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

Rome is recognized across the globe for its classical artwork, but recently the city's street art has been drawing attention. While many urban artists stick to painting murals（壁画），one Italian sculptor is resisting the trend with his wonderful works made from an unusual material. Andrea Gandini, a native of Rome in his early twenties, has been recognized for his wood carvings of old tree trunks scattered across the city's landscape.

Gandini's Trocomorto, or "dead trunk" project, began in 2018, when the artist ran out of sculpting clay. That's when he noticed the remains of an old tree stump in his neighborhood. He realized that Rome was full of potential canvases（画布）just waiting to be given a new life. "Bringing trees back to life" is exactly how Gandini and others describe his art.

Due to years of poor care by the city, many trees became diseased and had to be cut down. This resulted in lots of old stumps that degraded the streets of Rome, which were costly to remove. However, they have been a perfect canvas of Gandini, who has completed over 50 carvings across the city.

Gandini gives each old tree trunk a face and personality of its own. By recognizing each formerly living tree as individual, he hopes to give them some dignity in death and respect each of them with their own headstone of sorts. For those that can't make the trip to Rome, Gandini documents his works of art on Facebook.

Gandini's “dead trunk" project reminds us of what Auguste Rodin says, "There is no lack of beauty in the world, but a lack of eyes to find it." All is beautiful in the eyes of the artist, for his keen eye sees through the heart of all living things. To discover its character is to pierce its outer form and touch its inner truth. This "truth" is also "beauty".

1.What has drawn people's attention recently in Rome according to the passage?

A.Its classical artwork. B.Its traditional murals.

C.Its street wood carvings. D.Its unusual material.

2.Which statement is NOT correct about Gandini's works?

A.They are full of life. B.They follow the trend of murals.

C.They beautify the city. D.They are appreciated by some artists.

3.What does Gandini try to put in his works?

A.Dignity and respect. B.Beauty and kindness.

C.Hope and personality. D.Death and art.

4.What can we learn from this passage?

A.Beauty is always around for keen eyes.

B.Inner truth is difficult to find.

C.We live in a world lacking beauty.

D.Grandini is a person who loves nature and truth.

There are some Christmas traditions between the United Kingdom and the United States.

Letters to Santa Claus

In the United States, kids usually write letters to Santa and put them in the mailbox. However, in England we throw them directly into the fire. We don't plan to make kids cry because burning the letters can send them to the North Pole where Santa can read your Christmas wishes in the smoke. It may seem strange but it does save on postage.

Hanging stocking

Traditionally, American kids hang stockings around the fireplace for Santa to fill with presents. But in the UK. we hang stockings around the bed; being surrounded by presents is a fantastic way to wake up on Christmas morning.

Christmas pudding

Americans prefer to have pumpkin and pecan pies for the Christmas dessert; while we British are fond of Christmas pudding. which is a cake flavored with dried fruits and spices.

Dealing with Christmas tree

We British chose to take down the Christmas trees and the decorations within 12 days of Christmas, because we hold the belief that keeping then beyond that time can bring bad luck. This is probably a tradition that Americans should consider adopting. I have seen people keep their old, brown, dry and withered Christmas trees until almost July 4.

1.How do the British people deal with "Letters to Father Christmas"?

A.Emailing them to Santa. B.Hiding them in the mailbox.

C.Putting them in the stockings. D.Throwing them straight into the fire.

2.Why do the British take down the Christmas tree as early as possible?

A.To stop it from drying B.To expect good luck.

阅读下面短文，根据其内容写一篇60词左右的内容概要。

We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft (手艺) no longer exists. One of the ways these people wrongly support their view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability (持久性). “Homes in those days were well-built,” they say. There is no doubt that these homes were well-built, but what these people have done is mix up the quality of material used in the house with the quality of the craftsmanship.

Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, more people can no longer afford solid oak stairways, although they were once fairly common in older homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better job than carpenters of old.

One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and power planes help them lay out a house better and make more precision cuts (精确切割) on the wood. Also, it is not uncommon any more to find carpenters with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs.

The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the carpenter of fifty years ago, but only if given proper material.

Trees are useful to man in three important ways: They provide him with wood and other products; they provide him shade;. and they help to prevent droughts（早灾）and floods.

Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important．In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind（固定）the soil, thus preventing it from being washed away easily；but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When the top-soil is gone, nothing remains but worthless desert.

Two thousand years ago，a rich and powerful country cut down its trees to build warships, with which to gain itself an empire(帝国）．It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation（饥荒）．

1.The most important service of trees to man is that___________．

A. they give them wood and other products      B. they give them shade

C. they help him prevent droughts and floods    D. they help him made money

2.In many parts of the world, forests slowly disappear because___________．

A. many trees have been cut down by man    B. man has not paid enough attention to planting trees

C. new trees are not looked after properly     D. all the above

3.Land becomes desert after all trees are cut down because____________．

A. roots of trees break up the soil              B. there are too many rainfalls

C. there are no larger trees to keep rain and protect the top-soil   D. strong winds bring a lot of sand

4.The country mentioned in the passage suffered from floods and starvation  because________.

A. it set up an empire             B. the empire fell to pieces

C. it built too many warships       D. it lost its trees

5.Which title best fits the passage?

A. Trees and Man               B. How Trees Prevent Droughts and Floods
