A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.

1.What does the underlined word "unaltered" in paragraph 3 refer to?

A.Unchanged. B.Undivided.

C.Unadopted. D.Unfinished.

2.Why do mosquito populations have to be controlled?

A.Mosquitoes cause genetic changes in humans.

B.Mosquitoes spread some deadliest diseases.

C.Mosquitoes limit people's ability to reproduce.

D.Mosquitoes make traditional vaccines ineffective.

3.What has been the most successful way of reducing mosquito numbers?

A.Editing genes in female mosquitoes.

B.Sterilizing male mosquitoes before mating.

C.Limiting both genders' reproduction ability.

D.Using pesticides and removing stagnant water.

4.What can we learn from Stephen Dobson's words?

A.The things described in this paper are not practical.

B.A better way of mosquito control is yet to be found.

C.Xi Zhiyong' s method has proven to be very effective.

D.A new tool is needed in order to improve Xi's research.

Scientists in Canada say big fish have almost disappeared from the world since the start of industrial（产业的） fishing in the 1950s. The scientists found the numbers of some kinds of large fish have dropped by ninety percent in the past fifty years.

The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.

The scientists say the common method called long line fishing ravages the populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.

Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.

The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.

Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer big fish, but also they are smaller than those of the past.

There are around 600,000 vegans (素食者) in the UK. That' s just over 1% of the population — an amount expected to increase to 25% by 2025. And if there's one type of food that Brits love, it is fast food. People in the UK love it so much that there was a 34% increase in the number of fast food outlets from 2010 to 2018.

Vegan fast food has become big business. At Just Eat, an online food delivery company, vegan orders more than doubled in 2018. Greggs, a chain of high-street bakeries, named its vegan sausage roll the ''fastest - selling product in six years". And big franchises such as McDonald's and KFC have announced meat-free chicken nuggets (鸡块) to come in the future.

What's. driving this popularity? Katrina Fox, founder of Vegan Business Media, believes it's the result of the breaking down of stereotypes (成见). ''Vegan food is no longer seen as a bit of lettuce and lentils — you can eat pretty much anything".

It's also claimed that there are health benefits. John Marulanda, owner of Mooshies is a vegan burger bar in London — wants to implement “a change to a healthy version of fast food. Something, he claims, that comes as a result of the inherent nutritional value of the ingredients they use.

But, is vegan fast food actually healthy? Azmina Govindji of the British Dietetic Association says ''not to assume" that is the case, ''It' s fine if those products have got vitamin B12, iodine or calcium added to them. but they can still be fried, it can still have lots of creamy, fatty sauces and lots of salt.

Given the current growth in orders, the trend for vegan fast food isn't likely to disappear any time soon, Health — wise, it may not be any more nourishing than regular fast food, but for many， the lack of animal suffering involved in the process is a big plus.
