分析 我想和大家談?wù)勌帐卟,并且向你們展示太空蔬菜很健康,?duì)大家很有好處.
太空蔬菜是由被帶去外太空又從外太空帶回來(lái)的種子所種植的.這些種子受了外太空上輻射和低引力的影響.當(dāng)它們被帶回地球時(shí),這些種子種出的蔬菜比平常的更大,更健康,更有營(yíng)養(yǎng).然而,有些人卻對(duì)吃太空蔬菜感到擔(dān)憂.他們覺(jué)得太空蔬菜也許對(duì)我們沒(méi)什么好處,并且在太空中暴露在了輻射下,也許會(huì)致癌.人們無(wú)需害怕,因?yàn)樘帐卟藢?shí)際上是非常健康的.以下是一些關(guān)于太空蔬菜大家需要了解到的情況:太空蔬菜的種子是被認(rèn)真挑選過(guò)的.當(dāng)種子從太空帶回來(lái)時(shí),人們對(duì)它們進(jìn)行測(cè)試以保證它們能安全生長(zhǎng)來(lái)給我們吃.測(cè)試后已經(jīng)沒(méi)有輻射的痕跡了對(duì)大家來(lái)說(shuō),太空蔬菜比普通蔬菜更好.比如,太空蔬菜可以在二十天內(nèi)保持新鮮,這比普通蔬菜時(shí)間長(zhǎng)兩周.另一種受歡迎的太空蔬菜是辣椒.太空椒比普通椒富含多百分之二十的維生素C.轉(zhuǎn)基因食品在市面上出現(xiàn)后,人們總擔(dān)心他們?cè)诔圆幻魑铮热纾绻褕?jiān)果的基因放在土豆里,吃了這些土豆,對(duì)堅(jiān)果過(guò)敏的人就會(huì)覺(jué)得惡心,因?yàn)樗麄儾恢浪麄円渤粤藞?jiān)果.不像轉(zhuǎn)基因食品,太空蔬菜的基因沒(méi)有變化.這意味著這些蔬菜中沒(méi)有加入新的基因.因此,它們不會(huì)損害您的健康.
解答 1.Steps 要點(diǎn)歸納題.此題所在表格后面例出的兩個(gè)小點(diǎn)都是在介紹關(guān)于確保太空蔬菜質(zhì)量的步驟,所以填step的復(fù)數(shù)形式表示步驟.
2.tested 細(xì)節(jié)理解題.由"When seeds are brought back from space,people test the seeds to make sure that the vegetables they grow will be safe to eat."可知應(yīng)該是作測(cè)試,主語(yǔ)seed是test的邏輯賓語(yǔ),所以要用被動(dòng)語(yǔ)態(tài),be動(dòng)詞are已經(jīng)給出,填test的過(guò)去分詞即可.
3.lead 細(xì)節(jié)理解題.由"They think that space vegetables might not be good for us and could give us cancer as a result of their exposure (暴露)to radiation in space."可知此題應(yīng)該用lead to cancer表示致癌,lead在情態(tài)動(dòng)詞might后用原形.
4.Advantages 要點(diǎn)歸納題.此題所在表格后面例出的三個(gè)小點(diǎn)都是在介紹太空蔬菜的優(yōu)點(diǎn),所以填advantage的復(fù)數(shù)形式來(lái)表示優(yōu)點(diǎn).
5.harm 細(xì)節(jié)理解題.由"This means that no new genes are put into the vegetables.Therefore,they won't damage your health."可知太空蔬菜不會(huì)損害人的健康,由此可知此題用no harm表示沒(méi)有傷害.
點(diǎn)評(píng) 做此類題要先快速讀一遍文章,對(duì)大意有個(gè)了解,再帶著問(wèn)題到文章中找答案,此時(shí)要注意細(xì)節(jié)的理解,還考查了歸納要點(diǎn)的能力.
