longerhistorythantheUnitedStates.與Chinaisoneofthe

oldestcountriesintheworld.這兩句話中分別用到了形容詞的

和

形式。當(dāng)兩者或兩部分相比較出現(xiàn)

這個(gè)詞時(shí)，用形容詞的

注意：（1）多音節(jié)形容詞、副詞的比較級(jí)前加more,最高級(jí)前加most.（2）可以用來(lái)修飾比較級(jí)的幾個(gè)詞：much/even/alittle/abit/alot練習(xí)：（1）Jimis

它……米高(長(zhǎng),寬……)。英語(yǔ)表示“有多長(zhǎng)(寬，高……)”時(shí)，一般將數(shù)詞和數(shù)量單位放在表示長(zhǎng)寬高的形容詞前作狀語(yǔ)。3.DidyouknowthatChinaisoneoftheoldestcountriesintheworld?thatChinais…是know的賓語(yǔ)從句。盡管主句的動(dòng)詞是過(guò)去時(shí)態(tài)，但由于賓語(yǔ)從句陳述的是客觀事實(shí)，所以從句仍用一般現(xiàn)在時(shí)。What’sthehighestmountainintheworld?
