Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes, the pieces of paper that you can fasten almost anywhere and then remove without leaving any sign that they were there, are an example of such an invention.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from a frustrating experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.
Around that time, Fry heard about a new adhesive (粘合剂) that a workmate, Dr. Spence Silver, had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough to not tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new "bookmarks" and attached it to a report he was going to give to a workmate. Soon, co-workers were asking Fry for more samples of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the "sticky pieces of paper" for trial use(试用). When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off. The invention of Post-it Notes showed that Art Fry________.

The haze（雾霾）season is back. How much do you know about haze? Haze can also be called “Smog”. The word "smog" is from the words “smoke” and “fog”, it first appeared in the early 20th century, It is a kind of air pollution（污染）caused（导致）mostly by cars and factories.
Smog will do great harm（伤害）to your health, especially lungs（肺）.It can make you cough and cause skin and eye problems. It seems that we can do nothing to stop it, but only wait until the wind blows all the smog away. However, there are some easy ways to prevent it hurting you. Here are some of them.
1. Don’t do exercise in the open.
Exercising in the open makes you breathe（呼吸）deeply, and you will take in the particles（颗粒物）deep into your lungs.
2. Stay indoors and keep the air clean.
If you can, just stay in your room and keep the doors and windows closed. Remember to air your room twice a day, you can open the window at noon or at night for half an hour.
3. Wear a mask.
Paper and cotton masks can not help you in the haze weather. Some special masks, such as N95 masks, can keep you from breathing in the particles in the air.
4. Change your diet.
Scientists find that vitamin A, C and E can greatly help protect your eyes, nose and lungs.
So eat more green vegetables and fresh fruit everyday. What’s more, do not eat food with too much fat（脂肪），it’s bad for your lungs.

It is not easy for people to sail (航海) around the world in quite small boats. Sometimes the weather gets bad. Accidents(事故) can happen easily and quickly.
One family once had an accident. A big fish swam under their boat and bit holes(洞) in it. Sea water came in and the boat soon went down. Luckily these people had another small boat——a lifeboat, so they all got into the lifeboat. They lived in the boat for many days. They ate and slept, and always hoped. At last people in a ship saved them.
How do people live in a very small lifeboat for a long time? They must be strong in every way. They must have a hope, and they must have a strong desire（愿望）to live. People cannot drink seawater. If they drink a lot of sea water, they will quickly die. They must catch rainwater and drink it. They must also catch fish and birds for food. Lifeboats do not often carry cookers. So people cannot cook their food in the lifeboats. Raw (生的) fish and birds are not very nice but they are their only food. They must eat raw food, or they will die.
| A．food | B．beds |
| C．rainwater | D．hope |
| A．their boat met bad weather |

| C．nobody knew how to sail |
| D．a fish bit holes in their boat |
A.fish and birds
B rainwater
C. both sea water and rainwater
D. both A and B
| A．It’s not interesting to sail around the world. |
| B．Fish in the sea are so dangerous. |
| C．we must have a strong desire（愿望）to live when we are in danger. |
| D．Nobody knows when we will die. |
