b The solution… comes at a time when it is in
serious trouble.
e It is in serious trouble. The solution... comes at this
time.
c Sadly, human activity is the main reason why the
number of monarch butterflies is falling.
f Sadly, human activity is the main reason. For this
reason, the number of monarch butterflies is falling.
What's the difference between the two groups of sentences
a Eventually, it manages to reach the places where
it will spend the winter.
d Eventually, it manages to reach those places.
It will spend the winter there.
Sentences (a), (b) and (c) contain a clause defining a noun or pronoun in the sentence. Sentences (d), (e) and (f) are constructed with a pair of simple sentences, with one defining a noun or pronoun in the other sentence in each pair.
Why does the author choose to use sentence (a), (b) and (c) in the reading passage
Because there is a closer link and connection between the item and the clause defining it in sentences (a), (b) and (c). It will also make the passage clearer, and create an emphatic effect on the location, time and reason being defined.
In April 2017, two giant pandas from China arrived at a zoo in the Netherlands. There, they were welcomed to the Chinese-style compound where they were to live. On 30 May, after the preparations were complete, the day finally came when the pandas met their fans for the first time. People were excited - the zoo is the only place in the country where it is possible to
see pandas. In fact, the last time
there were pandas in the
Netherlands was in 1987. And of
course, the main reason why they
were so excited is that pandas are
just so cute!
Practice
Read the passage and underline the words that where, when and why refer to.
