Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.
Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light(紫外线), which is present on many flowers and guides butterflies to honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae(触角), feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.
Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations(振动).
Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.
1.What can we learn from the 2nd paragraph?
A. Butterflies have good eyesight.
B. Butterflies can see in all directions and don't need to turn heads.
C. Butterflies are sensitive to bright colors including red and yellow.
D. Butterflies cannot sense the ultraviolet light.
2.How do butterflies hear sounds?
A. Using their feet to sense the vibration of things
B. Using their ears to listen directly
C. Using their wings to sense the sound vibrations
D. Using their antennae to judge the sound
3.Why do female adult butterflies carefully choose the host plants?
A. To find high-qualified honey.
B. To have a good place for living.
C. To make it easier for them to hide from the enemies.
D. To find a proper place for their eggs.
4.What does the last paragraph imply?
A. There’s a long way to understand butterflies well
B. Butterflies give great help to human beings
C. Butterflies are the most beautiful insects in the world

The beautiful oceans that cover three-quarters of our planet are home to some of our most valuable natural resources. However, while our knowledge of outer space is quite wide, the same cannot be said about the deep waters, thanks to the fact that any attempts to monitor them have either been too awkward or too expensive. Now, California-based Liquid Robotics has come up with an invention that is both economical and easily used across the waters.
Called Wave Glides, the autonomous robot that resembles a surfboard consists of two interconnected sections - on the surface is a glider(滑翔机)fitted with solar panels, battery and sensors. Right below underwater is a navigation(航行) glider.
The robot travels at a snail’s pace gathering data. This data is quickly sorted by its solar-powered computer chips and then sent ashore for analysis. This robot contains no battery that needs recharging. It is a zero emission (排放)device that uses wave energy to push itself forward.
The company is working towards making the robot even more autonomous than it currently is. As it now stands, while the robot can sense a danger such as a ship or a shark, it does not have the ability to move away. Liquid Robotics wants to change that and program the robot so that it has the ability to move away from danger.
To encourage the general public to get involved with the informative data collected by Wave Glider, the company is planning to launch four of the robots on a yearlong trip across the Pacific. Two will head for Tokyo and two for Sydney. All the data they collect will be posted online and the person who comes up with the most innovative interpretation will be awarded a prize.
1.What can we infer from Paragraph 1?
A.It costs less to explore the sea than outer space. B.Outer space has more resources than the oceans
C.People do not have as much knowledge of oceans as space. D.Three quarters of natural resources come from the oceans.
2.What do we know about Wave Glider?
A.It is eco-friendly. B.It can be used as a surfboard.
C.It’s shaped like a snail. D.It uses solar energy to move.
3.What change is most likely to be expected of Wave Glider?
A.Traveling more quickly. B.Sensing danger autonomously.
C.Analyzing data underwater. D.Keeping itself away from danger.
4.Why will four robots be launched on a yearlong trip?
A.To find more natural resources. B.To collect data around the world.
C.To get people informed of collected data. D.To test their ability to work underwater.
5.What is the author’s purpose in writing the text?
A.To promote an online contest. B.To call on people to explore oceans.
C.To introduce a new invention. D.To share the data collected in oceans.

Are you a volcano lover? Here is a list of some of the world's most beautiful volcanoes
that our travel agency can offer you to visit. Don't miss them!
Mount Mayon, the Philippines
Located about 450 km southeast of Manila on the island of Luzon, Mount Mayon is the
most active volcano in the Philippines; a September 2014 eruption forced thousands to flee the
area. Those who hike the volcano are rewarded with views of the towns in the Albay province
and the Pacific Ocean. But even those who prefer the view from a distance have a historical
good point at the Cagsawa Ruins, once an 18th Century Franciscan church that was destroyed
by an 1814 eruption.
Kilauea and Marina Kea, Hawaii
Hawaii's volcanoes are known for their active eruptions and extraordinary scenes. Mauna Kea is around one million years old, while Kilauea is the youngest volcano in Hawaii and has
been erupting continuously since 1983. The lava falls straight into the sea, creating fantastic
forms of black rocks and smoke clouds.
Mount Kelimutu, Indonesia
Kelimutu's three mysterious crater lakes attract both scientists and tourists to the island
of Flores in Indonesia's East Nusa Tenggara province. One is emerald green (翡翠绿), another
dark red, and the third pitch black. Scientists say the lakes take on such colors because the
volcanic gases met the lakes' minerals centuries ago.
1.People who hike Mount Mayon can enjoy the following EXCEPT ______.
A. views of the towns in the Albay province
B. views of the Pacific Ocean
C. views of the Cagsawa Ruins
D. views of Indonesia's East Nusa Tenggara province
2.According to the text, Kilauea_____________________.
A. is an active volcano
B. stopped erupting in 1983
C. is the youngest volcano in the world
D. forced thousands to flee in 2014
3.The colors of Kelimutu's three mysterious crater lakes are due to_______________.

Climate change,pollution,overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze.India’s Ganges and Africa’s Nile.WWF said on Tuesday.At the global launch of its report “World’s Top 10 Rivers at Risk”,the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic(水生的)life.
“If these rivers die,millions will lose their livelihoods,biodiversity(生物多样性)will be destroyed on a massive scale,there will be less fresh water and agriculture,resulting in less food security,”said.Rayi Singh,secretary—general of WWF—India.The report launched ahead of “World Water Day” today,also cited the Rio Grande in the United States,the Mekong and Indus in Asia,Europe’s Danube, La Plata in South America and Australia’s Murray—Darling as in need of greater protection.
Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up.Dams have destroyed habitats and cut rivers off from their flood plains.while climate change could affect the seasonal water flows that feed them,the report said.Fish populations,the top source of protein and overall life support for hundreds of thousands of communities worldwide,are also being threatened, it found..The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization,damming and huge influxes(流入)of sediment(积淀)from land conversion.
Climate change,including higher temperatures,also means serious consequences for fishery productivity,water supply and political security in Africa’s arid Nile basin.Tributaries(支流)flowing into the Ganges are drying up because of irrigation,WWF said.
1.hat is the text mainly about?
A.Saving fresh water in our life. B.How to protect our rivers.

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim(受害者)of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve(保护区)itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average(平均水平) of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment(投资) in such reserves at all levels.
1.What do we know about the IUCN?
A. A union for listing animals and plants on the earth
B. A group of volunteers who are interested in wildlife
C. An organization concerning the protection of rare species' survival
D. A government made up officials, scientists and experts
2.What can be concluded from the passage?
A. All the protection methods can’t work.
B. The IUCN does most of the protection.
C. The efforts China makes has paid off.
D. Enough is done in wildlife protection.
3. Which of the following is not the cause of the disappearance of the animals?
A. Bad weather B. Over-hunting C. Warmer oceans D. Habitat destruction
4.Which of the sentence is NOT true?
A. China has been paying great attention to protecting the natural resources.
B. China has set up a lot of natural reserves.
C. The natural reserves in China cover more than 15 percent of the nation's land area.
D. The rate of China's natural reserves is lower than the average of the world.
