In the morning, I am woken up by natural sunlight as curtains are drawn automatically at scheduled time. When I walk into the livingroom, I find my breakfast has already been made and kept at the right temperature. As I am enjoying my coffee, I think about what to do next. The moment I decide to watch a movie, the TV is turned on and the lights are dimmed. After two hours, I plan to make lunch. To my surprise, when I enter the kitchen, all the dishes on my mind are already being cooked! So I sit around and wait for half an hour. The lunch is very delicious, and even before I know it, all the dishes are done.
My day with smart home devices
With nothing else to do, I pick a book and start reading. As my eyes move to the end of the last line, the page is turned automatically. Before long, I start to feel sleepy. Before I fall fast asleep, I am tucked in by my bed. In my dream, I am looking for things to do very hard as everything is done automatically the moment I think of it. Just as I am getting worried, mom’s voice rings in my ear, “Wake up Geroge! Wake up! Today is your turn to do the household chores!” Dragging myself out of bed, I feel strangely relieved, “After all, I finally have something to do!”

Dune is a science fiction novel by Frank Herbert. It won the Nebula Award in 1965 and shared the Hugo Award in 1966. People generally consider it one of the best sci-fi novels ever. As the novel opens, each planet is ruled by a Great House. An emperor has control of a planet called Arrakis, where ”spice” can be tapped. Every planet wanted this spice because it gives people amazing abilities. As the emperor fears that Leto, the ruler of the Atreides House, will challenge him, he plots a war between Atreides and another house…
Read the passage below and see if you can improve its
coherence by rewriting sentences using passive voice
It is generally considered
This “spice” is wanted by every planet
he will be challenged
by Leto, the ruler of Atreides House
EXAMPLE
Many animals and plants are endangered due to loss of habitat. To solve the problem, some measures must be taken to protect them. Cutting down trees without permission should not be allowed. Forests should be well looked after…
List some environmental problems and their causes. Then write solutions to each problem.
Possible answer
Air pollution is a big problem, due to coal power plants and car emissions. To solve this problem, the building of coal power plants should be severely limited and those that already exist should be equipped with devices which clean the smoke they produce. Cars should also have very high emissions standards and should be kept from being driven in large cities when the pollution is bad.
List some environmental problems and their causes. Then write solutions to each problem.
Possible answer
A lack of green spaces in large cities is a problem due to overbuilding and overuse of concrete. To solve this problem, new construction should be limited, and when a company wants to build a new building it should be forced to include some green spaces in their designs. When roads are constructed or repaired, a grass strip should be included in the design, and trees should be planted on either side of the road. Finally, a survey could be made of unused property in the city, and some of this property could be purchased and made in to public parks.
