But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of "virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example, consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310liters of the water--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East,get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products.

This, of course, broadened my range of expression and allowed me to have a greater choice of subjects. After the first few weeks of uncertainty and awkwardness, I settled down contentedly with my new pastime. I painted every day upstairs in the back bedroom, completely by myself. I was changing. I didn't know it then, but I had found a way to be happy again and to forget some of the things that had made me unhappy. Above all I learned to forget myself. I didn't miss going out with my brothers, for I had something to keep my mind active, something to make each day a thing to look forward to. I would sit on the floor for hours, holding the brush between my toes, my right leg curled up under my left, my arms held tightly at my sides, hands clenched. All my paint and brushes were around me, and I would get Mother or Father to pin the drawing paper to the floor with tacks to keep it keep it steady. It looked like a very awkward position, with my head almost between my knees and my back crooked, but I painted all my best pictures this way, with the wooden floor as my only easel . Slowly I began to recover from my earlier depression. I had a feeling of pure joy while I painted, a feeling I had never experienced before and which seemed almost to lift me above myself. Question: According to the writer, the best thing about painting was that _ . - .it made him feel happy - it brought back sweet memories - it was easy and pleasant to learn - it could help him kill time

(Question)
Read the following article and select the best answer. Article: When a consumer finds that an item she or he bought is faulty or in some other way does not live up to the manufacturer's claims, the first step is to present the warranty, or any other records which might help at the store of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the "higher up" his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim. Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, "The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo does not work". The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and firmly as possible. If a polite complaint does not achieve the desired result, the consumer can go to a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumer's rights. Question: When a consumer finds that his or her purchase has a fault in it, the first thing he or she should do is to _ . - complain personally to the manager - threaten to take the matter to court - write a firm letter of complaint to the store of purchase - show some written proof of the purchase to the store
(Answer)
show some written proof of the purchase to the store
