Read the following paragraph and underline the topic sentence. Apart from its heavy demands on time and money, campus love, though its sincerity should not be doubted, may not be able to stand the test of time. It is relatively easy to maintain a stable relationship on campus, but upon graduation when lovers are faced with different choices—further education or job, staying at home or going abroad—they begin to pursue their respective interests. As a result, lovers may go their separate ways. According to a survey conducted by Nanjing University, 13.6% of campus lovers split up within the one or two months before graduation. Also, due to college students’ limited social contacts, the people they develop romantic relationships with are usually their classmates, schoolmates, or friends they get to know in intercollegiate activities. Once they enter society and meet more people, their idea of a good partner may change and they will probably find someone more suitable for themselves. Thus, campus love gradually perishes as time goes by.

I love sunny days because they are ideal for outings. I remember the sunny weekend when two roommates and I had a marvelous time in the old Summer Palace. Under the blue sky, the trees are bathed in golden light. On rainy days, I enjoy the sound of raindrops beating on the windowpanes. I watch the rain washing the trees and grass clean, knowing they will glitter when it clears up and hoping a rainbow will follow. In winter, a heavy snowfall offers a different type of pleasure. Cold as it often is, I always go outdoors and leave my footprints in the thick snow while throwing snowballs and making snowmen with my fellow students. A. A person should learn to be happy in all weathers. B. One’s mood should not be affected by bad weather. C. People usually prefer fine weather to severe weather. D. I enjoy both sunny weather and rainy or snowy weather. Topic sentence: _____________________________________
