    Trees are commonly cut down for wood and paper. 1.. The unique chemical process that trees and plants use to turn light energy from the sun into oxygen is known as photosynthesis (光合作用).

2.

The production of oxygen is a result of photosynthesis, but it is not the main purpose of this process. 3.. Plants create their own food through photosynthesis. During this process, a plant’s roots absorb water from the ground, and its leaves take in light energy and carbon dioxide. The plant uses these elements to make fats and proteins that are then used to maintain the plant’s life.

The process of photosynthesis

The first step in photosynthesis is using the sun’s energy. During this process, chlorophyll (叶绿素) absorbs the light energy of the sun. The energy from the sun then acts upon the water absorbed by the roots of the plant. Carbon dioxide sent into the atmosphere by animals and humans is then absorbed by the plant’s leaves and paired with the hydrogen to produce sugar. The sugar is turned into plant food. 4..

Threats to tree photosynthesis

5.. Today, only about 30 percent of Earth’s land is covered in trees. This is contributing to global warming since trees are necessary to consume the carbon dioxide in the atmosphere. Experts believe planting trees is vital in order to ensure the preservation of the delicate balance that enables photosynthesis.

A.The purposes of photosynthesis

B.The advantages of photosynthesis

C.In fact, oxygen is simply a by product

D.It is also responsible for giving plants their green color

E.During this process, extra oxygen is produced and released

F.The trees that change carbon dioxide into oxygen are disappearing rapidly

G.But the greatest value of trees comes from their ability to turn the sun’s energy into chemical energy

    Although air travel comes with jet lag, delays and awful food, it offers a brief digital detox—a precious few hours away from the wave of emails, messages and app announcements. But not anymore, In flight Wi-Fi is getting faster and cheaper, and is an increasingly common offering on budget and flagship airlines.

But how does in-flight Wi-Fi actually work? To simplify, there are two ways for an internet signal to reach your device when you’re up in the clouds. The first is via ground based mobile broadband towers, which send signals up to the aircraft’s antennas (天线). As you travel into different sections of airspace, the plane automatically connects to signals from the nearest tower, so there is (in theory at least) no interruption to your Internet. But if you’re passing over large areas of water or particularly remote zones, connectivity can be an issue.

The second method uses satellite technology. Planes connect to satellites in space (35,000 km above the planet), which send and receive signals via receivers and transmitters. Information is transmitted to and from your smart phone via an antenna on the top of the aircraft. These are the same satellites that are used in television signals and weather forecasting. Information is passed between the ground and the plane via the satellite.

All of that technology is expensive. The costs are usually passed on to customers. Over half of the world’s aircraft will be equipped with in-flight Wi-Fi within the next few years. It is set to become a billion-dollar industry by 2020. In the near future you’ll need to find a better excuse than “Sorry I missed your message—I was on a plane”.

1.What sends signals up to the aircraft’s antennas?

A.Internet companies. B.Ground-based receivers.

C.Budget and flagship airlines. D.Ground-based mobile broadband towers.

2.Who will pay for the in-flight Wi-Fi technology in the end?

A.Aircraft passengers. B.Satellite company.

C.Broadband towers. D.The local government.

3.What can we infer about in-flight Wi-Fi from the last paragraph?

A.It serves every customer. B.It has a bright future.

C.It develops very slow. D.It’s a high-tech industry.

4.What is the best title for the text?

A.How to Use In-flight Wi-Fi? B.Why Only Some Airlines Have In-flight Wi-Fi?

C.Why Is In-flight Wi-Fi Expensive? D.How Wi-Fi Works on a Plane?

    To me, Shakespeare is a bit of a touchy subject in the theatre industry. I believe Shakespeare’s plays to be the most challenging in terms of language. When you have challenging language, then understanding the plot and topics will become a challenge as well. It’s like a chain. If you don’t understand it from the start, it makes things hard later on and people tend to give up on it. Regardless of all of this, I believe Shakespeare is important in the sense that it’s where true theatre started. William Shakespeare is a name everyone knows regardless of whether you enjoy his works or not.

Many high schools or colleges put on at least one Shakespeare play every few years and I like that. I think it’s important to expose students to plays that are a bit more challenging than they used to be. Of course. it’s not easy to understand these plays but then think about the people who act in those plays. When acting, you have to understand your character and not only that, you need to completely know everything going on around you as well. So to understand the script (剧本) is one thing. but to act in a Shakespeare play is a whole another thing. How about memorizing the lines? That’s one of the hardest things actors have to get through. It is such heightened language that it’s almost like learning a foreign language. Shakespeare is tough and that’s what I think I love it the most. The challenge is understanding. Once you have that then you have room to play with it.

Therefore, if people walked into a Shakespeare play with more of an open mind, their experience would be so much better. There is a large amount of exploration and discovery in his plays and the experience can be really satisfying. It’s hard stuff, but it’s fascinating and we should be embracing it.

A.The challenging language. B.The variety of its topic.

2.What’s the author’s attitude towards putting on Shakespeare’s plays at colleges?

A.Critical. B.Cautious.

C.Favorable. D.Indifferent.

3.What does the text suggest people do when enjoying Shakespeare’s plays?

A.Act them out. B.Remember the lines in them.

C.Learn Shakespeare’s language. D.Enjoy them with an open mind.

4.What is the text mainly about?

A.The characteristics of Shakespeare’s plays.

B.The plots and topics of Shakespeare’s plays.

    Richard Dermer is a pizza shop owner. But he is better known for his hobby. As a extraordinary kite collector, people are impressed by kites covering the walls from all over the world when they walk into his pizza shop.

Dermer worked at Hideaway. He bought the pizza shop in 1960. Then, in 1970, his game-partner and manager at Hideaway was the first to market the Japanese version of the game Go in the United States. It was this game that led Dermer to kites, and from there he took off—eventually becoming president of the American Kiefliers Association.

Dermer now has a huge kite collection. He told Collectors Weekly, “Initially, I was a novice, but I enjoyed learning, trying to acquire more about kites. And the more I got into kite festivals and collecting kites, the more I discovered and the deeper the subject became.”

What Dermer’s collection and hobby brings to the United States is an international perspective and history on kite flying. In India, for example, kite flying is a fierce, sometimes violent sport, while in Thailand, kite battles reflect the war of the sexes between men and women. Kites were used in World War II, to distract German planes and for target practice.

When Dermer started stunt kite (特技风筝), it was pretty new. All the kites were triangular, and they all looked the same. But soon with his efforts, that changed. People could see kites of all shapes, sizes and colors flying in the sky. During the 1980s and 1990s kites went through quite a developmental stage where they were getting better and better as new lighter, stronger materials were being developed. Dermer even set up the new rules for judging these stunt kite competitions, which take into account how much control the flier has, and the difficulty of the moves.

1.What is Richard Dermer’s occupation?

A.A plane pilot. B.A food businessman.

C.A kite seller. D.A sales manager.

2.What does the underlined word “novice” in paragraph 3 mean?

A.Advanced person. B.Learned person.

C.Inexperienced person. D.Well-known person.

3.What can we learn about the kites from paragraph 4?

A.Kites are not popular in the USA. B.Flying kites is illegal in Thailand.

C.Kites played a part in World War II. D.Flying kites is an interesting sport in India.

4.With the efforts of Richard Dermer, kites became ________.

A.portable B.diverse C.available D.delicate
