夏天，為大地帶來雨水。 （Summer always brings rain.） 疏導雨水，需要暢通的渠道。 （To carry away rainwater, our drains must be kept clear.） 但當遇到隨處拋棄的垃圾、建築廢料和油污，淤塞的渠道就會為我們帶來煩惱。 （Sometimes, however, because of inconsiderate disposal of rubbish, construction waste or grease, blocked drains can cause trouble.） 渠道暢通，有你幫手，必定會成功。 （We need your help to keep our drains clear.）
