C. Lacking D. lacked in
(2)完成句子 （原創(chuàng)）
①因?yàn)槿狈εd趣這次旅行被取消了。
The trip was cancelled through .
②他缺乏信心。
He .
解析:(1) 選C�？疾榉衷~作狀語(yǔ)。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(yǔ)；lack作動(dòng)詞時(shí)不與of搭配，所以答案選C。
(2)①lack of interest ②lacks confidence
3. sight

（2010?01?陜西商洛檢測(cè)）
A. in sight B. on earth
C. at a distance D. in place
（2）完成句子 （原創(chuàng)）
我們失去了許多珍貴的動(dòng)物。
We several precious animals.
解析:(1) 選A。in sight為固定搭配，意為“看得到”；on earth用在疑問(wèn)句或否定句中，用來(lái)加強(qiáng)語(yǔ)氣，意為“究竟；到底”；at a distance意為“在遠(yuǎn)處”。
(2)have lost sight of
4. require
vt. 需要；要求；命令
常用結(jié)構(gòu)：
require that+主語(yǔ)+(should)+動(dòng)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(huì)辦到。
The situation requires that I（should）be there.
形勢(shì)需要我去那里。
溫馨提示
require后接賓語(yǔ)從句時(shí)，賓語(yǔ)從句必須用should do的虛擬語(yǔ)氣，其中should可以省略。
另外，表示“需要”，且是物作主語(yǔ)時(shí)，后接動(dòng)詞 ?ing形式的主動(dòng)形式表示被動(dòng)含義，可以等于不定式被動(dòng)形式；在這一點(diǎn)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(chē)都需要定期檢修。
They required him to keep it a secret.
他們要求他對(duì)這事保密。

②All the people present agreed that the matter required . （2010?01?山西太原檢測(cè)）
A. to look into B. being looked into
C. to be looked D. looking into
解析: ①選B。be required to do sth.意為“被要求做某事”。第二個(gè)空的to是介詞意為“隨著，伴著”。
②選D。require, want, need表示“需要”，當(dāng)其主語(yǔ)是動(dòng)作的承受者時(shí)，其后的賓語(yǔ)常用動(dòng)詞不定式的被動(dòng)形式或動(dòng)名詞的主動(dòng)形式。

Where B. which C. there D. from where
解析:選D。該句是非限制性定語(yǔ)從句，盡管先行詞可以表示地點(diǎn)，但句中強(qiáng)調(diào)目光的發(fā)出地，所以應(yīng)用介詞from+關(guān)系副詞where。
