With economy development there comes a time when the old must give way to the new.     1     (keep) the right balance between progress and the protection of cultural sites can be     2     big challenge.

Big challenges, however, can sometimes lead to great solutions. In 1950s，the Egyptian government wanted to build a new dam     3     the Nile. But water from the dam would     4     (possible) damage a number of temples and destroy cultural relics. After     5     (listen) to the scientists and citizens, the government turned to the United Nations for help. After a process of     6     (prepare), finally a document     7     (sign), and the work began in 1960.

Temples and other cultural sites were taken down piece by piece, and then moved and put back in a place     8     they were safe from the water. In all, thousands of engineers and workers rescued 22 temples and     9     (count) cultural relics.

The project ended in 1980, it was considered a success. Not only had the countries found a path to the future, but they had also learned that     10     was possible for countries to work together to build a better tomorrow.

2 . The idea that having narrow local focus leaves little room for anything but a selfish mindset is a misconception, according to a new study that found that concern for local affairs could help with global environmental conservation.

You might have heard of NIMBY which means “not in my back yard” and describes an individual or group opposed to a new addition to the neighborhood, typically a factory, roadway or power station. Nimbyism and parochialism(眼界狭小), which is a focus on a local area,   can go hand in hand, and there are concerns that parochialism paves the way for prejudice, narrowmindedness, and selfishness.

But researchers found the exact opposite to be true in a new study published. The researchers argue that positive parochialism can inspire a larger awareness of global environmental problems and encourage people to action.

“We did not find evidence that parochialism was necessarily negative and inward -looking,” said Patrick, a researcher for the study. “It can be those things, but there's no necessary conflict between feeling connected to your local area and feeling connected to the wider world. ”

For the study, the researchers reviewed documents from the 1987 Parish Maps project. The researchers showed how the Parish Maps project also demonstrated a passion for the environment and conservation. The researchers say that the Parish Maps project is a strong example of “positive parochialism”, and shows that thinking locally can influence a global mindset.

“For a long time,   it has been generally agreed that if we want people to think about global affairs they need an international worldview-but this may not be the case,” said Patrick. “Given where we are now in terms of trying to encourage people to make changes to help the environment, positive parochialism offers something that has been overlooked.”

3 . A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.

Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.

Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the   delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.

Meal kits can reduce transport emissions(排放)if people go to the supermarket less   frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.

However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.

New Yorkers were shocked in early December when a creature as big as a school bus     1     (surface) from the Hudson River. Over the next three days,    2     humpback whale (座头鲸) swam by several popular tourist destinations, where a journalist took    3    (photo) of the animal seemingly waving its tail at Lady Liberty.

Scientists say NYC0089, which hasn't been spotted in several weeks, has likely returned to deeper waters south of the Hudson. Still, the     4    (frequent) of whale sightings in the broader area has gone up rapidly in recent years.

“With these numbers increasing     5     (sharp), it's not surprising that you're seeing them in some unusual places,” says Brown — a biologist. Including the Hudson River and Staten Island.

Scientists say the     6    (rise) whale sightings are likely related to purer water and a brimming buffet of Atlantic menhaden, a fish favored by humpbacks, resulting     7     landmark environmental regulations     8    (pass) in the 1970s as well as New York city cleanup efforts.

“Seeing more whales in this area is a sign    9     the waters are cleaner and there's more food here for these whales,” Brown says. “It shows     10     we've been doing is working, so we need to keep doing that — and more — to protect these species.”

High on the Qinghai-Tibet Plateau     1    (lie) China’s “water tower” Sanjiangyuan. It is home to the headwaters of China’s three rivers: the Yellow River, Yangtze River, and Lancang(Mekong) River. It is the three rivers     2     provide water for about half the population of China. However, human activities are putting this ecosystem     3     risk. Hopefully, though, we can repair this damage. In 2016, the Chinese government established Sanjiangyuan National Park in Qinghai province. The park,     4    (schedule) to open in 2020, has increased the area’s green coverage and attracted more wildlife. The local government has also made great effort to improve biological diversity. The success of Sanjiangyuan will mark the start of a     5    (green) future. With Sanjangyuan     6    (take) the lead, nine other regions in China     7    (choose) by a field conservation station to carry out projects over the past three years,     8     will form a national park system together. The idea of a national park system is still new in China, but    9    (it) realization is urgent. After all, building an ecological civilization bears great       10    (important) in the development and progress of human civilization.

7 . When we think of bicycles, we think of fun and the outdoors. Bicycles give riders the freedom to explore and enjoy the environment and its surroundings.     1    

Most people know that riding bicycles is environmentally friendly.     2     If you are riding a bike, you are helping to reduce air and noise pollution.

Bikes are becoming more and more popular across the world. In fact, they are becoming more than just a fun pastime (娱乐).     3     For many people around the world, access to markets and schools would not be accessible without a bike.

    4     Some cities, such as Paris and Barcelona, have not only built bicycle lanes but also have introduced a system of renting bikes. You can rent, or use a bicycle in one area of the city and drop it off in another area of the city. Paris now has thousands of bikes for public use, with bicycle stations located throughout the city.

Some South American cities, such as Bogota in Colombia, have a weekly car-free day.     5     On these days, the traffic-related air pollution from old buses and trucks is greatly reduced.

It seems that the bike is a force for good, providing solutions for cleaner cities without leaving a serious environmental footprint.

Earlier 2019,the International Center for Integrated Mountain Development published    1    most comprehensive analysis up to now of how climate change will affect the glaciers of the world,    2    (warn) that about 18,00 glaciers(冰川) will disappear by 2100.

This is a bad    3    (predict) for some 1.9 billion South Asians,    4     use water from the glaciers not only for drinking but also for agriculture, hydroelectric power,and tourism. But the survey also looked at an immediate question: As the glaciers     5    (rapid) melt, where will all the water—more than a quadrillion gallons of it, almost the amount    6    (contain) in Lake Huron—go?

The answer is that the Himalaya, for example, long defined by    7    (it) glaciers,is becoming a mountain range defined by lake. In fact, another study found that from 1990 to 2010, more than 900 new glaciers-fed lakes     8    (form) across Asia's high mountain ranges.Because of those remote locations scientists must rely    9    satellites to count them ,and new lakes appear to be growing so quickly that it's difficult for scientific teams to agree on the precise number. I's all happening much    10    ( fast) than we expected it to even five or ten years ago.

9 . Melbourne Girls' College is getting rid of all dustbins and asking students to take their rubbish home to encourage them to move towards zero waste.
