what is the weather like in Autumn ? 这个句子中为什么autumn要大写？

没什么具体含义 就是指秋天的天气怎么样，如果说为什么大写 应该是强调某一地点的秋季

我很明确地告诉你：要么这本书出错了，（没可能不出错的，如果违背了原理），要么就真的是强调，或者它不注重语法的错误，，如果你学英语，是在这里抠字眼的话，是学不好的。。（专家指点）

我也想问，what为什么没有大写呢？

Capitalize this!

1.
The first word of every sentence.
2.
The first-person singular pronoun, I.
3.
The first, last, and important words in a title. (The concept "important words" usually does not include articles, short prepositions (which means you might want to capitalize "towards" or "between," say), the "to" of an infinitive, and coordinating conjunctions. This is not true in APA Reference lists (where we capitalize only the first word), nor is it necessarily true for titles in other languages. Also, on book jackets, aesthetic considerations will sometimes override the rules.)
4.
Proper nouns
Specific persons and things: George W. Bush, the White House, General Motors Corporation.
Specific geographical locations: H
