分析 一個人在數(shù)碼世界里一天花的時間太多時就是他/她正在失去的時候．

解答 答案：C
根據(jù)句意"一個人在數(shù)碼世界里一天花的時間太多時就是他/她正在失去的時候"可知此處強(qiáng)調(diào)的是生活在數(shù)碼世界時，他/她"正在"失去，故后面的句子該使用現(xiàn)在進(jìn)行時．綜上，本題答案為C選項(xiàng)．

點(diǎn)評 本題考查時態(tài)，做此類題目時一定要根據(jù)提示弄清句意及句子所需時態(tài)，再結(jié)合選項(xiàng)確定最終答案．

The most important part of their Christmas worship service is the love offering．This is the gift in honor of Jesus．At about 8or 9o'clock everyone makes their way to the celebration of the birthday of Jesus．Everyone who attends the service goes forward to lay down their gift upon the raised platform near the Communion table．No one will attend the service without giving a gift．

I still remember how my spoken English improved．At the beginning，I always kept
silently in the oral class to avoid to making mistakes．Before long my teacher knew
about my situation．He encouraged me to speak out that I wanted to speak．Whenever I
