Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.
The experts believe the machine should be able to collect half of the detritus in the patch – about 40,000 metric tons – within five years. In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine, creating the largest floating barrier ever made。
The system, originally dreamed up by Mr. Slat, will be shipped out this summer to the Great Pacific Garbage Patch, between Hawaii and California, and which contains an estimated 1.8 trillion pieces of plastic. It will be the first ever attempt to tackle the patch since it was discovered in 1997.
Mr. Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea. “There were more bags than fish down there,” he recalls. Two years later he came up with a solution, quit university after six months and set up The Ocean Cleanup as a company. Mr. Slat, 23, says the first plastic to arrive on shore will be a major milestone. “We as a humanity created this problem, so I think it's our responsibility also to help solve it,” he said.
The Great Pacific Garbage Patch (GPGP) spans 617,763 sq miles - more than twice the size of France, and contains at least 79,000 tons of plastic, research found last month. Most of it is made up of “ghost gear” – parts of abandoned and lost fishing gear, such as nets and ropes – often from illegal fishing vessels.
Ghost gear kills more than 100,000 whales, dolphins and seals each year, according to scientific surveys. Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic. Creatures eat plastic discarded in the sea thinking it’s food but then starve to death because they are not feeding properly. Others are trapped and die of starvation or are strangled or suffocated by ghost gear.
1.What does the underlined word in the first paragraph probably mean?
A. waste. B. ocean.
C. system. D. machine.
2.According to the passage, most of the Garbage in Pacific is made up of _____ .
A. fishing vessels
B. dolphins and seals
C. giant tubes
D. abandoned fishing gear
3.why do some creatures in The Great Pacific Garbage Patch die of starvation?
A. because they were killed by Ghost gear.
B. because they were suffocated by ghost gear.
C. because they didn't like eating plastic.
D. because they are not feeding properly.
4.What is the main idea of the Passage?
A. news about the first machine to clean up ocean plastic.
B. report about the death of marine life
C. information about ocean plastic.
D. the reason for inventing a machine.

A company has just launched what it calls “the world’s first free standardized English test” recently. Anyone can take the test for free. The new exam is called the EFSET, which is short for Education First Standardized English Test. The company, Education First, is known by the letters EF.
It is estimated that there are two billion English language learners worldwide. Many of them are interested in attending an American college or university. To do so, foreign students need to take the Test of English as a Foreign Language — better known as TOEFL. However, many foreigners are not wealthy enough to take the TOEFL. In addition, test-takers often have to travel overnight to reach an official testing site. The World Bank says an average Cambodian worker earns only about $1,000 per year. Approximately the cost of taking the TOEFL is 17.5 percent of the average worker’s yearly wage.
It is not just individuals who find the test pricey. Some governments also find it prohibitive. What’s more, not everyone needs official results from the TOEFL or IELTS — the International English Language Testing System. In the future, it’s likely that the government may use the EFSET to test millions of employees and students.
Experts believe that the EFSET meets the highest value in language testing. It uses special computer software that makes the questions easier or harder, depending on one’s performance. The EFSET measures all the English learners’ levels while the IELTS and TOEFL only measure learners’ levels from moderate (中等的) to advanced. The EFSET is unique in the sense that it gives free online access to anyone interested in measuring their English level.
There is a 50-minute and a two-hour version of the test, which its developers are calling the EFSET Plus. Both versions test only reading and listening skills. It’s hopeful that speaking and writing skills will be tested in the future. The IELTS and the TOEFL still use humans to rate the speaking and writing sections. It’s a huge deal for students who are in areas where they can’t get to the TOEFL or the IELTS. However, it is too early to know whether the EFSET results are acceptable for colleges and universities in America.
1.Why do many foreign students take the TOEFL?
A. To learn English well.
B. To be admitted to key universities.
C. To receive further education in America.
D. To find good jobs and earn much money.
2.What can we infer from Paragraph 2?
A. Only wealthy people can take the TOEFL.
B. The cost of taking the TOEFL is very high.
C. There are many official testing sites for the TOEFL around the world.
D. Few of the students in Cambodia can afford to take the TOEFL.
3. What can we learn about the EFSET?
A. It is similar to the TOEFL and the IELTS.
B. Everybody with different English levels can take it for free.
C. It tests the skills of reading, listening, writing and speaking.
D. American universities accept the EFSET results for admission.
4.What’s the best title for the passage?
A. How to get ready for the EFSET
B. Different ways to test English learners in the world
C. The new software developed by Education First
D. The free EFSET— an online test for English learners

In 1992, I had just launched a new business called Video News International.
It was the world's first video journalist network. The idea was to cover news and sell the service to news organizations.
One day, a young intern (实习生) who was working for us named Anthony Lappe pulled me aside.
"There is something you have to see," he told me. "Comcast is doing this really cool thing."

Scientists at Israel's Tel Aviv University say—they have created the world’s first 3D-printed heart with human tissue and blood vessels. Although the organ is only as big as a rabbit’s heart, the researchers are hoping the technology could one day be developed enough to help human patients in need of a heart transplant.
Lead researcher Tal Dvir said that while other scientists have managed to 3D—print the structure of a heart in the past, this is the first time anyone has printed an entire heart. “Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future,”Dvir said in a press statement.
Scientists used fatty tissue taken from human patients to create the heart. Some material in the tissue was reprogrammed to become stem cells. The remaining material was processed into a hydrogel. They used the hydrogel as a printing：“ink”. This method is key to removing the risk that the implant will be rejected by the patient’s body. The team’s next step is to cultivate the organs in a lab and to teach them how to“behave”like hearts. Dvir’s 3D-printed hearts can currently contract, but the cells still need to develop a pumping ability. His team eventually plans to test the hearts in animals.
“Maybe, in ten years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely, ”Dvir said. Heart disease is the leading cause of death for both men and women, according to the Centers for Disease Control and Prevention. About 610, 000 people die of this disease in America every year—amounting to about 1 in every 4 deaths. There are currently more than 3700 people waiting for a heart transplant in the United States, according to data from the United States Department of Health and Human Services.
1.What is the purpose of creating the 3D-printed heart?
A.To develop 3D-printed technology. B.To study the hearts of rabbits.
C.To connect hospitals with universities. D.To help patients receive a new heart.
2.Why does the author mention the current situation of heart disease patients?
A.To appeal to hospitals to reduce medical fees.
B.To show the need to improve the new technology.
C.To urge researchers to develop effective medical devices.
D.To introduce the main reason for heart disease to the public.
3.What is the third paragraph mainly about?
A.The course of the research. B.The importance of the research.
C.The material of the 3D-printed heart. D.The method of the 3D-printed heart.
4.What’s Dvir’s attitude towards the new technology?
A.Disapproving. B.Doubtful.
C.Positive. D.Indifferent.
