As I wandered through the gallery, I noticed an exhibition held on the second floor，where I appreciated many outstanding paintings. Besides the paintings，there were some introductions to some famous artists. The artist who made the deepest impression on me was Van Gogh. [遮住左栏，忆加黑词汇] 我，一个艺术家爱好者，上周日参观了一家美术馆。当我漫步在画廊里时，我注意到在二楼举行的一个展览，在那里我欣赏了许多杰出的画作。除了这些绘画之外，还有一些对一些著名艺术家的介绍。让我印象最深刻的艺术家是梵高。 词汇语境串记 He worked in an art gallery when he was 16 years old. It was more than a decade later that he took art seriously, from which he drew much comfort. As he began to display a talent for painting，he realized that art was his true calling. In 1886，he began to form his own style, and employed thick, unmixed paint. However, Van Gogh's works had strong lines, as opposed to the softer edges of Impressionism. He made friends with Paul Gauguin, who shared the same vision, and they became known as Post­Impressionists. 他16岁时就在一家艺术画廊工作过。十多年后，他才认真对待艺术，并从中得到了很多安慰。当他开始展示绘画天赋时，他意识到艺术是他真正的使命。1886年，他开始形成自己的风格，使用厚重的、不混合的颜料。然而，梵高的作品有强烈的线条，与印象派较为柔和的边缘相反。他和保罗·高更成为了朋友，高更也有同样的看法，他们被称为后印象派画家。 ·be struck with/by 被……所袭击；被……所打动/迷恋…… It strikes/occurs to/hits sb that... 某人突然想起…… sth strikes/occurs to/hits sb 某人突然想到…… ·be on strike 在罢工 go on strike 举行罢工 【多维训练】　单句填空/写作迁移 (1) (strike) by the beauty of the West Lake，we stopped to admire it.
