Q: Read the following article and select the best answer. Article: The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3%--- the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted. Now more water is needed. The problem is: Can we avoid a serious water shortage later on? First we should all learn how to save water. Secondly, we should find out the ways to _ it. Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next? The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up. ,,. Question: From the passage we learn _ . - if every city reused its water, we'll be in no danger of drying up - man can only drink and use about 25% of water on the earth - today in most large cities water is used only once - water can be used only once
A: today in most large cities water is used only once

Question: Read the following article and select the best answer. Article: We may know that there are four basic stages that human beings pass through when they enter and live in a new culture. This process, which helps us to deal with culture shock , is the way our head and our personality react to(...) the strange new things we meet with when we move from one culture to another. Culture begins with the "honeymoon stage". This is the time when we first arrive in which everything about the new culture is strange and exciting. We see new things, hear new sounds and language, eat new kinds of food. This stage can last for quite a long time because we feel we are very excited. Unluckily, the second stage can be more difficult. After we have got used to our new life, we can become very tired and begin to miss our homeland and our family, friends, pets. All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture. This time of cultural adjustment can be very difficult and lead to pulling away from the new culture. The third stage is called the "adjustment stage". This is when you begin to realize that things are not so bad in the host culture. Your sense of humor usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place. Things are still difficult, but you are now a survivor! The fourth stage can be called "at ease at last". Now you feel quite comfortable in your new place. You can deal with most problems that you have. You may still have problems with the language, but you know you are strong enough to deal with them. There is a fifth stage of culture shock which many people don't know about. This is called "reverse culture shock". Surprisingly, this happens when you go back to your own culture and find that you have changed and that things there have changed while you have been away. Now you feel a little uncomfortable back home. Life is a struggle! Question: How could the third stage be described? - Adjustment. - Pulling away - Shock. - Anger.
Answer: Adjustment.
