England is not a big country: from north to south and from east to west it is only about three hundred miles across.But for a small country it has a surprising range of climate. People who have never visitedEngland or who have visited only one part of it often makes the mistake of thinking that it is a cold and wet country.Except for the summer months of June to September, this is probably true of the north ofEngland and the Midlands. In the south, however, the climate is much more pleasant. One result is that when people retire from the job in the north, they often prefer to move down to the south.

Perhaps the warmest part of the country is the southwest, which consists of (is made up of) the counties ofDevon andCornwall, where palm trees, bamboo and many semitropical plants grow well. Flowers and vegetables ripen as much as a month earlier than those elsewhere. Farmers in the areas gain a higher price for their vegetables and flowers because they are ready earlier. In winter there may be several feet of snow in other parts ofEngland but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one ofEngland’s most popular holiday areas.
In the north ofEngland and the Midland, ______.
A、it is cold and wet all the year round
B、the climate is pleasant as a whole
C、it is warm most of the time in a year
D、only the summer is not cold and wet
