stones throw是固定短語，意為“近在咫尺。20、B 此句中Peter作動名詞sailing的所有格，本應(yīng)用Peters，但因其在動詞后作賓語，所以可用賓格，因此B為正確答案。三、主謂一致Agreement知識要點：在英語的句子中，謂語動詞的形式應(yīng)與主語的人稱和數(shù)保持一致。如何判定，那么要看句子的意思。多數(shù)情況下，根據(jù)句子的主語形式就能判定，但有的那么要看整句的意思，及強調(diào)的內(nèi)容。下面我們就常用的、易混的幾種情況作一下解釋。1、以單數(shù)名詞或代詞、不定式、動名詞短語或從句作主語時，謂語動詞要用單數(shù)形式。如：1The book is on the table.2He is reading English.3To work hard is necessary.It is necessary to work hard.4How you get there is a problem.2、復(fù)數(shù)主語跟復(fù)數(shù)動詞。如：Children like to play toys.3、在倒裝句中，動詞的數(shù)應(yīng)和它后面的主語的數(shù)一致。如以here,there開頭，be 動詞與后面第一個名詞一致。如：1There is a dog near the door.2There were no schools in this area before liberation.3Here comes the bus.4On the wall were two famous paintings.5Here is Mr Brown and his children.4、and連接兩個或兩個以上的并列主語時，謂語動詞用復(fù)數(shù)。如果主語后跟有with, together with, except, but, perhaps , like, including, as well as, no less than, more than, rather than等引起的短語，謂語動詞仍與短語前的主語的形式保持一致。如：1Jane, Mary and I are good friends.2He and my father work in the same factory.3His sister, no less than you, is wrong.4The father, rather than the brothers, is responsible for the accident.5He, like you and Xiao Liu is very diligent.6Every picture except these two has been sold.7Alice with her parents often goes to the park on Sundays.8Alice as well as her friends was invited to the concert.9Nobody but Mary and I was in the classroom at that time.5、并列主語如果指的是同一個人、同一事物或同一概念時，謂語動詞用單數(shù)，and后面的名詞沒有冠詞。如：1The writer and worker is coming to our school tomorrow.這位工人作家明天要來我們學(xué)校。2Bread and butter is their daily food. 面包和黃油是他們每日的食品。3The writer and the worker are coming to our school tomorrow.那位作家和那位工人明天將來我們學(xué)校。6、and連接的并列單數(shù)名詞前如有each, every, no, many a修飾時，謂語動詞要用單數(shù)形式。如：1Every boy and girl has been invited to the party.所有的孩子都被邀請參加這次聚會。2No teacher and no student is absent today.今天沒有教師和學(xué)生缺席。3Many a student is busy with their

please sign their names here.2Anyone who is against this opinion may speak out.3He is one of the students who were praised at the meeting.10、表示時間、距離、價格、度量衡等的復(fù)數(shù)名詞或短語作為一個整體對待時，其謂語動詞常用單數(shù)形式。如：1Three years is not a long time.2Ten dollars is what he needs.3Five hundred miles is a long distance.11、復(fù)數(shù)形式的專有名詞作為整體對待如人名、地點、國家、組織、書籍、報刊等，動詞用單數(shù)形式。如：1The United States is in North America.2The United Nations has passed a resolution(決議)。3“The Arabian Nights?天方夜譚?is an interesting book.12、有些集體名詞如family, team, group, class, audience聽眾，觀眾，government等作主語時，如看作是一個整體，謂語動詞那么用單數(shù)形式；如強調(diào)各個成員時，謂語動詞要用復(fù)數(shù)形式。如：1My family is going to have a long journey.我家要進展一次長途旅行。2My family are fond of music. 我家人都喜歡音樂。3The class has won the honour. 這班獲得了榮譽。4The class were jumping for joy. 全班同學(xué)都快樂得跳了起來。13、all, more, most, some, any, none, half, the rest等作主語時，既可表示復(fù)數(shù)意義，也可表示單數(shù)意義，謂語動詞要根據(jù)實際情況而定。如：1All of the apple is rotten. 整個蘋果都爛了。2All of the apples are rotten. 所有的蘋果都爛了。3Most of the wood was used to make furniture (家具)。14、the + 形容詞或分詞作主語時，常指一類人，謂語動詞用復(fù)數(shù)形式。如指的是抽象概念，謂語動詞那么用單數(shù)形式。如：1The young are usually very active. 年輕人通常是很活潑的。2The wounded are being taken good care of here now. 現(xiàn)在傷病員們在這里受到了很好照顧。15、or, eitheror, neithernor, whetheror, not onlybut (also)連接的是主語，謂語動詞與后一個主語一致。如：1Either you or I am going to the movies.2Not only you but also he is wrong.16、不可數(shù)名詞沒有復(fù)數(shù)形式，作主語時，謂語動詞用單數(shù)形式。如：1Water is a kind of matter.2The news at six oclock is true.17、集合名詞如：people, police ,cattle等作主語，謂語動詞用復(fù)數(shù)形式。如：1The police are searching
