Biodiversity(生物多樣性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each other in some way, biodiversity is desirable. Any loss to the planet is actually a loss for mankind as well, and it is our responsibility to try and save Earth’s biodiversity.
Biodiversity has a vital role to play in the evolution（演變）of species. Species become extinct, but new species evolve, and this is how a balance is maintained. This may sound pretty simple, but it takes millions of years for changes to take place.
Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.
Biodiversity also has an important role to play in human society. Apart from being the most intelligent species on earth, human beings are also the most dependent. We depend on nature to meet our basic needs. When we change the balance of nature to create our cities and bring about our technical advances, we knowing or unknowing cause great damage to the ecosystem. This must be understood, and the damages must be reversed（顛倒）in any way they can to ensure that the balance of the ecosystem is maintained.
小題1:We learn from the first paragraph that_________.
A biodiversity can be seen
B all living species are found on earth.
C people everywhere are aware of the importance of biodiversity
D the loss of any species can affect humans
小題2:Why can change in food webs lead to disaster?
A Because it can make people suffer from disease
B Because it can put huge pressure on some species
C Because it takes a long time for such changes to take place
D Because it will damage ninety-nine percent of species
小題3:What does the underlined word probably mean?
A 畫線  B Peace  C Strength  D Variety
小題4:We learn from the last paragraph that __________.
A humans are as independent as they are intelligent
B the balance of the ecosystem is easily maintained
C nature has given us a lot
D nature is taking revenge on us
小題5:Which of the following may be the best title for this passage?
A Food Webs are Closely Related to Biodiversity.
B Biodiversity Plays a Very Important Role in Evolution

Anger is a kind of feeling. Many things can make you angry. When your teacher gives you too much homework, when your team loses an important game, when a friend borrows your favorite thing and then breaks it, you can get really angry. Usually, your body tells you when you are angry. For example, you breathe(呼吸) faster, your face turns red, and you may want to break something or hit(打) someone, but sometimes, you hide(隱藏) your anger. For example, you may hide it in your heart.

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles.
In the Second World War, some people didn’t use gas made from petroleum(石油) in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we need our trees for other things, too.
Besides different types of gas, we can also use electricity(電) to run our cars, but first we must make the electricity! Some countries have coal(煤) and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines(渦輪機) and make electricity more easily and cheaply.
We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.
Which of these ways will be used to run our cars in the future?
小題1:When might people have to go back to using horses and carriages?
A．When they are poor.
B．When they run out of oil.
C．When they need more exercise.
D．When there aren’t any big trees in the world.
