(1)以 “a” 開頭的形容詞如alone, alike, asleep, awake等不能做前臵定語，可做表語或后臵定語。

　　(2)某些以副詞詞綴 “-ly” 結尾的詞是形容詞，如friendly, leisurely, lovely等。

　　(3)下列動詞既是實義動詞又是系動詞，注意用做系動詞時，要求形容詞做表語：remain, keep, become, get, grow, go, come, turn, stay, stand, run, prove, seem, appear, look。

　　2.考比較級時，考生應把握

　　(1)形容詞和副詞比較級的形式是否和比較連詞對應出現，即是否符合原級比較及比較級的結構。如：

　　On the whole, ambitious students are more likely to succeed in their studies than are those with little ambition.

　　(2)比較的成分是否屬于同類事物或同類概念。如：

　　Young readers, more often than not, find the novels of Dickens far more exciting than Thackeray’s.

　　(3)比較級的修飾語如 a little, a lot, the, any, even, far, hardly, lots, much, rather，還有表示倍數比較的詞等，他們的位臵是：修飾語+as…as…, 或修飾語+more…than…。如：

　　Smoking is so harmful to personal health that it kills seven times more people each year than automobile accidents.

　　(4)下列詞和短語不用比較級形式卻表示比較概念：

　　inferior，minor，senior，prior，prefer to，superior，major，junior，preferable，differ from，compared with，in comparison with，different from，rather than。如：

　　Their watch is superior to all the other watches on the market.

　　3.最高級形式應注意的問題

　　比較級形式表示最高級意義時，比較對象的范圍應用： any other +單數名詞 the other +復數名詞 the others、 anyone/anything else

　　上述詞是用來將比較級結構轉變成最高級意義的關鍵詞語，切不可遺漏，否則會造成邏輯混亂的錯誤。如不能說：John runs faster than anyone.注意與漢語表達的不同。

　　4.有關比較級的特殊句型

　　(1)not so much…as…與其說……不如說……

　　The chief reason for the population growth isn’t so much a rise in birth rates as a fall in death rates as a result of improvements in medical care.

　　(2)no/not any more…than…兩者一樣都不……

　　There is no reason they should limit how much vitamin you take, any more than they can limit how much water you drink.

　　(3)no /not any less…than…兩者一樣都……

　　She is no less beautiful than her sister.

　　(4)just as…so….正如……，……也……(用倒裝結構)

　　Just as the soil is a part of the earth, so is the atmosphere.
