主谓一致的三大原则之逻辑一致原则 在英语句子里，谓语受主语支配，其动词必须和主语在人称和数上保持一致，这就叫主谓一致。寻其规律，大致可归纳为三个原则，即语法一致、逻辑一致和就近一致原则。高考中的单项填空题与短文改错题经常对主谓一致问题进行考查。  2. 逻辑一致：就是谓语动词的数必须和主语的意义一致，因有时主语形式为单数，但意义为复数；有时形式为复数，但意义为单数。 （1） 含all，most，half，rest等的名词词组作主语，所指的内容是复数意义时，谓语动词用复数；反之，用单数。 例： All of my classmates work hard． 我所有的同学学习都很努力。 All of the water is up now． 现在所有的水都用光了。 （2）each作主语的同位语时, 谓语动词由主语来决定,与each无关。 例如：They each have a bike. 他们每人有一辆自行车.  （3）以-ics结尾的学科名词,如politics, physics, mathematics等作主语时，谓语动词用单数。以-s结尾的名词news, works, plastics等同属此类。 例如： Politics is now taught in all schools.     现在各学校都开设政治课。 The news has got about.             消息传开了。 当以-ics结尾的学科名词表示"学科"以外的意义时，用作复数，如：mathematics（运算能力），politics(政治观点)，economics（经济意义）等 。 人教初中英语下载 新概念英语视频教程 高中英语单词大全 （4）表示时间、距离、金钱等的复数名词作主语，表达一个整体概念时,谓语动词常用单数，但若强调数量，谓语动词可用复数. 例如：Millions of people want new, simplified ways of interacting with a computer. 数以百万计的人们想要新的简化方式实现人机交互。 One million dollars is a lot of money.           一百万美元是一大笔钱.  （5）有些用来表示由两个对应部分组成一体的名词复数（trousers, glasses, shoes, shorts, scissors, scales等）作主语时，前面若有“一条”“一副”“一把”之类的单位词，动词用单数；若没有单位词或单位词是复数，则谓语动词用复数。 例如：The shoes are all right.     这些鞋子都很合适。 There is a pair of glasses on the newspaper. 在报纸上有一副眼镜。 Back to School I had always longed to get a degree, but raising a family had come first. Now with my last  1 in middle school, I thought, why not try to   2   something while I still had the opportunity. When I told my husband Bob my idea, a broad smile lit up his face. “If that’s what you   3  , we’ll make it work.”  When we asked the kids for advice, they had mixed   4  . Our daughter, already in college, thought it a great idea while John, in high school, was   5  that we might be in college at the same time. James, our youngest, wanted to know who would take him to football practice. I   6   that things would be a little different,   7   if everyone contributed, it wouldn’t be difficult.  The next day we drove to the community college and after a careful research, I chose to   8   in occupational therapy (康复理疗) . Days passed in excitement, enrolling（register） in classes, shopping for   9   and attending orientation(入学指导). I felt like a kid again, but as the first day of classes drew near, I became   10  . I was simply too old. People would laugh at me. Finally, with encouragement from my family and friends, I stuck with my   11  . As I entered my classroom that first morning, I chose a seat in the back, hoping to   12   attention. For the rest of that day, I did what I saw the other students do, and gradually, my self-consciousness（embarrassment deriving from the feeling that others are critically aware of you） faded. I found the classes and assignments   13  , and I left that day feeling I might survive. By the end of the first week, I had made a few friends. Studying and keeping up with my duties at home was  14  . No sooner would I begin to study than it was time to drive the kids to their activities. Math and science were   15   my strong subjects, so I devoted more time to those. When the first semester   16  , I had a 4.0 GPA and was placed on the Honor Roll.  1.
