The future is worth looking forward to.The future is worthy of being looked forward to.It is worthwhile looking forward to the future.注意，worth为介系词，后面可以用动名词作宾语，动名词用主动形式表示被动的意义，如：Whatever is worth doing at all is worth doing well.This book is worth reading.It is worthwhile reading the book.It would be worth his while helping the foreigner.希望我能帮助你解疑释惑。
