This trend, 16 was started by the medical community with a method of fighting heart disease, has had some unintended side 17 such as overweig
8、ht and heart disease the very thing the medical community was trying to fight. Fat and salt are very important parts of a diet. They are required 18 (process) the food that we eat, to recover 19 injury and for several other bodily functions. When fat and salt 20 (remove) from food, the food tastes a
9、s if it is missing something. As a result, people will eat more food to try to make up for that something missing. Even 21 (bad), the amount of fast food that people eat 22 (go) up. Fast food is full of fat and salt; by eating more fast food people will get more salt and fat than they need in their
10、diet. 23 (have) enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve 24 taste of your food. However, be careful not to go to extremes. Like anything, it is possible to have too much of both, which is not good for the 25 (healthy). Their cheery song brig
11、htens many a winters day. But robins are in danger of wearing themselves out by singing too much. Robins(知更鸟) are singing all nightas well as during the day, British-based researchers say. David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting
12、 the birds biological clock, leading to them being wide awake when they should be asleep. Dr. Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds health at risk. His study shows that when robins are exposed to light at night in the
13、 lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night. He told people at a conference, “There have been a couple of studies suggesting they are increasing their song output at night and during the day they are s
14、till singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy.” And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, “In Glasgow whe
15、re I live, gulls are a serious problem. I have people coming to me saying “You are the bird expert. Can you help us kill these gulls? During the breeding(繁殖) season, between April and June, they are very active at night and very noisy and people cant sleep.” Although Dr Dominoni has only studied lig
16、ht pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.26.
