Sure! Here's a step-by-step explanation of how to complete the text using the given words: promise, protect, keep, listen, has, make.

1. First, let's carefully read the text to understand what it is about.

2. Look for any missing words or gaps in the text where we need to fill in the blanks using the given words.

3. Let's start by reading the text and identifying the missing words:

"My mom always ________ me that she will ________ me safe. She says that she will ________ me and ________ to me whenever I need her. She ________ always ________ her promises."

4. Now, let's use our understanding of the meanings of the words given to complete the text.

- "My mom always (tells) me that she will (keep) me safe. She says that she will (protect) me and (listen) to me whenever I need her. She (has) always (kept) her promises."

5. Let's explain the choices made for each blank:

- "My mom always (tells) me that she will (keep) me safe." In this sentence, we use the word "tells" as it means she communicates this information to me. We use the word "keep" for the next blank because it fits the context of keeping someone safe and fulfilling the promise.

- "She says that she will (protect) me and (listen) to me whenever I need her." Here, we use the word "protect" because it means to keep me safe from harm. We use the word "listen" as it means to pay attention and understand what I'm saying.

- "She (has) always (kept) her promises." In this sentence, we use the word "has" to indicate that she has consistently done something. We use the word "kept" to show that she has fulfilled her promises in the past.

By using these words in the appropriate places, we have completed the text:

"My mom always tells me that she will keep me safe. She says that she will protect me and listen to me whenever I need her. She has always kept her promises."

This completed text shows that the speaker's mom assures them of her care and protection, and she has consistently fulfilled her promises.

I. Answer the following questions:

1. When was electric phenomena discovered?
The discovery of electric phenomena dates back to ancient times. However, the systematic study and understanding of electricity as a scientific phenomenon began in the 17th century. In 1600, the English scientist William Gilbert conducted experiments with electricity and coined the term "electric force."

2. What does a force of attraction mean?
A force of attraction refers to the pull between two objects or substances due to their electric charges. The electric force of attraction occurs between objects with opposite charges. For example, when you rub a balloon on your hair, it becomes negatively charged, and it can stick to a wall due to the force of attraction between the negatively charged balloon and the positively charged wall.

3. What kinds of electricity are there?
There are two main types of electricity: static electricity and current electricity.

- Static electricity: This type of electricity refers to the buildup of electric charges on an object. It occurs when there is an excess or deficit of electrons on the surface of an object. The charges do not flow and remain static until they are discharged. Examples of static electricity include the spark you see when you touch a metal object after walking on a carpet or the crackling sound when you take off a sweater.

- Current electricity: Current electricity is the constant flow of electrons in a circuit. It is the type of electricity we use in our homes and daily life. Current electricity requires a continuous path or circuit for the flow of electrons. Devices such as light bulbs and electrical appliances work using current electricity.

Both static electricity and current electricity play essential roles in our lives and have various applications in technology, medicine, and many other fields.
