1 . Reading is often seen as an individual activity, but it definitely doesn’t have to be. If you join a book club, reading with others can be a positive social interaction.
In such a fast-paced world, sometimes it’s challenging to find the time and motivation to read. By joining a book club, you make a commitment to read the book of the month or the week and discuss your insights with others.
Reading is one of the most important things you can do for your brain, but reading with other people can make it even better.
Another plus is that at a book club you get together with your club members regularly, with whom you can share not only your thoughts about books but also other aspects of life.
A.This can help you meet your reading goals. |
B.Joining a book club can offer you many benefits. |
C.Book clubs can boost your happiness and well-being. |
D.Do you often have difficulty finishing reading a book? |
E.This brings a sense of community, belonging, and friendship. |
F.Have you found yourself always reading similar types of books? |
G.Meeting with others and exchanging ideas about things is the key. |
2 . Four Inventions That Changed the World
The course of human evolution has been filled with inventions. The following inventions changed the world in one way or another.
Match
Many of us wonder what life was like before matches. We can thank a British pharmacist and his dirty mixing stick. In 1820s, John Walker noticed a dried lump on the end of a stick while he was stirring a mix of chemicals. When he tried to scrape (刮掉) it off, flames appeared. The initial matches were made of cardboard but soon the matches came in a box equipped with a piece of sandpaper for striking.
Penicillin
Penicillin was discovered in 1928 when a young bacteriologist, Alexander Fleming, was tidying up his lab. After having been on vacation, he returned to work to find that a dish of Staphylococcus bacteria had been left uncovered, and he noticed that mould (霉菌) on the culture had killed many of the bacteria. His further research found that it could kill other bacteria.
Microwave Oven
Of all the sci-fi kitchen appliances, the microwave oven really relieves the load on housewives. It was discovered in the 1940s. When Percy Spencer, an engineer, was working on a magnetron (磁控管), he noticed that a chocolate bar in his pocket had started to melt due to the microwaves. Spencer found that indeed, when food was placed in the box with the microwave energy, it cooked quickly.
Plastic
The first plastic was invented in 1907 by Leo Hendrik Baekeland. His initial quest was to invent a ready replacement for shellac (虫胶), an expensive product got from lac beetles. Baekeland combined formaldehyde (甲醛) with a waste product of coal, and heated the mixture. Rather than a shellac-like material, he created a substance that didn’t melt under heat and stress.

10 . The 2023 Nobel Prize in Physiology or Medicine has been awarded to Katalin Karikó and Drew Weissman for their work on mRNA vaccines (疫苗), a crucial tool in holding back the spread of COVID-19.
Karikó,68, is from Hungary. In the 1970s, she began studying a new area of research: messenger RNA (mRNA). mRNA is a special molecule (分子) which carries instructions that tell cells what proteins to make. Proteins are one of the building blocks of life. They’re involved in almost every process in living things, from fighting diseases to building muscles to helping our bodies work. Karikó was excited about the idea that mRNA could be used to help the body fight many different diseases.
In 1985, Karikó moved to America to continue her research. In 1989, she joined the University of Pennsylvania (UPenn) in Philadelphia as a scientist. But as time went on, the initial excitement surrounding mRNA research started to disappear, and other scientists thought it was too financially risky to fund. Karikó had trouble getting money for her research. She even got a pay cut from the school. What’s worse, at this time, she suffered from cancer. But she stuck at it.
Karikó got to know another UPenn scientist, Drew Weissman in the late 1990s while photocopying research papers. He was hoping to find a way to create a vaccine for a disease known as HIV. The two began talking and soon decided to work together.
One of the biggest problems in using mRNA as a medicine was that the human body saw mRNA as an enemy and fought it off. Together, they came up with an approach to treating mRNA.In 2005, they published their key discovery: mRNA could be changed and delivered effectively into the body to activate (激活) the body’s protective immune system. Thanks to their work, companies were able to develop mRNA vaccines far more quickly than ever before, which have saved millions of lives around the world.

A.Their idea on how to recognize COVID-19 fast. |
B.Their method of testing the mRNA vaccines’ effect. |
C.Their way to make the human body accept mRNA. |
D.Their experiment of activating the immune system. |
A.We should pursue excellence in our careers. |
