这道题问什么选D 希望您帮满讲解下 谢谢

答案

Some people in the past at night dug the _____treasures in the tombs.
第一题 意思是
在过去,一些人在晚上去挖掘埋藏在坟墓的宝藏. 首先宝藏是被放进坟墓的 所以是被动 其次 B的意思是埋 而A的意思为藏起来 D的意思为被盖起来 所以选择B是最合适的
He worked hard,______,he didn't pass the exam
碰到类似的题目,只要是前后都有逗号的空,一般都是选择D.however.
表示转折：尤其用于谈及一个既成事实时,表示转折,其意为“可是”“仍然”等.可放在句首、句中或句末,通常用逗号与句子其他成分隔开.如：My father, however, did not agree. 但是,我父亲不同意.My room is small; however, it’s comfortable. 我的房间很小,但却很舒服.My room is small; however, it’s comfortable. He said that it was so; he was mistaken, however.

他说情况如此,可是他错了.注：however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)注意正句中的标点符号.如：我们都已尽了最大的努力,不过我们还是输了.误：We all tried our best, however we lost the game. 正：We all tried our best, but we lost the game. 正：We all tried our best; however, we lost the game. 正：We all tried our best. However, we lost the game. (3) 表示惊奇或强调：相当于how ever的用法,其意为“究竟怎样,到底以什么方式”.如：However did you get here without a car? 没有汽车你究竟是怎样来的呢? 没有汽车你究竟是怎样来的呢However does he manage to write music when he is so deaf? 他聋成这个样子,究竟是怎样从事作曲的呢?
