Gap-fill and vocabulary
Read the complete sentence, type the missing word, and re-enter it after checking the answer to confirm the meaning.
LANGBOX / ENGLISH READING PRACTICE
Read real content first, look up the words you need, then let spaced repetition bring them back as practice. Level-appropriate courses, sentence work, and grammar practice cover the rest.

Learning path
LangBox connects comprehension, lookup, and vocabulary review in one path. Use only the parts that fit the material and your available time.
Open a foreign-language webpage you can mostly follow, keep the original visible, and use the paragraph translation when needed.
Double-click an unfamiliar word for pronunciation, part of speech, and definitions, then return to the sentence to confirm the sense.
With Personalized learning recommendations enabled, eligible translations using LangBox managed models with remaining credits can enter the learning workflow.
Use cloze, spelling, synonym, and sentence activities to meet expressions again when they need more practice. FSRS schedules each review from how well you remembered the word last time.

The public practice pages are available without sign-in or installation. The extension adds a fuller review workflow that can connect practice with your reading history.

Practice is more than a completion count. Each set includes answers and explanations so you can separate correct spelling, suitable context, and reliable recall.
Read the complete sentence, type the missing word, and re-enter it after checking the answer to confirm the meaning.
Build a sentence word by word, or use was/were and other contrasts to check agreement, tense, and structure.
Open help when you need it. Independent answers and completions after viewing an answer are distinguished for later review.
READING PRACTICE FAQ
Review the course scope, practice formats, and the extension workflow before choosing where to start.
Any real page you read with the extension: an article, documentation, a PDF or an EPUB, with the translation under each paragraph and the dictionary a double-click away. There is no graded reader library; the practice is the material you already want to read.
The review part is. Words and expressions that enter the learning workflow come back through cloze, spelling, synonym and sentence activities, and FSRS sets the next review date from your answers. It is built around what you read rather than imported decks.
LangBox currently offers two public practice sets: CEFR A2 English grammar and IELTS grammar and expression. Both open directly without sign-in or installation.
The A2 set covers past forms, future plans, comparatives, and common quantifiers through 20 gap-fill questions plus sentence and grammar activities.
The IELTS set practises concession, inversion, conditionals, and common ways to express opinions and trends in academic and workplace contexts. It is study practice, not an official test or mock exam.
Yes. Every question includes a reference answer and explanation. Independent answers and completions after revealing an answer are counted separately so you can see what needs more review.
When Personalized learning recommendations are enabled, eligible translations can enter the learning workflow and return through cloze, spelling, synonym, and sentence activities. Whether material is generated depends on the model and available credits.
The public A2 and IELTS practice pages work without sign-in or installation. The extension connects bilingual webpage reading and dictionary lookup with personalized review.
