A great number of species make their home in the vast waters of the Atlantic Ocean. Although the entire ocean makes up an ecosystem, many smaller habitats are found within, including an open-water habitat off the coast of the Northern Atlantic Ocean known as the Sargasso Sea. Sargassum is an alga(海藻) that floats in masses that can continue for miles. The waters of the Gulf Stream push the water in a northward move into this area. This constant move and varying temperature support the accumulation of the brown-colored seaweed.
The Sargasso Sea is so enormous that one method of information collection has not been enough for scientists to obtain an accurate picture of what takes place within this ecosystem. Researchers have needed to employ several methods of sampling. Methods such as dragging nets over the surface of the water and videotaping beneath areas of sargassum have served scientists well.Information collected has shown that the Gulf Stream pushes brown algae from open water into the Sargasso Sea area, creating a diverse floating habitat in an area that would otherwise not support that wildlife.
In the most recent study of the sargassum community off the shores of North Carolina, eighty-one fish species were documented as using the area as a microhabitat.This is an increase from previous studies. The types of fish found here are both commercially and environmentally important.The South Atlantic Fishery Management Council is working to regulate the harvesting of sargassum. The Council hopes to have the area classified as an Essential Fish Habitat. Which would afford it certain protections.
Further research needs to be done before scientists understand how to best protect the Sargasso Sea as well as understand how it goes about supporting so many important types of wildlife.
1.The author uses “enormous” in paragraph 2 to stress that .
A.the Atlantic Ocean is really amazing in terms of its size and area
B.what the researchers do is highly respected by scientific community
C.the research work is complex because a large area must be covered
D.a large amount of money for the Sargasso Sea research is needed
2.It can be inferred from the phrase“needed to be done”in paragraph 4 that the author thinks .
A.the Sargasso ecosystem is worth our attention and needs more study
B.the scientific community has ignored this complex ecosystem
C.the Sargasso Sea is becoming a problem and needs removing
D.new methods for researching the ecosystem must be found instantly
3.The text is mainly about .
A.diversity of wildlife in the Atlantic Ocean

高三英语单项填空简单题查看答案及解析
In order to help cope with the vast number of student questions in the online class, Knowledge-Based Artificial Intelligence, Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn’t enough to handle the vast number of daily questions from students.
Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.
Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustment and ample time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.
The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier forecast on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.
1.What do we learn about Knowledge-Based Artificial Intelligence?
A.It is a robot that can answer students’ questions.
B.It is a high-tech device that revolutionizes teaching.
C.It is a course designed for students to learn online.
D.It is a computer program that aids student learning.
2.What does the underlined word “remedy” in the paragraph 2 mean?
A.Boycott. B.Improve. C.Evaluate. D.Corrupt.
3.What do we learn about Jill Watson?
A.She was unwelcome to students at first.
B.She got along pretty well with students.
C.She turned out to be a great success.
D.She was released online as an experiment.
4.What does Professor Goel plan to do next with Jill Watson?
A.Assign her to answer more of students’ questions.
B.Upgrade her intelligence to the level of top scientists.
C.Launch different versions of her online.
D.Encourage students to interact with her more freely.
