-引号不是字符串中唯一可以被转义（<dfn>escaped</dfn>）的字符。 使用转义字符有两个原因：
-
-1.  首先是可以让你使用无法输入的字符，例如换行。
-2.  其次是可以让你在一个字符串中表示多个引号，而不会出错。
-
-我们在之前的挑战中学到了这个。
+引号不是字符串中唯一可以被转义（<dfn>escaped</dfn>）的字符。 Escape sequences allow you to use characters you may not otherwise be able to use in a string.

-*请注意，必须对反斜杠本身进行转义，它才能显示为反斜杠。*

-使用转义序列把下面三行文本赋值给一个变量 `myStr`。
+Assign the following three lines of text into the single variable `myStr` using escape sequences.
 
 <blockquote>FirstLine<br>    \SecondLine<br>ThirdLine</blockquote>
 
-你需要使用转义字符正确地插入特殊字符。 确保间距与上面文本一致，并且单词或转义字符之间没有空格。
+You will need to use escape sequences to insert special characters correctly. You will also need to follow the spacing as it looks above, with no spaces between escape sequences or words.
 
-**注意：**`SecondLine` 前面的空白是制表符，而不是空格。
+**Note:** The indentation for `SecondLine` is achieved with the tab escape character, not spaces.
