四、阅读单选

There's much to see under the sea, but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out to touch something and completely missing it.

Objects under water will appear larger than they would on the surface, too. Be careful not to tell any stories about the big fish that got away. That fish might not be so big after all! It's just because sometimes things can seem to be as much as about 33 percent bigger in water!

What's more, in deeper water, colors just don't seem as bright. In fact, it looks as if some colors are missing. Remember the color of an object results from the wavelengths（波长）of light that are reflected（反射）from its surface. And light is taken in as it moves down through the water.

Swimmers wear wet suits to keep warm underwater. Let's take a bright red, yellow, and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths, the longest among these three colors, are missing. As you go down deeper, the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater, you will look terrible, like a ghost（鬼怪）! And you have to wait for your return to the surface to enjoy the bright colors again!

22．You miss the object underwater when you want to touch it because        .

A．your eyesight is quite poor B．you are not quick enough

C．it is not as close as it seems D．it disappears very quickly

23．The example of the wet suit is used to explain the change of         of an object underwater.

A．the size B．the color C．the position D．the weight

24．The underlined word “descend” probably means         in Chinese in this passage.

A．上升 B．漂浮 C．屏息 D．下潜

25．Which of the following is TRUE?

A．A four-meter-long fish looks three meters long underwater.

B．The wavelengths of red light are longer than those of blue light.

C．Much water will be taken in by the swimmer deep in the water.

D．You will see a ghost if you go as deep as 6 to 9 meters into the sea.

26．The best title of this passage is        .

A．The Standard of Color Underwater B．The Direction of Light Underwater

C．The Brightness of Color Underwater D．The Behavior of Light Underwater

五、阅读补全句子

阅读下面短文，根据文中信息完成一张海报。每空限填三词。

Doing “Clean” Exercise

When you go for a run outside, chances are that you'll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging.

The word “ plogging” is the Swedish phrase “plocka upp”（pick up）and the English word “Jogging”（running slowly）put together.

What a plogger needs is a rubbish bag and a pair of gloves to protect your hands. While collecting rubbish, ploggers learn to classify（分类）and deal with it correctly, too.

Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise. For example, a 30-minute plogging burns around 288 calories（卡路里）, compared to 235 calories burned from just jogging.

So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way? Your body and the environment will thank you.
