What is the difference between a paper dictionary, an electronic dictionary and an electronic paper book?

The main difference is the size of vocabulary and the detail of usage;

Suggestion:

1, paper books (primary+intermediate) are used at the same time; Dictionaries are not expensive, so I suggest buying them all.

For non-English majors, it is recommended to look up the elementary level, not the words, but to learn the sense of language and recite the words. Start from the primary level, wait until the vocabulary reaches 20 thousand, and then transfer to the intermediate level. As for whether it is necessary to transfer to a higher level, it depends on your own ability.

2.APP+ paper version+electronic dictionary+dictionary pen;

Usually, the dictionary is mainly used to look up words. If you look through a paper dictionary, it will make people collapse.

If you are a college student, you can bring your mobile phone and download the Oxford Advanced Dictionary APP or Longman Contemporary Dictionary App directly.

If middle school students can't bring mobile phones, they can buy Casio electronic dictionaries or Youdao electronic dictionaries (money is tight, you can buy second-hand ones at salted fish).

If you have money, you can also start with a dictionary pen, and the words will come out as soon as they are swept away, thus improving reading efficiency.

Students are not advised to buy the paper version of Oxford advanced search terms. The paper version is generally used by primary and secondary school teachers to browse. In fact, many post-90 s English teachers directly use genuine APP to search for words.
