1 Week 6 Thursday

Task 1：阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

(2015·浙江，C)If humans were truly at home under the light of the moon and stars，we would go in darkness happily，the midnight world as visible to us as it is to the

vast number of nocturnal(夜间活动的) species on this planet.Instead，we are diurnal

creatures，with eyes adapted to living in the sun’s light.This is a basic evolutionary

fact，even though most of us don’t think of ourselves as diurnal beings.Yet it’s

the only way to explain what we’ve done to the night：We’ve engineered it to receive

us by filling it with light.

The benefits of this kind of engineering come with consequences—called light

pollution—whose effects scientists are only now beginning to study.Light pollution

is largely the result of bad lighting design，which allows artificial light to shine

outward and upward into the sky.Ⅲ－designed lighting washes out the darkness of night

and completely changes the light levels—and light rhythms—to which many forms of

life，including ourselves，have adapted.Wherever human light spills into the natural

world，some aspect of life is affected.

In most cities the sky looks as though it has been emptied of stars，leaving behind

a vacant haze (霾) that mirrors our fear of the dark.We’ve grown so used to this orange

haze that the original glory of an unlit night—dark enough for the planet Venus to

throw shadows on Earth—is wholly beyond our experience，beyond memory almost.

We’ve lit up the night as if it were an unoccupied country，when nothing could

be further from the truth.Among mammals alone，the number of nocturnal species is

astonishing.Light is a powerful biological force，and on many species it acts as a

magnet(磁铁)．The effect is so powerful that scientists speak of songbirds and seabirds

being “captured” by searchlights on land or by the light from gas flares on marine

oil platforms.Migrating at night，birds tend to collide with brightly lit tall

buildings.

Frogs living near brightly lit highways suffer nocturnal light levels that are

as much as a million times brighter than normal，throwing nearly every aspect of their 2 behavior out of joint，including their nighttime breeding choruses.Humans are no less

trapped by light pollution than the frogs.Like most other creatures，we do need

darkness.Darkness is as essential to our biological welfare，to our internal clockwork，as light itself.

Living in a glare of our own making，we have cut ourselves off from our evolutionary

and cultural heritage—the light of the stars and the rhythms of day and night.In a

very real sense，light pollution causes us to lose sight of our true place in the

universe，to forget the scale of our being，which is best measured against the dimensions

of a deep night with the Milky Way—the edge of our galaxy—arching overhead.

【语篇解读】 本文是一篇说明文。现如今人类使夜晚充满了人造光线，使得夜晚不再黑暗，但这么做所造成的光污染的不好影响是巨大的，到了考虑这么做的后果的时候了。

1．According to the passage，human beings ________．

A．prefer to live in the darkness

B．are used to living in the day light

C．were curious about the midnight world

D．had to stay at home with the light of the moon

答案 B [细节理解题。根据第一段中的“Instead，we are diurnal creatures，with eyes

adapted to living in the sun’s light.”可知，我们人类是白天活动的动物，习惯了在日光下生活。故答案为B。]

2．What does “it” (Paragraph 1) most probably refer to?

A．The night. B．The moon.

C．The sky. D．The planet.

答案 A [代词指代题。it是代词，指代前面提到的事物，而前面提到的是night，指用来照亮黑夜。]

3．The writer mentions birds and frogs to ________．

A．provide examples of animal protection

B．show how light pollution affects animals

C．compare the living habits of both species

D．explain why the number of certain species has declined

答案 B [目的意图题。第三段谈到了光污染，后面的段落是对光污染影响的详细说明，作者3 以鸟和青蛙为例来说明光污染对动物的影响。]

4．It is implied in the last paragraph that ________．

A．light pollution does harm to the eyesight of animals

B．light pollution has destroyed some of the world heritages

C．human beings cannot go to the outer space

D．human beings should reflect on their position in the universe

答案 D [推理判断题。根据最后一段中的“In a very real sense，light pollution causes

us to lose sight of our true place in the universe...”可推断出，我们人类应该反思我们所在宇宙中的身份地位。]

5．What might be the best title for the passage?

A．The Magic Light B．The Orange Haze

C．The Disappearing Night D．The Rhythms of Nature

答案 C [标题归纳题。整篇文章都在说明光污染给生物带来的巨大影响，本来是宁静、舒适的夜晚也被人类设计的灯光所影响。所以，标题应该是The Disappearing Night。]

Task 2：用英语简要概述本文大意

答案 The passage introduces some damage light pollution causes to our daily life.

Wherever human light spills into the natural world，some aspect of life is affected.

It is time that human beings should reflect on their position in the universe.

Task 3：词汇积累

1．visible adj.看得见的
