Nearly all our food comes from the soil（土地）. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter（糞）from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers（化肥）are also very useful. The same crop（莊稼）should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.

小題3:Which is the best food for soil in the field?

B．Because we don’t have enough land.
C．Because we want to have a different food.
D．Because we do this as a habit（習(xí)慣）.

WIRES is short for Wildlife Information and Rescue Service. It is an Australian  organization, established(成立) in 1985 to care for injured and orphaned(失去母獸的) native wildlife. WIRES has a network of hundreds of volunteers who rescue and care for native animals until they are well enough to be released (釋放)into the wild. Volunteers look after rescued animals in their own homes and are trained in the special needs of native wild animals.
When Australians find a native animal in trouble, they often call WIRES for help. WIRES may be asked to look after a possum that has been attacked by a cat, rescue a large lizard that has got its head caught in a drink can, or care for a baby animal who has lost its mother. People call WIRES when they want to move a dangerous snake away from their garden or when they find a seabird that has swallowed(吞下) a fishing line or an owl with a broken wing. Sometimes kangaroos jumped onto the road in front of cars and are run over. Australians are encouraged to check the pouch(育兒袋)of dead kangaroos in case there is a baby in it. WIRES volunteers find themselves caring for many babies orphaned in this way.
Each year, in the summer, parts of Australia suffer from(受苦) huge bush fires. These fires not only destroy human homes and put people in danger, but they also destroy animal habitats(棲息地)and endanger the animals living in the bush. After a big fire, WIRES and other organizations go into the district to pick up surviving animals. They are treated for burns, shock, smoke and other problems and then cared for until new location can be found for them.
WIRES is also involved in educating people in the importance of caring for wildlife and wildlife habitats. Volunteers visit schools and other public places to talk about native animals. Sometimes they bring a bat or some other interesting animals with them to show to people who may never have seen one up close before.
小題1:What is WIRES?
A．It helps the pets in the street to look for their homes.
B．It rescues and cares for animals in order to set them free.
C．It consists of hundreds of volunteers from all over the world.
D．It provides services for wild animals and keeps them in a zoo.
小題2:Which of the following is TRUE according to the passage?
A．Australians often call the police for help if they find animals in trouble.
B．Volunteers in WIRES are afraid to take snakes away from communities.
C．Australian government asks WIRES workers to save animals after a fire.
D．WIRES often go to the public places to give lessons of wild animals.
小題3:What’s the passage mainly about?
A．It mainly talks about what WIRES members usually do.
B．It tells us why WIRES develops so quickly in Australia.
C．It teaches us how WIRES can train wild animals at home.
D．It mainly tells us how we can join in WIRES successfully.

A ban on smoking in most public places goes into effect(效果) on Sunday in China - home to a third of the world's smokers. That means around 300 million smokers will no longer be allowed to light their cigarettes in the "enclosed public places." These include hotels, restaurants, theaters and public transport waiting rooms. The ban does not cover offices or factories.
The campaign is aimed at controlling(控制) the number of deaths from smoking-related illnesses, running at a million a year. According to the World Health Organization, more than 3,000 people die every day in China because of smoking. Health experts also hope it will help Chinese to raise the knowledge of the dangers of smoking.
But the new rules have been criticized because they do not include punishments(處罰) for those who choose not to obey them.Most people worry that Chinese smoking ban may have little effect.
Business owners often hate rules that force(強(qiáng)迫) them to ban smoking on their restaurants, bar, cafe..., because many customers(顧客) do not like the rules and complain. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar.
It appears that many Chinese people don’t know the dangers of smoking. Research suggests only one in four knows the harm(害處) cigarettes or second-hand smoke can cause.
At the same time the government makes a lot of money from the sales of cigarettes by the state-owned firms that make and sell all tobacco products throughout the country.

A. 禁令                          B. 責(zé)罵                         C. 罰款
