题型:单项选择题

If you enjoyed the spring-like sunshine over the weekend and thought the weather has finally turned a corner, you’re sadly mistaken.

Chilly (寒冷的) days and grey clouds are forecast for the week—making it far too early to pack away the winter woollies.

Temperatures will struggle to rise above zero at night and fail to make double figures during the day.

People enjoy the spring sunshine in Sefton Park, Aigburth, Liverpool. Forecasters have predicted a return to chilly weather this week.

Met Office forecaster Charlie said, “It was a nice, dry, bright weekend in many parts and Monday is going to be a similar affair for many.”

“Temperatures will be between 5℃and 8℃, which is below average for the start of spring.”

The sun will disappear from the south of the country after today, with dry but cloudy conditions forecast for tomorrow and Wednesday. 

Wednesday will be warmest of the three, with temperatures peaking at 9℃. But this is still two degrees below the March average for the district.

Overnight, temperatures will drop sharply, with lows of minus 3℃for the next three nights.

“It will generally stay on the cold side of average,” said Mr. Powell.

The March misery comes at the end of the coldest winter for more than 30 years.

Temperatures in December, January and February struggled to stay above zero, with the UK’s average 1.5℃, making it the deepest freeze since 1978—79.

It claimed there was just a one-in-seven chance of a cold December to February.

The agency also sadly predicted a “barbecue summer”, saying it was “quite optimistic” that it would be warmer and drier than average.

Following the two mistakes, the Met Office has dropped its long-range seasonal forecasts and will instead publish a monthly prediction for Britain, updated once a week.

In its defense, it says that while short-term forecasts are extremely accurate, Britain’s size and geographical position makes long-term predictions much more challenging.

It also points out that it gave warning of any heavy falls of snow this winter.

A. The big chill isn’t over yet                     B. A warm spring finally arrives

C. A heavy snow is on the way                 D. The Met Office drops forecasts
