Answer 1

B

試題分析：a number of一些，許多；the number of……的數(shù)目。句意：今年許多學(xué)生參加了三月十二日的植樹(shù)活動(dòng)�！�—是的，據(jù)說(shuō)學(xué)生的數(shù)目是300.結(jié)合語(yǔ)境可知前文主語(yǔ)為復(fù)數(shù)形式，故系動(dòng)詞用復(fù)數(shù)。下文主語(yǔ)number表示抽象含義，故謂語(yǔ)動(dòng)詞用單數(shù)，選B。
點(diǎn)評(píng)：由number構(gòu)成的這兩個(gè)短語(yǔ)是經(jīng)�？疾榈膶�(duì)象，其一般解題原則是先區(qū)分這兩個(gè)短語(yǔ)的含義，然后結(jié)合語(yǔ)境選擇正確答案。其結(jié)構(gòu)，含義比較固定，熟記即可。
