This is a great opportunity. We can't afford to hang back.(這是個絕好的機會。我們可不能再猶豫了。)

If you hang back, and reserve and criticise at first, you are preventing yourself from getting the fullest possible value from what you read.(如果讀書伊始便固步自封、處處設防，甚至批評挑剔，那么你就無法盡可能地從閱讀中獲得最大的價值。)

If you are making a long distance call on a public telephone and run out of money, give the number on your phone to the person you're talking to. Then hang up the receiver and he can call you back.(如果你用公共電話打長途，錢花光了，把你的電話號碼給你正在通話的人，然后掛上電話，他會給你回電話的。)

If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read.(倘若你未開卷便先行猶豫退縮，說三道四，你絕不可能從閱讀中最大限度地獲取有用價值。)

Do I hang back and crawl through the remaining 52 turns at their speed?(我是否該退幾步，跟著它們，以爬行般的速度緩緩駛過剩下的52個大彎？)

Meanwhile, I would hang back on the periphery, already school aged and of no interest.(另一邊是我退到了邊緣，已經到了上學的年齡卻毫無興趣。)

China's disinclination to rush to the gates of Space Exploration has likewise been a preference to hang back and see what happens first, rather than make costly mistakes by precipitous action.(中國不急于太空探索之門也同樣是一個原因，先看看會發生什么，而不是讓魯莽的行動導致發生代價高昂的錯誤。)

I saw him step forward momentarily but then hang back, nervously massaging his hands.(我看到他向前走了片刻，然后卻退縮不前，忐忑不安地搓著手。)

Hang my coat back, I'm not going now.(請把我的大衣掛回去，現在我還不想走呢。)

Before realizing this, I'd hang back and listen to everyone, and take everything in, but sometimes go ten minutes or more without uttering a word.(在認識到這一點之前，我畏縮不前，傾聽每個人的高談闊論，接納他們所說的一切，有時連續十分鐘(甚至更久)一言不發。)
