How to stay focused in class
Being relaxed during class is a bad habit， and it is also bad to your grade． Focusing in class not only proves to teachers that you are a capable student but also shows that you have the ability to control yourself， which will be very important．
1. No matter how much you want to sit with your friends during the class， try your best to avoid them． Talking with friends around you is not going to give you the focus in class． This will get you into trouble．
Look at teacher and make eye contact． Your teacher is not just standing up there talking．2. Show the teacher that he or she has your full attention by looking them in the eye． This person should have your full attention at all times during class．
Take notes． By taking notes， you'll be able to "get into" the lesson． Write down key points as your teacher speaks． And listen to the key phrases such as "This is important" "This is the main idea" "This will be the test" etc．3.
Get involved in class discussions． This is a wonderful way to become a more focused， successful student． When a teacher asks a question， offer to answer it．4.This shows the teacher that you are listening carefully during the class．
Ask a question．5.This really shows your teacher that you want to be better， and can recognize the things you are having difficulty with． Chances are that someone else in the class has the same question （and was too afraid to ask!）． They'll be relieved， and so will you．
A． Avoid sitting with friends．
B． This can help you listen more attentively．
C． If he or she ask for an opinion， share your own．
D． Talking with friends makes you lose interest in class．
E． He or she is trying to give you an acceptable education．
F． The more quickly you answer， the more attention you pay．
G． If you don't understand something， never be afraid to ask．
What’s small, buzzes here and there and visits flowers? If you said bees or hummingbirds, you got it. You wouldn’t be the first if you mixed the two up. Now a group of researchers even say we should embrace our history of considering the two together in the same group. The way scientists study bees could help them study hummingbird behavior, too.
Scientists first compared the two back in the 1970s when studying how animals search for food. The idea is that animals use a kind of math to make choices in order to minimize the work it takes to earn maximum rewards. Researchers at the time focused on movement rules, like the order in which they visited flowers, and where flowers were located relative to others. It was “almost like an algorithm(算法)” for efficient searching, said David Pritchard, a biologist at the University of St. Andrews in Scotland. Hummingbirds and bees had similar solutions.
As the field of animal cognition(认知) appeared, hummingbird and bee research parted. Neuroscientists and behavioral ecologists developed ways to study bee behavior in naturalistic settings. Hummingbird researchers compared hummingbirds to other birds and borrowed methods from psychology to study their ability to learn in the lab. To be fair, hummingbirds and bees differ. For example, hummingbirds have more advanced eyes and brains than bees. Honeybees and bumblebees are social; hummingbirds typically aren’t.
But however they perceive(感知) or process information, they both experience similar information, Dr. Pritchard said. In day-to-day searching for food, for example, hummingbirds may rely on more of a bee’s-eye view than a bird’s-eye view. Like other birds, they rely on landmarks, distances and directions to make maps when travelling long distances, but they don’t use these cues to find flowers. Move a flower just an inch or so away from where a hummingbird thought it was and it will hover over the flower’s original location. Dr. Pritchard is investigating if, like bees, hummingbirds engage in view matching — hovering, scanning snapshots of a place to its memory and using those as references later.

Traditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot-one that draws inspiration from an octopus (章鱼).
Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search，rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots” the study’s authors wrote.
Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains (地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.
So researchers have been working on building soft robots for decades. They’re taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.
But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology’ Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”
1.What’s the special feature of “Octobot”？
A.It’s soft. B.It’s made of metal.
C.It’s very small. D.It looks like an octopus.
2.What’s the disadvantage of traditional robots?
A.They’re hard to control. B.They’re too heavy to move.
C.They can’t predict conditions. D.They can’t behave well all the time.
3.One of the biggest challenges is to build Octobot’s ________.
A.silicone body B.complex components
C.precise movements D.flexible power source
4.What’s the possible application of “Octobot”？

Alongside air and water, food is a necessity for human beings to survive and thrive. But it’s a lot more than that. As Mariette Dichristina of Scientific American wrote: “The most intimate (亲密的) relationship we will ever have is not with any fellow human being. Instead, it is between our bodies and our food.”
Nowadays, for most people in the world’s wealthiest countries, food is a hobby, an enthusiasm, and even something fashionable.
Turn on the TV in the US, UK or France, and you’ll find at least one channel feeding this popular obsession.
And most of us know at least one person who thinks of themselves as a “foodie”. It’s almost impossible nowadays to check our social media apps without at least two or three photos of delicious meals appearing on our screen.
But behind the fancy recipes and social media bragging (夸耀), many of us forget how much we take food for granted. This is why World Food Day is held each year.
Take Kenya for example. This east African nation has been suffering terrible droughts. The result is that people are beginning to starve. Children in particular are suffering, with some of them even dying.
This may seem shocking to know, especially as many cultures outside of Africa think of food in a completely different way. But even in the UK, families on low incomes are forced to use food banks—European organizations that hand out donated food to those who can’t afford to pay for it themselves.
So what can we do on World Food Day? One good way to spend it would be to feel humble and appreciate what we have. After all, food is essential for survival, but not everyone is as lucky as we are when it comes to dinner time.
1.According to Mariette Dichristina, what has the closest relationship with us?

Last year marked the 100th anniversary of the end of World War I. There were events around the world in memory of those who died in the conflict. We have picked out three of them in European countries. Let's take a look.
Belgium
In a park, the famous Belgian artist Koen Vanmechelen had an exhibition called Coming World, Remember Me. The work consisted of 600,000 individual(个别的) clay sculptures, one for each person killed during the World War. In the center of the exhibition was a big egg made of clay, symbolizing a new world.
UK
In a small town called Aldridge, almost 100 houses in one street were covered with 24,000 poppies and statues of soldiers. They stood for the men from the area who had been killed in the war. The flowers were chosen because of a poem written by the Canadian doctor John McCrea in 1915. They made people think of fields of blood.
France
The British artist Guy Denning arrived in La Feuille, a small town in the northwest of France, to stick life-size drawings of soldiers who never came back home. Armed with glue and a brush, Denning stuck his drawings carefully on walls. Before long 112 men, mainly young adults, were brought back to mind, if not to life.
1.What do we know about Coming World, Remember Me?
A.It's the name of an exhibition. B.It's a film about World War I.
C.It's a work standing for peace. D.It's a sculpture made of clay.
2.Why were poppies chosen to symbolize the dead soldiers?
