Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code(二维码). “We spent an hour or two in class learning how to generate(使产生) the codes, and in the end everything gets easier,”said Guo.“When students finish the homework, they keep it on WeChat(微信). Then, each student makes his own QR code and gives it to me. So I can check their work everywhere using my computer or telephone. ”

The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans(扫描) his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.

Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.”said Tingting, a student of Guo’s.

“The paper is not easy to keep, but the code is easy to keep and share,”Guo said.“It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”

However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their work, which doesn’t take them too much time. Also for teachers, it allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.

1.Guo’s students think the new way is _____.

A. Important B. interesting C. strange D. boring

2.Some parents are worried, because they think their children will _____.

A. talk with their teacher face to face

B. find the QR codes too difficult to use

C. hate the new way of handing in homework

D. spend too much time on computers or phones

3.What’s the main idea of the passage?

A. Some parents are worried about their children.

B. Teachers don’t need to check homework any more.

C. Using QR codes makes checking homework easier.

D. Students don’t need to hand in homework any more.

From 2016, Children in Finland would not be taught cursive handwriting. Instead of learning this skill, schools would be given the choice to teach keyboard typing in its place. The change shows typing skills are now more related than handwriting, but experts say the move could do harm to a child’s brain development.

“Most people would agree that everyone should at least be able to pick up a pen or a pencil and write a message that others can read,”said Misty Adoniou, a lecturer.“But beyond legibility(易读性), does it matter how you form your letters when you handwrite?”

She continued there was research connecting fluent(流畅的) handwriting with better written articles,“but the key isn’t the quality, form or style of the handwriting, but rather the automaticity(自动性) of the handwriting.”

Reports have also found that by the age of eight, children can already type faster than they can handwrite. But, as Misty Adoniou agreed, handwriting can play an important part in brain development.“Research shows that learning to write in cursive further improves students’ motor and visual(视觉的) skills, eye-to-handco ordination, hand and finger skills, and brain development. The physical act of handwriting also helps the memory of information and the flow(流动)of ideas.”

For example, in a recent study, researchers did brain scans on five-year-olds before and after receiving different letter-learning tasks. In children who practiced writing letters by hand, the neural(神经的) activity was more improved and“aduit-like”than in those who had simply looked at letters. “Technology can encourage and support plenty of child development and educational objectives, such as physical and health、”explained Dr.Leves, “And there is a body of research supporting the idea that children learn best when they’re having fun.”

But as Ms Adoniou concluded:“With so many things to do in a school day, it is hard to see why handwriting lessons continue. No matter how standardized we try to make handwriting, we all end up with our own style. Perhaps we’d do just all well to let children find their own style.”

1.Ms Adoniou probably agrees that you will write articles better when _____.

A. you care less about your handwriting

B. you have a special style of handwriting

C. you improve the quality of handwriting

D. you have different forms of handwriting

2.According to Ms Adoniou, cursive handwriting _____.

A. improves children’s eyesight

B. makes children’s hands strong

C. makes children have fewer ideas

D. helps children’s brains develop better

3.What is the passage mainly about _____?

A. How to teach keyboard typing.

B. The reasons why students drop pens.

C. Some opinions on cursive handwriting.

D. How to improve your own writing style.

Next time you hear yourself wishing for something better in your life, remember the word “SMART”. When you’ve decided to take action, read the following first.

S is for specific (具体的): For example, instead of setting a goal (目标): of “I want to lose weight”, set yourself a specific goal like “I want to lose five kilograms”. If you want to climb a high mountain, start your research, set a date and train for the climbing fitness.

M is for measurable (可测量的): Don’t try to “become healthy”, instead, set a goal that can be measured while carrying out an improved eating, exercise or lifestyle plan. For example, try to go to the gym for an hour three times a week, to visit your grandma once a week for an evening meal, or to eat no more than 200 grams of chocolate a week.

A is for achievable(可完成的): If you’ve never exercised in your life, don’t try to take part in the 2020 Olympics. Rather, get walking with a specific goal of how many steps to take a day. No need to try for the stars—baby steps are good.

R is for relevant (恰当的): Many of us choose goals that seem right, but are in fact wrong. They may go on for a few weeks before they fail. Try to avoid making the same mistake—rather choose goals that really speak to you.

T is for time-conscious (心中有数的): Finally, be very clear in your mind about how much time you are giving yourself to achieve the goal. That way, you know when you’ve succeeded, failed or whether you need to work harder to finish it before the last day.

1.According to the passage, the writer tells us how to_______.

A. lose weight B. take exercise

C. set a goal D. spend time.

2.What does the word “SMART” mean in the passage?

A. Five exercise plans. B. Five suggestions.

C. Five training steps. D. Five big letters.

3.Which of the following is not true according to the passage?

A. Specific numbers should be included in the goals you set.

B. You should begin with small steps while achieving a goal.

C. In order to make the goal fit for you, you should be careful.

D. More time should be given for you to achieve your goal.

1.C 2.B 3.D 【解析】本文介绍了设定目标的聪明方法:1、你最好使你的目标更加详细和准确;2、不要以"健康"或"压力小"为目标;3、努力实现目标;4、选择你真正感兴趣的目标;5、你要清楚你心里有多少时间给自己去实现目标。 1.主旨大意题。根据短文中的句子For example, instead of setting a goal (目标): of “I want t...

During rush hours, you never know when a bus or a taxi might come. Walking might be too tiring. If it’s about two or three miles away, which kind of transportation will you choose? 1.

Bike shares are a growing convenience in many cities around the world. 2. Riders usually have to pick up a bike at a self-serve station and return it at another station later. However, a Chinese bike-sharing company called Ofo, is bringing this idea to a new level.
