Traditionally，robots have been hard， made of metal and other rigid materials.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 （章魚）.

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 a 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've 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 stilla 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-and-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.Whatis the special feature of the Octobot？

A. It's very small. B. It’s made of metal.

C. It’s soft. D. It's like an octopus.

2.Whatistheweaknessof traditional robots？

A. They'rehard to control. B. They're too heavy to move. C. They can't predict conditions. D. They can't always behave well

3. Which is the most challenging part in building the Octobot？

A. Its silicone body. B.Its complex structure. C. Its precise movements. D. Its flexible power source

4.What is the possible application of the Octobot according to the text？

A.Medical research. B. Life rescue. C.Machine operation. D. House cleaning

Nature hasalot tooffer._ Herearesomevaluable life lessons.

Respect your roots. With time， a young tree grows into full-grown one; something that was so tiny and delicate develops into a strong tree capable of supporting others.

Let the sorrows （傷心事） disappear. If you cut a hole in the tree， it will grow around it. Whatever may come in its way， a river will continue to flow. Similarly， whatever sorrow may break your heart， know that life goes on._ 3

Learn to coexist peacefully. Nature provides every creature a chance to exist， however big or small it may be._ 4 The tiger eats the antelope; without the antelope， the tiger may not survive.Likewise， without tigers， the overpopulation of antelopes may cause them to starve to death.

5 _Just as the icy cold snow melts in the warmth of spring to give birth to fresh green leaves，come autumn these leaves age into shades of gold only to be once again buried in the cold winter.

When Sarah Lee was a child， she loved to watch the birds in her backyard and wonder how they could fly so effortlessy. As she grew older， Sarah became interested in the science behind flight and decided to study aerospace （航空航天） engineering in college.

After graduation， Sarah began working for a company that designed airplanes. However， she soon realized that the traditional methods of airplane design were not always efficient or sustainable. She began to wonder if there was a way to design airplanes that simulated the natural world.

Sarah started to study birds and insects， observing how they were able to fly with such grace and efficiency. She asked questions like： How do birds adjust their wings to different wind conditions？ How do insects use their wings to hover in place？

With this knowledge， Sarah began to design airplanes that incorporated biomimicry， or the imitation of nature. She created wings that could adjust their shape based on wind conditions， just like a bird's wings. She also designed planes that could hover in place， like a dragonfly.

Sarah's designs were a hit. Her company began to produce airplanes that were more efficient and sustainable than ever before. They used less fuel and emitted fewer pollutants into the air.

Sarah now travels around the world， giving talks on the benefits of biomimicry in engineering. “Nature has been solving problems for millions of years，” she says.“We can learn a lot from the natural world if we just take the time to observe and ask questions.”

1. What made Sarah Lee major in aerospace engineering？

A.Her fascination with airplanes. B.Her interest in flight science.

C.Herchildhood dream. D.Her love for watching birds.

2. The underlined word “simulated’ in Paragraph 2 probably means“

A. monitored B.imitated C. resembled D. pretended

3.What is one example of biomimicry in Sarah's airplane designs？

A.Landing devices that resemble insect legs.

B.Engines that run on renewable energy sources.

C.Bodies that mimic the structure of a bird’s nest.

D.Wings that adjust their shape based on wind conditions.

4.What can be inferred about Sarah'scareer goal according to the text？

A. To become a pilot. B.Tostudybirdsand insects. C. To design effcient airplanes. D. To be an aerospace engineei

Many of us are disgusted （厭惡的） by spiders， or even afraid of them.But do you know that a spider's natural color may have many practical applications in our daily life？ For example， it can inspire a new shade of blue textiles （紡織品） and offer a solution to the glare on the screen of your phone when you're out in the sun.

This color is a shade of blue， inspired by the cobalt blue tarantula—a species of spider that is native to the rainforests of Southeast Asia. What surprised scientists who observed the eight-legged furry spider was that its color did not change at all， even when viewed from diferent angles.

A team of scientists， led by Bill Hsiung from the University of Akron in Ohio， have been studying tarantulas for some time.Blue is a rare color in the animal kingdom. The researchers set out to find the exact nature of this blue.They found that the outer body of the tarantula is covered by tiny crystalline （晶狀的） structures. These structures act like a mirror and when light strikes them， they reflect only one particular wavelength of light-blue. This kind ofnatural color is referred to as the “structural color”.

Usually， when colors are viewed from different angles， they appear different because of how light is reflected. This is because of a phenomenon known as iridescence （虹彩）. However， the blue color produced by tarantulas appears the same from all angles. It is the tiny crystals on the tarantula'sbody arranged in a flower-like shape that reduce iridescence.

Scientists have known about structural colors for a while，but they have not seen them used for dye （染料）. With a clearer understanding of how“structural colors” work， scientists can now create a color similar to the tarantula blue to dye textiles and other products.

5.What is special about the cobalt blue tarantula？

A. Its color is unchangeably blue. B. Its smell is naturally disgusting.

C. Its furs can be made into textiles. D. Its legs look crystal clear in the su.

6.What can we learn about the tarantula's crystalline structures？

A. They shorten the wavelength of light. B. They merely reflect the light of blue.

C.They determine the size of a tarantula. D. They absorb much light on a tarantula's body.

7. What is the author's purpose in writing Paragraph 4？

A.To introduce the tarantula's body structures. B.To explain the theory of the structural color. C.To show the phenomenon of color iridescence. D.To discuss the importance of reflection angles to colors

8.What is the best title for the text？

A.A Color Inspired by a Spider B. The Development of Blue Textiles C.The Cobalt Blue Tarantula—A Rare SpiderD.A Spider with Structural Colors Discovered

On a spring morning， I was talking with my parents in the yard when I saw one swallow flying toward our house. When I got closer， I saw it carrying mud with its mouth. It was then that I realized it would build a nest under our roof.

I noticed that it could only carry a little mud at a time， which made me doubt whether it could complete the task. However， it kept carrying mud every day and after three days，a beautiful nest was completed. Having such a neighbor really made my family happy.

From the swallow I learned that we can realize our goal as long as we are determined， anc have the spirit of perseverance though it may seem impossible to achieve that in the beginning.
