UK Could Miss Carbon Emissions Targets in 2020s
Committee on climate change tells government current emissions cuts are too small to meet longer-term targets.
[A] The UK is on track to miss its carbon targets in the 2020s, the government’s advisers on climate change warned on Wednesday. Efforts to cut emissions are not happening quickly enough, and a looming "policy gap" will lead to a shortfall in the investment and infrastructure needed for a low-carbon economy, they said.
[B] Last year, UK greenhouse gas emissions rose by 3.5%, in a setback to the government’s plans for strict "carbon budgets" that stipulate (规定) steep falls in emissions from now to 2027. The rise was owing to the cold winter and more power coming from coal, which is currently cheap.

Step Back in Time
Do you know that we live a lot longer now than the people who were born before us One hundred years ago the average woman lived to be 45. But now, she can live until at least 80.
One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for U.S. and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily.
But in order that we don’t slip back into bad habits, let’s have a look at what life was like 100 years ago.
Families had between 15 and 20 children, although many babies didn’t live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor

[填空题]Sport is one of the world’s largest industries, and most athletes are professionals who are paid for their efforts. Because an athlete succeeds by achievement only-not by economic background or family connections-sports can be a fast route to wealth, and many athletes play only for money than for love.
This has not always been tree. In the ancient Olympics the winner got only a wreath of olive leaves. Even though the winners became national heroes, the games remained amateur for centuries. Athletes won fame, but no money. As time passed, however, the contests became increasingly less amateur and cities began to hire athletes to represent them. By the fourth century A.D., the Olympics were mined, and they were soon ended.
In 1896, the Olympic games were revived with the same goal of pure amateur competition. The roles bar athletes who have ever received a $50 prize or an athletic scholar or who have spent four weeks in a training camp. At least one competitor in the 1896 g
