For them, the forbidden fruit from Eden is evil. So when Colu brought the tomato back from South America, a land mistakenly considered to be Eden, everyone jumped to the obvious conclusion. Wrongly taken as the apple of Eden, the tomato was shut out of the door of Europeans.What made it particularly terrifying was its similarity to the mandrake, a plant that was thought to have e from Hell. What earned the plant its awful reputation was its roots which looked like a dried-up human body occupied by evil spirits. Though the tomato and the man were quite different except that both had bright red or yellowfruit, the general population considered them one and the same, too terrible to touch. Cautious Europeans long ignored the tomato, and until the early 1700s most of the Western people continued to drag their feet. In the 1880s, the daughter of a well-known plant expert wrote that the most interesting part of an afternoon tea at her father's house had been the "introduction of this wonderful new fruit -- or is it a vegetable?" As late as the twentieth century some writers still classed tomatoes with mandrakes as an "evil fruit".But in the end tomatoes carried the day. The hero of the tomato was an American named Robert Johnson, and when he was publicly going to eat the tomato in 1820, people journeyed for hundreds of miles to watch him drop dead. "What are you afraid of?" he shouted. "I'll show you fools these things are good to eat!" Then he bit into the tomato. Some people fainted. But he survived and, according to a local story, set up a tomato-canning factory.1. The tomato was shut out of the door of early Europeans mainly because _______.A.it made Christians evilB.it was the apple of EdenC.it came from a forbidden landD.it was religiously unacceptable2. What can we infer from the underlined part in Paragraph 3?A. The process of ignoring the tomato slowed down.B.

To make himself a hero.B. To remove people's fear of the tomato.C. To speed up the popularity of the tomato.D. To persuade people to buy products from his factory.4. What is the main purpose of the passage?A. To challenge people's fixed concept of the tomato.B. To give an explanation to people's dislike of the tomato.C. To present the change of people's attitudes to the tomato.D. To introduce the establishment of the first tomato-canning factory.。

【语法讲解】英语Unit 5 The power of nature现在分词的用法补遗1. 现在分词的完成式一般只用作状语，不作定语。
如：The temple which has been destroyed by the earthquake will be rebuilt soon. 被地震毁坏的庙宇很快就要重建了。
误：The temple having been destroyed by the earthquake will be rebuilt soon.2. 如果现在分词表示的动作不是其逻辑主语发出的，该分词要用被动式。
现在分词的一般被动式表示一个被动的动作正在发生（如例①）；现在分词的完成被动式强调该分词表示的动作发生在谓语动词所表示的动作之前（如例②）。
如：①The problem being discussed is very important. 正在被讨论的问题很重要。
（指正在发生的被动动作）②Having been told many times, the naughty boy made the same mistake. 被告诉了好几遍，这个淘气的孩子还是犯了同一个错误。
（Having been told先于made发生）误：Being told many times, the naughty boy made the same mistake.3. 现在分词的否定式应在其前面加not。
如：①Not having been invited to the party, she was very upset. 没有被邀请去参加晚会，她很恼火。
误：Having not been invited to the party, she was very upset.②Not seeing my brother, I asked my mother where he was. 由于没有见到我弟弟，我便问妈妈他在哪里。
