分析 文章大意:這是一篇說明文,主要講的是關(guān)于雪花的,雪花其實有不同的顏色的,在許多國家曾經(jīng)下過不同顏色的雪花,還講了雪花形成的原因.沒有兩個同樣大小或相同形狀的雪花,像頭那么大的雪花從天而降,這樣的事情曾經(jīng)在我國發(fā)生過.
解答 48.答案:B.細節(jié)理解題.根據(jù)第三段第五句When air is cold and dry,the falling snowflakes are small and hard.當(dāng)空氣寒冷干燥時,飄落的雪花又小又硬.可知,如果天氣是冷的和干燥的,雪花會又小又硬.選B.
49.答案:D.細節(jié)理解題.根據(jù)最后一段Would you be surprised to see snowflakes as big as your head falling from the sky?It occurred(發(fā)生) once in our country.It could occur again.你會驚奇地看到雪花像你的頭一樣大,從天空墜落一樣嗎?它曾經(jīng)在我們國家發(fā)生過,可能會再次發(fā)生.可知,應(yīng)該是不經(jīng)常發(fā)生這樣的事情,選D.
50.答案:A.推理判斷題.根據(jù)第二段第三句It was found that such snow was mixed with ashes (灰).This made it seem dark.Red snow has come down in other countries.When this happened,it was mixed with red dust.人們發(fā)現(xiàn)這樣的雪和灰混合在一起,這使雪花看起來很黑,在其他國家,紅色雪已經(jīng)落下,當(dāng)它發(fā)生的時候,它和紅色的灰塵混合在一起.可知,A選項"彩色雪花看起來如此,因為它們與不同顏色的灰塵混合."是正確的.選A.
點評 閱讀題型,要注重句子與句子之間、段落與段落之間邏輯關(guān)系以及對篇章的整體理解.根據(jù)所給問題選擇正確選項完成試題.
