Farms appear in citiesWhen you hear the word “farm”, you may imagine the countryside with cows and crops. But scientists say the farms of the future could be built in tall buildings in some large cities.It may be difficult to believe, but in fact, the technology for growing crops indoors already exists. Farming in the city is already happening. Some vegetables are already grown in greenhouses. Even the scientists at the South Pole research station can enjoy fresh vegetables they grow in their own greenhouse.Experts say indoor farming solves many problems. First, traditional farming takes up a lot of land. Growing crops in tall buildings—called vertical farming (垂直农业)—can solve the problem. Also, fruits and vegetables grown indoors would not face serious threats from insects and bed weather.Though vertical farms don’t exist yet, experts have created a plan for recycling in such farms. The water from indoor fish ponds would be used to water crops. Gases from crop waste would be used to heat the building. Waste from chicken or pigs would be reused as a source of energy.But experts believe vertical farming is not going to be easy. They say it can be difficult to control climate conditions indoors. Besides, plants differ in their weather and lighting needs. For example, some plants like warm, sunny weather, but other plants prefer cooler temperatures.That’s not to say these difficulties won’t be overcome—but it will take time. Most experts suggest it may take about 5 to 15 years before the first vertical farms could be created.Indoor plants need the same weather and lightning.

A good lessonAfter living in Europe for seven years, my parents decided that my family would move to the United States. We all looked forward to this. What would people think of us? For me, I hoped to be the hero of the class.I was not disappointed. All my classmates admired my experience, and I quickly became well known as “the French guy”. I was very popular for a time. However, I was not interested in many things my classmates did, and it was hard for me to connect with them. I enjoyed listening to classical music, never watch TV, and almost never watched movies.I didn’t have a common background with my friends because I grew up in Europe. I had few friends, and fewer good friends. When I look back now, I realize I was a bit of an idiot to many people around me. I kept talking proudly about my experience. And I thought myself better than those around me because I lived in Europe but they didn’t.I had decided I wanted better friends when my parents said that we were going to move again! I saw this as a perfect chance to get better friends, where people did not know of my unkind past.When we moved to California, I didn’t show off as I had done for five years. I didn’t tell everyone that I lived in Europe. I still listened to classical music, but I just kept my music to myself. Sure enough, I found that people like someone who is not typical but does not boast about it.Nothing can replace good friends, and if I had to control my temper and pride, it was well worth it.When I first moved to the US, I was very popular because of my _________.

Cosmetic Surgery Surgery that can improve the way a person looks is becoming more and more popular in the United States. This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive （有竞争力的） in their jobs. Men especially are beginning to turn to face-lifts （面部拉皮手术）, liposuction （taking fat out of the body）, and implants （putting artificial, parts into their bodies） to help them look younger. As companies downsize （缩编） and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. These operations are not without dangers, however.One young woman had an eye operation to get rid of the bags under her eyes. She described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he'd given me an injection near my eyes, I saw everything." She went on to explain, "1 knew I had to keep still because of what he was doing. He was scraping （刮） away fat underneath my eyes. It took about ten minutes. After he finished, I felt I couldn't walk. I was so faint." Her troubles did not end after the operation for two weeks. Her eyes were swollen （肿胀的） and almost completely closed, and even dark glasses could not hide the side effects of the operation.Liposuction, taking fat out of the body, is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the place where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine like a vacuum cleaner is then used to suck the fat out of the body. However, as one doctor explained, some problems can happen after the operation. He warned; "Irregular lumps and loose skin can result from this operation. If it is not evenly done, liposuction can produce a very lumpy result." Patients often must have more liposuction to correct the problem.Cosmetic surgery is more popular in the US than anywhere else.
