(2)完成句子 （原創(chuàng)）
①因為缺乏興趣這次旅行被取消了。
The trip was cancelled through .

解析:(1) 選C�？疾榉衷~作狀語。his parents與lack之間呈主謂關(guān)系，所以應(yīng)用現(xiàn)在分詞作狀語；lack作動詞時不與of搭配，所以答案選C。

A. in sight B. on earth
C. at a distance D. in place
（2）完成句子 （原創(chuàng)）

(2)have lost sight of
4. require
vt. 需要；要求；命令
常用結(jié)構(gòu)：
require that+主語+(should)+動詞原形 需要某人做某事
require sb. to do sth. 命令某人做某事
require sth.（of sb.） 要求（某人）某事
I will do everything that is required of me.
凡是要求我的事，我都會辦到。
The situation requires that I（should）be there.
形勢需要我去那里。
溫馨提示
require后接賓語從句時，賓語從句必須用should do的虛擬語氣，其中should可以省略。
另外，表示“需要”，且是物作主語時，后接動詞 ?ing形式的主動形式表示被動含義，可以等于不定式被動形式；在這一點上，need和want用法相同。
The house requires mending.
=The house requires to be mended. 房屋需要維修。
All cars require servicing regularly.
所有汽車都需要定期檢修。
They required him to keep it a secret.
他們要求他對這事保密。
