passage you have just read.

(A)

A Swedish power plant is taking reuse and recycle to the next level by burning unusable clothing instead of coal, Bloomberg reports.

Retail giant Hennes & Mauritz, more commonly known as H&M, is helping the utility transition away from coal through its moldy (发霉的) or otherwise unsalable clothing.

The multi-fuel power and heating station in V?ster?s, central Sweden, is planning to be completely fossil-fuel free by 2020. It?s the largest station of its kind and Sweden claims it?s one of Europe?s cleanest. To kick its coal habit, the station is turning instead to other burnable materials including recycled wood, rubbish and yes, clothes.

“Our goal is to use only renewable and recycled fuels,” Jens Neren, head of fuel supplies at the utility company which owns and operates the V?ster?s plant, told Bloomberg.

Johanna Dahl, head of communications for H&M in Sweden, told Bloomberg that the company allows only the burning of clothes which are no longer safe to use. “It is our legal obligation to make sure that clothes that contain mold or do not meet the requirements of our strict restriction on chemicals are destroyed,” she said.

The V?ster?s plant has burned around 15 tons of old H&M clothes so far this year, compared with about 400,000 tons of rubbish, Neren told Bloomberg.

Sweden has one of the world?s greener energy generating systems, and has invested in bioenergy, solar power and electric buses. In 2015, the Scandinavian country announced an ambitious aim to become one of the first nations in the world to end its dependence on fossil fuels. According to the Swedish government, the country has already heavily reduced its dependence on oil, which accounted for 75% of the energy supply in 1970, and now makes up a 20% share. 56. Which of the following can serve as fuel in the V?ster?s plant?

A. Fashionable coats in H&M chain store. B. Old TV sets deserted as rubbish. C. Wooden furniture in second-hand shop. D. H&M clothes unsuitable for sale. 57. The underlined word in the last paragraph “generating” is closest in meaning to

______.

A. eliminating B. adjusting

C. producing D. circulating 58. What can we learn from the passage?

A. The Swedish government discourages the development of bioenergy. B. Clothes only take up a small proportion of the burning material. C. Sweden?s fossil-fuel free plan is almost accomplished by now. D. Sweden has an ambition to be the cleanest country in the world. 59. What is the main idea of the passage?

A. A Swedish power plant is burning unusable H&M clothes for fuel. B. The Swedish government aims high and is taking effective action. C. H&M is looking for a new way to strengthen its position in fashion. D. Coal and oil are no longer regarded as the primary fuels in Sweden.

RAINFOREST ADVENTURE TIPS 1. Find out about the trail and surroundings, be sure that you have enough time to complete the entire route before darkness falls. Do not stray off the path to chase after animals. 2. Use good judgment regarding the fitness level required （徒步跋涉）, and know your physical limits. for the trek3. Always inform the park officials or let someone know of your plans and destination for the day, especially if going alone. 4. Take plenty of water and pack a few easy to eat snacks to keep energy level up. Unless trekking with a local guide, it is not advisable to eat jungle fruit or drink from any water source. 5. Be as quiet as possible to avoid scaring any wildlife. Getting an early start during the dawn provides the best chance to sight animals seeking food and the warmth of the early morning sun. 6. Wear thin, loose, preferably cotton clothing to remain comfortable. 7. Cover arms and legs with long trousers and long-sleeved shirts to ward off mosquitoes and to provide protection against thorny plants. 8. Be prepared for sudden rain showers by carrying a poncho that wraps over both body and your carrying pack to keep everything dry. 9. Choose footwear with proper ankle support and good traction. 10. A wide brimmed hat helps to shade a trekker from the heat of the tropical sun.

60. Before an adventure, a trekker should ______.

A. tell the park officials his destination and time schedule

B. pack up some jungle fruit juice and pre-cooked meals C. consult a local guide about the most adventurous route D. have his fitness level assessed at the tourist center

61. Which of the following is NOT suitable for a rainforest trekking? A. Long-sleeved cotton shirts. B. Tight sports shorts. C. Hiking boots. D. A wide brimmed hat. 62. If a trekker starts out at dawn, he may ______. A. escape being caught in the rain B. sight scared wildlife C. enjoy the heat of the tropical sun D. see animals seeking food (C)

The largest genetic study of mosquitoes has found their ability to resist insecticides is evolving rapidly and spreading across Africa, putting millions of people at higher risk of contracting malaria（疟疾）. British scientists who led the work said mosquitoes' growing resistance to control tools such as insecticide-treated bed nets and insecticide spraying, which have helped cut malaria cases since 2000, now threatens “to disturb malaria control” in Africa. “Our study highlights the severe challenges facing public efforts to control mosquitoes and to manage and limit insecticide resistance,” said Martin Donnelly of the Liverpool School of Tropical Medicine, who worked on the study with a team from Britain?s Wellcome Trust Sanger Institute.

Latest World Health Organization (WHO) data show that 216 million people were infected last year with the malaria parasite (寄生虫), which is transmitted by blood-sucking Anopheles mosquitoes.

The disease killed 445,000 people in 2016, and the majority of them were children in sub-Saharan Africa.

To understand how mosquitoes are evolving, the researchers sequenced the DNA of 765 wild Anopheles mosquitoes taken from 15 locations across eight African countries. Their work, published in the journal Nature on Wednesday, created the largest data resource on natural genetic variation for any species of insect.

Analyzing the data, the scientists found that the Anopheles gambiae mosquitoes （冈比亚疟蚊）were extremely genetically diverse （多样化的） compared with most other animal species. This high genetic diversity enables rapid evolution, they said, and helps to explain how mosquitoes develop insecticide resistance so quickly.

The data also showed the rapid evolution of insecticide resistance appeared to be due to many previously unknown genetic variants（变体）within certain genes. The scientists said these genetic variants for insecticide resistance were not only emerging independently in different parts of Africa, but were also being spread across the continent by mosquito migration.

Michael Chew, an expert at Britain?s Wellcome Trust global health charity which helped fund the research, said the finds underlined the importance of pushing scientific research ahead to control malaria.

Global efforts to control malaria through effective vaccine, insecticides and the best drug combinations require urgent, united action by scientists, drug companies, governments and the WHO.

63. Which of the following is scientists? headache?

A. The number of mosquitoes in Africa is growing rapidly.

B. Some genetic variants of mosquitoes are still unknown.

C. The existing insecticides aren?t as effective as they used to be.

D. Millions of African people have resistance to medicines for malaria. 64. Malaria cases can be cut by ______. A. threatening drug companies B. spraying insecticides C. limiting blood donation D. transmitting data

65. What CANNOT be concluded from the passage? A. Children are more likely to be bit by mosquitoes.

B. Many previously unknown variants are found in the study. C. The mosquito migration contributes to the spread of variants. D. Anopheles mosquitoes have great genetic diversity. 66. Which is FALSE about the genetic study of mosquitoes?

A. It created the largest data on natural genetic variation for any insect species. B. It found the possible causes for the rapid evolution of insecticide resistance. C. It discovered where the genetic variants emerged and how they were spread.

D. It highlighted the public efforts and appealed to limit the use of insecticides.

Imagine you're standing in line to buy an afterschool snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code with your smartphone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear. __________67__________ As technology companies move away from traditional password, biometric（生物识别） security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one’s fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since last year, Samsung has featured eye-scanning technology in its top smartphones, while Apple’s new iPhone X can even scan a user’s face.

But it’s already been done. In a video posted on community website Reddit on

Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they aren’t even twins.

“We may expect too much from biometrics,” Anil Jain, a computer science professor at Michigan State University, told CBS news. “No security systems are perfect.”

Earlier this year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smartphone for police.

“It’s good to see biometrics being used more,” Jain told CBS News, “because it

adds another factor for security. __________70__________”
