1 . Going for a picnic is a good experience to be in nature, but it’s terrible to have a picnic that will do harm to the environment. Here are some ways to keep your picnic green.

Use reusable plates and cups. You don’t need to wash disposable (—次性的) plates and cups because they pollute the environment. It’s greener and cheaper to bring metal plates and cups from home. After the picnic, you can take them home and wash them.

Try to buy food from local farmers’ markets. In general, if you bring less food for your picnic, you’ll create less pollution.

Try to have an all-vegetarian picnic. Modern production of meat uses lots of energy and creates lots of pollution.

Instead of driving, ride a bike or walk to the park. If the park you want to visit is too far from your home, you can take public transportation like buses or subways.

After your picnic, remember to pick up all your trash. Try to keep the picnic area clean. If possible, try not to create any trash at all and reuse whatever you can.

3 . Every April 22 people come together to take action that will protect the environment. One theme of Earth Day is “Invest (投资) In Our Planet”. So how is investment in eco-innovation helping to deliver a more sustainable future?

When it comes to the environment, it can be argued that the technology industry is both the problem and the solution. Tech is responsible for between 3.5% and 4% of global greenhouse gas emissions (排放物). And the EU believes the Information and Communication Technology (ICT) sector is responsible for10% of all electricity consumption. On the other hand, we all want a sustainable future for the planet. Yet we also want the convenience and fun of modern living. Obviously, only eco-innovation can deliver the solutions.

Eco-innovation is the key to doing more with less. All over the world, and across many different industries, innovators are working to reduce the human footprint while improving productivity. Innovative farming is a good example.

Until recently, most agricultural improvements focused on the development of machines. Now digital tools are causing a new wave of efficiency. Innovative farming companies look to increase farm efficiency and reduce input waste through farming techniques. And they are using real-time devices located in the field or in equipment. The data collected by these devices help farmers make better decisions about where to provide effort and resources while reducing the environmental footprint.

As people’s awareness of environmental protection continues to increase, the tech industry needs to keep working on the inventions like those described above. These breakthroughs will help us all to do more with less. Also, tech companies are facing calls to keep their own houses in order. Lawmakers and consumers want them to use fewer materials in the production process and rethink their approach to recycling and waste. The good news is that governments and eco-innovative companies have already carried out a major clean-up mission.

5 . I live in a town, about half a mile from the banks of a river, It had been raining buckets that week and there were _________ warnings for nearby areas, but not where I was.

As a precaution (预防), I’d _________ sandbags outside my garden door just in case water managed to flow through. As I fell asleep, I was _________ by the sound of rushing water.When I swung my legs off the bed, I was _________ to feel cold water already up to my kneesand rising fast. Trembling, I _______ my phone on the table and _________ the flashlight. Water was coming from the garden door. The river must have _________ burst its banks and broke the sandbags. And now I had to get out--fast!

With the water up to my waist, in bare feet I started to paddle (蹚水) to my only _________ the door leading to outdoors. Finally, I made it to that door and _________ to pull it open, but the water’s __________ was high. Anyhow, with great efforts, I made a __________ of about 30 centimeters, enough for me to get through. Rushing down outside, I __________ that if I hadn’t woken up in time, I would have drowned. Many houses around us were __________ , including a home for the disabled.

I learned to be grateful through the experience and determined to live each day to its __________ .I will remember a famous saying: “Don’t remember the day when you lost everything. Remember the day you__________ .”

7 . Life today is much easier than it was hundreds of years ago, but has brought new peoplems. One of the biggest is pollution. Pollution come in many ways. We see it, smell it, drink it and even hear it.

Men have been polluting the earth. Many years ago, the pollution was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, men moved to another place.

Air pollution is now the most serious. Air makes people sick. And lots of people now are trying to use something to clear the air. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.

Many countries are making rules to fight air pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air.

Pollution by SO² is now the most dangerous kind of air pollution. It is caused by heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.

Although most of the pollution is caused by us, we are the ones who can change the situation. The earth is our home. We must take care of it. And we must pay more attention to the information in pollution at the same time.

Tibetan antelopes live on the plains of Tibet, Xinjiang and Qinghai. When I     1     (watch) them move slowly across the green grass, I am struck by their     2     (beautiful). At the same time, I am also reminded     3     the danger they are in. Right now they     4     (hunt), illegally, for their valuable fur.

Zhaxi who works at the Nature Reserve (保护区) says, “    5     (actual), we are trying to save ourselves, not only the animals.” In the 1980-1990, the number of the antelopes     6     (reduce) by 50 percent. The hunters were shooting antelopes     7     (make) profits. Their habitats were becoming     8     (small) than before,     9     new roads and railways were built.

In order to save them, the government take     10     (effect) measures and the antelope population has recovered. In June, 2015, the Tibetan antelopes was removed from the endangered list.

9 . Topher White spends so much time walking in the forest and thinking about how quickly we’re losing it. The engineer is determined to stop global deforestation. Founder of the San Francisco-based non-profit Rainforest Connection, White has developed a small but clever strategy: using old cell phones to listen for the sound of destruction.

Forests are disappearing worldwide, and fast：an area about half the size of England is lost each year. The Amazon has lost close to one-fifth of its rainforest cover in the last four decades. Forest loss not only harms wildlife, including many species that live nowhere else, but it’s also a big contributor to the greenhouse gas emission(排放)that cause climate change.

”I didn’t know any of this when I started,“ says White, who began his journey in 2011, when he traveled to Indonesian Borneo to help decreasing gibbons(长臂猿).

Between 50 and 90 percent of the logging that happens in the world’s rainforests is illegal, according to White, yet detecting chainsaws(电锯)and other sounds related to that activity can be tough, because the air is already filled with the loud unpleasant mixture of sounds from nature. So he has developed a system in which he installs a cell phone that stays charged by solar cells, attaches an extra microphone, and listens. From there, the device can detect the sounds of chainsaws nearly a mile away.

Because it’s unfeasible to have people listening to the devices all the time, he added some “old-school data analysis”, so that the cell phone’s computers can distinguish a chainsaw’s sound from others in the forest. This way, his device can automatically detect logging activity and send a text alert to authorities who can determine if it’s illegal and then stop it.

White notes that he’s not alone in the fight: Many people and organizations are working tirelessly to stop forests from disappearing. For instance, local groups are particularly active in forest conservation efforts, White says.

So far, his monitoring devices have been used in Cameroon, Ecuador, Peru, and Brazil and will soon be used in Bolivia. It’s not just about listening for logging. The same technology that can pick out the buzz of a chainsaw can pick out the sounds of specific birds, which is why Whtie sees the forest recordings as a potential science tool. He’s urging biologists and ecologists to use his monitoring system anywhere, whether it’s a remote forest or a park in London. “The more we learn about these places,” he says, “the easier it’ll be to protect them.”
