Ⅱ. Complete the passage with the proper form of the expressions in Exercise I.
1.
2.
When whales come up to the sea surface, they make a "water column". It's not water—it's 3.
Plants can't walk, but 4.
Penguins swim in cold oceans, but they don't get wet. 5.
6.
1.
A black hole
is a place in space with very strong power. Nothing can get out of it if it gets too close. It is not a real "hole" but a special object.2.
Spider silk
looks thin, but it is very strong. It is 5 times as strong as steel of the same thickness. Spiders use it to make webs—flies can't break it easily.When whales come up to the sea surface, they make a "water column". It's not water—it's 3.
whales' breath
. Whales breathe air, and their warm breath turns into mist in cold air.Plants can't walk, but 4.
plant seeds
can go far. Some fly with the wind. Some stick to animal fur. Some float on water. Seeds have different "tools" to reach new places and grow.Penguins swim in cold oceans, but they don't get wet. 5.
Penguins' feathers
are thick and oily. The oil keeps water out, so penguins stay warm and dry. A penguin has more than 70 feathers on one square centimetre of skin!6.
A rainbow
is colourful in the sky. It appears when sunlight passes through raindrops. The light turns into seven colours. To see that, you need to stand with the sun behind you.答案
Ⅱ. 1. A black hole 2. Spider silk 3. whales' breath 4. plant seeds 5. Penguins' feathers 6. A rainbow
解析
【解析】
1. 根据描述“太空中有强大引力,靠近后无法逃脱的特殊天体”,可知应填A black hole。
2. 由“蜘蛛用来结网,比同厚度钢铁结实5倍”的内容,可知应填Spider silk。
3. 鲸鱼的“水柱”是其温暖呼吸遇冷形成的雾气,实际是鲸鱼的呼吸,故填whales' breath。
4. 植物不能移动,但种子可通过多种方式传播远方,所以填plant seeds。
5. 企鹅的羽毛厚实且含油脂,能防水保暖,因此填Penguins' feathers。
6. 阳光穿过雨滴形成的七色天空景观是彩虹,应填A rainbow。
