2. 种类：主要有形容词、名词、代词、数词、介词短语、动词不定式（短语）、分词、定语从句等相当于形容词的词、短语或句子作定语。

Grammar: attributive clauses
1 Look at the sentences from the reading passage and answer the questions.
a Eventually, it manages to reach the places where it will spend the winter.
b The solution... comes at a time when it is in serious trouble.
c Sadly, human activity is the main reason why the number of monarch butterflies is falling.
1 What do “where”, “when”and“why” refer to in each sentence
“where” refers to “the places” in sentence (a), “when” refers to “a time” in sentence (b) and “why” refers to “the main reason”in sentence (c).
Compare them with the following sentences and answer the questions.
d Eventually, it manages to reach the places. It will spend the winter there.
e It is in serious trouble. The solution... comes at this time.
f Sadly, human activity is the main reason. For this reason, the number of monarch butterflies is falling.
2 What’s difference between the two groups of sentences
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 other sentences in each pair.
d Eventually, it manages to reach the places. It will spend the winter there.
e It is in serious trouble. The solution... comes at this time.
f Sadly, human activity is the main reason. For this reason, the number of monarch butterflies is falling.
3 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.
Compare them with the following sentences and answer the questions.
Now look for more sentences with these structures in the reading passage.
...there may come a time when the number of monarch butterflies increases once again.
These two pieces of information -- the time of day and the point where the sun is in the sky...
In many of the places where the butterfly can be found, people are destroying the natural environment.

Back to nature
Hi Kay,
We’re having an amazing time here in South Africa. Our accommodation is perfect. It is in a location 1 we can watch animals wandering past on their way to waterhole. Sunset is the time of day 1 we sit on the balcony and count how many giraffes or antelopes we can see. I guess this is the
reason 1 this place is so popular. Next week,
we are going to fly up to Zambia. That’s one of the
countries 1 you can visit the famous Victoria
Falls.
See you soon.

5 Complete the paragraph with the animal idioms.
English idioms are a way of adding colour to the language. For example, instead of saying “It's raining heavily”, you could say “1_______________ ________”. Another reason to use idioms is that they are concise. For example, to describe someone who is always working or busy doing something, we can say they are 2______________. If they're rushing into something and should wait and be patient, you could say “3____________ ______”. Learning idioms can be fun, especially when we compare them
to Chinese equivalents. Take, for example, “4________________________
____________” (people do what they want and have fun when someone in authority is absent) and “5_________________________” (solve two problems with one action) - are there corresponding idioms in Chinese
It's raining cats
as busy as a bee kill two birds with one stone hold your horses
When the cat's away, the mice will play. It's raining cats and dogs.

□ Learning to learn
In a debate, first listen out for the main topic. This is usually a statement or question at the very start of the debate. Speakers will state whether they are for or against the statement. Then, they will introduce their supporting arguments with expressions such as
We must remember that… and We can’t deny that…
