分析 本文是一篇人物故事類短文.主要介紹了捕蠅草的功能.一個(gè)小蒼蠅移動(dòng)到了一個(gè)植物的葉子上,突然,葉子的兩部分關(guān)起來了,這個(gè)不幸的蒼蠅就出不來了,成了這個(gè)植物的食物,這就是捕蠅草.這是一種食肉植物,僅在很少的地方生長(zhǎng),比如美國(guó)北卡羅來納州的濕地.捕蠅草是不大的植物,僅長(zhǎng)的大約一英尺高,在春天的時(shí)候開白色的花,但是這個(gè)植物的葉子讓它很有趣,葉子的末端有帶小硬刺的可折疊部分,就是植物的捕捉器.捕蠅草吃什么呢?就如你看到的,它吃一些蒼蠅,像其他植物一樣,它也是通過太陽,空氣和水來制造食物,活物只是給它一些額外的營(yíng)養(yǎng)而已.這個(gè)植物怎么捕捉和吃動(dòng)物呢?捕蠅草用一種液體來吸引食物,當(dāng)蒼蠅落在張開的陷阱中的時(shí)候,小刺就會(huì)使陷阱關(guān)閉,蒼蠅飛不出去,葉子把蒼蠅壓死,然后就把它的營(yíng)養(yǎng)吸收出來,當(dāng)這個(gè)發(fā)生的時(shí)候,葉子就會(huì)變紅,大約十天以后,葉子張開,陷阱又準(zhǔn)備好了.如果你想在家里也栽一棵捕蠅草,你必須從一個(gè)專門的地方買,你不能從它生長(zhǎng)的地方拿走捕蠅草,有法律規(guī)定,不能從野外帶走捕蠅草.
解答 36.D.細(xì)節(jié)理解題.根據(jù)第三段中的"The plant has white flowers in the spring"在春天的時(shí)候開白色的花,可知它有白色的花,故選D.
37.A.細(xì)節(jié)理解題.根據(jù)第二段中的"It grows in very few places,such as wetlands near the coast of North Carolina in America."這種植物僅在很少的地方生長(zhǎng),比如美國(guó)北卡羅來納州的濕地.可知捕蠅草是生長(zhǎng)在濕地上的,故選A.
38.C.細(xì)節(jié)理解題.根據(jù)第五段中的"The Venus flytrap uses a sweet liquid (液體) to attract its food."捕蠅草用一種液體來吸引食物;根據(jù)第五段中的"When a fly lands on one of the plant's open traps,"蒼蠅落在張開的陷阱中的時(shí)候;根據(jù)第五段中的"hairs on the surface make the trap closed."小刺就會(huì)使陷阱關(guān)閉;根據(jù)第五段中的"The fly cannot get out.The leaf presses the fly until it is dead.What happens next?The plant takes in (吸收) nutrition from the food,"蒼蠅飛不出去,葉子把蒼蠅壓死,然后就把它的營(yíng)養(yǎng)吸收出來.可知蒼蠅困在陷阱里,就成了捕蠅草的食物了,因此順序是d-b-a-c,故選C.
39.B.細(xì)節(jié)理解題.根據(jù)最后一句話"There are laws about taking it out of the wild."有法律規(guī)定,不能從野外帶走捕蠅草.可知從野外帶走捕蠅草的話是違法的,故選B.
40.B.詞義理解題.根據(jù)第五段中的"The leaf presses the fly until it is dead"可知蒼蠅是被葉子擠壓死的,可知press的意思是"擠壓",故選B.
點(diǎn)評(píng) 首先仔細(xì)閱讀短文,掌握大意,然后結(jié)合具體的題目再讀短文,從中找出相關(guān)信息,就可以確定正確答案.
