【推荐2】Perhaps the most common climatic effect of global warming is rapid extension of ice melt. Mount Kilimanjaro in Africa and the Himalayas will very likely lose most of their glacial ice within the next two decades, affecting local water resources. NASA scientists determined Greenland’s ice sheet is thinning by about 1m per year. The additional melt water, especially from continental ice masses and glaciers, is adding to a rise in sea level worldwide. Satellite remote sensing is monitoring global sea level, sea ice, and continental ice. Worldwide measurements confirm that sea level rose during the last century.

Okay, so how much is melting of Greenland contributing to sea level rise? Estimates are about 270 gigatons of water per year. The melting of an ice sheet can occur from the surface as air temperatures and sunlight warm the upper layer of ice. It can also occur from the edges as ice shelves collapse and fall into the oceans in large pieces. The bedrock underneath the ice sheet is not also flat. There are undulations that rise and fall and change the water-ice-ground connection, which can make it easier for ice to melt and can increase the rate of ice shelf collapse. So scientists have a real interest in learning about the land underneath ice sheets so that they can better predict ice collapse and sea level rise.

Greenland ice has its feature, meaning it acts slowly but once it gets going, it’s hard to stop. So predicting how fast this melt will take is interesting from a scientific advantage point but there are also enormous social and economic consequences. Right now, 150 million people live within 3 feet of today’s sea level. If you live near the coast, the question of “when” is really important. This suggests that “when” may be sooner than we hoped.

【推荐3】Experts say that if food were a country, it would rank second behind the US as one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for14.5 percent of global greenhouse gas methane(甲烷) emissions(排放). While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.

Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources, While going vegetarian(素食的)would help meat consumption too deep - rooted in most western diets to allow for such a sharp, permanent change. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects！

Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic(驯养的) animals. They also require much less room，use less water and food, and produce far less greenhouse gas than animals

Of the 1.1 million insect species worldwide, scientists have identified 1.700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat

While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated(饱和)at found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup make baked treats, and even fry a few with vegetables. So eat insects -both your body and Mother Earth will thank you for it ！

【推荐1】Digital technology — email and smart phones especially — have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey (调查) of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it and only 35 percent say it’s tolerated.
Skeptical bosses will likely have their doubts reinforced (加深) by the same survey, which shows that 43 percent of workers say they’ve watched TV or a movie while “working” remotely, while 35 percent have done housework，and 28 percent have cooked dinner.
It is true, however，that working at home makes people much more efficient (高效的)， because it allows workers to take care of annoying housework while still getting their jobs done. It’s much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush.
The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker.
More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who have worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility to manage their time efficiently.
1. Why do some employers hesitate to allow remote working?

A．They fear losing control of their workers.

B．They want to stick to their routine practice.

C．They have little trust in modem technology.

D．They are used to face-to-face communication.

2. What seems to be most workers’ attitude toward remote working?

A．Doubtful.

B．Favorable.

C．Reserved.

D．Disapproving.

3. What does the author suggest smart firms do?

A．Shorten their office hours.

B．Give employees a pay raise.

C．Adopt flexible work patterns.

D．Reduce their staff’s workload.

【推荐2】Eastern barred bandicoots (袋狸) once were a common sight in the plains of western Victoria and into South Australia. But by the 1980s, just one population of between 150 and 200 bandicoots survived.

In 1988, the Victoria state government formed a recovery team that brought together government agencies, Zoos Victoria, volunteer groups and other people. That year, scientists removed 40 bandicoots from this population to form a captive breeding (圈养繁殖) program. Soon after, eastern barred bandicoots disappeared from the wild in Victoria. The only remaining breeding population existed in small pens at Woodlands Historic Park. “Without the captive program, the species would be extinct.” Scientists say.

Breeding was one thing. Re-establishing wild populations was altogether more difficult. Six times captive-born bandicoots were set free into the wild. All six reintroductions failed when foxes killed the bandicoots.

What changed everything was the reintroduction of bandicoots to Phillip Island in 2017 and French Island in 2019. Fox-free French and Phillip islands offered just over 70 square miles of bandicoot habitat, and the bandicoots have already begun breeding and expanding (扩大) their range across these islands.

After scientists had established populations on islands, researchers looked to expand their efforts to open grasslands. In 2015, David Williams began training his Maremma dogs. The idea worked this way: Because bandicoots live alone, the Maremmas would look after sheep in large open grasslands where bandicoots lived. As long as there were sheep in the bandicoots’ territory (领地), the Maremmas remained, and as long as the dogs were around, the foxes were far less likely to remain.

Over the past two years, the recovery team has reintroduced 40 bandicoots into two places in western Victoria, with two to three Maremmas and hundreds of sheep at each site to keep them company. Scientists can’t yet say whether the experiment is working. But some of the bandicoots have bred, and initial camera-trap evidence suggests that foxes, if they pass through the area at all, rarely stay for long.

1. What is the main idea of Paragraph 2?

A．Eastern barred bandicoots became extinct in the wild.

B．The 1988 captive breeding program saved the species.

C．The government played a role in protecting the species.

D．Combined efforts made no difference to the environment.

2. What led to the failure of all 6 bandicoot reintroductions?

A．Food shortage.

B．Lack of habitats.

C．Threats of natural enemies.

D．Insufficient captive-born bandicoots.

3. Why did William train Maremma dogs?

A．To take good care of his sheep.

B．To keep bandicoot out of fox territory.

C．To help dogs and bandicoots live in harmony.

D．To reintroduce bandicoots to the open grasslands.

4. What can be inferred about the program in western Victoria?

A．It has completely failed.

B．Its result remains to be seen.

C．It turns out an instant success.

D．Its process needs closely monitoring.
