[EX Q]: Article: Not being the best but touching the limits of your ability. This belief came from my third grade teacher, the most trusted and loved person in my life. Mr. Myrus was always perfectly dressed and spoke with the conviction that talking to small kids didn't mean that he had to sacrifice proper pronunciation or grammar. And he was demanding. Oh, he wasn't unreasonable or cruel; he simply felt that no matter what your best was, you should achieve it. As luck would have it, I met him again as my eighth grade math teacher. I was not, nor ever will be, gifted in math. And thirteen-year-old girls do not have the energy to devote to something like square roots . I remember our struggles, "I don't know the answer. I can't do it.!" "Perhaps you don't know the answer," he would say quietly. "Do you think we might figure it out together? How do you know what you can do until you try?" Mr. Myrus lived around the corner, and I would often stop by to talk while he worked in his wood shop. In this room of sawdust, wood chips, and the smoke from the woodburning stove, I felt respected and valued as a person. I knew there was someone who liked me for who I was, someone who, while he always wanted me to do my best, let me know that if I had really tried, that was enough. Mr. Myrus was my teacher and my friend. He taught me to be kind. He taught me my own value. He taught me about honor, about truth, and about doing my best--and that all feelings and beliefs have dignity and deserve respect. And of all the things I know, this I believe: We can't all be "the" best, but we can, each of us, be our best, and I know that's true because Mr. Myrus told me.
Question: When did Mr.Myrus first become the author's teacher?
Options: (A) When she was eight years old. (B) When she was in the fifth grade. (C) When she was thirteen years old. (D) When she was in the eighth grade.

[EX Q]: Article: Most cultures have a feast or festival of light. Each culture celebrates this festival in a different way. The Jewish Festival of Light is called Hanukkah. It usually takes place in December. The story of why Hanukkah is celebrated is very old. It is told that a long time ago, Jewish people called the Macabees were at war with a country called Syria. On the day that the Macabees won the war, they cleaned up their holy place, which is called a temple, because the Syrian people had been living there. They wanted to light their holy lamps to say thank you for the end of the year, but found only a very small amount of oil left over to do that. The Macabees lit the lamps anyway, thinking that they would soon go out. The lamps kept burning for eight days! The Jewish people celebrate Hanukkah every year by lighting a candlestick that has eight candleholders. Every night a new candle is lit so that on the eighth night, all eight candles stand together. Presents are given at this time and money is given to the poor. The Christmas story is not quite as old as the Hanukkah story, but it is also very old. Christmas is the time when Christians around the world celebrate the birth of Jesus Christ. It is believed that Christ was born in a stable. On the night of his birth, angels, shepherds and three wise men visited him. The wise men brought gifts with them. This is a happy and busy time of the year. Homes are decorated with Christmas trees and decorations. It is a time for being with the family. Families travel long distances to gather at Christmas. Lots of lights are put up everywhere. This is to show that Jesus is the"Light of the world"who came to bring peace to all people. Lanterns are another form of light. In China, the Lantern Festival goes back to the Han Dynasty. One emperor heard that Buddhist monks would light lanterns to _ Buddha on the 15th day of the 1st lunar month;so he also ordered to light lanterns in the imperial palace and temples to show respect to Buddha on the day. Later, the rite developed into a grand festival among common people. During the festival, parks become a sea of lanterns. Sometimes streets are blocked off and lanterns are put down on each side to make a hallway of lanterns. People also hang lanterns in their gardens, outside their houses or on boats. It is believed that the lanterns will guide visitors and the spirits of ancestors to the celebrations. The Lantern Festival is a time for families to reunite.

Options: (A) The decoration of the world. (B) The wish for peace and happiness in the world. (C) Celebrating the end of the year. (D) Inviting the spirits of the ancestors to the celebration.

[EX Q]: Article: Six seconds after its launch in Virginia, US, an unmanned rocket bound for the International Space Station (ISS) exploded, disappointing people both on Earth and in space. Hundreds of millions of dollars worth of cargo was destroyed in the Oct. 28 explosion due to An"equipment failure", said Orbital Sciences, the company hired by NASA for the resupply mission. The rocket was carrying a cargo ship loaded with 2,200 kilograms of supplies such as food, tools, parts, and experiments. Roughly a third of the cargo was a series of scientific investigations. Some of them were from high school students in the US. For example, 10 students from the Cristo Rey Jesuit College Preparatory School of Houston were conducting experiments about microgravity and put their samples on the rocket. "I know that failure is a part of science, but I really feel sorry for my students," science teacher Greg Adragna told the Houston, Chronicle . Astronauts at the ISS felt a more urgent disappointment, however. The cargo included 617kg of food. Now they will have to rely on supplies from a Russian launch on Oct. 29. Launched in 1998 and involving the US, Russia, Canada, Japan, and the member countries of the European Space Agency, the ISS is one of the most ambitious international collaborations in history. Currently, there are six astronauts at the station, five male and one female. Three are from Russia, two are from the US, and one is from Germany. They have lived together for about six months. The station gets regular resupplies from Earth, using unmanned spacecrafts. Food is always a big part of the supplies. Most of the food is frozen and ready to eat, and often tastes bad-somewhat like trying to eat when you have a heavy cold. To make space life better, however, scientists have made breakthroughs. Earlier this year, Russian astronauts managed to grow a variety of crops aboard the station. Next year they are going to try to grow rice and other plants. And, as transporting water to space is expensive, astronauts are looking for ways to recycle water. "Astronauts on board the ISS already drink water distilled from sweat and urine<) ," Russian news agency RIA Novosti reported. Is that the reason the astronauts were so disappointed not to get the water from the failed resupply mission, by any chance?
