Living places
The home of the elephant is in the deep forest． It is the largest of all land animals， and is found both in Asia and Africa． One of the main places in Asia where the elephant lives is the island of Ceylon． The huge forests on the island become the home of thousands of elephants． The trees grow thick and tall． They make many parts almost dark， while bright sunlight is above and around them．
Living habits
The elephant likes the deep part and the coolest places of the forest． There he will stand swinging his ears， to drive away the flies； or he will pull down a branch （树枝） from a tree to fan himself． He likes bathing， and to be near a lake or running water． There he takes in the water with his trunk， and spreads it all over his body．
Food
The elephant enjoys the fruits in the forest， and also the leaves of the trees． There is plenty of food for him in the forests， though he is not always happy with what he finds there．
Way of movement
When a group of elephants moves about in the forest， the oldest goes first． The young elephants and their mothers are in the middle， where they are safest． Then all move along with a great noise， the branches of the trees bending and breaking before them． Though the elephant is usually harmless， no one dares to attack （袭击） a group of them moving through the forest．
How people treat them
In Asia the elephant is trained to work． At one time the African elephant also was trained． Soldiers in ancient times often went to fight on the backs of African elephants． But now the elephant that lives in Africa is illegally （非法地） hunted mainly for its valuable ivory． In order to protect them， governments around the world have developed laws to stop this．

In Australia there is a famous island called Fraser Island．A great many visitors come here for holidays every year．Why？The reason is that it is special．（56） ．In fact，it is the largest sand island in the world．It's about 200 kilometers long and 240 kilometers wide．
Though the island is a popular place of interest，there is no airport on the island．The long beach along the east coast works as the airport．（57） ．
On the island there are sand hills without any plants，but there are forests with old trees，beautiful flowers and over a hundred lakes，too．（58） ．
Every year，visitors come to enjoy the island's natural beauty．People like camping and hiking there．（59） ．Animals were killed for food and this made them in danger of extinction （灭绝）．They threw rubbish everywhere，and the lakes were seriously polluted．
（60） ．Rules have been set up．For example，visitors are not allowed to use motorboats （摩托艇） or go fishing in the lakes，and they mustn't leave any rubbish．
A．Planes arrive and leave from here
B．Anyone who breaks the rules w il be pun i shed
C．The island is completely made of sand
D．Unluckily，visitors have caused many problems
E．Many kinds of birds and animals live in the forest
F．So it is time to protect the environment of the island．
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．

Death Valley is a huge place．It is more than 225kilometers across the southern part of the state of California，and across the border （边界）with the state of Nevada．
（1） It can be dangerously cold during the winter months．The air temperature during the summer can be as high as 57℃．The heat of Death Valley has killed people in the past．It will continue to kill those who do not honor the climate．Death Valley does not forgive （原谅）those who are not careful．
Death Valley was named by a woman in 1849．（2） Thousands of people from other parts of the country traveled to the gold mining （开采）areas in California．They were in a hurry to get there before other people did．
Many people were not careful．They made bad choices or wrong decisions．One group of people had reached Death Valley by December．They avoided the terrible heat of summer，but there was not enough water．There were few plants for their work animals to eat．The people could not find a pass through the tall mountains to the west of the valley．（3） They had to kill their work animals for food and began to walk out of the valley．

A city without cars would be very strange，right？But Venice is such a city．
Venice is in the northeast of Italy．It wasn't built on land，like Beijing or Shanghai，but on more than 110islands．Seawater is everywhere around the city．
Even so，travel isn't difficult．The waterways have always been the best way to get around．There are 117waterways and more than 400bridges that can guide you where you want to go．People in Venice move from place to place by boat．
Water makes the city special，but it is also a big problem．Sometimes tourists will have such strange experiences．One moment they walk across the Rialto Bridge，and there's nothing special．But when they come back to the bridge an hour later，it's underwater and everyone is wearing rain shoes．
Once，people used too much underground water．This made the city get lower little by little．Now the city has gone down by 23centimeters．Another problem is the rising seawater．The temperature has risen over the years．This has made the ice of the Arctic Ocean （北冰洋） melt（ 融化）．Every year，high waters hit the city in autumn and winter．When a lot of water comes，more than half of the city is underwater．
Scientists are trying different ways to stop the city from getting even lower．The Italian government has asked some of Italy's biggest companies to build the MOST project，which was planned to be build under the seawater to stop the rising water．Anyway，this project is helping solve the problem．

Copenhagen is a city full of fairy tales （童话故事）．If you want to explore it，you have to spend a long time and walk slower to enjoy yourself．Copenhagen was the first city to have a street for walkers only．The city has less traffic noise and pollution than any other European capital．
Walking along the river banks，you'll see the Amalienborg Palace first．The king's family is living there．
Churches and castles show us the original（最初的）city．Copenhagen became the capital of Denmark in 1445．But fires in 1728 and 1795 completely destroyed（摧毁）the old wooden buildings．Much of what we see today dates back to （追溯到）the 19th and early 20th centuries．
Keep going，and you'll see the Christiansborg Palace．The town of Copenhagen began there．Then you will see Nyhavn （尼哈芬），a waterway，which was dug in 1673．When you see it，you'll understand why Hans Christian Andersen made this beautiful waterway his home．Nyhave is a peaceful and wonderful place．You'll usually see some rich people walk along here．

Fraser Island is in Queensland，Australia，about 200 kilometers north of Brisbane．It is about 120kilometers long and 240 kilometers wide．It is a very important island because it is completely made of sand．In fact，it is the largest sand island in the world．There is no airport on the island，but there is a long beach along the east coast．Planes arrive and leave from here．
The sand makes unusual shapes．There are hills made of sand called sandblows．Nothing grows on them．They move one or two meters a year from the northwest towards the southeast of the island，getting bigger and bigger．At other places on the island，such as Rainbow Gorge，The Cathedrals and Red Canyon，the sandy rocks have different colors．Sometimes the rocks are so brown that they turn the sea brown，like coffee．
Surprisingly，the sandy island has a lot of different plants and animals．There are dark forests﹣eucalyptus woods，beautiful flowers and over a hundred lakes．There are many kinds of birds，like owls and curlews．There are many animals there，too，such as crocodiles，flying foxes and wild dogs called dingoes．
About 500，000 people visit the island every year to see the island's beauty and nature．People enjoy camping and hiking（徒步）there．Unluckily，the visitors create problems．They damage plants and frighten animals．Their sun cream（防晒霜）makes the water dirty．So it is necessary to manage the visitors．For example，people may not use motor boats or go fishing in the lakes，and they need official papers to drive there．

Living on an island might sound wonderful． But what if you left for a trip and found you could never return？ What if your home， and even the land it stood on， was gone forever？For people living in the Pacific Islands，this is really possible．
Why？ Climate（气候） change． Climate change is causing the sea to rise． That's bad news for the Pacific Islands． Young people on the islands are even starting to wonder：Will they be the last generation（一代人）？
Not if the islanders have anything to do about it．These people are deeply connected to their homelands． The Pacific Islands are made up of 11 different countries： the Marshall Islands， Fiji， Samoa，and others． But now， those countries are working together． They're joining forces to fight climate change．
Why is climate change such a huge threat to this part of the world？Islands have low elevations（海拔）．So they are among the first places influenced by rising sea levels． That's why countries of the Pacific Islands are working together to do their part．
But these are small countries． When it comes to climate change， can they make a big difference？ They can， because most of the things that people on islands buy are brought by ships．This is very harmful to the environment． After all， ships put out almost 3 percent of the world's carbon emissions（碳排放）．That makes climate change worse．
Pacific Islanders realize the problem． So， in 2019，six countries got together：Fiji，the Marshall Islands， Samoa，Vanuatu， the Solomon Islands， and Tuvalu． They came up with a plan． They agreed to cut carbon emissions from shipping by 40 percent by 2030．And by 2050，they expect zero﹣carbon shipping．
How will they pull this off？ They plan to use some really cool carbon﹣free technologies．They'll make use of solar and wind energy．
Sea levels are rising， but hopes aren't sinking in the Pacific Islands．
（1）What is the bad news for the Pacific Islands according to the passage？
A． Some Pacific Island countries have disappeared．
B． The sea level is going up because of climate change．
C． All the sipping to the Pacific Islands has been stopped．
D． The Pacific Islands have nothing to do about the climate change．
（2）The underlined word "threat" in Paragraph 4 probably means" "．
A． risk
B． step
C． project
D． development
（3）It can be inferred from the passage that ．
A． there will never be zero carbon emissions from sipping
B． solar and wind energy will make climate change worse
C． all the Pacific Islanders may leave their homelands by 2050
D． some Pacific Island countries may have hopes to make a difference
（4）The passage mainly talks about ．
A． why other countries are helping the Pacific Islanders fight climate change
B． how some countries are working hard to develop carbon﹣free technologies
C． how Pacific Island countries are working together to fight shipping pollution
D． why Pacific Island countries put out so much of the world's carbon emissions
