My favorite art course
Art courses are important at school. There are many kinds of art courses offered at our school, such as music, painting, dance, calligraphy, drama and so on. Among them, my favorite art course is painting.
I attend three painting classes a week which are held on Mondays, Wednesdays and Thursdays from 4 pm to 5 pm. During the class, I can not only paint some beautiful pictures but also watch some fun videos about famous paintings.
I enjoy painting because it brings me happiness. With my crayons, I can paint a colorful world. What's more, painting allows me to express my feelings through pictures when words fail me.
著名语言学家斯蒂芬·克拉申提出“可理解性输入假说”（the Comprehensible Input Hypothesis），即人们通过理解所听内容和所读内容，来习得语言。
他认为真正有效的语言学习需要包含以下四个要素。
①可理解，即语言内容是整体是可以理解的，即便有少数陌生的词汇也不影响全文理解。
②引人入胜的，语言材料不仅需要有趣，最好是能够达到让阅读者忘却自身是在学习语言的兴趣程度，即所谓的“心流”。
③丰富性，材料蕴含的语言信息要求是大量的、丰富的。
④渐进的，对于新的语言内容很少能够一次习得，一般需要进行重复学习。
