单选题{{B}}D{{/B}} Bananas are widely believed to grow on trees: this is incorrect. The banana is a plant which finishes all its growth in one year, reaching a height of 30 feet. Bananas have a subterranean (地下的) stem from which come large, green leaves. The plant reaches its maturity in about 18 months. As the bunches of bananas mature and the fruit develops, they can be propped (支撑) up with poles and covered with blue polyethylene (聚乙烯) bags. These prevent injury, protect against the frost, and speed ripening by increasing heat and humidity. Once the bananas plant has produced its fruit, the mother plant dies and is replaced by pups (sucker plants). {{U}}These grow next to the parent and make a new generation of banana plants.{{/U}}

单选题Where did this conversation take place?

单选题The expression "Go for it!" is a way of encouraging someone to try something. "Go for it!" means you should not worry about failure or be too careful. You should take a chance, be brave, and act firmly. "Go for it!" gets its name from football. Not football as it is played in most countries such as England, Egypt or Japan, but the kind of football played in the United States and Canada. One of the most exciting times in football comes when a team has failed, after three attempts, to move the ball forward ten yards. The team must make a critical decision. The conservative(保守的) choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed. People present are certain to shout their advice. Some will shout: "Kick the ball!" But others will encourage the team to take a chance. "Go for it!" They will scream. In the 1980s, people began using this expression in many kinds of situations to encourage someone to act bravely. There is no guarantee(保证) that the action you "go for it" will succeed. But that is the chance you take when you decide to go for it. You put your fears behind. You choose courage over safety. You hold your breath and go for it.

单选题As a girl, Louise Bethune showed great promise(前途) in planning houses and various other structures. As an adult, she was determined to become America"s first woman architect(建筑师). Young architects then usually learned their skills by working in the drafting rooms(绘图室) of professional architects. Most architects didn"t want to employ women. But Louise managed to make a well-known architect give her a chance. She worked from six in the morning to six in the evening. She wasn"t paid much. But she learned much as she worked. And her employer allowed her to use his large library. In 1881, after five years of work and study, Louise set up her own office. She advertised that "the first professional woman architect in the country was ready for business." Louise insisted that she would not be limited to design private homes just because she was a woman. She sought out a variety of jobs and designed chapels(小教堂), storage buildings, factories and schools. She did very well, inspiring other women to become architects. She often spoke out for fair treatment for women.
