As the Chinese saying goes, a seed can change the world; a variety can benefit a nation.
Zhang Daorong, who has spent the last 26 years 1 13 new varieties of wheat and contributing to national food security, has done both. The 50-year-old, who is called the "mother of wheat", is a 2 at the Xiangyang Academy of Agricultural Sciences in Xiangyang city.
The research into new varieties requires strict standards and 3 experiments. "The first 4 is to find suitable parental types for a specific cultivation(培育) purpose. Then we try a hybrid(杂交的) combination," Zhang explained, "After several generations of 5 and selection, and when characteristics remain stable, we 6 a two-year process of yield testing and disease identification." And after several more founds of tests, a(n) 7 for evaluation and approval can be made for market production.
"Generally speaking, a good new 8 should produce high yields(产量), have stable production, and 9 good resistance to bad conditions," she added. "10 , it also should be accepted by the market."

If you use "123456", "password'' or "qwerty" as a password, you're probably aware that you're at the risk of being attacked by hackers(黑客). But you're not alone. Recently, password management service NordPass has carried out a study to determine the 200 most commonly used passwords around the world. They analyzed the data across 50 countries.
The findings show password choices are often attached to cultural references. . In the UK, "liverpool" was the third most popular password, with 224,160 hits, while the name of Chilean football club "colocolo" was used by 15,748 people in Chile, making it the fifth most common choice.
Women tend to use more positive and affectionate(深情的) words and phrases such as "sunshine" or "I love you", while men often use sports-related passwords. In some countries, men use more swear words than women.
Choosing long and complex passwords remains the main authentication mechanism (身份验证机制) for computers and network-based products and services. But we know people continue to choose weak passwords and often don't manage them securely. .
To overcome the security issues linked with password-based authentication systems, researchers and developers are now concentrating on creating authentication systems which don't depend on passwords at all. For example, two-factor authentication (2FA) and multi-factor authentication (MFA) methods are good ways to secure your accounts. These methods combine a password with biometric information (for example, a face scan or fingerprint) or something distinguishable, like a captcha(验证码). All in all, a secure password is the first line of defense against Internet attacks. Don't give up security for convenience.
A. As a result, they put themselves under potential online security threats.
B. The findings show that passwords tell our emotions and our identity.
C. Besides, there are other ways to protect your personal information.D. These are among the most popular passwords around the world.
E. The report also reflected different preferences between genders.F. People in some countries take inspiration from a football team.
G. They need the support of computer experts. -

When you are online, you can be anyone or anything. You can create your own image and a new personality. These digital identities are known as avatars(化身).
The first simple 2D avatars appeared in role-playing computer games in the 1980s. Yet, very few people knew that future avatars would have such a wide variety of forms and uses. By the late 1990s, they had been used in web chats.
When people started creating their own avatars, they discovered that they were going to have the power to create new identities that did not look or act like their real selves at all. They could dress their avatars in fancy clothes, or they could try being someone of the opposite sex. When Internet users realized that their avatars would be seen by many people, not just their friends, they started having more than one avatar. Avatars let you express yourself and they give you lots of room for creativity.
Of course, the avatar you choose says a lot about your personality. If your blog avatar is a picture of a cute cat, your message is "like relaxing and having fun". Well-known cartoon characters or laughing monkeys say "I'm a really funny person". Most people create avatars that have similar features to their personalities and that look more or less like them and act like them. However, people obviously make their avatars look better than they do in real life.
Nowadays, avatars are everywhere and very useful. In most web chats, people choose an avatar from a selection of ready-made images or create their own images. You can also use avatars that move around and talk when you type in your message.
Despite the advantages of avatars, the use of avatars has also caused a few concerns. Some users worry that they are spending so much time in virtual worlds that they are becoming afraid of meeting people in the real world. The use of several avatars can also be a risk, as people can use avatars to cheat others online.
