Plants in Desert

Only special plants can survive the terrible climate of a desert, for these are regions when the annual range of the soil temperature can be over 75C. Furthermore, during the summer there are few clouds in the sky to protect plans from the sun's ray. Another problem is the fact that there are frequently strong winds that drive small, sharp particles of sand into the plants, tearing and damaging them. The most difficult problem for all forms of plant life, however, is the fact that the entire annual rainfall occurs during a few days or weeks in spring.

Grasses and flowers in desert survive from one year to the next by existing through the long, hot, dry season in the form of seeds. These seeds remain inactive unless the right amount of rain falls. If no rain falls, or if insufficient rain falls, they wait until the next year, or even still the next. Another factor that helps these plants to survive is the fact that their life cycles are short. By the time the water from the spring rains disappears -- just a few weeks after it falls -- such plants no longer need any.

The perennials（多年生植物） have special features that enable them to survive as plants for several years. Thus, nearly all desert perennials have extensive root systems below ground and a small shoot system above ground. The large root network enables the plant to absorb as much water as possible in short time. The small shoot system, on the other hand, considerably limits water loss by evaporation.

Another feature of many perennials is that after the rainy season they lose their leaves in preparation for the long, dry season, just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation（蒸發(fā)） during the dry season. Then, in next rainy season, they come fully alive once more, and grow new branches, leaves and flowers, just as the grasses and flowers in desert do.

1. Ordinary plants are unable to survive in the desert mainly because of the changeable weather.

A Right B Wrong C Not mentioned

2. Grasses and flowers in desert are unable to survive because they stay in the form of seeds to wait for the right amount of water to come.

A Right B Wrong C Not mentioned

3. Grasses and flowers in the desert whose life cycles are short shows their ability to adapt to the quick disappearance of rainwater there after it falls in spring.

A Right B Wrong C Not mentioned

4. Winter is the toughest season for the grasses and flowers to survive.

A Right B Wrong C Not mentioned

5. The shoot system of perennials can help the plants absorb less of the sun's ray.

A Right B Wrong C Not mentioned

6. The theme of the second last paragraph is why the perennials can survive as plants for several years.

A Right B Wrong C Not mentioned

7. Desert perennials lose their leaves after the rainy season just as trees in wetter climates lose theirs in wetter climates because winter arrives, but the reasons for this features are different.

答案及解析

1． B。從文章第一段的第一句我們可以得知：因?yàn)樯衬型寥赖臏囟雀咚灾挥刑厥獾闹参锬茉谏衬锎婊?，所以不是氣候變化的原因?/P>

2． A．利用“Grasses and flowers”和“seed”作為答案線索詞，很快在第2段的第一句找到答案相關(guān)句，該句說(shuō)：沙漠里的草和花一年又一年以種子的形式度過(guò)漫長(zhǎng)，炎熱，干燥的季節(jié)?？梢?jiàn)原文的說(shuō)法與問(wèn)題句的說(shuō)法一致，所以該句正確。

3．A。該句說(shuō)：生活在沙漠里生命周期短的草和花兒顯示了它們適應(yīng)沙漠里春季降雨后雨水很快消失的環(huán)境特點(diǎn)的能力。利用“生命周期”作為答案線索詞，很快我們?cè)诘?段的最后一句中找到答案相關(guān)句，可見(jiàn)原文的說(shuō)法與問(wèn)題句的說(shuō)法一致。

4． C。利用“winter”作為答案線索詞，不難發(fā)現(xiàn)文章中并沒(méi)有提到“winter”。

5． A。利用“the shoot system”作為答案線索詞，于是在第3段的最后一句找到直接的答案相關(guān)句，該句說(shuō)：小的枝葉極大地限制了蒸發(fā)所帶來(lái)了水分的損失。可見(jiàn)原文與問(wèn)題句的說(shuō)法一致。

6． A。該題問(wèn)及倒數(shù)第2段的主題。而該段講述的是沙漠常年生植物能多年生存的原因。

7． B。利用“Lose leaves”作為答案線索詞，不難在最后一段的第一句中找到答案相關(guān)句。 該句表明它們落葉的原因是一致的：都是為了減少水分的蒸發(fā)。
