题目内容

With the crazy smog going on in China, businessmen are now ready to sell people something to fight against the smog. "Smog economy" has helped certain products against the terrible weather become popular. Now let's see what we have on the list to help us through the terrible weather.

1. Masks

Well, I would say you had better stay indoors to save your lives. PM 2. 5 just increased greatly up t0 750 in Beijing recently. 3M just sold 220,000 masks of a kind. No. 1 best-selling products !

2. Air purifiers(空气净化器)

This kind of products was rarely seen in Chinese households in the past. They have become a must now. I do like these little devices, though they are expensive.

3. Oxygen inhalers(氧气吸人器)

I didn't realize oxygen inhalers also get a cut in the smog economy. As a matter of fact, your oxygen uptake has nothing to do with relieving (减轻) the bad effect of smog. It might even lead to oxygen poisoning when you inhale too much oxygen. So don't get greedy.

4. Salt lamps

Compared to oxygen inhalers, salt lamps are even worse. Some stores are selling the products at several hundred yuan , saying that they can release negative ions(离子), reduce radiation levels and purify the air. The lamps mainly contain sodium chloride. The boiling point of sodium is about 800 degrees centigrade and that of candle is 500. So how on earth can negative ions be released at only 500 degrees?

5. Plants that absorb smog

Yeah, right. Plants Vs Smog. It is scientifically justified (证明) that some plants do absorb pollutants(污染物)from the air. Many plants and calla lilies are among the best-sellers in the market. Even if they don't work, it's good to have some plants in the house anyway.

1.According to the passage, smog _ .

A. encourages people to run away from it

B. keeps people stay indoors day and night

C. gives businessmen chances to make money

D. has nothing to do with the economy

2.Salt lamps are useless, because .

A. its high boiling point may cause a big fire

B. people don't know how to increase its low boiling point

C. it may make the air even worse and dirtier

D. it actually can't give off the negative ions

3. How many products does the author think of as useful ways to fight against the smog?

A. Two. B. Three. C. Four. D. Five.

That woman carried a new blanket over her arm. Wordlessly, she gave it to me.

“Is it finished?” I asked.

She shook her head. “No. It is ready,” she replied. I handed her the money and took the blanket.

“It is beautiful, so skillfully woven(编织),” I said to my mother. “But what did she mean when she said it was not finished? How can it be ready if it is not finished?”

“I will tell you later,” my mother said, “but first I will take you to the Navajo village.”

We went down to the village. A group of young men were making sand pictures. We walked through the whole village, watching the different things the people were doing.

It was not until that evening that my mother finally explained the Navajo woman’s words.

“Did you notice anything about the things the people were making?” my mother asked.

“What should I have noticed?” I looked at her and asked.

“Each thing the Navajo make has one small part that is not complete. The designs in their sand pictures are often not perfectly done, for example---the line of a circle may not quite close. If you look carefully at your blanket, you will probably find a stitch(一针)missing.”

I took the blanket off, but it looked as perfect as any design could be. Then suddenly, I noticed that sure enough a stitch was missing!

“But why do the Navajo intentionally leave some tiny part unfinished?” I asked.

“They believe that when anything is completed or finished, it means the end has come--it will not be perfect until then. Then too, with a circle, they believe that they must leave a pathway for the bad spirits to run away and the good spirits to come in. So, often, they do not make the line close.”

A. To buy more things made by the Navajo.

B. To make friends with some of the Navajo.

C. To have a deeper understanding of the Navajo.

D. To look for the woman who sold her the blanket.

A. A stitch in time is very important.

B. Life only becomes perfect when you die.

C. He who makes no mistake is a perfect man.

D. You must always try to make your life complete.

4.What’s the main idea of the text?
