Sarah had always wanted a pet, and three years ago, she adopted a small cat named Whisker.

Since then, Whisker has become her closest companion.

Every afternoon, she rushes home, and he waits by the window.

Yesterday, when she arrived, Whisker wasn't there.

She had been calling his name and shaking his treats for almost an hour when her parents walked in.

Right now, Sarah is still searching.

"I will check outside again," she says to herself.

By the time she finds him, she will have spent the entire evening looking.

Emma and Jake have always loved science.

This year, they decided to enter the school's science fair, which took place yesterday.

For weeks, they had been testing how different types of soil affect plant growth.

By the time the fair started, their project was fully prepared.

They explained their results to the judges while students were walking around, looking at other displays.

Today, they are still talking about their success.

"We will win next year, too," Emma says confidently.

By the time the assembly takes place next week, they will have received their first-place award and shared their project with the whole school.

Last night, when they got home, their parents were beaming with pride.

Right now, Jake plans their next project.

He says, "We will be even better prepared next time!"

The sun shines brightly every morning, but today it is raining cats and dogs.

Yesterday, it rained all day long.

Since I moved here, I have seen many different weather patterns.

Tomorrow, the sun will shine again, and at this time tomorrow I will be enjoying a picnic in the park.

Nowadays, some desserts are very popular and well-known worldwide.

Today, we will learn about where and when those desserts might have originated.

First, scones are said to have come from Scotland in the early 1500s.

Some historians assume that it was named after the Stone of Scone, on which he king of Scotland sat while being crowned.

Secondly, it is generally agreed that gelato was invented in Italy in the 16th century.

Historians aren't sure who invented it, but a lot of people believe that an Italian architect, Bernardo Buontalenti, created a form of the modern-day gelato.

Thirdly, the first marshmallows are said to have been produced in Egypt around 2000 BC.

Marshmallows were offered only to the ancient Egyptian gods and pharaohs as a candy or dessert.

All of these desserts have been loving for centuries all over the world.
