Read the following article and answer the question. Article: Smaller than your fist, your healthy heart just goes on and on. It will beat more than 60 times a minute for 70 years or more. That's something that most of us take for granted. But it's an amazing fact. 60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels . It takes you about five years to drink 2,000 gallons of water. And, unlike your knees or your back, your heart does all this work without ever complaining ! You never know that it's even there. Your heart is such a reliable "silent partner" that people forget to care for it. For many, the first indication that their heart isn't working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually. Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, "It won't happen to me. " So these people keep on smoking and drinking. They continue to eat too much meat. And their only "exercise" is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.

Read the following article and answer the question. Article: Going to sleep may seem pretty boring compared with all the fun things you do while you are awake. But there's a lot going on in your mind and body while you are sleeping. Sleep, in fact, is as important to your survival as eating and drinking. Sleep improves your mood, makes you a better athlete, and helps you remember and understand what you learned during the day. During sleep your temperature drops. Your heart rate slows. Down goes the pressure of the blood moving through your veins. A chemical that controls growth (called a hormone) moves into your bloodstream. Scientists think that sleep brings back energy and improves your immune  system. We know what happens while we're asleep because scientists study volunteers who sleep in laboratories. The sleepers are connected with machines that measure brain waves, eye movements and muscle activities. Sleep is like a school day: it's divided into different periods, or stages. When you are awake, your brain waves fire rapidly. As you begin to relax and drift into the first stage of sleep, your brain produces slower-moving waves and you lose awareness of your surroundings. As you slide to deeper sleep, your body repairs itself from the normal wear and tear of daily life. Then, as you begin to drift back up to a lighter sleep, your mind becomes more alert, and your dreams begin. You are in REM sleep. REM is the name for the rapid eye movement that happens while you are dreaming. During REM sleep, your eyes move back and forth behind your lids , as though you were watching a movie. During other stages, you might move in bed, but during REM sleep you're still. That's probably because if you could move, your body would act out your dreams. As you get close to morning, you spend more time in REM than in deep sleep, so you dream more. Researchers know that during REM sleep the part of the brain that handles learning and thinking is very active. Getting too little sleep can affect your personality. Experts recommend that children get at least nine hours sleep a night. Question: Which of the following is NOT right? Answer:
****
A: You don't move while you are in REM sleep, dreaming.

Read the following article and answer the question. Article: A farm planted levels or floors is called a vertical farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards,rather than outwards,it requires much less space than a conventional farm. The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people,all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time,food would be delivered in fresher condition and with less damage. There is a growing concern about the use of pesticides  in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space,therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics  could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course,not all food does well with this type of planting,but there are many crops that actually seem to do better. In some climates,a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words,we could grow crops in areas where we never could before. Vertical farms may just be a concept for now,but they are a concept that will solve many of our problems in the future. Question: It can be learned from the passage that vertical farms  _  . Answer:
****
A: need less room than conventional farms

Read the following article and answer the question. Article: In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.      Studies have shown. for instance. that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues( ). like plate size and lighting, have been shown to affect portion size and consumption.       A new study suggested that our shot-term memory also may play a role in appetite.  Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them --- in other words, how much they remembered eating.       This difference suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M . Brunstrom , a professor of experimental psychology at the University of Bristol.     "Hunger isn't. controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal." Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."      These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones, depending on whether the shake's label said it contained 620 0r 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.      What does this means for our eating habits? Although it hardly seems practical to trick ourselves in to eating less, the new findings do highlight the benefits of focusing on our food avoiding TV and multitasking while eating.   ... Question: What would happen at meal time if you remembered eating a lot in the previous meal? Answer:
****
A:
Answer: You would not feel so hungry.
