Biodiversity(生物多样性), 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(演变)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(颠倒)in any way they can to ensure that the balance of the ecosystem is maintained.
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
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
3.What does the underlined word probably mean?
A Immovability B Peace C Strength D Variety
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
5.Which of the following may be the best title for this passage?
A Food Webs are Closely Related to Biodiversity.

When we say someone is in a blue mood, it means he or she is unhappy or sad. It’s important for everyone to be happy. Here are some fast and easy ways to cheer you up.
Exercise
When you exercise, your brain gives out a chemical called Endorphin (内啡肽). This chemical makes you feel happy. That is why exercise is good for you.
Have a talk
If something or somebody is troubling you, don’t quarrel with other people to relax yourself. It is a good idea to have a heart-to-heart talk with a friend or a family member. Tell them your feelings. A chat is a useful way to make you feel better.
Have some hobbies
For example, playing pop music, drawing something or listening to your favorite music will make you smile. Act like an artist. Draw, paint or make something. Being active and creative makes you feel more satisfied and less nervous.
Laugh more
Laughing is the best way to improve your moods. Children laugh about 400 times a day. Adults only laugh about 20 times a day. What happens? Experts say if we laugh more, we will be happier and healthier.
Think positively
Close your eyes and imagine a beautiful scene or a time. Never think about anything terrible that you can’t change. What’s more, leave your flat and go outside. Sun and fresh air are good for you. Be a kid for a day. Play games, watch comedy movies or read jokes online.

The first picture is of Abraham Lincoln (1809-1865). He became the 16th president of the United States in 1861, just 14 years after he was first elected to the House of Representatives.
On Friday, April 14, 1865, he and his wife planned to go to see a play at Ford's Theater. His secretary, named Kennedy, advised him not to go, but he went anyway and was shot in the head as he watched the play. He died the next day, and Vice-president Andrew Johnson (1808-1875) became President.
The man who shot Lincoln, John Wilkes Booth, shot him in a theatre. He escaped to a warehouse, but was shot, or killed himself, before being captured.
The second picture on the right is of John F. Kennedy (1917-1963). He became the 35th president of the United States in 1961, just 14 years after he was elected to the House of Representatives.

His secretary, named Lincoln, advised him not to go, but he went anyway, and was shot in the head on Friday, November 22, 1963, as he drove through Dallas in a Ford Lincoln Continental.

Dragons can be friendly or fierce (凶猛的).They can bring good luck or cause death, but one thing is sure—people talk about them almost everywhere in the world.
In Chinese culture, dragons are generous and wise, although they can be unpredictable.The dragon was closely connected to the royal family:the emperor's robes (礼服) have a symbol of a gold dragon with five claws.Other members of the royal family were allowed to wear dragon symbols, too, but with fewer claws and of a different colour.According to popular belief, if you are born in the year of the dragon, you are intelligent, brave, and a natural leader.
But in the west, dragons have a different reputation (名声).The very first text in English, the AngloSaxon poem Beowulf, tells the story of a Scandinavian hero, Beowulf, who fights and kills a dangerous dragon but he himself is killed in the fight.However, across the border in Wales, the red dragon which appears on the Welsh flag is a positive (积极的) symbol, indicating strength and a sense of national identity.
①Why_should_the_dragon_have_a_different_character_in_different_parts_of_the_world? Some experts believe it is because of the animals that the myths(神话) grew out of.In the west, the idea of the dragon probably came from the snake—an animal which people hated and were afraid of(害怕).
But in China, the idea of the dragon may have come from the alligator—a shy animal which lives in rivers, but which is usually only seen when there is plenty of water—a good sign for agriculture(农业).②因此中国龙是好运的使者(bringer)。
1.Are there any differences between Chinese dragons and western dragons?
_______________________________________________________________________________________
2.In China, if a boy is born in the year of the dragon, what do the people think of him?
