Question

【題目】閱讀理解

Lack of water creates a survival problem for all desert animals.And animals can live only within a relatively narrow temperature range.For four or five months of the year，the daily temperatures in the desert may actually go beyond this range.So survival for desert animals is very difficult.

Fortunately，most desert animals have evolved (進(jìn)化) to solve the heat and water problems the desert environment creates.

Take Phainopepla, a slim black bird for example. It breeds during the relatively cool spring，then leave the desert for cooler areas.Many birds are active only at dawn and within a few hours of sunset.Some birds，such as the kingbird，continue activity throughout the day，but always fly or sit in the shade.

A few desert animals，such as the Roundtailed Ground Squirrel，sleep away the hottest part of the summer.They also hibernate (冬眠) in winter to avoid the cold season.Some desert animals such as Desert Toads，stay deep under the ground until the summer rains fill ponds. They then come out from under the ground，breed，lay eggs and supply themselves with food and water for another long period.Some smaller desert animals make a hole below the surface of the soil or sand to escape the high temperatures at the desert surface.

Certain desert lizards (蜥蝎) are active during the hottest seasons，and move extremely rapidly over hot surfaces，stopping in cooler “islands” of shade.Even their legs may be longer so they absorb less surface heat while running.

【1】How many survival problems are mentioned for desert animals in Paragraph 1 ?

A．One.

B．Two.

C．Three.

D．Four.

【2】When can we have the highest chance to see many birds in a desert?

A．In early afternoon.

B．Around midday.

C．In early morning.

D．In late morning.

【3】The Roundtailed Ground Squirrel escapes the extreme temperatures by________.

A．sitting in the shade

B．lying in a hole

C．stopping its activity

D．moving to cool habitats

【4】According to the passage，which of the following are the most active desert animals?

A．Lizards.

B．Desert Toads.

C．Phainopepla.

D．Roundtailed Ground Squirrel.

【5】What would be the best title for the passage?

A．Survival of Desert Animals.

B．Evolution of Desert Animals.

Answer 1

【答案】【1】B

【2】C

【3】C

【4】A

【5】A

【解析】【1】 細(xì)節(jié)理解題。第一段提到了沙漠動(dòng)物面臨的兩大生存問(wèn)題：缺水和溫差變化大。

【2】 細(xì)節(jié)理解題。第三段說(shuō)沙漠中的許多鳥(niǎo)類只在黎明和太陽(yáng)落山前后的幾個(gè)小時(shí)活動(dòng)，由此推知在C時(shí)間在沙漠中看到很多鳥(niǎo)兒的可能性最大。

【3】 細(xì)節(jié)理解題。通過(guò)第四段第一句可推知C正確。

【4】 推理判斷題。通過(guò)最后一段可知，蜥蜴即使是在最炎熱的季節(jié)也保持活動(dòng)，而其他三個(gè)選項(xiàng)的動(dòng)物要么是在熱的時(shí)候深藏地下，要么是遷往涼爽一些的地方。

【5】 主旨大意題。第二段是全文主題段，后文以很多沙漠動(dòng)物為例子說(shuō)明沙漠里的動(dòng)物是如何克服不利環(huán)境而生活的，故A為最佳答案。
