在句子结构中要注意主谓一致的问题，即句子的主语与谓语动词要相呼应。要注意的有如下几点：
① 用 and 连接两个主语时一般应视为复数，但如一人身兼两职时则要用单数谓语动词形式，如：A singer and dancer is coming to our party. a singer and dancer 既歌唱又可舞的演员。
而 a singer and a dancer 则要译为：一位歌唱家和一位舞蹈家。
② 有些以 s 结尾的名词谓语动词要用单数，如：The news is good (news 为不可数名词)。
③ 有量词时应按量词的数量计算；如：This pair of glasses is good. My glasses are broken.
④ 有些形单却意为复数的名词，如：People are coming here. 这样的词还有 police，
如果要讲一个警察时，应讲 a policeman。 两个警察为 two policemen。
又如 a policewoman, two policewomen
⑤所有不定代词 each，either，neither，one，the other，nobody，nothing，anyone，anything，someone，something … 要作为单数如：Someone is waiting for you.
⑥ 英语中有一些句子要遵循就近原则，常见提示词有there be句型，either...or ， neither...nor ， not only...but also
例句：
There is a book and some pencils on the desk.
There are some pencils and a book on the desk.
⑦ 还有的句子要遵循就远原则，常见提示词有with， alone with ， together with， as well as ， besides， like， without ， except， but ， including ， rather...than，in addition to，apart from
例句：
He rather than I is right.
Tracy，like many girls，loves dancing.
