(Question)
I'm taking a test and have to guess the right answer to the question after the article. Article: Earthquakes strike suddenly at any time of the day or night, but there's no way to tell them. If an earthquake happens, it may cause many deaths and injuries and great damage. Decide how and where your family will get together if separated. Choose an out-of-state friend or that the family members can call after the quake to report where they are and how they are. Know the safe place in each room: under the strong tables, desks, or against inside walls. Keep enough food, water and other things, including a flashlight, a radio, medicines and clothing. During the earthquake, you should keep a clear head and never be too nervous to know what to do. Protect your head and neck with your arms. If possible, take a book, a pillow or any other things to protect yourself from falling glass and ruins. If you are indoors, you must immediately lie under any strong furniture. If outdoors, move to an open area away from trees, buildings, walls and power poles. If you are in a narrow valley, move to the centre of it and look out for falling stones. If you are in a car, move to the side of the road and stop the car. Do not stop near buildings, power lines or under bridges. Stay in your car until the shaking stops. Do not move a badly injured person unless he is in great danger after the earthquake. Do not use the telephone immediately unless there is a serious injury or fire. Turn on your radio for instructions and news report. Be prepared for aftershocks. If you want to leave your home, post a message inside your home telling family members where you can be found. Question: After the earthquake, you should make sure of _ . Options: A: the phone number of your friend who lives near your home. B: the place where you can find your family. C: the time when a dangerous earthquake may happen. D: the money with which you can buy food, water and other things.

I'm taking a test and have to guess the right answer to the question after the article. Article: The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology , which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology we use, such as the silicon chips of computers. Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases. The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this "absence of evidence" is not being taken as "evidence of absence". In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods. One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle size that should concern us, but its functionality. Take gold, for example, which is a famously inert substance, and valuable because of it. It doesn't rust or corrode because it doesn't interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface... Question: What does the passage mainly focus on? Options: A: the introduction of nanotechnology and its wide use B: the present use of nanotechnology and its future C: the potential danger nanotechnology may bring us D: the proposal to stop nanotechnology due to the potential danger
(Answer)
C

I'm taking a test and have to guess the right answer to the question after the article. Article: I told my friend Graham, "I often walk two miles from my house to the town centre. Unfortunately, there is a big hill on the way." He replied, "You should say 'fortunately'." He explained that I should be glad for the extra exercise that the hill gave. I thought he was right. My attitude to the hill has now changed. As I _ the foot of the hill and prepare to climb, I tell myself that this hill will help me lose weight and get fit. This hill is my friend. I have a smile of satisfaction as I reach the top of the hill. Problems are to be faced. We cannot achieve anything with an easy life. Helen Keller once wrote that "Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened ..." Our attitude towards difficulties is of importance in life. From time to time, we all face problems, accidents and difficulties. We cannot choose the situation but we can choose our attitude toward the situation. How can you change your attitude towards difficulties? Try these steps:1. Face the problem. Do not avoid it. 2. Take a positive attitude. 3. Imagine how you will feel when you solve the problem. 4. Develop an action plan for how to deal with it. 5. Smile. Many great people like Helen Keller, took these steps to deal with their problems. They chose their attitude. They chose to be positive. They accepted the challenge. They won. Question: The author used Helen Keller's words to _ . Options: A: tell us to learn from successful people B: tell us to do more exercise to keep fit C: prove that we should choose a hard life D: prove that difficulties make a man great
(Answer)
