（2017﹒江苏南京）Many countries all over the world have National Parks. There are about 7, 000 National Parks around the world. Most of them protect natural settings as well as the plants and animals that live there, but a few are in towns and cities.

Are there National Parks in England?

There are nine National Parks in England. The first three were the Peak District, the Lake District and Dartmoor, which were all named as National Parks in 1951. Others followed afterwards, such as the North York Moors in 1952, the New Forest in 2005 and the South Downs in 2010.

Are National Parks in England the same as those in other countries?

Many National Parks around the world cover huge areas of land where nobody lives, but in England most of the countryside within them is useful for farming and other activities. As a result, National Parks in England include places where people live and work, as well as wild and beautiful areas where there is little sign or human life.

Why do visitors go to the National Parks?

There are plenty of activities to do in all of the National Parks in England. Visitors can walk or cycle, following marked route, and many of the parks organize activities for families.

Are there any problems in the National Parks?

There are about 110 million visitors to the parks every year, bringing many benefits to the areas but creating problems too. Many popular towns and villages can be swamped(充斥) by visitors. This results in overcrowded car parks and roads choked (堵塞) with traffic. Life can be difficult for people who live there, as more and more gift shops and cafes are opened instead of those everyday shops; in popular areas, house prices can become too high for local people making it hard for them to stay in the area.

Another major problem is litter. In the parks it is a particular(特别的) danger to animals. Broken glass can also cause fires by focusing the rays of the sun. When these start in wild places, they are much harder to control and can damage (毁坏) large areas very quickly.

How can people help?

All National Parks in England promote(倡导) the Countryside Code, which tells people how to take care of their environment. If these rules are followed, the National Parks will be protected and continue to give pleasure to many people for a long time.

Today there are more fires than in the past . Over 100,000 wildfires burn each year in America . Russia has 20,000 to 35,000 wildfires and Australia has about 60,000 each year. These fires destroy（损害）huge areas of forests and burn hundreds of homes .

Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate（气候）change . In 2010, Russia had the hottest and driest summer with strong winds in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives .

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire as quickly as they could. They didn’t allow the grass and trees to burn. As a result , today many forests have thicker vegetation（植被）which provides more fuel（燃料）for fires . So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow some fires to burn naturally. The fire makes old trees thinner. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore , if a fire is not a serious threat（威胁）to people , firefighters may let it burn naturally .

1.Russia had so many fires in one month in 2010 because __________ .

A. lightening spread the fire

B. there was much fuel for fires

C. there were not enough firefighters

九年级英语阅读理解中等难度题查看答案及解析

Today there are more fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy huge areas of forests and burn hundreds of homes.

Many experts believe _______. The first is climate change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes, dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn't allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被). Thicker vegetation means more fuel for fires. also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat to people, firefighters may let it burn naturally.

There are about 80,000,000 mines*  under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50  people including many children were’ killed ‘or htirt each iay.  In 2003,  APOPO,  a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng rats to search for the mines.

The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp*  sense of smell.  The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.

In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana.  The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu.  “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”

After nine months’  training, the rats were taken to a minefiel山  They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers*  that they smelt out’a mine.  Then the mine was cleared. It had  taken two ‘deminers  a day to clear a 200㎡ . minefield,  but with the help of two rats ‘they could finish it in two hours.

The rats and ~he deminers saved thousands of lives,  “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.

1. The APOPO trained the rats to search for ________.

A. children    B. animals      C. mines     D. bananas

2. While training the rats, the trainers have to be

A. patient     B. clever        C. brave         D. serious

3. How long did the training last?

A. Two hours.    B. One day.    C. Four weeks.    D. Nine months.

4.Which of the following is NOT TRUE according to the passage?

A. Each day about 200 people were killed or hurt by mines,

B.The APOPO started to train the rats in January 2004.

C. The trainers gave the rats food after they smelt out a mine.
