If a method body has more than one expression, you must surround it with curly braces {...}. You can omit the braces if the method body has just one expression.
如果一个方法的主体包含多于一个的表达式，你必须用大括号来把它们包起来。你可以在方法主体只有一个表达式的时候省略大括号。
That alone is almost worth the price of admission if you're new to regular expressions or if you use advanced regular expression features.

Step 3: If the expression doesn't contain any more parentheses, the process of evaluation is finished.
步骤3：如果表达式中不包含其它括号，求值的过程就完成。
The WHERE clause contains two expressions that are joined by the or operator, which means that if either expression evaluates as TRUE for a specific row, that row will be deleted.
where子句包含由OR操作符联结的两个表达式，这意味着对于特定行，如果任一表达式值为TRUE，则将删除该行。

通过收下巴，你的模特可以拥有更迷人的表情，因为这样眼睛就显得大了。
If the expression contains parentheses but no operators, there is a function here that needs to be evaluated.
如果表达式包含括号，但不包含操作符，则存在需要求值的函数。
If the expression results in more than one node, then only the first node is used.
如果表达式产生多个节点，则仅使用第一个节点。
As the test man page states, the test command evaluates expression parameters and, if the expression value is True, returns a zero (True) exit value.
正如test的手册页指出的，test命令运算表达式参数的值，如果表达式的值是True，就返回零(True)退出值。
If the XPath expression contains a % sign itself, it must be escaped as specified by XML (using %).
如果XPath表达式本身包含%，则必须按xml的指定方式将其转义(使用%)。
If a single XPath expression identifies multiple nodes in a single document, they are called repeating nodes.
如果一个XPath表达式标识文档中的多个节点，它们就称为重复的节点。
If you omit the test expression, Contract4J uses reasonable defaults, depending on the context.
如果遗漏了测试表达式，Contract4J 会根据上下文使用合理的默认设置。
Otherwise, if the expression is not a constant, another macro function is called to round up the value to a power of two.
如果表达式不是常量，就调用另一个宏函数把值向上取整到2的幂。
If your expression evaluates as false and thereby triggers an assertion failure, a predefined routine called assertion_failed declared in the header file assert.hpp is executed.
如果您的表达式计算得到false，因此触发了一个断言失败，那么将执行在头文件assert . hpp中声明的一个名为assertion_failed的预定义例程。
If the XPath expression does return more than one node and you've specified XPathConstants.NODE, then evaluate returns the first node in document order.
如果XPath表达式返回了多个节点并且指定了XPathConstants . NODE，则evaluate按照文档顺序返回第一个节点。
If an XPath expression contains a percent sign itself, it must be escaped, as specified by XML (using %).
如果XPath表达式本身包含一个百分号，则必须按xml的指定方式将其转义(使用%)。
If the expression you're passing in to the parser code can't be legally constructed according to the grammar, either a ParseException or a LexicalError is thrown.
如果正在传递给解析器代码的表达式不能根据语法合法地构造，则将抛出ParseException或LexicalError。
This is because, for a given row, the XMLEXISTS predicate evaluates to false only if the XQuery expression inside returns the empty sequence.
这是因为，对于一个给定的行，只有当里面的XQuery表达式返回空序列时，XMLEXISTS谓词才为false。
Because Python requires indentation to offset the block of statements that should be executed if the expression evaluates True or False, the two print statements are both indented four Spaces.
因为Python需要缩进以错开当表达式计算为True或False时应该执行的语句块，所以两个print语句都缩进了4个空格。
The type inference picks a type that works for all outcomes of the if expression.
类型推断选择了一个满足if表达式所有结果的类型。
Since the input (domain: ananas.org) matches the regular expression. However if it is called with.
因为输入(domain：ananas.org)与该正则表达式相匹配。
The XMLEXISTS is a Boolean function that takes an XPath expression as input and returns FALSE if the XPath expression returns an empty sequence and TRUE otherwise.
XMLEXISTS是一个Boolean函数，它接受一个XPath表达式作为输入；如果这个XPath表达式返回空序列，它会返回FALSE，否则返回TRUE。
The XMLEXISTS is a Boolean function that takes an XPath expression as input and returns FALSE if the XPath expression returns an empty sequence and TRUE otherwise.
