    When you take a walk in any of the cities in the West, you can see a lot of people (walk) with dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog (change). In the old days people used to train dogs to protect themselves against attacks by other beasts. And (late) they came (realize) that a dog was not only useful for protection, willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without (permit). But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. But the (important) reason is for companionship. For a child,  dog is his best friend when he has no friends to play with. For young couples, a dog is child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection  friendship.

    Eating organic food will not make you healthier, according to researchers at Stanford University, although it could cut your {#blank#}1{#/blank#}(expose) to pesticides(杀虫剂). They looked at more than 200 studies of the content and {#blank#}2{#/blank#}(associate) health gains of organic(有机的) and non-organic foods. Overall, there {#blank#}3{#/blank#}(be) no difference in the nutritional content, although organic food was 30% less likely {#blank#}4{#/blank#}(contain) pesticides.

    The researchers looked at 17 studies comparing people who ate organic {#blank#}5{#/blank#} those who did not and 223 studies {#blank#}6{#/blank#} compared the levels of nutrients, bacteria, and pesticides in various foods. However, none of the human studies ran for longer than two years, {#blank#}7{#/blank#}(make) conclusions about long-term{#blank#}8{#/blank#}(outcome) impossible. And all of the available evidence was{#blank#}9{#/blank#}(relative) weak and highly variable, which the researchers said was unsurprising because of all the different variables.

    Dr Crystal Smith-Spangler, the lead researcher, said “Some believe that organic food is always healthier and more nutritious. But as {#blank#}10{#/blank#} matter of fact there isn't much difference between organic and conventional foods, if you're an adult and make decisions based simply on your health.”
