Read the following article and answer the question. Article: Pan Aiying, a Chinese teacher at Wutou Middle School in Qihe County, in East China's Shandong Province, didn't think her text messages would help to get her belongings back. A young man riding a motorcycle robbed her of her bag, in which there was her mobile phone, bank cards and 4,900 yuan, as she was riding her bicycle home on Saturday evening. Pan said at first she considered calling the police, but then decided to try to persuade the young man to return her bag. Pan called her lost phone with her friend's, but couldn't get through. So she began sending messages. "Hey, I'm Pan Aiying, a teacher from Wutou Middle School. You must be going through a difficult time. If so, I will not blame you. " Wrote Pan in her first text message, which got no answer. "Keep the 4,900 yuan if you really need it, but please return the other things to me. You are still young. To make mistakes is human. Correcting your mistake is more important than anything. " Pan wrote in another message. She gave up hope after sending 21 text messages without any answer and planned to call the police the next morning. However, as she left her home on Sunday morning, Pan found her stolen bag lying in the courtyard. Nothing was lost. "Dear Pan: I am sorry. I made a mistake. Please forgive me. You are so kind even though I stole from you. I'll correct my ways and be an honest person," said a letter left with the bag. Question: Where was Pan Aiying robbed? Answer:
OPTIONS:
- In the school.
- At home.

Answer: In the street.

Read the following article and answer the question. Article: It is easy for us to tell who our family members are, but do plants recognize their own family? Some do, scientists say, according to a report by Science News in early 2010. Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either _ or strangers. When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough. When jewelweed seedlings were planted with siblings, they grew a few more branches than they usually would if they were alone - but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete. According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach - where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water - so when they're threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves. Question: In the text, the writer mentioned the experiments of Jewelweeds to _ . Answer:
OPTIONS:
- make a comparison
- introduce a topic
- describe a pretty flower
- build a new theory

Answer: introduce a topic

Read the following article and answer the question. Article: It was a bright Saturday morning. I stopped at a cafe to enjoy a cup of coffee and read the morning newspaper. Suddenly, I felt a hand on the back of my jacket and heard someone say, "Hey Steve! How are you doing?" Looking back, I saw a man. He looked familiar, but I couldn't remember where we had met. The young man also held a cup of coffee, so I asked him to join me. Very soon, his story began to _ my memory. Five years earlier, Johnson was traveling home late on a February night. A heavy snow had arrived that afternoon, and by midnight, the snowdrifts were getting deep. His car was stuck in a snowdrift just down the road from my house. He walked to my house for help. I helped him pull his car out of the snowdrift and up to the street where the snow had been cleaned away. This was a normal happening here during the winter. I couldn't count the times someone has helped me to pull my car from a snowdrift. However, it was an unforgettable experience for him. He was only eighteen at that time, and he said he was very afraid. No one wants to be stuck in a snowdrift at night. Sometimes, one simple kindness at the right moment can change the direction of a life. So, be kind and helpful. Question: Where did Steve meet Johnson for the first time? Answer:
OPTIONS:
- At a cafe.
- At Steve's house.
- At a bus station.
- On a street.

Answer:
At Steve's house.
