Chinese achievements in pollution control, ecological recovery and protection, and green development China     1     (make) in the past decade were highlighted at a Friday press briefing,     2     a senior official pointed out China’s     3     (participate) and leadership in global climate governance.

According to the press briefing, China has been the fastest in improving air quality and the PM2. 5 level in cities at the prefecture level and above dropped by 34. 8 percent from that of 2015. Days with good air quality reached 87. 5 percent. Pollution of water bodies and the soil is also     4     (effective) tackled. Ecological systems     5     (protect) and restored. National parks are set and more than 300 endangered animal and plant species saw their wild populations recover, marking achievements in protecting ecological diversity.

The country has taken     6     active part in cooperation on climate change. It has done its     7     (good) to help other developing countries to improve their climate response capacity     8     (reduce) the harmful impacts of climate change. It also has distributed over 1. 2 billion yuan on climate change and trained about 2, 000 officials and experts in the field of climate change     9     more than 120 developing countries.

    10     (head) forward, China will work with all parties to actively participate in the global governance of climate change.

The milu deer certainly seemed happy to be back in China because their numbers started     1     (grow) steadily. There were soon so many of     2     (they) that 64 milu deer     3     (send) to a newly opened reserve in Shishou, Hubei Province from Beijing in the 1990s. They can move     4     (free) in the reserve and feed entirely on wild plants.

At the moment, the milu deer are still living in reserves     5     they are being protected     6     cared for. As a result, their population     7     (be) now recovering fast. Soon a new chapter will be added to the strange tale of these special     8     (animal). The deer are being trained to survive outside the park so that they can one day all return     9     the wild. The resue of the milu deer is already a     10     (succeed) story. Now it is up to us to make sure that the deer live happily ever after.

3 . In today’s world, where the consequences of climate change are becoming increasingly evident, the need for energy conservation has never been more pressing.     1    .

Use your laptop more than your desktop

Laptops use an average of 20 to 50 watts of electricity to run, whereas desktop computers use an average of 60 to 200 watts of electricity to run. The reason for this is that laptops run off of battery power and desktops are continuously plugged into a power source that drains energy.

    2    . Not only does this help reduce your energy usage, but it also optimizes your laptop’s battery life to last longer.

Charge your phone in airplane mode and before bedtime

While charging, switch your phone to airplane mode, so that the phone does not slow down the charging process by continually burning energy trying to connect with cell phone towers and plot your location with its GPS function. When you switch to airplane mode your phone charges more quickly.

The brighter the screen setting, the more power it uses and vibration uses more energy than a ringtone.     3    , therefore less energy consumption. And remember-unplug your charger if not in use!

Unplug mobile phone and laptop chargers

Always unplug electronics and appliances when not in use.     4    . When the power strip is left on, the devices plugged into it continue to use energy and actually increase your energy usage. The Northern Resources Defense Council found that devices in sleep or standby mode account for about one- quarter of all residential energy consumption.

    5    

Reduce your carbon footprint by organizing your files and eliminating unnecessary data from cloud storage! Companies offering cloud data storage need warehouses filled with servers running nonstop. These data centers consume massive amounts of energy since they require AC systems to avoid overheating.

4 . Photographer Joe Sartore began making studio portraits (肖像) of________in 2006. The purpose is to________for future generations species that someday might be extinct. Sartore expects to have portraits of nearly 1,000 animals. Here are some________of his project, which is featured in this special issue on________wildlife.

In Sartore’s opinion, the Rabbs’ fringe-limbed tree frog (巴拿马树蛙) is one of the most________species he has photographed that have since gone________. A few years ago there was one left________, a male, at the Atlanta Botanical Garden. He had________it there times before it passed away. At those moments he thought to himself________, “Don’t mess this up.” It might be this animal’s only________to have its story told well.

Another memorable species Sartore photographed is the Florida grasshopper sparrow (草蜢沙鹀). It is endangered, but seems to be________back. It’s a small brown bird, and some people________it enough to try to save it. There are many________stories, such as the California condor, the Mexican gray wolf, sand so on. They all got down to perhaps two dozen or fewer individuals, but they’re all________now due to human efforts.

The situation is still________as a recent report says that as many as one million species are already on their ________to extinction. It’s foolish to think that we can throw away so much________and not have it affect humanity in a(n)________way. Sartore’s goal is to get the________to care about the extinction crisis while there’s still________to save the planet.

The number of Amur tigers, also known as Siberian tigers, moving from Russia into northeastern China,     1    (increase) because of lower levels human activity, improvements in their habitat     2     a smoother transit corridor between countries. The area     3     tigers lived across the Sino-Russian border expanded by about 12 kilometers every three years from 2003-2016. In 2021 the Northeast China Tiger and Leopard National Park was established.     4     (cover) approximately 14,100 square kilometers, the park straddles the provinces of Heilongjiang and Jilin. By the end of 2021 the number of wild Amur tigers living there     5     (rise) to 50 from 27 in 2017. The conservation of tigers is recognized as a global challenge, due to     6     (they) expansive habitat requirements. A female needs 400 to 500 square kilometers while a male requires over 1, 000 square kilometers. The collaboration between these neighboring parks creates a     7     (share) home for the animals. The construction of the Sino-Russian cross-border environmental corridor is vital     8     several barriers hinder the movement of tigers between the two sides. Border fences and roads built in the area are among those obstacles. Efforts are required by both sides     9     (promote) the corridor. As the population of prey species including wild boar and deer rises, Amur tigers are travelling     10     (far) into China for food. The expansion of the tigers’ range is expected to continue.

8 . Climate change is causing more areas to turn into deserts. This issue is affecting the lives of 250 million people as land that used to be good for farming becomes dry and unproductive. Around one-third of the world’s land is impacted, including regions in Africa, southern Europe, Asia and America.

Sand to Green is a Moroccan company that can transform a patch of desert into a sustainable (可持续的) and profitable plantation in five years, according to Wissal Ben Moussa, its co-founder and chief agricultural officer. The solution is using agroforestry (农林业)to create a new kind of agriculture that is sustainable and that can be resilient (有适应力的) in front of climate change.

The system can be set up close to any source of salty water, which Sand to Green cleans using energy from the sun. It then grows different types of fruit trees and plants together in the same area—a method called mixed planting—and waters the plants’ roots directly with the cleaned water, to reduce water loss to the air. The soil is regenerated using what Sand to Green calls “green manure”, a mixture that includes compost, biochar(生物炭)and microorganisms that help the soil “wake up”. Biochar is a form of charcoal that can help dry soil hold on to water.

In a five-hectare trial in southern Morocco that’s been running since 2017, Sand to Green has tried out a variety of plants in search of the best performers. Among the intercropping herbs (草本植物) that have been successfully trialed are rosemary, geranium, vetiver and citronella, which Ben Moussa describes as “very low-maintenance and very high-profit”.

Sand to Green is now working to scale up to a 20-hectare commercial site, also in southern Morocco. It says a site of that size would cost around $475,000 to set up and would start bringing financial returns in about five years.

According to Ben Moussa, with this system they create biodiversity, which means better soil, healthier crops and a bigger yield. The plantation can generate 1.5 times more yield, thus making more money than a farm that grows only one type of crop in the same space.

9 . It’s now, more than ever, crucial to adopting a low-impact lifestyle since all kinds of waste, including that of the fashion industry, are piling up in landfills with astonishing speed.     1     Thankfully, the following tips can help you reduce clothing waste.

·Buy fewer clothes overall.     2     It’s a more cautious approach to shopping and consumption (消费) in general. Think twice about what you will buy and say no to over consumption. You can even try out a minimalist (极简主义的) lifestyle. Shop for what you need only when necessary, keep things simple, and go back to basics.

·Shop for high-quality clothing. High-quality clothes can cost more at first but save you money in the long run.     3     Moreover, quality clothes can make you feel more comfortable and confident, improve your fashion style, and help you look your best.

·    4     Upcycling is very beneficial to the planet and your budget (预算). Instead of throwing old clothes away, use parts of or entire old clothes to make something new and more valuable. You can even create stylish and unique pieces of clothing by upcycling.

·Donate your unwanted fashion items. Do a quick online search for your local options to donate clothes that are still in good condition. Be sure to contact organizations first and ask them what type of clothes they accept. You can donate clothing to for-profit companies or to homeless shelters and family service agencies.     5
