Prepare for Water Day Zero
Last year，Cape Town said it was facing Water Day Zero．That was the date when the city's taps would go dry．It was first expected to arrive in April，2018． Thanks to hard efforts and a rainy season，it has been put off（推迟）．（1） ．And it may hit cities all over the world．
How did Cape Town get into a Water Day Zero situation？The city gets its water from six reservoirs（水库）．They usually fill up during the rainy season，from May through August．However，since 2015，the city had been suffering from its worst drought（旱灾）in a century．（2） ．Even worse，Cape Town's population grew greatly．As a result，the need for water rose．
（3） Because of climate change，serious droughts are becoming more and more common．At the same time，people are moving to cities．The United Nations says by 2050，two thirds of the world's population will live in cities．Since 2014，southeastern Brazil has been suffering from its worst water shortage in 80 years．In Mexico City，many of the 21 million people only have running water for half of the day．
Luckily，steps can be taken to avoid water crises（危机）．To start with，all of us can do something to save water and slow down climate change．（4） At the same time，water pollution must be stopped．
The world now has a chance to stop a series of Water Day Zero crises． If we don't act，many cities may soon face a time when there isn't a drop to drink．
| A．Cape Town is not alone． B．The serious situation seems to be improved． C．Water levels in the reservoirs became very low． D．Cities can build more water﹣recycling factories． E．However，the problem is very likely to appear again． F．More and more countries are paying attention to the problem． |
The natural world teaches us a great deal about recycling (循环再利用). In nature, recycling happens every day. For example, when leaves fall to the ground, they will turn into compost (肥料), helping ____ grow healthily and strong. When an animal dies, it becomes food for ____ animals. Nothing is wasted. But humans have created things like plastic bags ____ can’t be broken down by nature. Our rubbish kills animals and ____ water and soil. ____ we continue making too much rubbish, the problem will only get ____ . If nature can’t reuse the rubbish, we ____ recycle it. We should clean up the rubbish we’ve made because nature can’t.
Recycling is important. In reusing material instead of throwing it away, we can also benefit from it. ____ the Earth is rich in natural materials like water and trees, these materials are not endless. We use up our natural materials much faster than the Earth is able to reproduce them. For example, each year we ____ more than 6,000 square miles of forest. But it ____ an average of 25 years for a new tree to grow.
Recycling can help us save the Earth, so let’s take action right now.

Is it possible to have a diet（日常饮食）that's both healthy and friendly to our planet？Here are answers to your eco﹣friendly food questions.
Does what I eat influence climate（气候）change？
Yes.The world's food system is responsible for（为……负责）about one quarter of the planet﹣warming greenhouse gases that humans produce each year.That includes raising and harvesting all the plants，animals，and animal products we eat，as well as processing，packaging，and shipping food to markets all over the world.
Which foods have the largest influence？
In general，beef and lamb have the biggest climate footprint per gram of protein while plant﹣based foods like beans，rice，corn and wheat have the smallest influence.Pork，chicken，eggs are somewhere in the middle.
Is there a simple food choice I can make？
Studies have shown that people who eat a meat﹣heavy diet can reduce their food-related footprint by one third or more by moving to a vegan diet ﹣ no meat，dairy（乳制品），or eggs.If you don't want to go that far，just eat less meat.
Can I really make a difference to our planet？
We need more food to feed the world's growing population.One person alone can make only a tiny difference.If many people make changes to their diets，that will start to add up.It will make a greater difference if the world's heaviest meat eaters make some changes to their diets.

In China，a lot of food is wasted every year and the waste food is enough for people. The food is wasted in restaurants, at home and in schools, etc．

Look at the Earth from.space.Why does our planet look so blue？Its blue because water covers almost three quarters of the Earth's surface.Water is not just an important part of our planet.It is an important part of our body，too.More than half of our total body weight is water.
Our body loses water whenever we exercise or.go to the toilet.That's why we need to drink plenty of water every day.We drink water.We use it to cook，clean，and carry waste out of our homes.Farmers use it to grow vegetables and crops like rice and corn；factories use it to make products.
Since the 1950s，the amount（数量）of water people use has increased by three times.But the water supply（供应）hasn't.Scientists worry that soon there won't be enough water for us，as well as for the animals and plants that share our world.What can we do to help？Use water wisely.
Having enough water isn't our only problem. We also need it clean.
Right now，ships and factories are putting wastes into seas，rivers and so on.Even chemicals that farmers use are running into rivers and lakes.All this pollution can make the water dangerous to drink.It can also harm fish and other water﹣living lives.
We must do something to stop pollution.It's the best way to protect our world's most valuable natural resource（资源）.

A fish that lives in America can live out. of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up, they live. on the land, said Scott Taylor, a researcher in Florida.
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
"We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.
"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land," Wright said.The Mangrove Rivulus is a type of fish that_________.
| A．lives on land in Africa |
| B．can stay alive for months out of water |
| C．prefers living in dry places |
| D．is the longest living fish on earth |

| A．breathe through its skin | B．be found in Asia |
| C．keep alive out of water | D．keep alive and walk on land |
Which one of the sentences below is not true?
| A．The Mangrove Rivulus fish can live out of water as long as other animals if it has something to eat. |
| B．Millions of years ago, animals began to live onto land from water. |
| C．Lungfish found in Australia, Africa and South America can live out of water in a not active way. |
| D．The walking catfish found in Southeast Asia can stay on land for hours at a time. |
