pleasant， pleased和pleasure都有“高興（的），愉快（的）”的意思，但是具體的用法卻有所區(qū)別。下面為同學(xué)們歸納它們的常見(jiàn)用法，帶領(lǐng)大家走進(jìn)“快樂(lè)”大本營(yíng)吧！

1. pleasant作定語(yǔ)時(shí)，意為“令人高興的，令人愉快的”，只能修飾事物，不能修飾人；作表語(yǔ)時(shí)，意為“使人感到高興（愉快）”，句子的主語(yǔ)只能是表示事物的詞語(yǔ)。例如：

It is a pleasant night. 那是個(gè)令人愉快的夜晚。

It is very pleasant to sit down after standing for hours. 站了幾小時(shí)后坐下來(lái)很舒服。

2. pleased通常用作表語(yǔ)，意為“高興的，欣喜的，滿意的”，其主語(yǔ)一定是人。常見(jiàn)結(jié)構(gòu)有be pleased at doing sth.， be pleased with sth.， be pleased to do sth.， be pleased + that從句。例如：

He must be pleased at this news.

他聽(tīng)到這個(gè)消息一定高興。

The teacher is very pleased with our homework.

老師對(duì)我們的作業(yè)很滿意。

The two friends were very pleased to see each other again.

這兩個(gè)朋友非常高興能再次見(jiàn)面。

使我高興的是經(jīng)理決定不再生我的氣了。

3. pleasure是名詞，表示“愉快，高興；滿意；喜歡”之意，多用于口語(yǔ)，當(dāng)你幫助他人受到對(duì)方感謝，你應(yīng)說(shuō)：Its a pleasure.或Its ones pleasure.。當(dāng)別人請(qǐng)你幫忙，你樂(lè)意幫忙時(shí)，則應(yīng)說(shuō)：With pleasure.。例如：

—Thank you for your help. 感謝你的幫助。

—Its a pleasure. 不用謝。

—Can you tell me how to use this computer？ 你能告訴我怎樣使用這臺(tái)電腦嗎？
