问题 单项选择题

关于多行结构条件语句的执行过程,正确的说法是( )。

A.各个条件所对应的语句块中,一定有一个语句块被执行

B.找到条件为True的第一个入口,便从此开始执行其后的所有语句块

C.若有多个条件为True,则它们对应的语句块都被执行

D.多行选择结构中的语句块,有可能任何一个语句块都不被执行

答案

参考答案:D

解析: If条件语句中条件成立时,就会执行相应的语句块,然后执行End If后面的代码,而不是执行If语句中所有的语句块,所以选项B)是错误的:在某些情况下,可能有多个条件为True时,只执行第1个为Ttue的条件后面的语句块,因此选项C错误;多行结构条件语句虽有多个条件,但也有可能一个条件都不成立,从而一个语句块都不执行,所以选项A)错误。

For the British, the home is a private place in which he or she goes to hide away from the troubles of life. It is very seldom that one would be invited to a British person’s home. It is rude to knock on a person’s door if you are not invited. If you are invited, don’t ask to see more than the downstairs that your British host invites you into. Never ask how much the house or any of the items in it cost.

To the American, most of them want their home to be a place where they can entertain (款待) and share their lives with their friends. They may be delighted to give you a full tour of their houses. They may also be pleased when you show your interest and pleasure in their houses.

Both British and American people will engage in quite a bit of chat and a drink or two before the meal is served. After the first mouthful, you should say how delicious the food is and ask something about it. Remember, never eat with your mouth open and make very little noise while eating. It would be nice of you to help your host in any way. Maybe offer to pour some drinks or clear up after the meal.
