What comes to mind when you hear the phrase “space meat”? It sounds quite weird. But in fact it could be the future of the human diet.

A Russian astronaut recently “grew” meat aboard the International Space Station. Yes, you read that right—he grew it using cells (细胞) provided by an Israeli company called Aleph Farms. But in fact, he was not the first person to create lab-grown (实验室培育的) meat. Dutch scientist Mark Post grew the first lab meat in 2013.

But why bother growing meat in a lab when we can get the real thing from cows? For one thing, lab-grown meat is healthier. “We gain greater control over what the meat consist of such as its fat content (脂肪含量).” Mark Post said in an interview. Lab-grown meat is also free of the chemicals that are used on farms, such as pesticides (农药) and growth hormones (激素).

Are there other ways to replace regular meat? McDonald is trying to do so with the P.L.T., which stands for plant, lettuce (生菜) and tomato. The first P.L.T burgers are already being sold in Canada according to the fast food company.

The “meat” in the P.L.T. is made out of Beyond Meata plant-based meat substitute (替代品) created by a company from Los Angels, US. The company uses pea, rice and bean proteins (蛋白质) to produce patties (肉饼) that look and taste like real meat.

Experts doubt whether these products are healthier than real meat. But plant-based meat has already proven to be a success with several fast food companies already offering such products on their menus, according to Fox Business.

Fu Lei’s Family Letters is a book of letters written by Chinese translator and writer Fu Lei to his elder son Fu Cong. Between 1954 and 1966 Fu Cong spent a lot of time away from home to train as a piano player. As     36     result, writing letters became Fu Lei’s usual way of communicating with his elder son. Fu Min, Fu Lei’s younger son, edited the letters and the book     37     (publish) in 1981.

The book is a full display of Fu Lei’s family tradition and value. To Fu Lei, education is not only a family matter,     38     also something with great social value. The purpose of education of a person, as shown in Fu Lei’s Family Letters, is     39     (make) that person useful to society. In one of his letter, Fu Lei praised his son Fu Cong after winning a piano competition. Fu Lei wrote, “We are happy because you make your country proud. We are even     40     (happy) because you bring joy to people through music!”

In his family letters, Fu Lei also advised his son     41     (read) famous Chinese texts. When reading these books, he told Fu Cong to     42     (complete) understand their meanings and connect ideas with feelings, for that would help him become a better person. To Fu Lei,     43     (learn) to be a good person comes before any academic training.     44     27 December 1954, Fu Lei wrote “Everyone should be a good person before becoming an expert in any area. Otherwise, that person will not achieve much, no matter     45     knowledgeable he or she is.”
