这个是时态问题,括号里得用现在分词形式,而这句话的时间先后顺序是先没有收到他的来信,然后才着急,所以应该用现在分词的完成时态,即,having done.另外给你附上分词的用法:
概述:
分词在句中起形容词和副词的作用,可作
表语,定语,状语和宾语补足语.
分词有两种形式:现在分词(doing)和 过去分词(done).
一、分词的时态和语态
A.过去分词只有一种形式,它表示一个被动或完成的动作.例如:
The fallen leaves means the autumn’s
coming.(表完成)
The building built last year is our library.(表被动)
B.现在分词可分为一般式和完成式两种;在语 态上可分为主动语态(一般式:doing/完成式:having done)和被动语态(一般式:being done/完成式:having been done).
(1).一般式:在时间上表示一个正在进行,或与谓语动词同时发生或存在的动作和状态
例如:The boy swimming in the river is
his brother.
(2).完成式:在实践上表示该动作限于谓语动词的动作或状态
例如:
1.Having finished the job,she went home.
2.Having been criticized by the teacher,
he decided to study hard.
二、分词的否定式:not+分词
例如:
1.Not having received his letter,he decided to call him.
2.Not knowing his address,she cannot get in touch with him.
三、分词的作用
1.作宾语补足语 分词作宾语补足语,要看分词与宾语的关系.若为
主动关系,则用现在分词;若为被动关系,则用过
去分词.
例如:
(1)When I went into the classroom,I saw all the classmates (writing )composition according to what the teacher said.
(2)He had his leg (injured )in the basketball match yesterday.
2、作定语(相当于一个定语从句) 分词作定语要看分词与它所修饰的名词之间的关系.
若为主动关系,则用现在分词;若为被动关系,则用过去分词.
例如:
(1)、The meeting (held) last week is of great importance.
对比:The meeting which was held last week is of great importance.
(2)、The boy (playing )football on the playground is my brother.
对比:The boy who is playing football on the playground is my brother.
3、作状语 分词作状语要看分词与其逻辑主语(即主句的主语)
的关系.若为主动关系,则用现在分词;若为被动关系,则用过去分词.
例如:
(1)、Seeing from the mountain,we can see our beautiful school.
(2)、Seen from the mountain,our school looks more beautiful.
4、作表语 现在分词作表语表示主语所具有的性质和特征;过去分词作表语表示主语所处的状态.
例如:
(1).Watching the exciting football match,they were very (execited).
(2).The football match is very (exciting).
另外,现在分词通常用来修饰物;过去分词通常用来修饰人或与人的感情色彩、面部表情相关的词.如:an interesting story; a surprised look等.(此种情况只有以下词汇可以使用:bore,exhaust(筋疲力尽),amaze,confuse,shock,surprise,interest,
excite,disappoint,astonish,worry,please,satisfy,frighten,terrify等)
累死了,一个一个的敲啊~

不可以,having表示有时间先后
也就是说先是没收到他的信我才担心的
如果句子有明显的时间先后的话必须加having的
