lack的用法

　　I am lacking of practice or I am lacking practice.

　　BE：正常表達的方式是:

　　"I haven't given a massage for a long time. I'm out of practice."

　　If you want to use the verb "to lack":

　　"I lack practice" or I'm lacking in practice".

　　[案例4.]

　　1. Lacking money, he couldn't spend his holiday in Shanghai this summer.

　　2. Lacking in money, he couldn't spend his holiday in Shanghai this summer.

　　Q：這兩句是否都對?

　　答：1句對(lack sth.);2句錯(但語法結(jié)構(gòu)并不錯be lacking in sth.).

　　句2類似結(jié)構(gòu)的關(guān)鍵是 be lacking in + quality

　　Lacking in courage, he would never leave home.

　　Totally lacking in charm, he could not attract the audience.

　　注：However, this is still not very idiomatic. I would expect:

　　Because he was lacking in courage, he never left home.

　　[注意事項]

　　1.There is no lack of … 總用is/was單數(shù)形式

　　2.For lack of 里沒有the

　　【問題探究】 He is lack of money.

　　問：lack 是名詞，這里似乎是不能放be動詞后的吧?

　　答：That’s water.名詞有時也能用在be動詞后。這似乎有些題外了。當(dāng)然本題句是錯誤的，下面的都對：

　　1. He lacks money [lacks = verb]

　　2. He has a lack of money [lack = noun]

　　3.He is lacking in money [lacking = adjective]

　　"He is lack of money." (X)

　　"He suffers from a lack of money/confidence /personality/etc." ("Lack" = noun.) (V)

　　"I can't meet you today for lack of time." ("Lack" = noun.) (V)

　　"Lacking" 可以是adjective, 常用于be lacking in sth. 結(jié)構(gòu)。且那sth.應(yīng)該是抽象的事物，故上面的句3也錯誤了。

　　題目句是錯的。可以說: "He is lacking money" 或 "he lacks money". 如果說 "He is..." (如 "He is a teacher") 那么就是在描述他什么, 也就是他自己不能是(a lack) < he cannot himself be 'a lack'>

　　有時人們把lack用與這樣的句子，如 "He lacks common sense/initiative". 'To lack' 是個很華麗的古英語動詞, 但現(xiàn)在人們也許更可能用 "He has no...".
