旋耕机与铧式犁在工作质量等方面有何区别?

答案

参考答案:

旋耕机是一种由动力驱动的耕整地机具,能一次完成耕、耙、平的作业。

主要用于菜地、水田的旋耕整地作业等。其优点是对土壤的适应性强,能在潮湿、粘重土壤上工作,对杂草、残茬的切碎力强。

作业后土壤松碎、平整。其缺点是消耗动力大、工效低、工作深度浅、覆盖性能差,对土壤结构的破坏比较严重。相比而言,铧式犁工作深度深,翻土性能好,对杂草、残茬的切碎能力差,但覆盖性能好。

耕翻后土壤不如旋耕后松碎、平整,土层松散、空隙大,还必须进行整地作业,才能播种。

ANGELA Chang didn’t think it would be so hard to turn singing into a career. She went to many different record companies. But the Taiwanese girl was always turned down for looking too young and small.

“I’d never had such difficulties before,” Chang said. “My confidence was smashed (粉碎) to pieces.”

Chang's talent was finally recognized in 2002. When she got a contract (合同), she burst into tears.

She soon became a star. Her first album Over the Rainbow (《飞越彩虹》) sold very well. She won many awards.

“You wouldn't believe such a powerful voice could come from such a small body,” said one musician after hearing Chang sing. “She has a special voice. You can't forget it.”

Never give up

But the 25-year-old has other talents too. Chang is also an actress. She has starred in the popular Taiwanese TV dramas, My MVP Valentine (《MVP情人》) and At Dolphin Bay (《海豚湾恋人》). Many people remember her ordinary-girl parts in the dramas.

But acting is difficult. Chang once acted so badly that she was nearly fired. Another time it took her 27 tries to get a scene right.

“I cried when I got back home,” Chang said. “But I knew that I wouldn't always fail. You only fail when you give up.”

Now with four albums behind her-Over the Rainbow, Aurora (《欧若拉》), Pandora (《潘朵拉》) and Flower in the Wonderland, it's clear that Chang and music were made for each other. As she sings in one song: “I have a pair of invisible (隐形的) wings. They fly me to the skies and give me hope.”
