Q: Read the following article and answer the question. Article: How do you think of the following example? Many Japanese never take the vacations they should enjoy, but with the coming of "Golden Week", several holidays following one after another in late April and early May, they pour out of the country in the tens of thousands. So when traveling, whether on business or for pleasure, the first thing to think about are hotels. The kind of hotel you choose is decided according to how much money you want to spend. There are small hotels with very few services, where the prices are low, or there are large hotels with all the very latest comforts, where you could spend all the money you have in the bank for a very comfortable night. There are several different kinds of people who go to hotels. Some want to live, rather than just stay, in a hotel; hotels which are designed to meet their needs are called residential hotels. However, most people who stay in hotels are either business people or tourists on holiday. In most hotels, there are two kinds of rooms: single rooms, for the use of one person, and double rooms, for the use of two people. In addition, in large hotels, there are also suites , which include two or more rooms connected together -- perhaps a bedroom and a living room. They are for people who are very rich or very important. Question: If the president of a certain country comes, he will most probably_. Answer:

OPTIONS:
- live in a new hotel
- stay in a single room of a hotel
- stay in a double room of a hotel
- stay in a suite of a modern hotel

A: stay in a suite of a modern hotel

Q: Read the following article and answer the question. Article: An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow perched on their window. The father asked his son, "What is this?" The son replied, "It is a crow." After a few minutes, the father asked his son the 2 time, "What is this?" The son said, "Father, I have just now told you 'It's a crow'." After a little while, the old father again asked his son the 3 time, "What is this?" At this time some expression of was felt in the son's tone when he said to his father. "It's a crow, a crow, a crow." A little after, the father again asked his son the 4 time, "What is this?" This time the son shouted at his father, "Why do you keep asking me the same question again and again, although I have told you so many times 'IT IS A CROW'. Are you not able to understand this?" A little later the father went to his room and came back with an old tattered diary, which he had maintained since his son was born. On opening a page, he asked his son to read that page. When the son read it, the following words were written in the diary: "Today my little son aged three was sitting with me on the sofa, when a crow was sitting on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was a crow. I hugged him lovingly each time he asked me the same question again and again for 23 times. I did not at all feel irritated, I rather felt affection for my innocent child." Question: Why did the old father keep asking his son the same question? Answer:

OPTIONS:
- Because he developed a kind of disease.
- Because he was so boring that he wanted to play a joke with his son.
- Because he wanted to know whether his son was as patient as he used to be.
- Because his son used to love playing this game with him.

A: Because he wanted to know whether his son was as patient as he used to be.

Q: Read the following article and answer the question. Article: Cloud seeding is a method of artificially causing clouds to produce precipitation in the form of rain or snow.Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes.The effectiveness of cloud seeding remains controversial .but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production. Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II.Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane.In this form, the carbon dioxide is called dry ice.On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground. For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures.Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor.Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow.As the snow reached the warmer temperatures closer to the ground, it melted and became rain. Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide .He used particles of silver iodide because its crystal structure resembled that of ice in clouds.Silver iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature and did not require an airplane as a delivery mechanism.Instead, silver iodide crystals could be fired by cannons high into the air, where wind carried them into the clouds. Question: The best title for the passage may be " _ ". Answer:

OPTIONS:
- Cloud Seeding
- Artificial Raining
- Weather Changing
- Cloud Gathering

A: Cloud Seeding

Q: Read the following article and answer the question. Article: Charlie studied in a famous college for four years. He studied hard and did well in all his subjects. He hoped to become a good teacher. This year he left the college and began to work in a middle school. He likes his students and is strict with them. He does his best to make his classes lively and interesting. One day he carefully explained a chemical reaction to the students of Grade 2 in the chemistry lab. "Be careful, everyone," he said loudly. "Before I make the experiment,there're twenty five atoms of carbon ,but after I finish it, there're twenty four atoms of carbon left!" He stopped to watch the classroom and hoped his students would go on explaining it. But the young men looked at each other and nobody answered him. He had to ask, "What happens? What makes the atom lost?" The classroom was very quiet and none of the students looked at their teacher. "Who can tell us where it has gone?" Suddenly a soft voice came from the back row, "We did not see anybody leave the lab!" Question: The students couldn't answer Charlie's questions because _ . Answer:

OPTIONS:
- none of them had seen the atoms
- they didn't understand their teacher
- the chemical reaction was too complicated
- they all wanted to drop the subject

A:
they didn't understand their teacher
