1 . With the availability of easy-to-use at-home kits, DNA testing for dogs has become increasingly popular among dog owners in recent years. It can provide invaluable insights into a dog’s breed, health risks, and even behaviors.
DNA testing typically works by analyzing the genetic material found in a sample of cells taken from the inside of your dog’s cheek. This sample is then compared to a database of known breeds and genetic markers associated with certain traits or health conditions.
The first step in obtaining a DNA test kit is selecting which type you want. Most companies offer several different types of tests that vary in cost and complexity. For instance, some tests just analyze your dog’s breed composition, while others can assess additional genetic markers associated with certain diseases or behaviors.
Then it’s time to collect your dog’s sample using the provided swab (拭子) kit or saliva-collection tube included with most kits. The swab should be gently rubbed inside your pet’s cheek according to the kit’s directions before being placed into the collection container provided by the company. After collecting the sample, it should be mailed back to the laboratory for processing according to instructions given by the company providing the service. Once received by the lab, it typically takes 1-2 weeks for results to be processed and sent back via email or mail. Results will vary depending on which type of test was purchased, but they generally include detailed information about your pet’s breed composition as well as any potential health risks or behavioral traits associated with their genetics that could affect their overall well-being and quality of life.
If you’re looking for an easy way to learn more about your pup’s background without spending too much money, then DNA testing might just be right up your alley.

2 . A rare 765-year-old gold coin found on farm land in Devon in south-west England is expected to sell for up to half a million pounds at auction. It is believed that the coin was made more than 750 years ago, during the rule of the English King Henry III. It is one of only eight known to exist.
Featuring a picture of King Henry III on one side and a cross and roses on the other, the coin is around 2.5 centimetres across. It was made with gold that came from north Africa. It was found in September last year by a detectorist (someone who looks for items buried underground using a metal detector) in Hemyock village. The detectorist had no idea how rare the coin was until he posted a photo of it on social media, where it was spotted by a history expert.
The finder, who doesn’t want to be named, was told to take the coin to the British Museum, where it was confirmed that the coin was very rare. According to the law, the finder is allowed to keep it because it’s a single coin and not part of a bigger haul but he has decided to sell it. He told the BBC, “The coin was found in an unappealing field and could quite easily have never been recovered. Now it is protected for future generations to enjoy.”
The coin is especially valuable because it was one of England’s first gold coins. The country’s coins were made of silver until King Henry III, who ruled from 1216 until his death in 1272, introduced gold ones with his picture on them.
Professor David Carpenter at King’s College London, has traced the coin back to a man called John de Hidon, who was the lord of Hemyock Manor. Carpenter thinks the coin may have fallen out of someone’s pocket—either de Hidon himself or one of his staff.
The correct order of the events that happened is____________.
①The value of the coin was confirmed.
②A coin was unearthed in the field.
③The coin was on display at the British Museum.
④The coin was intended for sale.
⑤The coin caught the attention of a history expert.

3 . World War II had started, and British ships were always watching for German submarines called U-boats. The ship Ben Lomond had left Cape Town, South Africa, with a crew of 55, including a young officer named Poon Lim. On November 23, 1942, Ben Lomond was attacked by a U-boat. Within minutes the ship was sinking. Poon Lim grabbed a life jacket and leaped over the side. He swam rapidly away from the ship in case it exploded. Sure enough, it let out a large boom and sank beneath the waves.
Poon Lim struggled in the water for two hours. Then he saw an empty raft (筏), swam to it, and climbed aboard. He found a few cans of crackers, a water jug, some flares, and a flashlight, which could be enough supplies for about a month. Day after day Poon Lim had his few crackers and a couple of sips of water. He searched the horizon for ships. Twice he leaped up to shout and wave when he saw help coming. Once he saw a freight ship. It passed him. At a later time, he saw a United States Navy plane. It flew low over the raft but then disappeared. Still later a U-boat spotted him but for some reason left him alone. Poon Lim knew he needed to stay strong. He couldn’t get much exercise on an eight-foot-square raft, but he could swim circling the raft, a couple of times a day. Soon his food and water ran low. He knew that drinking seawater would make him sick, so he tore off the canvas cover on his life jacket and set it out to catch rainwater. Then he took apart the flashlight and used a wire inside to make a fishhook.
For months Poon Lim drifted, catching fish and sometimes birds. One time he even caught a shark. Finally, after 133 days, he saw a boat. Three sailors in a small sailboat picked him up and took him to Belém, a city on the coast of Brazil. Poon Lim had crossed the Atlantic Ocean. No one ever had survived longer on a raft at sea. Poon Lim received many honors, including Britain’s highest award. A booklet of his survival methods was put into every British life raft. But when Poon was interviewed, he said “I hope no one will ever have to break that record.”
Which is the correct order of the events?
a. Poon received many honors. b. Poon was short of food and water.
c. Poon managed to go on board a raft. d. Poon was picked up and taken to Belém.
e. Poon swam helplessly in a life jacket for hours.

4 . A schoolgirl saved her father’s life by kicking him in the chest after he suffered a serious allergic (过敏的) reaction which stopped his heart.Izzy, nine, restarted father Colm’s heart by stamping (踩) on his chest after he fell down at home and stopped breathing.Izzy’s mother, Debbie, immediately called 999 but Izzy knew doctors would never arrive in time to save her father, so decided to use CPR.However, she quickly discovered her arms weren’t strong enough, so she stamped on her father’s chest instead.Debbie then took over with some more conventional chest compressions (按压) until the ambulance arrived.Izzy, who has been given a bravery award by her school, said, “I just kicked him really hard. My mum taught me CPR but I knew I wasn’t strong enough to use hands. I was quite scared. The doctor said I might as well be a doctor or a nurse. My mum said that Dad was going to hospital with a big footprint on his chest.”“She’s a little star，” said Debbie, “I was really upset but Izzy just took over. I just can’t believe what she did. I really think all children should be taught first aid. Izzy did CPR then the doctor turned up. Colm had to have more treatment on the way to the hospital and we’ve got to see an expert.”Truck driver Colm, 35, suffered a mystery allergic reaction on Saturday and was taken to hospital, but was sent home only for it to happen again the next day. The second attack was so serious that his airway swelled, preventing him from breathing, his blood pressure dropped suddenly, and his heart stopped for a moment.He has now made a full recovery from his suffering.
What’s the right order of the events?
①Izzy kicked Colm. ②Debbie called 999.③Izzy learned CPR. ④Colm’s heart stopped.

5 . In many countries of the world, people can confidently tell you the meaning of their town or city, but most people who live in Manchester, Oxford or Birmingham would not be able to explain what the name of their city means. The name of every British town and city, however, has a long history. Two thousand years ago, most people living in Britain were Celts........This is why there are so many place names in England which end in “-chester” or “-caster” –Manchester, for example. ..........The Romans never reached Wales or Scotland, and many place names there are Celtic.........After the Romans left Britain, it was attacked by tribes called the Anglo-Saxons who were from the area of Europe that is now Germany and Holland............Twelve hundred years ago, the Vikings came to England from Scandinavia. They traded with the Anglo-Saxons but lived in their own villages. ........Finally, in 1066, England became Norman — the Normans gave us the place name “grange”, which means farm.........
Which of the following shows the correct order of the arrival of inhabitants in Britain?
| A．The Celts –The Romans – The Vikings –The Normans –The Anglo Saxons |
| B．The Romans –The Celts –The Vikings –The Anglo Saxons–The Normans |
| C．The Celts –The Romans –The Anglo Saxons–The Vikings –The Normans |
| D．The Romans –The Anglo Saxons–The Celts –The Normans –The Vikings |
6 . The story of chocolate begins with the discovery of America in 1492. Columbus was the first European to come into contact with cacao. Columbus was struck by how much value the Indians placed on them as he did not know the beans were used by currency. It is unlikely that Columbus brought any of these beans back to Spain and it was not until about 25 years later that Cortez grasped the commercial possibilities when he found the Aztecs using the beans to make the royal drink “chocolate”.
The Spanish, in general, were not fond of the bitter drink so Cortez and his followers made it more palatable by adding cane sugar and later cinnamon and vanilla were added. Spanish monks let the secret out back home and, although the Spanish hid it from their neighbors for a hundred years, finally chocolate’s popularity grew until it was their fashionable drink at the French court and the wise choice of customers at London meeting houses.
The cacao tree is strictly a tropical plant only in hot, rainy climates. Thus, its cultivation is limited to countries not more than 20 degrees north or south of the equator (赤道). The cacao tree is very delicate and sensitive. It needs protection from the wind and requires a fair amount of shade under most conditions. This is true especially in its first two or three years of growth. A newly planted young cacao tree is often sheltered by a different type of trees. It is normal to plant food crops for shade such as bananas, plantain, coconuts or cocoyams. Rubber trees and forest trees are also used for shade. Once established, however, cacao trees can grow in full sunlight, provided there are fertile soil conditions and intensive farming. With cutting and careful cultivation, the trees of strains will begin bearing fruit in the fifth year. With extreme care, some strains can be stimulated to produce good crops in the third and fourth year.
The process of turning cacao into chocolate hasn’t changed much since the Swiss made the major breakthroughs in the process in the late 1800s. First the beans go through a process of fermentation ( 发酵 ) and drying. They are then sorted by hand before cleaning and then roasting. Winnowing ( 风 扬 ) follows which removes the hard outer layers and leaves what is as the “grains”. A crushing and heating process known as Hunte’s Process is then used to remove nearly half of the cocoa butter from the nibs. This makes unsweetened chocolate. Basic eating chocolate is made from a mixture of the unsweetened chocolate with some of the cocoa butter along with other ingredients such as sugar and vanilla. The resulting product is then “purified” and this purifying gives chocolate the silky texture that we know so well. The finished result is then shaped, cooled, packaged by machine, distributed, sold and of course, eaten!

| B．Because he didn’t know how to turn cacao bean into chocolate. |
| C．Because he was not aware of the monetary value of cacao bean then. |
| D．Because Spaniards then didn’t favour the chocolate that the Aztecs originally drank. |
| A．affordable | B．agreeable | C．patent | D．portable |
| A．Cacao trees need a lot of looking after to be used commercially. |
| B．Cacao trees require hot, rainy climates and adequate sunlight. |
| C．Cacao trees won’t produce fruit until the fifth year. |
| D．Cacao trees can grow well in all continents. |
① The chocolate is reheated to melt it, put into patterns and then cooled to make its final shapes.
② The beans are harvested on the farm.
③ Some cocoa butter is then obtained using Hunte’s Process to make cooking chocolate.
④ The cooking chocolate is then mixed with other ingredients to make the various types of eating chocolate available today.
⑤ The beans are winnowed after fermentation and drying and these two processes produce the grains.

7 . By the mid-1920s, Pablo Picasso, one of the most influential artists of the 20th century. had been one of the most celebrated men .In 1957, when Pablo Picasso was in his seventh decade, he joked that x-ray technology might one day reveal a lost work underneath one of his early paintings. Today, that prediction became reality although the technology involved goes far beyond x-rays.
Using hyper-modern tools to peer into one of his Blue Period paintings, researchers have not only shown a hidden piece of art history in astonishing new detail, they have revealed a striking amount of insight into Picasso's creative process and style.
The investigation focused on"La Miséreuse accroupie, "or" Crouching Woman, "painted in 1902 and currently owned by the Art Gallery. The painting, an oil on canvas (画布) piece drawing a crouching (蜷坐的) woman who wears a long coat, shows Picasso’s typical Blue Period colors: grey, green, blue and white. It shows that the innovative modernist was inspired by the lines of an underlying landscape painted by an unknown artist.
The analysis also exposes several changes to the woman described in the painting,many of which Picasso ultimately abandoned. Researchers released their findings on Saturday’s press conference of the American Association for the Advancement of Science in Austin, Texas. “We think now it's a landscape painted by someone enrolled at the fine arts academy in Barcelona, someone in Picasso’s orbit but not in his close circle, ”says Kenneth Brummel, assistant curator of modern art for the Art Gallery of Ontario.
As to why Picasso would have “recycled” another artist’s canvas(油画布), reasons could range from economic necessity, as a young artist still establishing himself, to deep inspiration driven by the lines of the image already laid down there. Picasso often re-used canvases for this reason."
“He didn't shave off the canvas or put a preparatory layer over it,” Brummel says.“ Picasso saw this landscape, found inspiration, and decided he was going to paint it immediately."
1. According to the text ,the most likely process of Picasso's painting?①Picasso reused another artist's canvas.
②Inspired by a landscape painting, Picasso decided to paint one too.
