Question

There are 115 distinct（獨特的）species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine is 45 to 60 feet tall, but some are nearly twice as high.

Western White Pine

The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles（束）of five and produce a long cone（球果）.

Bristlecone Pine

The bristlecone pine grows slowly, reading about 20 feet tall. It is one of the oldest species of pine.

Mexican Pine

The Mexican pine can grow to 50 feet tall, with long, slender needles that drape（下垂）off it like a weeping willow（柳樹）. Often nicknamed the “willow pine”, it is native to Mexico. Its leaves can droop up to 12 inches long.

Sugar Pine

The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction.

Jack Pine

The jack pine is one of the smallest species of pine with rare leaves. Compared with the pines mentioned above, it doesn’t seem to belong to the family. It is considered a member of the scrub-pine family; it prefers sandy soil.

【解析】

試題分析: 有115種獨特品種的松樹，其中35種原產(chǎn)于北美洲。松樹常綠，是適應(yīng)性很強(qiáng)并且堅強(qiáng)的物種，在許多條件下都能生存下來。文章詳細(xì)介紹了5種不同的松樹。

1. 細(xì)節(jié)理解題。排除法。選項A，從文中第一段There are 115 distinct（獨特的）species of pine trees with 35 native to North America. 有115種獨特品種的松樹，其中35種原產(chǎn)于北美洲。故A不正確；選項C，第一段The average pine is 45 to 60 feet tall, but some are nearly twice as high.松樹的平均高度是 45 至 60 英尺高，但有些近兩倍高。故C不正確；選項D，第一段Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. 松樹是適應(yīng)性和堅強(qiáng)的生物在很多情況下都能生存下來，而其他植物不能。故可知并未說松樹通常生長在艱苦的環(huán)境中，故D不正確，故B正確。可知選B。

2. grows from Oregon to California and is often used for construction. 它從美國俄勒岡州生長到加利福尼亞，并經(jīng)常用于建設(shè)。故可知是The sugar pine. 用于建筑材料。故選C。

3. Mexican pine can grow to 50 feet tall, with long, slender needles that drape（下垂）off it like a weeping willow（柳樹）墨西哥松可以長到50英尺高，長又纖細(xì)的針狀物下垂就像垂枝的柳樹。故該種松樹有像柳樹般的針狀物，其他選項皆不正確，故選C。

4. 細(xì)節(jié)理解題。排除法。選項A，從文中第四段的介紹Its leaves can droop up to 12 inches long. 它的葉子可以下垂長達(dá) 12 英寸。并不能說明墨西哥松的葉子最長，因為其他松樹的介紹沒有都提到葉子的長度，故A不正確；選項C，從文中第五段The sugar pine is another of the large pine species, such as the bull pine, 糖松樹是另一種大型的松樹，如牛松。故C不正確；選項D，從文中第六段The jack pine is one of the smallest species of pine with rare leaves. 杰克松是最小物種之一，葉子很稀少。故D不正確；而選項B，Compared with the pines mentioned above, it doesn’t seem to belong to the family. 與上文所述的松樹相比，它似乎不屬于那個科。故B正確。故選B。

5. 主旨分析題。結(jié)合全文可知本文介紹生物物種之一，松樹的特點，以及具體介紹了五種松樹的特征等，所以可知這篇文章最可能來自于自然雜志。故選B。
