I already have the second edition of Longman s Advanced Contemporary Dictionary, do I need to buy a

longman dictionary of contemporary english（ldoce）

ldoce1 (1978) has the impression that the illustrations are very delicate, but the diagrams of a certain type are always grouped together, not as scattered as in the second edition, so that there are too many cross-references. The only big flaw in the first edition is that the grammar is abstract and complicated, which is puzzling. (Potentially controversial?)

ldoce2 (1987) has about 50,000 or 60,000 words, which is especially suitable for college students. In particular, it contains a lot of idioms, and it really feels like it's left and rightAnd unlike the Anglo-Chinese, they take all the idioms in various Anglo-American dictionaries, without screening;The arrangement is very compact, which makes people patiently read and at the same time gives people a pleasure like large beads and small beads falling on a jade plate.

ldoce3 (1995) was still very excited to see the color pages, in order to catch up with the 1995 dictionary publishing craze, the proofreading of "Longman Contemporary (3rd Edition)" was not rigorous enough, and there were some mistakes, such as misspelling and phonetic transcription.

The LDOCE4 (2003) CD-ROM version now contains many idioms or phrases that are not found in other dictionaries, which is useful for reading American and British newspapers.

The Longman Dictionary of Contemporary English (LDOCE) is one of a series of dictionaries launched by Longman Publishing. With its accurate and concise definitions, ldoce has been well received by readers, especially students, both in the UK and overseas. This is the 4th edition of lDOCE, and in addition to inheriting and retaining the features and advantages of the previous 3 editions, it also has the following significant features:

First, the number of words is large, and there are many new words. The 4th edition of LDOCE provides a comprehensive overview of the current state of the English language, with more than 106,000 words and phrases, more than 24,000 more than the 3rd edition supplement. In addition to some commonly used words, it also includes a large number of professional and encyclopedic vocabulary such as science and technology, humanities and social sciences, including many new words that have emerged in recent years, with distinctive characteristics of the times.

Second, the example sentences are rich and diverse, natural and authentic. The 4th edition of Ldoce contains 155,000 example sentences, all of which are part of the Longman Corpus Network, which has 300 million words. These example sentences are not made up at random, but are selected from various books, newspapers, magazines and people's oral and Internet expressions in real life, which will help the majority of English learners to fully understand the use of words in specific contexts and learn "fresh" English.

3. The phrases are well-matched, and the arrangement is clear at a glance. The 4th edition of LDOCE contains 220,000 collocation phrases, which are summarized and analyzed in detail for readers. In order to further facilitate the reference of the majority of English learners, ldoce has also created a special blue box to include these collocations.

The highlight of the fifth edition is the image of the iPhone version of the CD, not the printed version, and the printed version has become a supporting role, so it is obvious that the advantages of the fourth edition I hope it can help you to be satisfied and hope to adopt it.
