Look at the sentences from the reading passage (P5) and answer the questions.
0,000 people reading my blog! b I love to photograph the rising sun, …
Disappointed by his behaviour, I said all this to my best friend.
Approached in this way, your friendship will soon be repaired.
Q1. Who was disappointed in sentence (a)
What is approached in sentence (b)
Disappointed by his behaviour, I said all this to my best friend.
Approached in this way, your friendship will soon be
repaired.
Q2. Why does the author use -ed instead of -ing here
Because -ing is used when the action is done by the subject of the sentence, while -ed is used when the action is done to the subject of the sentence. Here, both “disappoint” and “approach” are actions done to the subjects.
0,000 people reading my blog! b I love to photograph the rising sun, …
a. Disappointed by his behaviour, I said all this to my best friend.
b. Approached in this way, your friendship will soon be repaired.
c. Because I was disappointed by his behaviour, I said all this to
my best friend.
d. If it is approached in this way, your friendship will soon be
repaired.
Q3. What is the difference between the two groups of
sentences
Group(a, b)______________________.
Group(c, d)_______________________.
contains -ed as adverbial
contains adverbial clauses
0,000 people reading my blog! b I love to photograph the rising sun, …
a. Disappointed by his behaviour, I said all this to my best friend.
b. Approached in this way, your friendship will soon be repaired.
c. Because I was disappointed by his behaviour, I said all this to
my best friend.
d. If it is approached in this way, your friendship will soon be
repaired.
Q4. Why does the author choose to use -ed instead of an
adverbial clause in the reading passage
Because -ed makes the sentences shorter and sound more formal as written language.
Homework
Go over “The Past Participle as the Adverbial”.
