Wind is one of our cleanest and most abundant power sources. Europe is leading the way in wind power. Nearly 75% of all turbines(风力发电机)     1    (locate) there. The country that produces the most energy from wind is Germany. However, Germany     2    (consume) a lot of energy, and wind only supplies about 5% of all its electrical needs. Denmark is the global leader in this field, which uses wind     3       (supply) almost 20% of its energy.

This is the year 2070. Today is my    1     (fifty) birthday, but I look like a person of eighty- five. I have serious kidney (肾脏) problems because I don’t have enough water     2     (drink). I’m afraid I don’t have much time left to live. I’m already one of the oldest people in this society.

I remember when I     3     (be) five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half     4     hour. At that time,     5    (woman) all had beautiful hair. Now, we have to shave (剃光) our heads to keep them clean without the use of water.

I remember there were “Saving Water” warnings in many public places, but nobody     6     (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much     7     (expensive) than gold and diamonds.

In the past, doctors suggested adults drink eight glasses of water a day. Nowadays, I am allowed half a glass only. Most people are weak and sick.

When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers     8     how healthy people were. When he asks, “Why is there no clean water now?” I feel guilty (有罪的). I belong     9     those people who simply turned a blind eye to all the warnings.

I hope the people living in the 2020s     10     (true) understand the importance of saving water.

4 . Landscaping (人造景观) refers to man-made features of a landscape such as driveways, walls, steps, and other human-made structures. It has many sustainability benefits.

Replace Lawns (草坪)

Fertilizers and pesticides (化肥和杀虫剂) help establish a beautiful lawn.     1     If you replace lawns with landscape, you’ll use fewer chemicals and do less harm to the environment.

Use Less Water

    2     So it can save hundreds of gallons of water and reduce the carbon emissions (排放) used to provide that water cleanly.

Use Locally-Produced Materials

Materials for landscaping are almost all produced locally, due to the high shipping cost.     3    

Lower Garden Maintenance (维护)

Usually, Americans spend two hours per day on lawn and garden care.     4     That often means less energy used to run some garden equipment.

Reduce Ice Build-up

Sustainable landscape allows stormwater to drain (流) into the soil.     5     This means safer walkways or driveways, and a reduced need for salt for de-icing (除去……上的冰).

5 . My love for animals began through watching wildlife documentaries when I was a kid. I went on to ________ Environmental Science at university, and became ________ in marine biology when I did my PhD. at the University of Hong Kong. That’s when I ________ that there was a possibility to do more for Hong Kong.

I was very lucky to ________ Ms. Claire Nouvian when I graduated from my PhD. in 2009. At that time, Claire was ________ another non-profit organization, BLOOM Hong Kong, after founding the Bloom Association in France a few years before, and she hired me to work on ________ marine conservation. We do this mainly by being research focused, arousing public ________, and trying to fill knowledge ________. We then share our information with frontline officer, such as fishery managers and customs officers, to help them ________ how important their role is in implementing (贯彻执行) regulations to the wildlife trade, and ________ suggestions on how to make implementation work more ________.

We are sill a city in love with ________ and Hong Kong has the second highest annual seafood ________ in Asia — but consumers are ________ aware of where their seafood comes from and which species are ________.

With the marine ecosystem already ________, the greatest threat is continued ignorance and inaction. We humans have been a ________ part of the problem, but now it is time for us to show that we can also be a part of the ________. If each person around us ________ their part — even for just one meal a day Hong Kong would already be on its way to making considerable ________ towards sustainable seafood consumption.

Over and over at the UN climate summit in Glasgow, world leaders have stressed the need     1     (limit) global warming to 1. 5 degrees Celsius. Experts have said crossing the 1. 5 ℃threshold(界限）risks     2     （release) far more severe climate change effects on people, wildlife and ecosystems. Preventing it     3     (require) almost halving global CO₂ emissions(排放) by 2030 from 2010 levels and cutting them to net-zero by 2050.

Already, the world has heated to around 1. 1℃ above pre-industrial levels. Each of the last four decades was     4     (hot) than any decade since 1850. “We never had such a global warming in only a few decades,” said climate     5     (science) Daniela Jacob at the Climate Service Center Germany.

More warming to 1. 5 ℃ and beyond will     6     (worse) such impacts. For example, heatwaves would become both more frequent and more severe. A warmer atmosphere can also hold more moisture(水分), resulting in more extreme rainfall     7     raises flood risks. It also increases evaporation, leading to more intense droughts.

“At 1. 5 ℃, there’s     8     good chance that we can keep most of the Greenland and west Antarctic ice sheet     9     collapsing,” said climate expert Michael Mann at Pennsylvania State University. That would help limit sea level rise to a few     10     (foot) by the end of the century.

9 . The ocean covers more than 70 percent of the earth’s surface and the deep sea could contain as many as 100 million species. But it’s becoming worse. Overfishing, plastic pollution, rising sea levels, and climate change are to partly blame (责怪) for the ocean’s present state.     1     But there are still some things we can do to improve the situation.

People are talking about plastics more than ever after recognizing the heavy effect the material has on our planet. Every year, thousands of seabirds, sea turtles, seals, whales, dolphins, and fish are killed after mistakenly eating plastics.

    2     You can buy reusable water bottles instead of plastic ones. When buying things, take a reusable shopping bag and choose the product that isn’t covered with plastic packaging.

Keeping our coastlines clean is a simple way to help the planet. After a day at the beach, make sure you’ve taken everything with you, including rubbish.

    3     Common sun cream chemicals can harm ocean life. Search for sun cream made with eco-friendly ingredients (成分).

    4     Consider making a donation (捐赠) to an organization working to help the ocean. The American Cetacean Society helps protect the habitats of whales, dolphins, and other marine (海洋的) animals through educational programs.

Being mindful of what cleaning products you use is another effective way to reduce your effect on the earth. Chemicals like household cleaners can move through waterways and eventually end up in the sea, affecting the health of oceans and the animals in them.     5     You can often use simple ingredients like baking soda, vinegar (醋), or lemon juice to complete many household chores.
