Question

【題目】Hundreds of years ago, no dandelions (蒲公英) grew in North America. Then people

came from Europe.They had dandelion seeds on their clothes. The seeds fell from their clothes onto the ground. Since then, dandelions have spread all over.

Most people believe that dandelions are weeds. They do not want them in their gardens. But some people think that dandelion flowers are pretty. And others think that dandelions taste good. They cook dandelion leaves or put them into a fresh salad. The leaves must be picked before the flowers come out or they will not taste good. Some people make dandelion flowers into wine.

Dandelions do not die easily. If the winter is not very cold, their leaves may stay green.

When the spring arrives, their flowers come out. Each night their bright yellow flowers close

up. When the sun shines the next day, they open up again. Dandelion flowers are very unusual. They do not have to get pollen (花粉) from another dandelion flower in order to form seeds. So after several days, the yellow flower turns white and soft. A tiny brown seed forms at the bottom of each white petal (花瓣). When the wind blows, the petals float away.

Each white petal carries a seed away. This lets the dandelions spread their seeds all over.

New dandelions grow where the seeds land.

【2】When is the best time to pick dandelion leaves to eat?

【解析】

這篇短文給我們介紹的是一種植物—蒲公英，包括蒲公英的歷史、人們對它的利用、它的花以及種子的形成和傳播。

【1】詞義猜測題。根據(jù)這個單詞所在的句子Most people believe that dandelions are weeds. They do not want them in their gardens.可知，人們不想在他們的花園里種植蒲公英，因為他們認為蒲公英是weeds，由此我們可以推斷，人們覺得蒲公英是不好的，因此這個詞的意思不是美麗的花、新鮮的蔬菜或綠色的樹，它的意思是“野草”，故應(yīng)選C。

【2】細節(jié)理解題。根據(jù)短文中And others think that dandelions taste good. They cook dandelion leaves or put them into a fresh salad. The leaves must be picked before the flowers come out or they will not taste good.可知，蒲公英的葉子必須在開花之前采摘，否則味道就不好了。由此可知應(yīng)選C。

【3】主旨大意題。這篇短文給我們介紹了蒲公英這種植物，第一段主要是蒲公英的歷史；第二段講述了人們?nèi)绾问褂闷压�英；第三段講述的這種植物的生命力頑強以及它的種子是如何形成和傳播的。因此A和C兩個選項都太片面，概括不了整篇文章的內(nèi)容；D選項根本在文章中沒有提到。故應(yīng)選B，“蒲公英—花還是食物？”，這個題目體現(xiàn)了文章的關(guān)鍵詞Dandelions，比較全面。

這是一篇科普說明文，給我們介紹了蒲公英這種植物。文章的主題非常明確，每一段的大意也比較清楚，整體比較容易理解。后面的題目設(shè)置有詞義猜測題、細節(jié)理解題和主旨大意題，題型比較豐富，考查較為全面。第1小題是一個詞義猜測題，往往要求我們猜測一個生詞的意思，因此我們必須從文章的上下文中尋找線索作答，把這個詞放回到原文中。因此根據(jù)這個詞所在的句子Most people believe that dandelions are weeds. They do not want them in their gardens.我們得到了這樣一個信息，大多數(shù)人呢不想在花園里種植蒲公英，可見他們對蒲公英是有偏見的，所以這個單詞不會是美麗的花、新鮮的蔬菜或是綠色的樹，所以應(yīng)該選C，野生的植物，野草。
