This week on Ask a Teacher we answer a question from Yiğitcan.
本周，我们在“请教老师”节目中回答了 Yiğitcan 的问题。
Yiğitcan asks if it is correct to begin a sentence with conjunctions such as and , but and or . Their grammar book, this person adds, says no.
Yiğitcan 询问以 and 、 but 和 or 等连词开始句子是否正确。这位人士补充说，他们的语法书说不。
It is completely acceptable to begin a sentence with the words and , but , and or . Conjunction words like these join together sentences, clauses, or phrases.
以 and 、 but 、 and or 开头的句子是完全可以接受的。像这样的连词将句子、从句或短语连接在一起。
Sometimes starting a sentence with a conjunction makes your writing sound better. It can keep your thoughts clearly separate. And it can add importance to a thought, like in this example:
有时，以连词开头的句子会让你的写作听起来更好。它可以让你的想法清晰分开。它可以增加想法的重要性，就像这个例子一样：
Stella is my sister and my best friend. But she makes a great business partner, too!
斯特拉是我的妹妹，也是我最好的朋友。但她也是一个很好的商业伙伴！
Other times, it might be better to use a different word, such as, however . The word “however” sounds a bit more formal and serious than “but.” The right word choice depends on the kind of writing you are doing.
其他时候，最好使用不同的词，例如，然而。 “然而”这个词听起来比“但是”更正式和严肃一些。正确的用词选择取决于您正在做的写作类型。
Let's look at another example. This one is from a recent Words and Their Stories article on the Learning English website . Listen for the two sentences that begin with a conjunction.
让我们看另一个例子。这是来自学习英语网站上最近的一篇单词及其故事文章。听以连词开头的两个句子。
“To make it on Broadway, you have to be very good. But you also have to be tough. Actors usually have many doors closed in their faces before other doors, hopefully, open.
“要想在百老汇立足，你必须非常出色。但你也必须坚强。演员通常会在其他门打开之前关闭许多门。希望这些门打开。
But even if you are hard-working and gifted, you may also need something else to succeed on Broadway – luck!
但即使你努力工作并且有天赋，你可能还需要其他东西才能在百老汇取得成功——运气！
Yiğitcan’s question is not surprising. Many people are taught to avoid using conjunction words at the start of sentences. In fact, experts at Merriam-Webster.com write: "Everybody agrees that it’s all right to begin a sentence with and , and nearly everybody admits to having been taught at some past time that the practice was wrong."
伊伊特詹的问题并不令人意外。许多人被教导要避免在句子开头使用连词。事实上，韦氏词典的专家写道：“每个人都同意用 and 开头一个句子是可以的，而且几乎每个人都承认过去曾被教导过这种做法是错误的。”
And that is Ask a Teacher .
