【题目】 Do you think robots could pass an eighth-grade test? Guess what—they can.
The artificial intelligence (AI) system Aristo recently passed the same eighth-grade science test that some US students take. The New York Times reported. Aristo correctly(正确地) answered 90 percent of the questions on the test.
This is an example of the progress that is being made in AI development. Four years ago, 700 computer scientists tried to develop AI systems that could pass these kinds of exams. None scored higher than 60 percent.
Scientists at the Allen Institute in the US developed the system. Aristo was able to pass the exam because it can not only understand language, but also use logical thinking(逻辑思维)to solve difficult problems. For example, it can understand what a forest fire is and how it could affect(影响) animals.
The system used BERT, a kind of neural(神经的) network technology developed by Google, to answer the questions. BERT has "read" thousands of articles and can understand English. If it looks at a sentence with a missing word, it can correctly guess what the word is. With BERT's help, Aristo "read" many multiple-choice(多选的) questions. Over time, it was able to find logical patterns(逻辑模式).
Aristo’s success means that we might see new AI-based products(人工智能产品), such as search engines(搜索引擎) and databases(数据库) for hospitals. AI systems might be able to better understand users in the future.
【1】What did the AI system Aristo do?
A.Help students study.B.Pass a school test.
C.Talk like a human does.D.Develop other AI systems.
【2】What was Aristo's biggest success?
A.It passed several kinds of tests.B.It passed the test with a full score.
C.It scored 90 percent on the test.D.It worked out a set of test questions.
【3】How did Aristo answer questions in the test?
A.By using BERT.B.By asking Google for help.
C.By working with scientists.D.By copying the students' answers.
【4】Paragraph 5 is written to________.
A.explain how Aristo workedB.show what else Aristo can do
C.show how Aristo was createdD.describe another AI breakthrough
【5】From the story, we can learn that________.
A.AI-based products are not usefulB.AI systems might be used in many fields
C.robots can't think logicallyD.Aristo will be used to help teach students
