The Great Barrier Reef is the result of millions of years of continental (大陆的) shifts, sea-level changes, and layers of coral (珊瑚) growth. The Reef was built over millennia (数千年) by coral attaching itself to existing dead coral, as it continued to reach toward the light. Like most living things, coral needs the sun to survive and generally lives in shallow waters, where enough sunlight can penetrate (穿透) the water. Sea levels began to rise at the end of the last most recent ice age, about 14,000 years ago. As a result, the previously exposed Reef was covered by water and the coral expanded along the length of the newly revived Reef.

Climate change is having a dangerous impact on this natural wonder. Although coral and algae (海藻) have evolved despite climate change, allowing them to survive, coral has begun producing products that are poisonous to the Reef and block the growth of algae. Additional concerns include the overwhelming amount of pollution and chemical runoff into the water which harms the already affected coral and reduces biodiversity.

The Great Barrier Reef is well known as one of the best diving destinations in the world. You can do your part to help scientists preserve the Reef’s ecosystem while visiting. By paying a visit to the Reef, visitors pay a reef tax that will be used for the management and conservation of the Reef. A lesser-known contribution visitors can make to Reef preservation is signing up for REEFSearch. After signing up, you’ll be sent a field guide that will teach you how to collect information that scientists can use to study the Reef’ s health. During each dive, using the information sent to you, you will look for key species, check for coral conditions, and make note of any garbage found near the Reef. These small contributions can ultimately have a large impact and save one of the great wonders of the world.

1. Why does coral live in shallow waters?
A.It must coexist with algae.B.It needs sufficient sunlight.
C.It has to stick to dead ancestors.D.It has to avoid deep-sea pollution.
2. What drove the coral to stretch across the new Reef?
A.The rise of sea levels.B.The exposure of it to air.
C.The change of its habitat.D.The threat from its enemies.
3. What is an impact climate change has on the Reef?
A.Coral cannot survive.B.Algae become harmful.
C.Algae cannot be seen on the surface.D.Coral produces something poisonous to the Reef.
4. Which of the following should you do after signing up for REEFSearch?
A.Study the Reef’ s formation.B.Find new habitats for coral.
C.Gather information on the Reef’ s health.D.Search for dangerous species around coral.

文章大意:这是一篇说明文。文章主要介绍网站会造成排放,并且网站设计者很少考虑网站的可持续性。作者呼吁创建可持续的网站,以减少排放。

【推荐1】No trees are seemingly cut down every time you search something or read a social media post on your phone or laptop. But websites alone do create emissions (排放)—internet usage is responsible for almost four percent of global emissions. That might not seem like a lot, but it is equivalent to about the same emissions caused by global air travel. That percentage is predicted to almost double by 2025 according to a post by Brussels-based energy magazine Energuide. And internet usage is on the rise—as the pandemic pushed many jobs and education online, internet usage went up as high as 40 percent.

The emissions caused by websites come from the hosting company that ensures that websites are up and running when users search for them on their server. By working with an environmentally sound server like Green Geeks, A2 Hosting, and Host Papa that focuses on renewable energy or lowering their energy usage, websites become more sustainable, Wired UK reported. Something as simple as using fewer images on a web page also helps lower emissions. Another way to reduce emissions is to have simply designed websites with little to no moving images like gifts.

Another aspect of creating more sustainable websites means raising awareness, or letting servers or customers in need of new web design know that it’s even an option for them. Some major search engines like Google have promised to reduce their tech centers’ water usage and to rely on more sustainable energy to run their search engines and other online products like Gmail and Google Docs.

Baruch Labunski, CEO of Toronto-based SEO company Rank Secure, explains that when many clients work with the company to have their websites designed, they don’t often think about sustainability. Companies like Rank Secure make a point to have sustainability as part of their process when working with businesses who want help with web design by relying on more sustainable data centers.

Of course, lowering the greenhouse gas footprint of your website is just the start of building up a sustainable company. Just relying on some renewable energy to have an eco-friendly website doesn’t make a company automatically eco-friendly.

“We need to think about the overall impact of our businesses.” says Labunksi. “If your business manufactures or even uses singleuse plastics, then your website’s carbon footprint shouldn’t be your primary concern.”

1. To create more sustainable websites, the hosting company should_________.
A.meet the data needs
B.design new websites with more gifs
C.work with an eco-friendly server
D.improve the education online
2. What can we learn from paragraph 3 and 4?
A.The clients should raise awareness and consider sustainability.
B.Rank Secure has no sustainable awareness when working with business.
C.Creating more sustainable websites can provide the only option for clients.
D.All major search engines promised to reduce their tech center water usage.
3. The passage is written to__________.
A.evaluate the methods to reduce emissions
B.inform readers the harm of overusing websites
C.encourage search engines to lower the energy usage
D.call for building up sustainable companies of emission reduction

文章大意:这是一篇说明文,文章讲了各国乘客在飞机上的表现。
【推荐2】阅读理解
阅读下列短文,从每题所给的四个选项 (A 、B 、C 和 D )中,选出最佳选项。

       A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.
       According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.
       The Airline Passenger Experience Association(APEX) spoke to around 1,500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia and Brazil.
       The results found Chinese travelers are most likely to nod off once the seat-belt sign switches off. They are also the first to take out their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively — when not drinking — choosing to work while flying at 35,000 feet.
       Meanwhile, Brits and Germans are the best at making chat with random strangers — spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via email, messaging apps or social media.
       Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection of in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers.
       The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements.” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey.” he added.
1. What can you probably see in the flight according to the passage?
A.Brazilians choose to drink.
B.Americans do in-flight shopping.
C.Germans chat to kill the time.
D.The Chinese switch off the seat-belt sign.
2. When on board the plane, ______.
A.passengers from one nation have little in common
B.most passengers like to read in-flight magazines
C.more than half of the passengers don’t enjoy plane food
D.most people tend to use in-flight time to have a good sleep.
3. What can we learn from the last paragraph?
A.Flyers care little about entertainment.
B.Flyers are not satisfied with the improvements.
C.Flyers are expecting better flight experiences.
D.Flyers have more and more demands from airlines.
4. What’s the purpose of the passage?
A.To entertain readers with interesting stories.
B.To encourage people to behave well in public.
C.To criticize impolite behaviors on the plane.
D.To inform readers of the results of a survey.

文章大意:这是一篇说明文。文章主要介绍了一项新发现,随机选择可能会成为我们的偏好,这项发现能够解释为什么成年人在相同的事情之间做出选择时会产生无意识的偏好。

【推荐3】When making choices, people assume that they pick what they like. However, research suggests that we like something strictly because we have chosen it. In other words, we dislike things we don’t choose. And this phenomenon has existed since we were babies.

In an experiment, US researchers brought several 10-to-20-month-old babies into a lab and gave them two same bright and colorful soft blocks to play with. They set each block far apart, so the babies had to crawl (爬) to one or the other — a random choice. After the baby chose one of the toys, the researchers took it away and came back with a new option. The babies could then pick either the toy they didn’t play with before, or a brand new toy. It turned out that the babies reliably chose to play with the new toy rather than the one they had not chosen.

In follow-up experiments, when researchers instead helped choose which toy the baby would play with, the phenomenon disappeared. “As if they were saying, ‘Hmm, I didn’t choose that object last time, because I guess I didn’t like it very much,” said Lisa Feigenson, co-author of the study.

This is a very important phenomenon in life, Feigenson noted. Adults will less like the thing they didn’t choose, even if they had no real preference in the first place. It looks like babies do just the same.

It shows that the act of making choices changes how we feel about our options. The random choices might become our preferences. “They are really not choosing based on whether they are novel or what they prefer,” said Alex Silver, co-author of the study.

This new finding explains why adults build unconscious preference when they make choices between the same things. Justifying (证明有道理) choice is somehow fundamental to the human experience. “I chose this, so I must like it. I didn’t choose the other thing, so it can not be so good. Adults make these inferences unconsciously,” Feigenson said.

1. What is the purpose of the experiments?
A.To test whether people choose what they like.
B.To see why babies prefer new toys to old ones.
C.To explain how babies and adults make choices differently.
D.To study if too many choices could create problems for people.
2. What can be learned from the experiments?
A.Babies prefer bright and colorful toys.
B.Babies’ preference largely affects their choices.
C.Babies prefer adults to help them make choices .
D.Babies’ previous random choices affect their preference.
3. Why is the new finding important in life?
A.It entirely changes our attitude to our choices.
B.It helps us make wise decisions in a consumer culture.
C.It promotes the relationship between adults and babies.
D.It helps us understand our unconscious preference for choices.
4. What can be the best title for the text?
A.Babies like what they chooseB.Random choices matter
C.Too many choices puzzle the adultsD.Preference affects the choice
