四、用方框中所给单词和词组的正确形式填空,补全短文
as effect return such as temperature therefore
In the natural world, climate change has had a bad
effect
on some areas. For example, the Arctic (北极) has a quick increase in
temperature
, causing ice to melt. This situation affects the polar (极地) ice trap, where ice reflects (反射) sunlight back into space.
As
ice melts, less sunlight is reflected, causing the earth to have more heat.
Therefore
, the melting of ice can lead to another round of warming. Animals like polar bears, whose homes are in these icy areas, have more difficulty in finding food, leading to a drop in their populations (数量). Among these animals,
such as
seals and walruses (海豹和海象), the loss of ice means they have fewer places to rest. As ice keeps melting, these animals may finally have no choice but to
return
to more northern places to find cooler temperatures and safer ground.

这是一道英语填空题,主要考查学生对词汇、短语及其正确形式的运用,同时需要理解短文内容,根据上下文选择合适的词填入空白处。题目给出了几个单词和词组:as,effect,return,such as,temperature,therefore,要求用它们的正确形式填空。
(1)处需要一个名词作has had的宾语,构成has had a bad effect on(对……有坏影响)的结构。
(2)处需要一个名词作in的宾语,根据后文的ice to melt可知,这里是指“温度”的升高。
(3)处需要一个连词引导时间状语从句,表示“当……时”。
(4)处需要一个副词表示结果,连接前后两个句子。
(5)处需要一个短语来举例说明前文的animals。
(6)处需要一个动词短语表示动物们不得不“返回”到更北的地方。
【答案】:
(1)本题考查固定短语“have a bad effect on sth.”的用法,其中“effect”为名词,表示“影响”,故填“effect”。
(2)本题根据后文“ice to melt”冰融化,可知此处描述的应是“温度”的升高,故填“temperature”。
(3)本题需要一个连词引导时间状语从句,表示“当……时”,且位于句首首字母大写,故填“As”。
(4)本题需要一个副词表示结果,连接前后两个句子,表示“因此”,故填“Therefore”。
(5)本题需要一个短语来举例说明前文的animals,表示“例如”,故填“such as”。
(6)本题根据前文“As ice keeps melting”随着冰继续融化,可知动物们不得不“返回”到更北的地方,且have no choice but to do sth.表示“不得不做某事”,故填“return”。
There are many wetlands in China and some of them have become important nature reserves. The Yancheng Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home
to
many kinds of birds and animals. What's more, the world's
largest
nature reserve for milu deer is also there. These are great places for more than 7,000 milu deer
to live
freely. The temperature in the wetlands is usually not too high
or
too low. There is a lot of rain and sunshine too. The wetlands are good places for wildlife.
Providing
food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands.
Wetlands are important because they also prevent floods from
happening
. But some people want to change the wetlands to make
more
space for farms and buildings.
Luckily, more and more people are beginning to realize the
importance
of wetlands and wildlife. World Wetlands Day is celebrated on 2 February each year. On that day, we can join in many activities to tell people more about wetlands around the world.
