44 其他需要使用現在完成時的結構　Track 044

（1）This/That/It is+序數詞+名詞+ that+現在完成時
例句
a. It is the third time that I’ve come to Beijing.
b. It is the fifth time that someone has knocked at my door.
c. —This is the tenth cup of coffee that I’ve drunk this evening.
— How are you going to be able to fall asleep later if you keep on like this?
（2）This/That/It is +最高級/ only修飾的名詞+現在完成時
例句
a. This is the most interesting movie that I’ve ever seen.
b. “Oh Jesus, you’ve got the biggest cavity（ 洞 ） that I’ve ever seen!” the dentist exclaimed as he examined a new patient. “The biggest cavity I’ve ever seen!” The patient snapped（厲聲說），“You don’t have to repeat it”. “I didn’t,” replied the dentist, “That was an echo.”
“天哪！這是我見過的最大的牙洞！”一位牙醫(yī)在給一個病人檢查時說道。“我見過的最大的牙洞！”病人厲聲說：“你也用不著說兩遍呀。”牙醫(yī)回答說：“我沒有呀，剛才那是回聲！”
c. This is the best wine I have ever drunk.
d. It is the worst book I have ever read.
e. This is the hardest job I have ever had.
f.This is the only book he has written.
注意：在上述兩種句型中，若是“It was the second/best…”，that后邊的句子則用過去完成時態(tài)。例如：
It was the fifth time that someone had knocked at my door that night.
綜上所述，現在完成時總是與現在有著密切的聯系：或表示到現在為止這一段時間“一直在延續(xù)”或“重復發(fā)生”的動作或狀態(tài)；或是表示影響現狀的事件。
