Before war and time destroy more of our important cultural sites, we need to save them in 3-D digital libraries. Across 163 different countries, 1,000 natural and cultural historic places make up our most precious human heritage, which UNESCO calls World Heritage Sites.

We lose a little of that heritage every day. War, climate change and pollution have a bad effect, as do wind and rain. The $4 million a year that UNESCO spends on preservation is not nearly enough to take care of even the four dozen sites considered at approaching risk of being lost forever. Now there’s a better choice. New digital-conservation technologies let us hold on to them, at least virtually(虚拟的), through 3-D scanning, modeling and digital storage. Such projects can be accomplished through cooperation between governments, universities, industry and non-profit organizations.

To make a 3-D model, a laser(激光) scanner bounces light off an object and records the results. To reproduce every corner and opening, the scanner collects overlapping(重叠的) images from all possible angles. A computer then sews them together into one large surface image and draws lines from one point to another to create a wire-frame model. High-resolution digital cameras add color and texture. When fully put together, the models can be viewed, printed or operated.

These scans do more than preserve a memory in a database. With highly accurate measurements, archaeologists(考古学家) can find hidden passages or reveal ancient engineering tricks. School kids can explore places they might otherwise never see. And when a site is destroyed, the scans can even be used to reconstruct what was there. That has already happened for one World Heritage Site, the Kasubi Tombs in Uganda. Built of wood in 1882, they were destroyed by fire in 2010 and rebuilt in 2014, based in large part on 3-D models made in 2009. More than 100 World Heritage Sites have been already preserved as 3-D models, and conservationists are racing to record as many more as possible.

1.How does the author show the necessity for 3-D digital libraries in the first two paragraphs?

A.By listing the threats to our human heritage.

B.By introducing some damaged historical sites.

C.By quoting some experts’ views on heritage protection.

D.By explaining UNESCO’s research on World Heritage Sites.

2.What is Paragraph 3 mainly about?

A.The function of a laser scanner. B.The reflection of light off an object.

C.The process of making a 3-D model. D.The development of 3-D digital technology.

3.What do we know about the Kasubi Tombs in Uganda?

A.It is metal-framed. B.It is still in its original condition.

C.It was once destroyed in an earthquake. D.It was reconstructed thanks to 3-D models.

4.What does the author intend to say through this text?

A.Never ignore the destructive power of war.

B.Take action to reduce pollution in historic places.

C.Take advantage of 3-D technology to keep history.

D.Invest more money to preserve World Heritage Sites.

The average American male consumes 100 grams of protein daily — almost double the necessary amount. This overconsumption isn’t able to continue for long. Besides, there’ll be an extra 2.5 billion people by 2050. Therefore, the United Nations will need to increase as many as 70% food projects by 2050 to solve this problem.

To survive, we need to change the way we farm and eat. Experts say algae(藻类植物), which can offer lots of protein, could be a possible solution. Meat, which is our main source of protein, uses a lot of our limited resources, like water and land, not just for the animals but also to grow their food. But the green slimy algae that lives in oceans, ponds and aquariums can grow fast, is packed with nutrition and needs next to nothing to grow. It can even grow in a desert. That’s surely a big deal.

The wellness company iWi is now growing a type of algae on a large scale. The farm has green seas as far as the eye can see. The entire farm covers 900 acres, 98 of which is currently being cultivated and operates all year around.

The algae on the farm is grown in long ponds called “raceways”, and an engine constantly stir water to make sure the algae is exposed to the sunlight. CO2 and a tiny bit of fertilizer are then pumped into the water to help the algae grow.

The fresh algae grown on iWi’s farm is a far cry from the unpleasant taste in your mind. That’s because not all types of algae smell or taste like pond scum(浮垢). And the farm’s algae simply tastes salty and gives hope that people would willingly eat this.

“The protein we’re producing is not going to be green,” said Miguel Calatayud. “Our protein powders will be difficult to be noticed when added to other foods. It will be in every single food that you eat on an everyday basis. Algae is going to be part of a regular food chain for us. It’s going to be a great thing for all of us and for our entire planet.”

1.Why will the UN need to increase its food projects?

A.To deal with over-population in the world.

B.To double Americans’ protein consumption.

C.To ensure Americans’ 100 grams of protein daily.

D.To solve the possible protein shortage worldwide.

2.What’s the algae’s advantage over meat?

A.It contains more protein. B.It can grow in the desert.

C.It is much more delicious. D.It is environmentally-friendly.

3.What does the underlined part in Paragraph 5 mean?

A.Is considered as. B.Is different from.

C.Is responsible for. D.Is applied to.

4.We can infer from Miguel Calatayud that the new algae_____.

A.can benefit the demand for protein unconsciously

B.has a surprisingly good effect on people’s health

C.has a different color from the common algae

D.can change the future of our eating habits

Apples are packed with amazing health benefits: weight loss, heart protection, lowering your risk of illnesses, and many more. Not only are they good for you, but they taste delicious too! The only problem is that the pieces we pack for lunch are always an unpleasant brown by the time we dig them out of the fridge. That’s because polyphenol oxidase (PPO) in the fruit experiences a chemical change with oxygen (氧气) in the air.

Luckily, there is an apple you can pick up at the store that won’t turn brown for a while―the Opal apple. Opal apples are naturally low in PPO, which means they’ll stay fresh and white long after you cut them. It has been tested that after sitting out unpacked for more than six hours, the apple had hardly any browning.

You may be wondering if genetic modification (转基因) plays a role in avoiding the fruit’s browning. In fact, you may even ask if Opal apples are safe to eat because they can do something most apples can’t. But according to the Opal website, they’re the first apples to be checked by the Non-GMO Project, the gold standard for certification (证明). “We understand that some people are concerned about genetically modified organism (GMO) products and felt it was important to make it clear that the natural nonbrowning characteristic is just that―natural,” said Keith Mathews, CEO of First Fruits Marketing.

The Opal apple is actually a cross between a Golden Delicious and a Topaz apple, and it has a sweet flavor. Plus, it still has all the health benefits every other apple has. Although FirstFruits Marketing does not show nutrition (营养) facts for the Opal apples, their nutrition value should be similar, if not the same, to every other apple. If you don’t like eating brown apples, you can consider going to the supermarket for some Opal apples.

1.How is the Opal apple different from other apples?

A.It has less PPO.

B.It helps lose weight.

C.It has the attractive smell.

D.It has few spots on its skin.

2.Why is the Non-GMO Project mentioned?

A.To show the popularity of Opal apples.

B.To show Opal apples meet the safety standard.

C.To show Opal apples have a special characteristic.

D.To show the concern for GMO foods.

3.What is the author’s attitude to the Opal apple?

A.Doubtful. B.Uncaring. C.Positive. D.Careful.

4.What is the best title of the text?

A.Opal Apples―with More Nutrition?

B.Opal Apples―on the Way to Be Popular?

C.Opal Apples―A New GMO Food?

D.Opal Apples Never Brown―But Are They Safe to Eat?

The United States space agency will send a spacecraft to explore the sun more closely than ever before on Saturday. NASA'S Parker Solar Probe（探测器）will fly through the hot solar atmosphere and come within just 6 million kilometers of the sun's surface.

The Parker Probe will get almost seven times closer to the sun than earlier spacecraft. To do this, it will fly past Venus（金星）seven times over seven years. Each pass will change the probe's orbit by providing a gravity push. It will move ever closer to the sun and straight into the corona（日冕）, the sun's outermost atmosphere.

By exploring the sun's corona, scientists hope to learn why it is hundreds of times hotter than the sun's surface. They will also study what drives the solar wind.

The project was proposed in 1958, the same year NASA was established. Now, "it's becoming a reality," said project manager Andy Driesman.

The Parker spacecraft has a 2.4 meter heat shield（护罩）that is 11 centimeters thick. It is made of two carbon sheets. The front has a white coating to reflect sunlight. It is expected to shine red when it experiences the extreme solar heat. Almost everything on the spacecraft will be behind this shield to keep its scientific instruments relatively cool.

Besides, the spacecraft will also be traveling at a high speed. The probe will reach 690,000 kilometers per hour in the corona. The spacecraft will make its first flight past Venus in early October. Its first pass by the sun is expected in November.

The Parker Solar Probe is the first NASA spacecraft to be named after someone who is still alive. Eugene Parker is a 91-year-old professor at the University of Chicago. He predicted the existence of solar wind 60 years ago. He plans to be at Cape Canaveral Air Force Station in the southern state of Florida to see the launch.

1.What's the advantage of the Parker Probe compared to the earlier ones?

A.It can change the orbit by flying past the sun.

B.It can get closer to the sun and into the corona.

C.It can study the effect of solar wind.

D.It can fly through the hot solar atmosphere without protection.

2.What can be inferred from the passage?

A.Human had little achievements in exploring the sun.

B.Eugene Parker is the first one to study the sun.

C.The Parker Probe has to get close to the sun with the help of Venus.

D.Human can get close to the sun's surface within 6 million kilometers today.

3.What can we learn about Eugene Parker?

A.He started NASA.

B.He foresaw the solar wind when he was 31.

C.He designed the Parker spacecraft.

D.He will study the sun using the Parker spacecraft.

4.Judging from the content, the passage most probably belongs to 　　　　 .

A.a story book B.an advertisement

C.a science fiction D.a news report
