【小題1】B解析:
【主旨大意】
文章指出森林火災(zāi)并不像人們想象的那樣一無是處，有時(shí)候，可控范圍內(nèi)的火災(zāi)不僅無害而且還具有積極意義。比如，可控制的火災(zāi)可以使森林里的老樹、死樹燒掉，使陽光能夠照射到地面；火災(zāi)燒掉了一些種子外層包裹的厚厚的皮，并讓種子有機(jī)會(huì)得以在地面上生根發(fā)芽。
【小題1】該句意為“森林火災(zāi)會(huì)對(duì)森林引起毀壞”，damage名詞，意為“毀壞、損害”，flood名詞，意為“洪水”；illness意為“疾病”選項(xiàng)C意為“困難”，故由句意答案選C；
【小題1】由后邊的那句話可以知道“有時(shí)候森林火災(zāi)對(duì)森林系統(tǒng)還是有幫助的”，故答案選A；
【小題1】該句意為“森林火災(zāi)可以燒掉一些老樹”，get rid of意為“去掉，除去”，故選D；而選項(xiàng)A為“取代，代替……”，選項(xiàng)B是“為……做好準(zhǔn)備”，選項(xiàng)C為“對(duì)……有害處”，A、B、C均不符合題意；
【小題1】此處是指經(jīng)過火燒之后，有些種子厚厚的包衣被燒掉了，并掉到了地上，他們才有了生根發(fā)芽的機(jī)會(huì)。”故選C；A、B、D均不符合漢語意思；
【小題1】句意為“通過這種方式，森林火災(zāi)不會(huì)傳播到別的地區(qū)或者燃燒一大片森林。”cover本意為“涉及，覆蓋”，此處是指不會(huì)造成大面積的森林被燒掉；選項(xiàng)A意為“揭露，發(fā)現(xiàn)”，選項(xiàng)D為“浪費(fèi)”，都不符合題意；
【小題1】此處是指森林大火過后，即使動(dòng)物能夠生存，他們也要經(jīng)歷饑餓的折磨，“因?yàn)樯�林中的食物被大火破壞了”，故答案選C；
【小題1】此處講一段時(shí)間之后，小的植物開始生長。動(dòng)物在植物生長之后也重新回來了。“這又形成了一個(gè)(新的)食物鏈”，故答案選again，選項(xiàng)A、C、D均不符合句意 ；
