初中英语选择题,请大家选择完答案告诉我为什么选这个,谢谢大家啦!<答案已知,求详解>

1. Those guests___at the front row came here from a European country early this morning.
A who seated B seating C were sitting D seated

2.It is said that agrave of a middle-aged man ___about 2300BC was found by some English archaeologists in the year of 2002.

C dating back to D dated from

3.The citizens didn't feel safe at all afer several families had their houses____at night and a lot of things stolen.
A.broken in B broken into
答案是D C A

这三题都是考动词的非谓语形式v-ing和v-ed.
这三题答案应该是:D C B.
分析如下
1,seat 当动词,“使就座”解释一般有二种 用法。
a,接反身代词,如:
He seated hemself in a chair.
b,人物作主语时,用被动态。如:
All the guests were seated in the living-room.
上述选项中,A,必须是 who were seated.
C,B,主动态是不对的。答案这有是D。
2,正确的形式有:
a,dating from b,dating back to
c,dated back
对比只有先 C。
3,“break in” 一般作“打断,插入”,
“break into”作 “非法闯入民宅”之 意,故选 B。

1.选D,过去分词作状语,seat是“使.....就坐”的意思,当然这题如果有“sitting”也可以选
2.C,和上题差不多,分词的用法
3.A,break in表示闯入(状态), break into 表示强行闯入 (动态)
这题中,.....已经闯入了!

是不是1、D 2、C 3、B?我觉得是这样,1的解释 seated 是过去分词,在句中作状语,2的解释短语:date back to...“追溯到……”。主要强调back to (时间往回推) date from “开始于……强调from (从何时起)
表示追溯时通用
date back跟一段时间,表示向前追溯多久
3的解释break in
1.强行进入,闯入;打断,插嘴
2.破门(窗)而入;打断,插嘴
3.训练;强行进入;打断

break into
1.非法闯入,强行进入
2.闯入;打断;突然开始…;突然…起来
3.破门而入,闯入

第一题选D,seat作动词常用被动,这是一个过去分词作定语。
第二题选C,上题讲被动用过去,这题是现在分词作定语。
第三题选B,have sth done使某事被做。
