    There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community（医学界）a method of fighting heart disease, has had some unintended side(effect) such as overweight 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(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt(remove) from food, the food tastes as if is missing something. As  result, people will eat more food to try to make up for that something missing. Even  (bad),  the amount of fast food that people eat goes up. Fast food   (be) full of fat and salt; by  (eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be  (care) not to go to extremes. Like anything, it is possible to have too much of both,  is not good for the health.

    In 1863 the first underground passenger railway in the world opened in London. It ran for just under seven kilometers and allowed people to avoid terrible  (crowd) on the roads above as they travelled to and  work. It took three years to complete and was built using an interesting method. This included digging up the road, (lay) the track and then building a strong roof over top. When all those had been done, the road surface was replaced.

    Steam engines (use) to pull the carriages and it must have been(fair) unpleasant for the passsengers, with all the smoke and noise. However, the railway quickly proved to be a great success and within six months, more than 25,000 people were usingevery day.

    Later, engineers (manage) to construct railways in a system of deep tunnels (隧道）, which became known as the Tube. This development was only possible with the (introduce) of electric-powered engines and lifts. The central London Railway was one of the most (success) of these new lines, and was opened in 1900. It had white-painted tunnels and bright red carriages, and proved extremely popular with the public.

    Last October , while tending her garden in Mora , Sweden , Lena Pahlsson pulled out a handful of small (carrot) and was about to throw them away. But something made her look closer , and she noticed a (shine) object. Yes, there beneath the leafy top of one tiny carrot was her long-lost wedding ring.

    Pahlsson screamedloudly that her daughter came running from the house. “she thought I had hurt(I),”says Pahlsson

    Sixteen years(early), Pahlsson had removed the diamond ring  (cook) a meal. When she wanted to put the ring back on later, it was gone. She suspected that one of her three daughters —then ten, eight, and six— had picked it up, but the girls said they hadn't. Pahlsson and her husband  (search) the kitchen, checking every corner, but turned up nothing. “I gave up hope of finding my ring again," she says. She never replaced it.   

    Pahlsson and her husband now think the ring probably got  (sweep) into a pile of kitchen rubbish and was spread over the garden, it remained until the carrot's leafy top accidentally sprouted (生长) through it. For Pahlsson, its return was  wonder.

    She has turned down several (invitation) to star at shows in order to concentrate on her studies. After school she plans to take a year off to model full time before going to university to get a degree  engineering or architecture.

    Sarah says, "My dad thinks I should take the offer now. But at the moment, school (come) first. I don't want to get too absorbed in modeling. It is(certain) fun but the lifestyle is a little unreal. I don't want to have nothing else to fall back on when I can't model my more."

    While running regularly can make you live forever, the review says it  (be)more effective at lengthening life walking ,cycling or swimming. Two of the authors of the review also made a study published in 2014 showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all (cause).

    According to the World Bank, China accounts for about 30 percent of total(globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005-when the government  (start) a soil-testing program  gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons.

The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid (look) directly into his eyes so he doesn't feel(challenge).

    While regularly eating out seems to(become) common for many young people in recent years, it's not without a cost. The obvious one is money; eating out once or twice a week may be(afford) but doing this most days adds up. There could be an even(high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in (weigh) problems.

    If you are not going to suffer this problem, then I suggest that the next time you go to your mum's home dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

He will swim about 5 to 12 hours each day, depending on the weather. A boat will go him and offer emergency support and space for small breaks.
