Question

【題目】 Bees and butterflies are active during the daytime. They get a lot of attention for their roles as pollinators(傳粉者).But moths(蛾)aren't given the prominence they deserve.

Actually, moths are seen much less often, because they're active at night. Moth bodies often seem furry. Pollen—a yellow powder in the center of most flowers, from one flower sticks to their bodies and falls off when they move to other flowers. Scientists studied insects around nine ponds on farmlands in the United Kingdom. They visited these ponds once a month from March to October.

They studied three groups of insects: moths, bees that normally work together, like honey bees, and flying insects which work alone, such as butterflies. At the ponds, the scientists caught these flying insects and died to collect pollen from their bodies. In all, the scientists checked 838 moths, 632 other insects which work alone, and 1,548 honey bees.

By studying the pollen they collected, the scientists were able to see which plants the insects had visited. The moths had pollen from 47 different kinds of plants, including seven plants that bees don't normally visit. The honey bees had pollen from 46 different kinds of plants. The other insects that work alone had visited 45 different kinds of plants. Richard Walton, who led the study, says that bees usually choose the plants with the most nectar(花蜜)and most pollen. However, moths pollinate many different plants, filling in the gaps left by the daytime pollinators.

Not only do moths pollinate plants, they also provide important food for birds and bats.

But, like many other insects, moth numbers have dropped greatly in the last 50 years, mainly because of pesticides and the loss of natural lands. Just like bees and butterflies, moths are worth protecting. "Moths are by no means less important," says Dr. Walton.

Answer 1

【答案】

【1】C

【2】B

【3】A

【4】B

【解析】

這是一篇說明文。本文主要講述了和蜜蜂和蝴蝶相比，飛蛾作為授粉者的身份沒有受到足夠的關(guān)注。事實上它們也能為多種植物進(jìn)行授粉，而且對植物種類不挑剔。它們主要在夜間行動，因此填補(bǔ)了白天授粉者留下的空白。

【1】

詞義猜測題。根據(jù)第一段的They get a lot of attention for their roles as pollinators(傳粉者).But moths(蛾)aren't given the prominence they deserve.可知，蜜蜂和蝴蝶因為它們傳粉者的身份受到很多關(guān)注，但是蛾卻沒有被給與它們應(yīng)得的prominence。根據(jù)句意，尤其是上文的a lot of attention可猜測劃線部分的意思是“關(guān)注”。C. Concerns.(關(guān)注)符合以上說法，故選C項。

【2】

主旨大意題。根據(jù)Pollen—a yellow powder in the center of most flowers, from one flower sticks to their bodies and falls off when they move to other flowers. (花粉——大多數(shù)花中間的黃色粉末，從一朵花粘在它們的身體上，當(dāng)它們移動到其它花上時就會掉下來)可知，本段主要了對昆蟲授粉方式的研究。B. Research on insects' spreading pollen.(對昆蟲授粉的研究)

【3】

細(xì)節(jié)理解題。根據(jù)倒數(shù)第三段的Richard Walton, who led the study, says that bees usually choose the plants with the most nectar(花蜜)and most pollen. However, moths pollinate many different plants, filling in the gaps left by the daytime pollinators.(研究負(fù)責(zé)人Richard Walton說蜜蜂通常選擇有最多花蜜和花粉的植物。然而，飛蛾為許多不同的植物授粉，填補(bǔ)了白天傳粉者留下的空白)可知，和蜜蜂相比飛蛾對植物沒有那么挑剔。A. They are less choosy.(它們沒有那么挑剔)符合以上說法，故選A項。

【4】

主旨大意題。根據(jù)文章的主要內(nèi)容，可知，本文主要講述了和蜜蜂和蝴蝶相比，飛蛾作為授粉者的身份沒有受到足夠的關(guān)注。事實上它們也能為多種植物進(jìn)行授粉，而且對植物種類不挑剔。它們主要在夜間行動，因此填補(bǔ)了白天授粉者留下的空白。再結(jié)合最后一段的Just like bees and butterflies, moths are worth protecting. "Moths are by no means less important," says Dr. Walton.( 就像蜜蜂和蝴蝶，飛蛾同樣值得保護(hù)。“飛蛾也是非常重要的”Walton博士說) 可知，B. Moths Are More Vital Than We Think(飛蛾比我們想象中更重要)可以作為本文標(biāo)題，故選B項。
