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 (粘合劑) 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(試用). 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.

In most languages, a greeting is usually followed by "small talk". Small talk means the little things we talk about at the start of a conversation. In English-speaking countries people often make small talk about the weather: "Nice day, isn't it?" "Terrible weather, isn't it?" But there is something special about small talk. It must be about something which both people have the same opinion about. The purpose of small. talk is to let both people agree on something. This makes meeting people easier and more comfortable. People usually agree about the weather, so it is a safe topic for small talk. But people often disagree about religion or politics so these are not suitable topics for small talk in English. The topics for small talk also depend on where the conversation is taking place. At football matches, people make small talk about the game they are watching: "Great game, isn't it?" At bus-stops, people may comment about the transport system: "The bus service is terrible, isn't it?"
Greetings and small talk are an important part of conversation in any language. The way people greet each other and the things they talk about, however, may be different from one language to another. This shows that there is much more to learn when we learn a language than just the vocabulary and the grammar of the language. We also have to learn the social behavior of the people who speak it.
小題1:The passage suggests that when we learn a language______.
A．we should know the culture about the country
B．we should only master the grammar and vocabulary
C．we should grasp the importance of the language
D．we should learn about the transport system of the country
小題2: When we say "Great game, isn't it?" we in fact______.
A．have a conversationB．begin a small talk
C．greet each otherD．a(chǎn)sk a question
小題3: What we learn from the passage is that______.
A．in English-speaking countries we should talk about the weather
B．different language has different grammar
C．small talk is an important part in a language
D．small talk depends on the purpose of the conversation

In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo.
The next important date in the history of photography (攝影) was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called Daguerreotype.
Soon, other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains.
In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the United States worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike (栩栩如生的).
Photography also became a kind of art by the end of the 19th century. Some photos were not just copies of the real world. They showed ideas and feelings, like other art forms.
Answer the following questions according to what you read.
小題1:Who took the first photo?  (不超過四個(gè)單詞)
小題2:The Daguerreotype was a kind of photo, wasn’t it? (不超過三個(gè)單詞)

Dukuly Dogbah, a 14-year-old Liberian(利比亞的) boy, grew up in a war. He was born in the same year the Liberian war started. Since then fighting between the government forces and the rebel armies has not stopped.
