Question: Article: After my husband died suddenly from a heart attack, my world crashed around me. My six children were all under 10, and I was burdened with the responsibilities of earning a living, and caring for the children. I was fortunate to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone. One Friday evening I came home from work to find a big pretty German Shepherd on our doorstep. This dog seemed to intend to enter the house. The children liked "German" immediately and begged me to let him in. I agreed to let him sleep in the basement. That night I slept peacefully for the first time in many weeks. The following morning we made phone calls and checked lost-and-found ads for German's owner, but with no results. On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case his owner came by, we drove off without him. When we stopped to get gas, we were amazed to see German racing to the gas station after us. No way was he going to be left behind. Monday morning I let him out for a run. He didn't come back and we were all disappointed. We were convinced that we would never see him again. We were wrong. The next Friday evening, German was back on our doorstep. Again he stayed until Monday morning, when our housekeeper arrived. This pattern repeated itself every weekend for almost 10 months. We grew more and more fond of German. We took comfort in his strong, warm presence, and we felt safe with him near us. As German became part of the family, he considered it his duty to check every bedroom to be sure each child was cozy in bed. Each week, between German's visits, I grew a little stronger, a little braver and more able to handle; every weekend we were no longer alone and enjoyed his company. Then one Monday morning we patted him on the head and let him out for what turned out to be the last time. We never saw German again. Question: The writer was _ the German Shepherd. Yes or no, is the answer "grateful to"?
Answer: Yes

Question: Article: We often find that weekends and holidays feel so short while classes and work feel so long. In reality, though, we know that this is not true. But we still wonder where that strange feeling comes from. In fact, this is one of the ways that we're tricked by time, according to the website All That Is Interesting. The website lists several wrong impressions we often have about time. Let's have a look. First of all, emotions affect our time-keeping abilities: Negative emotions, especially anxiety and boredom, make time seem longer because they make us concentrate more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of(...) time. Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was. This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details over a short period of time, which makes it seem like time is going more slowly. Another occasion when we make mistakes about time is when we take afternoon naps . Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive time again. Yes, time can be mysterious and there is no way to control it So, perhaps the best thing to do is to make good use of every minute. Question: According to the passage, in which situation do we make mistakes about time? Yes or no, is the answer "We have many problems left in the test paper, but the time is up."?
Answer: No

Question: Article: Bamboo is one of the nature's most surprising plants. Many people call this plant a tree, but it is a kind of grass. Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains. Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide _ . This plant also comes in different colors, from yellow to black to green. Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong. In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills can help to make the poor thirsty fields to be watered. Question: Which of the following is NOT true? Yes or no, is the answer "Bamboo plants are able to grow well in any part of the world."?
Answer:
No
