Man has been interested in robots for quite some time. Scientists are always inventing new and good robots, which will play an important role in our future lives.
They will take over jobs such as preparing meals, washing dishes, and sweeping the floor, so that we will have more free time to have fun.
They will do all the heave and dangerous work, and be put in hospitals, schools and offices.
Whenever we feel sad, lonely or upset, we can have a chat with a robot. Robots will not only be good friends but they will also offer us good advice.
In conclusion, robots will be more and more intelligent and will benefit us in many ways.
A. Robots will be our friends.
B. Robots will help us with our work.
C. Robots will be of help in doing housework.
D. Robots will replace humans in many ways.
3 . The United Arab Emirates (UAE) is mostly a desert. However, this has not stopped the country from creating great building projects. On September 26, UAE officials announced another ambitious project — Mars Science City. Expansive deserts and miles of coastline provide plenty of options for safe rocket launches (发射). And its position on the Earth makes it especially appealing as the spin of the Earth provides an extra push, meaning less fuel is needed to get payloads into orbit. All these seem to make it possible.
The Mars City Project, designed by Bjarke Ingels Group, or BIG, will provide a realistic model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE’s Mars 2117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed bin Rashid, Prime Minister and ruler of Dubai, says, “The UAE seeks international support to develop technologies that benefit humans, and lay the foundation of a better future for more generations to come.”
Built outside Dubai, the 1.9 million square feet city is expected to cost $135 million. It will consist of several dome-shaped laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the word will be invited to conduct research to come up with methods to create food, water and energy, using techniques which can be copied onto the red planet. The living spaces, where the researchers can live for up to a year, will simulate the planet’s conditions as much as possible.
The research city will also include a museum featuring famous space achievements to help educate and inspire children to undertake space exploration and discovery. To discover whether the construction method works on Mars, the museum’s walls will be 3D printed using the sand from the nearby desert. Now, if they would only add some living quarters for the general public to experience life on Mars without leaving Earth, life would be perfect.
