First Image-recognition Software
1. Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.
2. The new system, which was tested on photos and is now being applied to videos, shows for the first time that a machine learning algorithm (运算法则) for image recognition and retrieval is accurate and efficient enough to improve large-scale document searches online. The system uses pixel (像素) data in images and potentially video — rather than just text — to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search engines. The knowledge gleaned (收集) from those results can then be applied to other photos without tags or captions (图片说明), making for more accurate document search results.
3. "Over the last 30 years," says Associate Professor Lorenzo Torresani, a co-author of the study, "the Web has evolved from a small collection of mostly text documents to a modern, massive, fast-growing multimedia data set, where nearly every page includes multiple pictures or videos. When a person looks at a Web page, he immediately gets the gist (主旨) of it by looking at the pictures in it. Yet, surprisingly, all existing popular search engines, such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Web pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search."
4. The researchers designed and tested a machine vision system — a type of artificial intelligence that allows computers to learn without being explicitly programmed — that extracts semantic (语义的) information from the pixels of photos in Web pages. This information is used to enrich the description of the HTML page used by search engines for document retrieval. The researchers tested their approach using more than 600 search queries (查询)on a database of 50 million Web pages. They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages. They found that this produced a 30 percent improvement in precision over the original search engine purely based on text.
23. Paragraph 1 ____
24. Paragraph 2 ____
25. Paragraph 3 ____
26. Paragraph 4 ____
A. Function of the new system
B. Improvement in document retrieval
C. Publication of the new discovery
D. Problems of the existing search engines
E. Popularity of the new system
F. Artificial intelligence software created
27. The new system does document retrieval by ____.
28. The new system is expected to improve precision in ____.
29. When performing document retrieval the existing search engines ignore __ __
30. The new system was found more effective in document search than the ____
A. using photos
B. description of the HTML page
C. current popular search engines
D. document search
E. information in images
F. machine vision systems

大学英语A级是专科生中较为优秀的英语水平级别，考试难度高于B级但低于大学英语四级，对于认真备考的考生来说并不会非常难考。以下是关于大学英语A级考试的详细解答：
一、考试级别 大学英语A级是针对专科生设立的英语水平考试，其难度高于B级，是专科生中较为优秀的英语水平体现。
二、考试难度 相对于大学英语四级而言，A级的难度较低，但高于B级和初中到高中的英语水平。 与公共英语三级相比，A级的难度略高于公共英语三级，但仍属于可通过系统学习掌握的范畴。
三、考试内容 大学英语A级考试涵盖词汇、语法、阅读、听力和写作等方面，注重语言的实际运用能力。 考生需要熟练掌握英语的基本语法和词汇，并具备一定的阅读和听力理解能力。

英语A级考试语法学习需结合题目实践，重点掌握高频语法点，通过标注句子成分和背诵例句提升解题能力。
语法学习的重要性语法是理解句子的基础，尤其在阅读和完型填空中，长句分析依赖语法知识。例如，通过划分主语、谓语、宾语等成分，可以快速把握句子核心意思，避免因结构复杂导致理解偏差。
高频语法点
独立主格结构：常用于描述伴随状态或条件，例如“Weather permitting, we will go hiking.”（天气允许的话，我们去徒步。）
倒装句：包括部分倒装（如否定词开头时“Never have I seen such a beautiful sunset.”）和完全倒装（如地点状语开头时“Here comes the bus.”）。
三大从句：
定语从句：需明确先行词及关系词（如“The book that I bought yesterday is very interesting.”中的“that”指代“book”）。
答案与题解:
1. B A 选项 grounds 意为"理由，基础" ;C 选项 causes 意为"原因" ; D 选项 purposes 意为"目的;意志"。根据句意"城墙一方面是为了防御外敌……" for 为介词，表目的。for de***sive reasons，为了防御的原因。故选 B。
2. D 考查固定搭配。A 选项 injuries 意为"伤害，受伤";B 选项 symptoms 意为"症状";C 选项colds 意为"感冒";D 选项 contagious diseases 意为"传染病"。根据句意应选 D。
3. B 此句句意为"伦敦古城的城门，均在 18 世纪末被拆毁。"A 选项 devoted 意为"献身于……";B 选项，demolished 意为"拆毁，破坏"，与句意相符;C 选项 declared 意为"公然的,公开宣布的";D 选项 decreased 意为"减少"。故选民
4. A 考查固定搭配 a stroke of luck。
5. C 考查固定搭配in actual fact,为固定搭配，意思是"事实上"。等于 actually或 as a matter of fact 。
