備戰(zhàn)2012，需要提前做準(zhǔn)備，酷學(xué)網(wǎng)為同學(xué)們提供小升初英語(yǔ)考試需背知識(shí)點(diǎn)，供參考。
一、a number of ,the number of
a number of 意思是“許多”，相當(dāng)于a lot of ; the number of意思是“……的數(shù)目,……的數(shù)量”，當(dāng)它作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)形式。
A number of students like playing computer games.
許多學(xué)生喜歡玩電腦游戲。
The number of the students is about 1500 in our school.
我們學(xué)校學(xué)生的人數(shù)大約是1500。
二、基數(shù)詞變序數(shù)詞助記歌。
基變序，有規(guī)律，末尾加上th;一、二、三特殊記，八加h ，九去e ，ve要用f替;以e結(jié)尾變ie，后跟th莫忘記。要想表示幾十幾，只變個(gè)位就可以。
