—________ do you watch TV?

— Once a week, only on Sunday evenings.

A. How long B. How much C. How often D. How many days

C 【解析】句意：——你多久看一次电视？——一周一次，仅仅载星期六晚上。How long多长（通常指做某事用了多长时间）；How much多少（修饰不可数名词）；How many days多少天； 对频率的提问，要用how often，意为“多久一次”。故选C

These animals are in danger. We should think to protect them.

A. what can we do B. what we can do

C. how can we do D. how we can do

B 【解析】解析：句意：这些动物正处于危险之中，我们应该想想我们能做些什么来保护它们。本题考查宾语从句的用法。think后接宾语从句，宾语从句的语序要用陈述句的语序，what作为do的宾语，而how则不能作为do的宾语。故正确答案为B。

In nature, you may see many insects and animals of different colors. Have you ever wondered why Locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.

Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar(类似的) to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil(土壤） insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.

Have you ever noticed some even stranger acts? The ink fish (墨鱼) in the sea can send out some very black ink when it faces danger. As the ink spreads over (散开) , its enemies(敌人) will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

You can’t look good if you are not healthy. And one way to be healthy is to do exercise.

Football, tennis, volleyball and swimming are all good for you. Muscle (肌肉) exercise is also important. You can exercise at school or at home. Boys can do push-ups (俯卧撑) and girls can do sit-ups (仰卧起坐).

But there are some don’ts here:

First, stay away from weight lifting (举重). It’s bad for you, because it gives too much stress (压力) to your body and you can’t grow tall if you practise often.

You should exercise for about an hour a day, and three days a week. On the other days, don’t exercise too much. Exercising too much is not a good idea.

Don’t go running for a long time. Running for a long time makes you tired.

Don’t want fast results (结果). Your muscles will grow when you get older. If you want to be healthy and strong, exercise and healthy food are the best way. But don’t think you can make it in one day.
