It is cold and     1    (wind) in Moscow and snow is still on the ground. But none of that discourages visitors to the famous Moscow Zoo. They want to see     2     zoo’s two biggest stars: Ru Yi and Ding Ding.

During the summer, more than 30,000 visitors come here on an average day. Even during off-peak parts of the year, there is always a crowd     3     front of the Panda House. Since     4    (they) arrival, the two pandas have been the stars of the Moscow Zoo, attracting thousands of visitors interested to see them, which are among the     5     (rare) animals in the world.

Pandas’ reproductive rate is     6    ( extreme) low. Females normally give birth     7     one or two cubs(幼崽). If twins are born, the mother may only raise the stronger of the cubs. A newborn panda baby only     8    (weigh) about 0．1 percent of the weight of a fully grown panda,     9    (make) its survival very difficult.

China and Russia agreed     10    (let) both pandas stay here until 2034, part of a 15-year scientific program. Very soon, Ru Yi and Ding Ding that have been kept in separate suites will be introduced to each other. And the people of Moscow Zoo hope nature will take its course and that baby pandas will be born here soon after.

Something is happening to the British. They seem to be developing green fingers! The number of people growing their own fruit and vegetables     1     (increase) in the past year, according to Gardeners’ World.

Gardens and private land for vegetables and fruit across the UK have been put to use with people’s     2     (discover) of the joys of home-grown produce. But not everyone has space for a vegetable land or a flowerbed. And sometimes a window box just isn’t enough for     3     gardening challenge. This is why people plant flowers or vegetables in public spaces to make them     4     (green) and more pleasing to the eye.

Many people would approve     5     beautifying towns and cities, but this type of gardening is not     6     (strict) legal. Therefore, the special gardening often takes place late at night. But the image of the enthusiastic gardener is not someone     7     breaks the law. It is of someone spending all their time in     8     (greenhouse) and potting sheds (育秧棚), a person knowing every aspect of how to tend and grow the plants.

Yet, despite the increase in people growing their own, half of the UK population     9     (be) still puzzled about when most fruit and vegetables are in season, according to Gardeners’ World. It seems that Britain still has a long way     10     (go) before being called a nation of gardeners

Many people think rock-life forms in the sea filled with colourful fish when corals(珊瑚) are mentioned. But corals are made up of thousands of small organisms     1     live and feed like any other sea life.

Researchers in Hawaii and Australia have been engineering corals inside a lab for the past five years to see if they could better resist the     2     (effect) of climate change. They say it is now time     3     (see) how their creations perform in nature. The climate change already     4     (lead) to warming oceans that can harm sea life. If the more heat-resistant corals researchers developed do     5     (good) in the ocean, the method can     6     (use) to help save suffering and dying reefs. The team tested three methods for     7     (make) corals that would be strong and healthy in nature. Hughes, the leader of the project, said all the methods proved     8     (success) in the lab. Some scientists might worry such methods go against the natural processes of nature. But with the planet continuing to be warmer and warmer, scientists don’t see any better     9     (choose). “We have to do something     10     order to make a change for coral reefs to survive into the future, ” Hughes said.

Environmental problems are significant in many people’s minds, but it’s     1     younger generation who is particularly concerned about the future of our planet. From global school strikes for climate change action     2     amazing teen activists, kids are now taking it into their own hands.    3     (promote) this love for the earth, a new bill that requires students to plant 10 trees each before graduation     4     (pass) in the Philippines on May 15, 2019. In the past years, the Philippines     5     (lose) more than 30% of its forest cover. But 175 million trees could be planted by students each year under the     6     (fantasy) program, which means the students in the Philippines can help improve the situation. The action of planting 10 trees is an     7     (extreme) easy task for the average student: a kid graduating from elementary school, a teen graduating from middle school, a young adult graduating from college — but their small actions will add up quickly to work wonders.

In fact, this isn’t the only positive program     8     (involve) the younger generation. Some schools in India made students pay their “school fees” by collecting, bringing to school and recycling any plastic waste     9     was lying across the town. This type of activity has helped raise     10     (aware) of plastic waste in Asian countries.

There is strong and comprehensive evidence that the rise in temperature     1    (lead) to an increase in extreme weather and natural disasters worldwide, causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will     2    (probable) continue and there will be a higher price     3    (pay). In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves     4    (cause) deaths and economic losses.

Continued greenhouse gas emissions will result     5    further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making     6    (policy) and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting     7    amount of carbon dioxide our lifestyles produce. It is our responsibility     8    (seize) every opportunity to educate everyone about global warming, along with its causes and     9    (impact), because this is the most serious issue affecting all of us on this planet. So     10    will you do to help?

The size of fish in the oceans is shrinking. A new report from Canada states fish may shrink by as much as a quarter in the coming decades,     1     mainly results from global warming. The research team concluded tests on the impact of rising ocean temperatures on the size and number of over 600species of fish. They concluded that most fish are likely to shrink by 14-24 percent by the year 2050.The biggest changes     2     (see) clearly in tropical regions. There is     3     (little) oxygen in warmer water so fish cannot grow normally and many will migrate to cooler waters. Lead researcher Professor William said, “we were surprised to see such a large decrease in fish size. Marine fish are     4     (universal) known to respond to climate change by changing distribution(分布) and seasonality. But     5     unexpectedly big effect that climate change could have     6     body size suggests that we may be missing a big piece of the puzzle of understanding climate change effects in the ocean.” He added that overfishing and pollution will     7     (worse) the problem. “Our work shows a very     8     (worry) future for the oceans,     9     it is very import ant to reduce greenhouse gas emissions and develop better fish management policies     10     (adapt) to these changes,” he said.
