What do you usually do when a flying insect lands on your arm？You may blow it away．But what if that insect is a ladybug（瓢虫）？It is possible that you would let it stay．What is it about ladybugs that we like？
   Farmers once thought ladybugs were a good lucky sign．A ladybug in the field meant the crops would be successful and that the weather would be good．The farmers may have thought too highly of such a small bug，but in fact ladybugs do help out with the crops．They eat harmful insects．
   Actually，it is not the adult ladybug that eats other insects．It's the baby ladybug．When the baby ladybugs hatch（孵化），they are very hungry and will eat mites，aphids，mealybugs，green flies，and other crop-destroyers．In the 1800s，ladybugs were brought all the way from Australia to California and set free among orange trees that were dying from being eaten by insects．They completely saved all the trees．
   Ladybugs go about their daily business without worrying much about anything．Very few birds or insects will eat a ladybug because it gives off a dangerous fluid（液体）．Ladybugs also protect themselves by playing dead．They fall off leaves and stay still until their attacker goes away．
   So the next time you see a ladybug，think about what it may be doing．Maybe it is off to save an orange tree．Maybe its next move will be to roll off a leaf and play dead or stand up to a bird about 100 times its size．Maybe it's letting you know that the weather will be good tomorrow．Who knows？Ladybugs are special that way．

1．You've heard that plastic is polluting the ocean—between 4.8 and 12.7 million tonnes enter ocean ecosystems every year.But does one plastic straw or cup really make a difference？Artist Benjamin Von Wong wants you to know that it does.He builds massive sculptures out of plastic garbage，forcing viewers to re-examine their relationship to single-use plastic products.
   At the beginning of the year，the artist built a piece called "Strawpocalypse，" a pair of 10-foot-tall plastic waves，frozen mid-crash.Made of 168，000 plastic straws collected from several volunteer beach cleanups，the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City，Vietnam.
   Just 9% of global plastic waste is recycled.Plastic straws are by no means the biggest source（来源）of plastic pollution，but they've recently come under fire because most people don't need them to drink with and，because of their small size and weight，they cannot be recycled.Every straw that's part of Von Wong's artwork likely came from a drink that someone used for only a few minutes.Once the drink is gone，the straw will take centuries to disappear.
   In a piece from 2018，Von Wong wanted to illustrate（说明）a specific statistic：Every 60 seconds，a truckload's worth of plastic enters the ocean.For this work，titled "Truckload of Plastic，" Von Wong and a group of volunteers collected more than 10，000 pieces of plastic，which were then tied together to look like they'd been dumped（倾倒） from a truck all at once.
   Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

（1）What are Von Wong's artworks intended for？

A．Beautifying the city he lives in.
B．Introducing eco-friendly products.
C．Drawing public attention to plastic waste.
D．Reducing garbage on the beach.
（2）Why does the author discuss plastic straws in paragraph 3？

A．To show the difficulty of their recycling.
B．To explain why they are useful.
C．To voice his views on modern art.
D．To find a substitute for them.
（3）What effect would "Truckload of Plastic" have on viewers？

A．Calming.
B．Disturbing.
C．Refreshing.
D．Challenging.
（4）Which of the following can be the best title for the text？

A．Artists' Opinions on Plastic Safety
B．Media Interest in Contemporary Art
C．Responsibility Demanded of Big Companies
D．Ocean Plastics Transformed into Sculptures

2．Modern day robots may not be as entertaining as R2 D2 or the robot from Lost in Space，but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.
   Robots make great explorers on planets，the moon，and other landing areas.Aside from the earth，just about every surface in the solar system is unsafe for humans to explore.The air on most other planets is insufficient for humans to breathe，making it necessary to wear a space suit and oxygen equipment.The temperatures on these surfaces are much too hot or much too cold for any humans to withstand.Plus there would be complications with radiation，weather，and a lack of gravity.Robots have much less limitation in these areas and can survive much longer under these conditions.
   Robots are designed for collecting scientific data.Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently.Important scientific projects from detecting minerals，analyzing ground samples，to finding water are all performed much quicker and accurately by robots.
   The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work.In order to successfully send humans into space we would need to build a vehicle that can not only carry humans，but also enough food and water to keep them alive for the duration of the trip.Moreover，robots have no problems working for hours on end.Robots never complain，they don't require food or water，and they never need a bathroom break.
   Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space.Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars.They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.

（1）Which of the following would be the best title for the passage？

A．The Development of Robots
B．The Discovery of Space Exploration
C．No Robots，No Space Exploration
D．Robots Are Used in Space Exploration
（2）According to the passage，which of the following is NOT true？

A．The use of robots in space exploration costs more than the use of humans.
B．It is dangerous for humans to explore other surfaces in the solar system except the earth.
C．Both Spirit and Opportunity have found the evidence of water on Mars.
D．Many different types of robots have explored the space successfully.
（3）The underlined word "withstand" most probably means "

".
A．remain
B．bear
C．defeat
D．develop
（4）What is the writer's attitude in this passage？

A．Negative.
B．Persuasive.
C．Subjective.
D．Objective.

3．The forest of today will not be the forests of tomorrow.Rising temperatures，trees being cut down，development and climate-change-caused disasters are changing the very makeup of the Earth's forests，new research published in Science finds.
   Older，bigger trees are being lost at an alarming rate，making the planet's forests shorter and younger.The change is being driven at different rates by different causes in different places，the study's authors say，but the consequences will be global.
   Old growth forests absorb and store massive amounts of climate-warming CO₂.They provide habitats for rare and endangered species and promote rich biodiversity.Researchers found that the world lost roughly one-third of its old growth forests between 1900 and 2015.In North America and Europe，they found that tree mortality（死亡率） has doubled in the past 40 years.
   "Warming temperatures，wildfires，logging and insect outbreaks were among the many causes of the decline，" says Nate McDowell，the study's lead author. "What's perhaps more concerning is that the trajectory（发展轨迹） of all these disturbances is generally increasing over time and is expected to continue increasing in the future." he says.
   McDowell's focus is on how trees are affected by rising temperatures，arguably the biggest driver of forest change.To get a broader understanding of how forests are changing globally，he brought in more than 20 other researchers in different fields.Together，they examined more than 160 previous studies about tree mortality and its global causes，applying current satellite data and modeling to create a look at the Earth's changing forests to date.
   "It's not a shock，but it's very sad，" says Kristina，an ecologist and leader of the ForestGEO Ecosystems &Climate Program who helped with the research. "We as a human society are hitting these forests so rapidly with so many different changes that they can't keep up." she says.

（1）What can we know from the figures in the paragraph 3？

A．More trees should be planted in no time.
B．We are losing old growth forests quickly.
C．Forests are important habitats for wildlife.
D．Different trees can absorb CO₂ differently.
（2）What can we say about McDowell's research？

A．Timely and long-standing.
B．All-sided and careful.
C．Time-limited and regional.
D．Traditional and extensive.
（3）What's Kristina's attitude towards the findings of the research？

A．Worried.
B．Optimistic.
C．Supportive.
D．Indifferent.
（4）What's the writer's purpose of writing the passage？

A．To call on people to plant more trees.
B．To discuss the influence of climate change.
C．To warn against the loss of old growth forests.
D．To compare forests of today with those of the future.
