Before the school concert, a message on the noticeboard says: "Please recheck the poster before printing it."

Why should a neighborhood repair fair use clear labels? At the Riverside community center, volunteers prepare a table where visitors can exchange jars and cloth bags. A sign currently says, “Bring items you can use again. Choose containers that do not break easily.” Maya wants to replace these sentences with a short label for visitors who are still learning English. On other signs, she notices re- in rebuild, un- in unsafe, and -able in washable. She knows that the new label must describe the containers, rather than give visitors an order, and must express both repeated use and possibility.

Analyze the word parts mentioned in the text. Identify the label that describes containers that can be used again.

“A bottle should have more than one life,” said Maya, who helps at a water-refill station in a city park. Visitors can borrow steel bottles and bring them back after a walk. The station staff uses short signs to guide people. One sign says that a reusable bottle can be used again. Another says that a washable bottle can be cleaned with water. For a new group of bottles, the staff needs a word to describe bottles that people can fill with water again. Maya wants the new sign to follow the same word-building pattern used in the other signs.

Analyze the word-building pattern in the signs and identify the meaning of the suffix in “refillable.”

Why throw away a cup after a single drink? At the Green Streets Festival, food stalls will serve juices in hard-plastic cups. A notice near the entrance asks visitors to choose a reusable cup, pay a small deposit, and return it to a collection point after drinking. Volunteers will wash the returned cups and send them back to the stalls during the same day. Paper cups will still be available, but they will be placed in waste bins after use. The organizers expect the return system to reduce the number of cups sent to landfill.

Analyze the word “reusable” in the notice. What does the combination of its prefix and suffix indicate about the cups?

While walking through a weekend charity market, I stopped at a table full of personal care products. A volunteer checked each item before putting it on sale. She held up a box of toothpaste and pointed to the thin plastic seal around it.

“We can only sell items with the seal still on,” she said. “People need to know no one has used them.”

On the table, one sign read: “Unopened products — safe to donate.” Another sign invited shoppers to bring “reusable bags” to reduce waste. I bought two soaps that still had their seals and put them in my backpack.

Based on the text, identify what the prefix in the word “unopened” indicates about the products.

Have you ever noticed how some English words start with the same letters but have different meanings? A student collected these examples from newspapers and blogs:

• preview: She watched the preview of the new series before the release.
• preheat: Always preheat the oven to 180°C for baking cakes.
• prehistoric: Fossils reveal life in prehistoric times millions of years ago.
• prepay: Many commuters prepay their tickets online to save time.

All these words share the prefix pre-. By comparing their uses, you can infer what this prefix adds to a base word.

Com base no texto-base, identifique o significado do prefixo pre- na formação das palavras apresentadas.

A linguistics blog post discusses how English words often change meaning when certain prefixes are added. The author gives examples:
– un + fair = unfair (not fair)
– dis + allow = disallow (not allow)
– re + view = review (see again)
– mis + spell = misspell (spell incorrectly)
From these examples, readers can identify patterns in forming new words with prefixes.

Com base nos padrões apresentados, qual palavra formada com o prefixo adequado significa “o contrário de appear” (aparecer)?

A small design studio introduced reusable sketchbooks, allowing artists to erase and redraw their ideas. The notice on the wall read “Please return used pages for reuse.” In the same notice, employees saw terms like unpredictable weather warnings and maintenance-free equipment. Observing these words, students noticed that adding certain letter groups at the beginning or end of base words changes their meanings.

Analise the prefix in reusable and, by analogy, determine which word correctly uses the same prefix with the root cycle to mean “use again.” Which word is it?
