【简答题】
Decide whether the following statements are true or false. Write "T" for true and "F" for false: Para. 1 The author of the text, Arthur Miller, used to be an ardent but very poor farmer. He raises his root crops because they are much different from and more delicious than those bought in stores. Hot dogs are juicy and fat. Para. 2 Miller was strongly against gardening when he was rational, but he would go for gardening when he was irrational. In the sentence “The birds begin screaming hysterically, thinking what I am thinking ---- the worms are deliciously worming their way through the melting soil”, deliciously is wrongly used. Para. 3 Every year, two things send the author back to stare at that plot of soil. Para. 4 Black plastic, industrial but unrommatic, improves the soil’s composition. Para. 5 If it were not for keeping a garden, it would have been impossible for the author to learn that the earth is delicate, bountiful, and easily ruined. The author does not use a lot of chemical fertilizer because firstly he wants no waste of it, and secondly he does not want to help weeds’ growth. Para. 6 Life is sometimes pointless and difficult to grasp, and then you can go to your garden and do something there. When you are in the garden, looking at what you are raising, you feel, to some extent, that you are their father or mother. Para. 7 The author’s wife eats a large amount of vegetables every day, and that is why she is the mistress of the garden. Para. 8 His wife’s mother, an 86-year-old botanist, goes to take a first look at their garden in July. His wife's mother, always outspoken and truthful, enjoys binding the tomato plants to stakes every October. Para. 9 The author finds it hard to bear to have a fenced garden unplanted. Gardening tells the author the meaning of April and the meaning of spring. Para. 10 When April comes, the author will once again become annoyed because he is forced to start the pointless and time-consuming gardening. A garden is an extension of yourself , a battlefield where you never stop fighting. You will feel better if you are ready and willing to admit your mistakes. Gardening helps one build his character.
