"杯水車薪"用英語怎麼說？

“杯水車薪”，漢語成語，意思是用一杯水去救一車着了火的柴草（trying to put out a blazing cartload of faggots with a cup of water），比喻力量太小，解決不了問題。與英語習語“a drop in the bucket”意思相近。

例句：

這些捐款只是杯水車薪。

These contributions are just a drop in the bucket.

許多公司捐贈食品和藥品來幫助地震倖存者，但與所需物資相比這只是杯水車薪。

Many companies donated food and medicine to help the survivors of the earthquake, but it was just a drop in the ocean of what was needed.
