I'm taking a test and have to guess the right answer to the question after the article. Article: Monty Hempel is a professor of environmental sciences at Redlands University in California. He studies ecological literacy--or ecoliteracy, for short. Ecoliteracy is the ability to think about and understand the natural processes that make life possible. Monty Hempel says ecoliteracy gives people knowledge about environmental problems. But he says it does not always work to get them to change their behavior. Mr. Hempel wrote part of the Worldwatch Institute's latest State of the World report. He says in his article, "Some people think that ecoliteracy is just a green form of science literacy. And what I have tried to ask is whether that's enough. In other words, what an ecologically-literate person needs to know might include things like the cycles and the flows, the energy systems, all of those kind of things that we would call the science of ecology. " "That doesn't seem to lead to action to protect our environment--to protect our life-support system to the level that we need to. Just because we know a lot about the environment doesn't mean that we actually act to save it. After all, actions speak louder than knowledge. " He adds that people may not be very worried about environmental problems if they seem far away. "Some people call it psychological distance. A lot of climate issues are worse in the Arctic and most of us don't spend time in the Arctic. And so, there's a certain distance. But there's also a distance that's happening in the world as it urbanizes--people spending more time in front of screens and less time out in nature. We become, if you will, disconnected from the natural systems that used to be the key to success for a human being. " To help children discover the wonders of nature, he adds that children should learn about nature in school. But he also points out we have a high mountain for people to climb from knowledge to action. Question: Mr. Hempel thinks people show no concern about some environmental problems because _ . Options: A: they lack knowledge on environment protection B: they have no awareness of environment protection C: some environmental problems are not worse at all D: some environmental problems happened far away

I'm taking a test and have to guess the right answer to the question after the article. Article: Listening test is one of the most important parts of the English exam. Here are some tips for you. Before you start to listen, you need to relax. Don't be stressed out. And try to read the questions. These questions usually help you understand the conversation or the passage. Then listen carefully to the first sentence. It usually tells you the main idea of the passage. When you're listening, try to do some thinking and take some notes, such as: What happened? When, where, and how? What does the speaker want to tell us? In this way, you may understand the passage better. Please remember not to think about one or two words for a long time. When you hear some words you don't know, don't spend too much time on them. Very often, you'll find out what they mean later when you go on with the listening. Question: We should listen to the first sentence carefully, because it usually tells us _ . Options: A: the answers to the questions B: where to write the answers C: the main idea of the passage D: how much time left for the listening test

I'm taking a test and have to guess the right answer to the question after the article. Article: The immune system is the body's defender. It identifies, tracks down, and destroys troublemakers before they can hurt the body. Those troublemakers may be, for example, bacteria from a cut or splinter, a measles germ, a cold bug, or even a cancer cell. These invaders try to take over our tissues and feed off our bodies' nutrients. If they succeed, we become sick or, sometimes, even die. It's the job of our immune systems to destroy these invaders before they destroy us. Say you picked up a flu virus last week. Perhaps it entered your body through a cut, from a drinking glass, or from the air you breathe. Of course, you didn't feel it, but the virus made its way into your bloodstream. As soon as it entered your body, it began to reproduce. Viruses have only one goal: to take over your cells. Once inside your body, viruses try to enter cells and disrupt their normal work. If left alone, these viruses would hurt so many cells that you would weaken, or worse, get a serious illness. But this flu virus should not be so complacent as it seems to be. As it reproduces in your bloodstream, the virus is met by a certain kind of white blood cell, the lymphocytes. The _ are the foot soldiers that keep you alive. The number of lymphocytes in your body is hard to imagine. Thousands of them could fit in the period at the end of this sentence. Your body holds about a trillion --that's 1,000,000,000,000 of them, or about 3,000 in every drop of blood. _ Some of these lymphocytes pass through a small walnut-sized organ called the thymus. The thymus is the base of the neck. Here, special hormones turn lymphocytes into fighting cells, called T cells. T cells have one terrific talent: They can tell the difference between friend and foe; what should be in our bodies and what shouldn't. They do not affect the body 's healthy cells. Yet they attack everything that is foreign to our bodies, such as germs, transplants, and even our own cells which have become abnormal, as in the case of cancer. Question: Which of the following questions best summaries the main idea of the whole passage? Options: A: How does the immune system attack the flu virus? B: How do the lymphocytes work in our body? C: How does the immune system function in our body? D: What is the so-called immune system?
