Hand 有 help 幫助的意思,所以 give me a hand 或 lend someone a hand 都有助人一臂之力,幫助某人處理某事的含義。Give someone a big hand 為表演者鼓掌,表示讚賞;give one's hand to 表示答應和某人結婚。假如你對某事瞭如指掌,非常熟悉,你可以說 you know something like the back of your hand。
綠色和環保的關係最密切,城市周圍的綠化地帶叫 green belt;any political group advocating strong protection of the environment 通稱 green party 綠黨:a party member or supporter of the green party is often called a Green 綠黨成員;綠色革命是 green revolution;加拿大政界增加環保意識的過程,可以說 the greening of Canadian politics。
Good 當然是好事。Something that is good is pleasant, acceptable, or satisfactory. The comparative form is "better" and the superlative form is "best". Good 雖然是英語中最普通的一個字,但是 use and misuse of "good" for "well" 值得 ESL learners 留意。Good is never an adverb. Well is very commonly an adverb.
金與銀,同樣是金屬,待遇的差別有時會很大。奧運會金牌得主出盡風頭,銀牌健兒的成就,住往被傳媒冷落,很不公平。上屆冬季奧運會,加拿大華裔選手陳偉群獲得男子單人花樣滑冰比賽亞軍,無緣金牌,只得銀牌。網上竟然出現這段文字:Patrick Chan had the gold on a silver platter. He chose the platter。
