Smart Home Lights
Many people are changing the way they light their homes today. Instead of using normal lights, they are buying smart home lights. You can easily control these new lights with your mobile (19)…………… . It is very simple to use the app to turn the lights (20)…………… when you walk into your house.
These special lights are also fun because you can change their (21)…………… . For example, you can choose a warm yellow for reading a book or a bright blue for a party. You can put them in any (22)…………… in your house, like your bedroom or the kitchen.
Some smart lights are very clever. When it gets (23)…………… outside, they know it is evening and turn on for you. This means you never have to come back to a house with no light. Using smart lights is a great (24)…………… to make your home more modern.
19 A phone B screen C camera
20 A up B on C over
21 A sizes B shapes C colours
22 A room B building C floor
23 A dark B late C grey
24 A way B road C path
Answer Key & Explanations
19 A (phone): "Mobile phone" is the standard English collocation for the device you use to control apps. A "screen" and a "camera" are just parts of a device, not the whole thing used to run a smart home app.
20 B (on): "Turn on" is the correct phrase-level verb meaning to make a machine or light start working. You "turn up" music to make it louder, and "turn over" means to flip something.
21 C (colours): The broader context in the next sentence mentions "yellow" and "blue", which are colours. You cannot change the "sizes" or "shapes" of the light coming from a bulb in this context.
22 A (room): A "room" is a specific space inside a house, which perfectly fits the semantic context of "bedroom" and "kitchen". A "building" is the whole house, and a "floor" is just the surface you walk on.
23 A (dark): "Get dark" is the correct semantic fit to describe the sky losing sunlight in the evening. The time can get "late," but you do not say it gets late "outside." "Grey" usually describes cloudy weather, not the evening sky.
24 A (way): "A great way to [do something]" is a highly frequent English collocation meaning a good method or idea. "Road" and "path" are physical routes for walking or driving and do not fit this abstract expression.

Robot Vacuum Cleaners
Many families today are busy, so they do not have a lot of time to tidy their homes. Because of this, they are buying a special kind of robot to do the (19)…………… for them.
A robot vacuum cleaner is a small round machine that travels across the (20)…………… . It has little (21)…………… under it, so it can turn easily and go under beds or sofas.
You do not need to push this clever machine. It is very good at (22)…………… around the house by itself. You can even turn it on when you go out to school. It will happily wash the carpets when it is completely (23)…………… in the room.
It is a fantastic (24)…………… to keep your bedroom tidy without doing any hard work!
19 A cleaning B washing C fixing
20 A floor B wall C roof
21 A wheels B legs C shoes
22 A moving B walking C climbing
23 A alone B empty C single
24 A way B course C road
Answer Key & Explanations
19 A (cleaning): The correct English collocation for tidying a house is to "do the cleaning." The phrase "do the washing" usually refers specifically to cleaning dirty clothes, and "fixing" means repairing something that is broken.
20 A (floor): A vacuum cleaner travels on the flat surface at the bottom of a room, which is the "floor." It cannot travel up a vertical "wall" or upside down on a "roof."
21 A (wheels): Machines and vehicles roll on round objects called "wheels." Humans and animals stand on "legs" and wear "shoes," but a small robot does not have these body parts.
22 A (moving): The machine travels from place to place, which is "moving." Because it uses wheels, it is not "walking" (which requires legs), and it cannot go up stairs, so it is not "climbing."
23 A (alone): The previous sentence talks about you going out to school. This means the robot is the only thing left in the house, so it is "alone." A room can be described as "empty," but the robot itself is not empty. The adjective "single" just means one in number.
24 A (way): This tests the phrase-level expression "it is a fantastic way to," which means a great method or option for doing something. While a "course" and a "road" are physical paths you can travel on, they do not form this fixed English expression.

Video Calling Family
Many teenagers have family members who live in another city or country. In the past, people only used telephones to speak to them, but today it is much easier. You can use a smartphone or tablet to make a video call and look at their faces on your (19)…………… .
To do this, you just need a fast connection to the (20)…………… . You also need to turn on your device's (21)…………… so the other person can see you. It is amazing because you can watch your young cousins growing up, even if they live far away.
When you are (22)…………… to your grandparents online, you can show them your new pets or your bedroom. Video calling is a fantastic (23)…………… to stay close to the people you love. It helps everyone to (24)…………… time together and feel happy.
19 A screen B television C photo
20 A internet B website C program
21 A camera B radio C clock
22 A talking B saying C telling
23 A way B road C path
24 A spend B make C keep
Answer Key & Explanations
19 A (screen): Semantic fit. A "screen" is the flat glass part of a phone or tablet where you see digital images. A "television" is a different, much larger machine in a living room, and a "photo" is a single still image, not live video.
20 A (internet): Broader context. To make a digital video call across cities, your device must have a connection to the "internet". You do not connect to a single "website" or "program" to get the network access needed for this to work.
21 A (camera): Semantic fit. A "camera" is the specific tool on a device that captures video so "the other person can see you". A "radio" is only for listening to audio, and a "clock" is for telling the time.
22 A (talking): Phrase-level meaning. The verb "talking" is the only option that pairs correctly with the preposition "to" (talking to your grandparents). "Saying" requires a specific word as an object (saying hello), and "telling" requires a direct personal object without "to" (telling your grandparents).
23 A (way): Collocation. "A fantastic way to [do something]" is a fixed phrase meaning a great method or option. "Road" and "path" refer to physical surfaces you walk or drive on, and do not fit this abstract meaning.
24 A (spend): Collocation. The verb "spend" strongly collocates with "time" (spend time together) when talking about doing an activity with someone. In English, we do not "make time together" in this context, and we use "keep time" for music or clocks.
