I saw one topic on the wordreference forum discussing whether a sentence could begin with "Different from" (see the post). The example sentences in that post are
A: Different from Drug A, Drug B can also be administered orally.
B: Unlike Drug A, Drug B can also be administered orally.
It is said that in a textbook (see the pdf, however, it's written in Japanese), sentence A is considered to be a "not so good" expression.
So, is this assertion true? In addition, I think although sentence A is not so good, it is grammatically right, because the verb of the sentence is be---am I right?
To state the question more precisely, I am concerned with the correctness of this form:
- Adj phrase, Subject + Be + ...
For a simple example,
Similar to me, he is tall.
I don't know why but, I think the sentence above sounds OK (at least more OK than a sentence starting with "Different from") ... Is there any explanation in the formal grammar?
Still, I am a little confused about the difference between my example and the detached predicative supplement. In Angela Downing's book English Grammar: A University Course, Second Edition, on page 482, it says:
Detached predicatives ... are a type of supplementive unit, that is, a unit used non-restrictively ... Syntactically, they are not integrated into the unit which they modify. They are thus free as regards position, though in practice they are usually found in initial rather than final or medial positions. They provide an economical means of adding contextual information which fills out the reader's perception of the person or thing referred to. They are common in certain written genres and generally absent from conversation.
The corresponding example sentence in this grammar book is
Angry and tearful, Susan walked out.
It seems this sentence is short for "Being angry and tearful, Susan walked out." So, though it sounds a little like a pedant, the sentence
(Being) Different from Drug A, Drug B can also be administered orally.
might be grammatically right ...
