Read the following article and select the best answer. Article: Tom Brennan was working in a Philadelphia office building when he noticed a black bag. The bag contained a book. This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure - a 120-page diary kept 190 years ago by Deborah Logan, "a woman who knew everybody in her day," James Green, the librarian told the magazine American Libraries. Most of the diary is a record of big events in Philadelphia. It also includes a description of British soldiers burning Washington, D.C. in the war of 1812. She describes President James Madison on horseback as "perfectly shaking with fear" during the troubled days. George Washington, she writes, mistook her for the wife of a French man, and praised her excellent English. The adventure of the lost book began September 4 when Cory Luxmoore arrived from England to deliver the diary of his ancestor to the Library Company, which he and his wife considered to be the best home for the diary. Green told American Libraries he had the diary in his possession "about five minutes" when Luxmoore took it back because he had promised to show it to one other person. On returning to his hotel after showing the precious book to Green, Luxmoore was shocked to realize that he had left it in the taxi. Without any delay, Green began calling every taxi company in the city, with no luck. "I've felt sick since then," Luxmoore told reporters. According to Green, no one has yet learned how the diary came to the office building. Tom Brennan received a reward of $ 1,000, Philadelphia gained another treasure for its history, and Luxmoore told reporters, "It's wonderful news. I'm on high." Question: From the text, we learn that the diary is now owned by _ . - Tom Brennan - an unknown person - a Philadelphia magazine - the Library Company of Philadelphia
the Library Company of Philadelphia

Read the following article and select the best answer. Article: Scientists who discovered a new way of generating electricity from water say they may have come across an alternative source of clean energy to rival wind and solar power. The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances. The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter that contained thousands of narrow channels lined up side by side. "When we took a syringe of water and squeezed it through the filter, we got enough power to light a light bulb," said Larry Kostiuk of the University of Alberta in Canada. "The harder you push the syringe, the more electric current you get." The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface _ negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current. According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. "The last time someone came up with a way of generating electricity was Michael Faraday in 1839," he said. "So this is the first new way of generating electricity in 160 years, which is why we are so excited about it." Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. "You'd need to be sure it wouldn't... Question: What does the passage mainly want to tell us about? - A kind of solar power discovered by scientists. - A kind of new energy source found in tap water. - The breakthrough to generate electricity 160 yeas ago. - A kind of new battery invented without poisonous substances.
A kind of new energy source found in tap water.

Q: Read the following article and select the best answer. Article: The sun was just coming up when I headed out to work last May at 6 a.m. Not quite dark but dark enough to need my headlights. I turned onto one of the lonely rural country roads. Maybe it was because I was listening to the radio, maybe it was because I was already thinking about some projects at work, that I didn't spot the dark object on the road until I was too late. I ran over it and felt the back left tire pull, and then sink. I stopped and got out of the car. No mystery here---- my back left tyre was cut like a loaf of bread. Back 50 yards was a piece of sharp iron I had run over. I had never changed a tyre. I looked up the road. Not a car in either direction. The nearest service station was miles away. I threw up my hands. Then I remembered---- my cell phone! I powered it up before realizing, I didn't know who to call. Wouldn't you know it, I spotted a car coming from the opposite direction. The driver slowed as he approached. I guessed he could see I was in trouble. He stopped his car, got out and immediately saw the trouble. "Madam, would you like me to change that tyre for you?" he asked. The man couldn't have been more friendly. I was frightened out there and he put me completely at ease. "There," he said, after putting on the spare, "you are all set to go." "Good thing for me that you were driving this way," I told him, as I climbed back into my car. "Funny you should say that," he said. "Just like you, I was heading to work, but my job is in the opposite direction. I made a wrong turn at some point. I don't know what I was thinking." Question: The end of the story tells us that the man _ . - went a wrong way - felt the writer funny - didn't know what he was doing - come specially to help the writer
A: went a wrong way

(Question)
Read the following article and select the best answer. Article: Morocco, a North African kingdom, is on the south of the Mediterranean Sea and on the east of the Atlantic Ocean, between Algeria and Western Sahara. Morocco became independent from France in 1956. People in Morocco speak Arabic, which is the official language. Some people speak French and Spanish. 98.7% of the people believe in Islam. The capital city of Morocco is Rabat. Casablanca, in the north of this country, is the largest city. The famous movie Casablanca tells a story which happened in this city. It seldom rains in Morocco. The coastal cities are not cold in winter (around 16degC) and not hot in summer (around 22degC). In the inland areas, winters are colder and summers warmer. High up in the mountains the temperature can be as cold as -17.8degCin winter, and mountain tops are covered with snow most of the year. The population of Morocco is about 31,000,000. Most children in Morocco go to primary school, but only about 39% of them go to secondary school. However, this country has one of the oldest universities in the world, hundreds of years older than Oxford University. It is Al Qarawiyin University in Northern Morocco, which was founded in AD 859. Question: Which of the following word best describe the weather in Morocco? - Rainy. - Hot. - Various. - Cold.
(Answer)
Various.
