英语的And如何明确接单数、复数用法?
The fork and the knife (be) all on my desk.
The fork and knife (be) on my desk.
The poet and writer (make) us a report on Chinese literature.
The poet and the writer (make) us the reports on Chinese literature.
There (be) an apple and two oranges on my desk.
There (be) two oranges and an apple on my desk.
请帮我填了它们吧,还有and在语法书上说表示独立概念时用复数,但在There be 句中居然是就近原则优先于and的规则.
我看到别人说There is an apple and two oranges on my desk.
但语法书却说There is (are) an apple and two oranges on my desk.
好像两者皆兼用.但我真写了There are an apple and oranges on my desk.会语法错误吗?
There are an apple and oranges on my desk.
语法书说兼用，我这样写错吗？
