2 . Technology is likely to play a big part in reaching its climate goals in the future.

Fusion is the process that fires the sun. But some experts say it could someday power our homes. Fusion happens when the nuclei (核) of two atoms are subjected to extreme heat. This leads to the formation of a new larger atom and large amounts of energy. One problem is the process itself requires a large amount of energy. Developers of the technology haven’t yet performed a fusion reaction that releases more energy than it requires. In addition, running an electric power plant of fusion would require the resulting heat to be contained in an economical way.

Advanced nuclear plants would be smaller than today’s massive nuclear reactors. Experts say they could be used in rural areas and could take over for wind and solar power when the sun goes down or the wind dies. But advanced nuclear reactors are difficult and costly to build. Critics say they would also create more waste. And they would run on uranium (铀), which could make some advanced reactors more appealing to militants (激进分子) seeking materials to make weapons.

Currently, there are 15 direct air capture plants operating worldwide, getting CO directly from the air and puts the gas underground. The costs are currently high. But supporters say those costs will fall as the technology improves. They also say tax breaks for businesses could help the technology. But critics say offering large credits could actually lead to more plants continuing to burn fossil fuels.

Hydrogen (氢) can be mixed with natural gas to make a cleaner-burning fuel. This could power a fuel cell vehicle. Such a vehicle would release environmentally friendly water vapors.

So-called clean hydrogen can be produced using energy methods such as wind and solar. But those methods are more costly than “grey hydrogen”, which is made with fossil fuels. Geothermal power plants capture heat up to 370 degrees Celsius far below the earth’s surface. The heat creates steam that can turn turbines (涡轮机) to produce electricity. But the technology would need to greatly expand to become a major alternative to fossil fuels.

Robert was a carpenter (木匠). He was living in a village. His mother died a long time ago. His aged father, Kuppan, lived with Robert. Kuppan was very weak. He could not even walk well. He was so weak because Robert did not give him enough food.

Robert had a son. His name was Michael. Michael was just ten years old. He was a very good boy. He loved his grandfather. He had great respect for his grandfather. We did not like his father’s attitude and character to his grandfather, because his father was treating his grandfather cruelly. One day Kuppan was eating his food in the small plate that his son had given to him. The plate fell and broke into pieces. The food also fell on the floor. Robert was working at the other end of the room. He saw the broken plate. He was very angry with his father and used very sharp words to blame his father. The old man felt bad about what happened. He was sorry for his mistake. Robert’s words wounded him very deeply.

Michael saw this. But he was afraid to speak against his father. He was sad about his grandfather. But he was not powerful to stand in support of his grandfather. Then he got an idea.

The next day, Michael took some of his father’s tools and a piece of wood.

The carpenter was pretty shocked to hear that.

5 . Can we “design” a baby like we design a handbag? It may sound crazy, but a “designer baby” could be possible now. Of course, at the same time, there are both agreements and disagreements with it.

The “designer baby” idea comes from the research that allows scientists to make changes to human DNA and genes. Usually, it is done when the baby is still just an embryo (胚胎). By doing that, scientists hope that “designer babies” will less possibly be born with some certain serious illnesses.

During the 21st century, the idea became so popular that the research developed very quickly. Now, it has been firstly used to help born babies with their illnesses. One example of this is that Dr. Adrian Thrasher of University College London was able to save a 1-year-old child from leukemia (白血病) with the help of it. People learned that it was not only illnesses they could change, but also a baby’s gender and looks. A well-known event happened in 1996. An American couple, Monique and Scott Collins, decided to use this research to help them choose the gender of their next baby. They wanted to have a baby girl for they have had three sons. Moreover, people could also decide babies’ eye color, hair color and even things like height or how sportive babies will be.

Some people argue that it is not ethical (道德的) to design babies like designing a bag. It is strongly against the nature’s rules. Besides, it may not have any bad influence on the baby now, yet no one knows what will happen to him and his children after many years.
