項(xiàng)錯(cuò)誤;核輻射只會(huì)相對(duì)地減少女嬰的出生數(shù)量,故 D項(xiàng)錯(cuò)誤。 3. D 細(xì)節(jié)理解題。由倒數(shù)第二段可知 “ 核輻射會(huì)對(duì)精子的 X染色體造成損害 ” ,故 D項(xiàng)正確。 4. A 主旨大意題。文章開篇點(diǎn)題,向我們說明了文章的主要內(nèi)容:根據(jù)一項(xiàng)新研究,核電站核泄漏事故和炸彈試驗(yàn)釋放的放射性物質(zhì)導(dǎo)致全世界女嬰出 生數(shù)量減少了數(shù)百萬。由此可見 A項(xiàng)最能概括全文。 Ⅲ .書面表達(dá) 為紀(jì)念北京奧運(yùn)會(huì)成功舉辦,將每年 8月 8日定為 “ 全民健身日 ” ,請(qǐng)你根據(jù)以下內(nèi)容提示介紹這一活動(dòng)并提倡大家參與: 1. 全民健身倡導(dǎo)全民參與,以青少年和兒童為重點(diǎn),旨在提高國(guó)民體質(zhì)和健康水平; 2. 全民做到每天參加一次以上的體育健身活動(dòng),學(xué)會(huì)兩種以上的健身方法,每年進(jìn)行一次體質(zhì)測(cè)定; 3. 活動(dòng)當(dāng)天,所有的公共體育設(shè)施免費(fèi)開放。 注意: 1. 詞數(shù) 100左右; 2. 可適當(dāng)增加細(xì)節(jié),以使行文連貫; 3. 參考詞匯 全民健身日 National Fitness Day。 范文: National Fitness Day, which falls on August 8, is to memorate the opening of the 2021 Beijing Olympics. Aimed at improving the whole nation’ s health condition, it focuses on mass participation in sports, especially that of teenagers and children who shoulder our country’ s future. All the citizens are encouraged to take exercise more than once every day, master at least two forms of body building and be examined once a year. On that day, all public sports facilities will be open for free, which reflects the Olympic spirit and provides the public with more opportunities to exercise. As is known to all, regular exercise contributes to a healthy body and a healthy mind. So, take part and you will certainly benefit.
