Shopping habits in the United States have changed greatly in the last quarter of the twentieth century. Early in the 1900s, most American towns and cities had a Main Street. Main Street was always in the heart of a town. This street was lined on both sides with many businesses. Here, shoppers walked into stores to look at all kinds of merchandise（商品）：clothing, furniture, hardware（五金）, groceries（杂货）. In addition, some shops offered services. These shops included drugstores, restaurants, shoe-repair stores, and barber or hairdressing shops. But in the 1950s, a change began to take place. Too many cars and trucks had crowded into Main Street. There were few parking places. Because the streets were crowded, merchants（商人） began to look with interest at the open spaces outside the city limits. Open space is what their car-driving customers needed．And open space is what they got when the first shopping center was built. Shopping centers, or malls, started as collection of small new stores built away from crowded city centers. Attracted by hundreds of free parking spaces, customers were drawn away from downtown areas to the outlying malls.
By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the convenience of one-stop shopping, malls were changed into landscaped parks, with beautiful flowers, fountains, and outdoor entertainment. For example, one of the shopping malls is The Galleria in Houston, Texas. Inside the Galleria, more than ten of shops face balconies and there is an indoor ice skating rink（溜冰场）. Some of Houston’s best restaurants are also here. Atop（在……顶上） the whole mammoth（巨大的） structure is a new hotel. The Galleria, and other imaginative shopping centers throughout the United States, have led a magazine to title its recent leading article “The Malling of America”.

Bamboo is one of nature's most surprising plants. Many people call this plant a tree, but it is a k 1 of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the g 2 , but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 meters （4 feet） in 24 hours! Bamboo grows almost e 3 in the world except Europe. There are more than 1,000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters（厘米） wide w 4 others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Bamboo has been used to make many things s 5 as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for h 6 of years. They often use bamboo for buildings and supporting （支撑） new buildings and bridges while they are being b 7 .
In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water b 8 they have no money, and their fields often die from no rain and no water. Bamboo pipes （管子） help poor farmers bring water to their t 9 fields without s 10 a lot of money.
It is reported that many middle school students are just not getting enough sleep, especially during the school week. The problem seems to get worse as they get older. Grade 7 students sleep 8.4 hours a school night, and Grade 9 students only 6.9 hours.
（3） It’s also reported that not getting enough sleep can cause problems in a student’s life. Many students fall asleep in school or while doing their homework, so it is not surprising that they get lower grades than those who get enough sleep.
Scientists suggest nine hours a night for middle school students. Of the students who feel unhappy and nervous, 73% don’t get enough sleep at night. Why aren’t students getting enough sleep? Many students have one of the following things, like telephone, television, or computer in their bedrooms. Using them on a school night not only takes their time away from homework, but also makes it difficult for them to fall asleep. （4） As a result, many students can't fall asleep before 11 pm, yet they must get up early to go to school the next day .
Scientists also suggest students should not do exciting activities for an hour before bedtime.
