請問:Cotton and rice_____grown in shanghai.用 is還是 are

熱心網友

主語中含有and 時的謂語形式1單數名詞+and+單數名詞作主語,謂語動詞用復數如   Reading,writing,and arithmetic are called the three R"s2如果由and 所連接的并列主語指的是同一個人或物時,謂語動詞用單數如A teacher and novelit is going t make a speech in the hall。但要注意下列用法中的不同A/the +單數名詞(人)+and +單數名詞(人)+單數謂語 指同一個人身兼兩種職務A/the +單數名詞(人)+and a /the +單數名詞(人)+復數謂語 指不同職務的兩個人如: The conductor and composer was greeted by a crowd of people。 the conductyor and the composer were greeted by a crowd of people。有些用and 連接起來的單數名詞,由于關系密切,已被看成一個整體,因而作主語時,謂語動詞用單數  knife and fork needle and tread a horse and carriage 3主語為every/each +單數名詞+and +every/each +單數名詞時,謂語用單數4主語為形容詞+and +形容詞+不可數名詞或復數可數名詞,并且是涉及到該名詞的品種或類別時,謂語動詞用復數如Chinese and British beer are served at the pub。指兩種用復數5當both 。。。and 。。。連接兩個單數名詞作主語時,謂語動詞用復數如 Both his brother and sister are married 。

Cotton and rice_____grown in shanghai.本題應該用“ARE”,雖然cotton 和 rice 都是不可數名詞,但是在這個句子中他們是并列的,由AND連接的,所以應用謂語復數形式。

熱心網友

兩者是并列成分,你當然應選Are

熱心網友

選 are, 因為 cotton 和 rice 是并列的兩種東西.

熱心網友

用are, 并列結構作主語時謂語用復數,例如:   Reading and writing are very important. 讀寫很重要。  注意:當主語由and連結時,如果它表示一個單一的概念,即指同一人或同一物時,謂語動詞用單數,and 此時連接的兩個詞前只有一個冠詞。例如:  The iron and steel industry is very important to our life. 鋼鐵工業對我們的生活有重要意義。
