1、當(dāng)2個句子滿足以下2個條件：1、2個句子主語一致,即此題都是he；2、從句里是由be動詞做謂語.那么,那個從句就可以省略主語及be動詞,直接保留be動詞后的成分即可,可以是形容詞,分詞短語等.省紀委省略,he is buried in thought.若選B,則為he is being buried in thought
2、選reported,
本意：
A,formally announce (sth); make known clearly 正式宣布（某事）; 表明
B make (sth) known publicly 宣布; 宣告; 發(fā)表,強調(diào)公開,比如:They announced their engagem ent to the family.他們向家里宣布他們已經(jīng)訂婚了
C,permanent account,esp in writing,of facts,events,etc （對事實﹑ 事件等的）記錄;
（尤指）記載,如a record of school road accidents 學(xué)生出席﹑ 交通事故記錄
D,give a spoken or written account of (sth heard,seen,done,studied,etc);
describe （以口頭或書面形式）報告或報道（所聞﹑ 所見﹑ 所做﹑ 研究所得等）;
正對此意
當(dāng)年我也錯過,
