The first known dictionary was written in ancient Sumer around 2300 BCE, but it only included words for plants and animals. In 1604, Robert Cawdrey published A Table Alphabeticall in England, which was the first English dictionary with over 3,000 words. Unlike modern dictionaries, it didn’t have detailed definitions—only short explanations for hard words. Today’s dictionaries are much more comprehensive. The Oxford English Dictionary (OED), for example, has over 600,000 entries and includes word histories, pronunciations, and example sentences. It took over 70 years to complete the first edition of the OED! Now, many people use online dictionaries like Cambridge Dictionary. These digital tools can play audio pronunciations, show real-time word usage, and even translate words into multiple languages. Some experts predict that future dictionaries will use AI to personalize content. For instance, if a student often looks up science words, the dictionary might suggest related terms or explain concepts in simpler language. However, traditional paper dictionaries won’t disappear completely—many people still prefer flipping through pages to learn new words. ( ) 1.

Here are some useful tips. First, choose the right dictionary. For middle school students, a learner’s dictionary like Longman Dictionary of Contemporary English is best. It has simple definitions, example sentences, and notes on grammar and usage. Avoid advanced dictionaries—they have too many difficult words and may confuse you. Second, pay attention to word families. When you look up "care", don’t just read the definition of the noun. Check the verb ("care"), adjective ("careful"), and adverb ("carefully") too. This helps you understand how the word is used in different sentences. For example, "She cares about animals" (verb) and "Be careful when crossing the street" (adjective) show different forms of "care". Third, use the example sentences. Good dictionaries provide sentences to show how words are used in real life. If you look up "delicious", you might see "The cake tastes delicious". Try making your own sentence with the word, like "My mom’s cooking is delicious". This helps you remember the word better. Finally, note down new words. When you find a useful word, write it in a notebook with its definition and an example sentence. Review the notebook every week—this way, you won’t forget the words you’ve learned. ( ) 1.

In 1913, Cambridge University Press began planning an English dictionary for non-native speakers. At that time, most dictionaries were made for native speakers and had complex explanations. The first edition of the Cambridge English Dictionary came out in 1995. It was different from other dictionaries because it used a "defining vocabulary"—only 2,000 common words to explain all entries. This made it easier for non-native speakers to understand. For example, the word "ambitious" was defined as "wanting to be successful, rich, or powerful", instead of using hard words like "aspirational". Over the years, the dictionary has been updated many times. In 2010, it added over 1,000 new words, including "blog", "download", and "text message". These words became popular with the rise of the internet and mobile phones. In 2020, the online version added AI features—if you type a sentence with a new word, it can tell you if you used the word correctly. Today, the Cambridge English Dictionary has over 140,000 entries and is used by students and teachers in more than 100 countries. It continues to change with the times, making sure it stays useful for English learners around the world. ( ) 1. When did Cambridge University Press start planning the Cambridge English Dictionary?

One big advantage is c 1 —you can use them on your phone or computer anywhere, like on the bus or at home. You don’t have to carry a heavy paper dictionary. Another advantage is that they are always u 2 . New words like "metaverse" or "NFT" are added to online dictionaries quickly, while paper dictionaries take years to update. However, online dictionaries also have problems. First, they can be d 3 . If you don’t have internet, you can’t use them. Second, some online dictionaries have u 4 information. Not all websites check their content carefully, so you might get wrong definitions. Finally, using online dictionaries can be a distraction—you may end up playing games or watching videos instead of studying. So, what’s the best way to use online dictionaries? Use them when you need quick access to new words, but always check the information with a reliable dictionary like the Oxford Learner’s Dictionary. And remember to stay focused—don’t let other apps take your attention away from learning. 1. c______ 2. u______ 3. d______ 4. u______ 5. r______ （二）The First Chinese-English Dictionary The first Chinese-English dictionary was created by Robert Morrison, a British missionary, in the early 19th century. Before that, there were no good tools for Westerners to learn Chinese. Morrison arrived in China in 1807. He spent 12 years working on the dictionary. He collected Chinese words from books, newspapers, and conversations with local people. He also studied Chinese grammar carefully to make sure his explanations were c 1 . The dictionary was called A Dictionary of the Chinese Language and was published in three volumes. It included over 40,000 Chinese characters and their English translations. At that time, the dictionary was very useful for Western traders and missionaries. It helped them communicate with Chinese people better. However, the dictionary had some mistakes. For example, some characters had incorrect pronunciations because Morrison didn’t have enough local teachers. Also, some translations were not accurate—they were based on his own u 2 of Chinese culture, which was limited. Even so, Morrison’s dictionary was a big success. It laid the foundation for future Chinese-English dictionaries. Today, his work is still studied by historians who are interested in the history of language exchange between China and the West. 1. c______ 2. u______ 3. v______ 4. a______ 5. e______ 四、回答问题（20分） （一）How Dictionaries Help Students Learn English Dictionaries are essential tools for English learners. Here’s how they support students’ learning. First, dictionaries help students understand new words. When reading a story or article, students often encounter words they don’t know. A dictionary tells them the definition, so they can keep reading without stopping. For example, if a student sees "The girl was reluctant to go to bed", looking up "reluctant" (meaning "not wanting to do something") helps them understand the sentence. Second, dictionaries improve students’ writing. When writing an essay, students may want to use better words. A dictionary can suggest synonyms—words with similar meanings. For instance, instead of using "good" many times, a student can look up synonyms like "excellent", "great", or "wonderful" to make their writing more interesting. Third, dictionaries teach pronunciation. Most dictionaries use phonetic symbols (like /rɪˈlʌktənt/ for "reluctant") to show how to say a word. Some online dictionaries even play audio, so students can hear the correct pronunciation. This helps them speak English more clearly. Finally, dictionaries help students learn about word usage. They tell students if a word is formal or informal, and which prepositions to use with it. For example, a dictionary might note that "depend" is often used with "on" (e.g., "I depend on my parents"). This prevents students from making grammar mistakes. 1. What does a dictionary tell students when they encounter a new word? 2. How can dictionaries improve students’ writing? 3. What do phonetic symbols in a dictionary help students do? 4. What information about word usage can dictionaries provide? 5. Give an example of a preposition used with the word "depend". （二）The Future of Dictionaries As technology develops, dictionaries are changing rapidly. What will they be like in the future? Experts say future dictionaries will be more interactive. Instead of just reading definitions, students will be able to practice using words in games. For example, a dictionary app might ask students to fill in the blank: "She ______ (care) about her friends" (answer: cares). This makes learning more fun and helps students remember words longer. Another trend is personalized dictionaries. AI will track the words students look up most often and create custom word lists. If a student often looks up sports words, the app might suggest related terms like "goal", "team", or "champion". It might also give practice exercises based on the student’s weak areas. Future dictionaries will also connect to other learning tools. For example, if a student reads an article on a news app and doesn’t know a word, they can click the word to see its definition in the dictionary app—without switching between apps. Some dictionaries might even work with virtual reality (VR) headsets. Students could "walk" through a virtual world and learn words by interacting with objects (e.g., seeing a "cat" and hearing its pronunciation). However, experts also say that the core function of dictionaries—helping people understand and use words—will never change. No matter how advanced technology gets, dictionaries will always be important for language learning. 6. What kind of games might future dictionary apps have? 7. How will AI create personalized dictionaries? 8. What example of a custom word list is given in the passage? 9. How might future dictionaries connect to news apps? 10.
