Since the mid-1990s,many Chinese farmers have had amazing rice harvests. For many years, Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind, called super rice. Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice. Today farmers can grow almost one and a half times more rice than they could grow in the past.
Doctors might be able to use vegetables to fight cancer now. US scientists have discovered a way to put a chemical into tomato plants while they are growing. When cancer patients eat the tomatoes, the tomatoes will fight the cancer in their bodies. These cancer-fighting vegetables are not yet for sale, because scientists have not finished testing them. If the study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.

Most people may think that people who write computer code (代码) must be good at Maths and logical (逻辑的) thinking. However, people who write computer code say that creativity is also important for writting code.
Software developers (开发者) in the USA have created a game called Osmo Coding Jam. The game is designed to help children use the creative side of their minds when learning to code. Children can play the game on iPads.
Tanya Dodge is the mother of two children who play the game. According to her, these activities give her children important skills for the future. “It’s an analytical (分析的) skill,” said Dodge.
But the developers believe writing code is not just an analytical skill. “We want to explore the creative side of coding that I think is often not as explored,” said Felix Hu, an Osmo engineer. Hu added, “The coolest part is that we’re teaching kids how to be creative with code and that’s a really important thing that kids should get comfortable with because coding is creative.”
Hu also sees many parents who feel that software code is a second language that children need to learn to succeed in future jobs. Tanya Dodge agrees. She said, “l think you’re going to have to understand the idea of coding will work well in the future.” Hu also explains that very often kids grow up not understanding how a computer works. He says by breaking it down to a lower level, kids can understand that the computer isn’t as smart as they think it is.
1.What is Osmo Coding Jam designed for?
A.Training kids’ logical thinking. B.Helping kids learn to code fast.
C.Helping children learn Maths well. D.Helping kids become more creative.
2.What does Tanya Dodge think of Osmo Coding Jam?
A.It needs to be improved. B.It can help kids play well.
C.It is of great help to today’s kids. D.It is not perfect in training kids’ analytical skills.
3.What can we learn from the passage?
A.If someone doesn’t learn Maths well, he or she can’t write code.
B.Creativity comes from writing code in daily life.
C.Writing code is just a skill which helps kids to analyze things well.
D.A lot of parents agree that software code will be useful for their kids’ future jobs.
4.The writer wrote this passage __________.
A.to tell how to learn to code well B.to tell about a new game for kids
C.to encourage kids to learn to study well D.to show the importance of creativity

One of the problems with passwords is that users forget them. In order to remember them, people use simple things like their dog’s name, their birth date, or the name of the current month-anything that will give them a clue to remember what their password is.
For the curious hacker (黑客) who has gained access to your online account, this is the same as locking your door and leaving the key under the doormat (门垫).
To create a safe password that is easy to remember, follow these simple steps:
● You should never use personal information as part of your password. It is very easy for someone to guess things like your last name, pet’s name, child’s birth date and other similar details.
● There are tools available to help attackers guess your password. With today’s computing power, it doesn’t take long to try every word in the dictionary and find your password, so it is best if you do not use real words for your password.
● You can make a password much safer by mixing different types of characters. Use some uppercase letters (大写字母) along with lowercase letters (小写字母), numbers and even special characters such as “&” or “%”.
● Rather than trying to remember a password that is created using various character types and is not a word from the dictionary, you can use a “passphrase”. Think of a sentence or a line from a song or poem that you like and create a password using the first letter from each word.
For example, rather than just having a password like “yr $ 1 Hes”, you could take a sentence such as “I like to read the About. Com Internet network security website” and convert it to a password like “il2rtA! nsws” by using the number “2” for the word “to” and using an exclamation point (感叹号) in place of the “I” for “Internet”. You can use a variety of character types and create a safe password that is hard to figure out, but much easier for you to remember.
● You should use a different username and password for each login you’re trying to protect. That way, if someone figures out one of your passwords, the others are still safe. Another approach, which is less safe, but provides a fair balance between security and convenience, is to use one username and password for sites and applications that don’t need the extra security, but use unique usernames and more safe passwords on sites that require more security, such as your bank’s website.
1.How is a password made up of one’s dog’s name or birthdate?
A. It is safe and easy to remember.
B. It can get hacked easily by attackers.
C. It suits those who have a poor memory.
D. It is the most commonly used type of password.
2.According to the article, what is a passphrase made up of?
A. Different character types.
B. A long dictionary word.
C. The title of a song or a poem.
D. The first letter from each word of a sentence.
3.Which of these passwords might be the safest according to the article?
A. jessica208. B. yr $ 1 Hes.
C. HERO&37. D. il2rtA!nsws.
4.What’s the article mainly about?
A. How to make your passwords safer.
B. How hackers get access to computers.
C. How to protect your private information online.
D. Typical problems with passwords.

I think it is safe to say that snakes are not popular among most people. It would be hard to find a person who is neutral (中立的), or simply doesn’t care one way or the other. What I wonder is why something even without legs causes such great fear.
Snakes are quite useful, but that doesn’t seem to matter. Snakes help control the population of mice. Without snakes, perhaps we would find mice everywhere. Most of us, however, would rather see a mouse than a snake.
The poison argument (毒性的争论) is a strong one. Some snakes are poisonous, and this causes people’s death. However, the poisonous snakes are only a small number. We can’t say all the snakes are bad just because of a few dangerous ones.
And what do we do with the people who really like snakes? They like snakes even more strongly than we dislike them. These people learn about them, find them out, and watch them carefully. Why? The only reason I can think of is that these people are open-minded. They are able to put aside differences and welcome the snake as a friend.
Whatever the reason for our like or dislike, snakes do something good in the circle of life. They would prefer to be left alone, and that is what we should do. If you’re lucky, you might not run across more than a few of them in a lifetime. That would be fine with most of us.
1.How does the writer describe the appearance of snakes?
A. Something even without legs.
B. Something not popular among people.
C. A person who is neutral.

A. They welcome snakes as their best friends.
B. They would rather see a mouse than a snake.
C. They wonder why snakes can cause great fear.
D. They learn about snakes and watch them carefully.
3.Although some snakes are poisonous, ______.
A. they cause many people’s death
B. they control the population of mice
C. they are not dangerous to people
D. they are only a small number
4.People who really like snakes are open-minded because they ______.
A. are able to put aside differences
B. think all the snakes are poisonous
C. are able to deal with poisonous snakes
D. take part in the poison argument
5.The last paragraph seems to tell us that the writer ______.
