根据下列内容，回答186-190题。I've loved my mother's desk since I was just tall enough to see above the top of it as mothersat writing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I de-cided that the act of writing must be the more wonderful thing in the world. Years later, during herfinal illness, mother kept different things for my sister and brother."But the desk," she'd said a-gain, "it's for Elizabeth."I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. Butas a young girl, I wanted heart-to-heart talks between mother and daughter. They never happened.And a gulf opened between us. I was "too emotional". But she lived "on the surface".As years passed I had my own family. I loved my mother and thanked her for our happy fami-ly. I wrote to her in careful words and asked her to let me know in any way she chose that she didforgive me. I posted the letter and waited for her answer. None came. My hope turned to disap-pointment, then little interest and, finally, peace--it seemed that nothing happened. I couldn't besure that the letter had even got to mother. I only knew that I had written it, and ! could stop try-ing to make her into someone she was not.Now the present of her desk told, as she'd never been able to, that she was pleased thatwriting was my chosen work. I cleaned the desk carefully and found some papers inside--a photoof my father and a one-page letter, folded and refolded many times. Give me an answer, my letterasks, in any way you choose.

根据下列内容，回答201-205题。In the late 1960s, many people in North America turned their attention to environmentalproblems, and new steel-and-glass skyscrapers were widely criticized. Ecologists pointed out that acluster of tall buildings in a city often transportation and parking lot capacities.Skyscrapers are also lavish consumers, and wasters of electric power. In one recent year, theaddition of 17 million square feet of skyscraper office space in New York City raised the peak dailydemand for electricity by 120,000 kilowatts--enough to supply the entire city of Albany, NewYork, for a day.Glass-walled skyscrapers can be especially wasteful. The heat loss (or gain) through a wall ofhalf-inch plate glass is more than ten times that through a typical masonry wall filled with insula-tion board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapershave begun to use double-glazed panels of glass, and reflective glasses coated with silver or goldmirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise thetemperature of the surrounding air and affect neighboring buildings.Skyscrapers put a severe strain on a city's sanitation facilities, too. If fully occupied, the twoWorld Trade Center towers in New York City would alone generate 2.25 million gallons of rawsewage each year--as much as a city the size of Stamford, Connecticut, which has a population ofmore than 109,000.Skyscrapers also interfere with television reception, block bird flyways, and obstruct air traf-fic. In Boston in the late 1960s, some people even feared that shadows from skyscrapers would killthe grass on Boston Common.Still, people continue to build skyscrapers for all the reasons that they have always builtthem--personal ambition, civic pride, and the desire of owners to have the largest possible amountof rentable space.The main purpose of the passage is to__________.
