Ⅰ　阅读理解
A

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that you can eat it. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat food with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

2．Certain animals change their choice of food when ________.
A．the season changes
B．the food color changes
C．they move to different places
D．they are attracted by different smells

3．Which of the following eats only one type of food?
A．The white butterfly. B．The small bird.
C．The bear. D．The fox.
答案：A　细节理解题。根据文章第二段第四句可知，一种白蝴蝶只吃白菜叶子，故A正确。
4．We can learn from the last paragraph that ________.
A．food is chosen for a good reason
B．French and British food is good
C．some people have few choices of food
D．some people care little about healthy diet
答案：D　推理判断题。根据文章最后一段第二句可知，通常，人类吃某种食物不是因为这些食物有营养，而是爱吃，故推断出人们选择食物时并不十分在意健康问题，故答案选D。

Are African wild dogs really dogs? What's the difference between African wild dogs and the dogs we know as pets? For one thing, African wild dogs, which live in Africa, only have four toes, while domestic (驯养的) dogs and wolves have five. But you won't want to count for yourself, because they are truly wild animals.
“Wild dogs are not somebody's domestic dogs that ran away and didn't come back, although some people used to think that，” explains Dr McNutt, who studies these animals at Wild Dog Research Camp in the African country of Botswana. “They are actually Africa's wolves, and just like wolves, they do not make good pets. They need to be out in the wild doing what they are supposed to do—find the food they need to survive and feed their babies.” In fact, they travel so far that researchers have to use radio collars (颈圈) to keep track of them. The collars send out radio signals that tell people where the dogs are. No two wild dogs have the same pattern of coats, so it is easy to tell them apart.
African wild dogs are smart and sociable, like pet dogs. Adult dogs, male and female, are willing to take good care of young ones.
Millions of domestic dogs live on the planet, but there are probably fewer than 6,000 African wild dogs left. Humans hunt them and farmers who don't want them to go after cows and sheep poison them. Humans are also destroying the wild, natural habitat (栖息地) they need to survive in. Fortunately, today more farmers are finding other ways to protect their cows and sheep from African wild dogs instead of killing the animals.
篇章导读：本文是一篇说明文。主要介绍了非洲野狗的生活习性及现状。
5．Which of the following can explain why African wild dogs are different from domestic dogs?
A．African dogs can live longer than domestic dogs.
B．African dogs have fewer toes than domestic dogs.
C．African dogs are much bigger in size than domestic dogs.
D．African dogs are much more dangerous than domestic dogs.
答案：B　细节理解题。根据第一段第三句可知，非洲野狗只有四个脚趾，而家养的狗和狼有五个脚趾，由此可知B项正确。
6．In Dr McNutt's view, African wild dogs ________.
A．are a kind of wolves
B．can be trained as pet dogs
C．actually are missing domestic dogs
D．generally are not used to living in groups
答案：A　细节理解题。根据第二段第一、二句可知，Dr McNutt认为，非洲野狗不是那些跑了却没有回来的家养狗，尽管有些人过去常常这么想。他们实际上是非洲的狼群……，由此可知在Dr McNutt看来，非洲野狗就是一种非洲狼，故选A项。
7．What suggestion does the author give in the last paragraph?
A．Farmers should use domestic dogs to fight against wild dogs.
B．African wild dogs should be protected instead of being killed.
C．Farmers should take responsibility for feeding African wild dogs.
D．African wild dogs should be used to protect farmers' cows and sheep.
答案：B　推理判断题。根据最后一段内容可知，幸运的是，今天更多的农民正在寻找其他方法来保护他们的牛羊免受非洲野狗的伤害，而不是杀死这些动物。由此可推知，我们人类应保护这些数量并不多的非洲野狗，故选B项。
8．Which of the following can be used as the title of the passage?
A．How to keep wild dogs
B．How to train domestic dogs
C．An introduction to African wild dogs
D．Differences between domestic dogs and wild dogs
答案：C　标题判断题。通读全文可知，本文主要对非洲野狗的现状作了介绍。分析选项A.How to keep wild dogs “如何饲养野狗”；B.How to train domestic dogs “如何驯养家养犬”；C.An introduction to African wild dogs “介绍非洲野狗”；D.Differences between domestic dogs and wild dogs “家养犬与野狗的区别”可知，最好的题目应当是C(介绍非洲野狗)，故选C项。
Ⅱ　应用文写作
