n.努力；努力的成果

effort指“努力”時，后面跟不定式。 His effort to reform her at length succeeded.他為改變她作出努力最后取得了成功。

effort指“作品”時，后面跟at和動名詞或名詞。 This is his effort at depicting the peasants.這是他描繪農(nóng)民的一幅作品。

effort指“努力”時，是抽象名詞，不可直接用于make后。只能以an effort，efforts，every efforts等形式出現(xiàn)；

表示相反的狀態(tài)時，用without effort或without great effort中，注意是單數(shù)effort；

effort可用于以下句型中：Effort has been made to...（不定式），Effort has been directed to...（介詞）或make special effort to...（不定式）等。

effort的基本意思是“力氣”“努力”,指做某事所使用的力氣和努力,作此解時只用作單數(shù)形式,引申表示“努力”“奮斗”,指費力做某事或艱苦的嘗試,作此解時是可數(shù)名詞。effort還可表示“努力的事例”“努力的成果”,即“作品”“成就”,為可數(shù)名詞。

effort表示“努力”時,其后可接動詞不定式作其定語,偶爾也可接介詞短語作定語。

make efforts, make an effort, make every effort后面常接動詞不定式,表示“努力做某事”,接an effort時表示“做一番努力”; 接efforts時表示“作出多次努力”,接every effort表示“每做一次努力”。
