Did you know people who live in different parts of China have different habits and preferences? For example, people from southern China prefer to eat vegetables, while people from north China like to eat meat. According to a new study in a journal, gene variations (基因变异) might be responsible for these differences. Researchers from China’s BGI collected genetic information from 141, 431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.
The researchers found that there are six gene frequencies that are different among people from both northern and southern China. They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities(免疫力)to illness and physical features.
A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences. Northern China is at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.
The study also found differences in the immune systems of both groups. Most people in southern China carry the gene CR1, which protects against malaria. Malaria was once quite common in southern China. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.
Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.
1.What did the new study focus on?
A.Regions. B.Vegetables.
C.Gene variations. D.Ethnic minority groups.
2.What is the main function of the gene FADS2?
A.It helps store fat. B.It helps digest meat.
C.It helps gain weight. D.It helps treat illness.
3.According to the study, most northerners ______.
A.are immune to malaria B.catch blood-borne illnesses easily
C.have no body smell D.sweat less frequently
4.How many differences did the study find related to genes?
A.Two. B.Three.
C.Four. D.Five.
In the UK, Bonfire Night or Guy Fawkes Night is celebrated on 5 November and the night skies are filled with color. It’s a special day in honor of a historic event.
In 1606 English Catholics were angry because the King of England, James I, was treating them badly. In protest (抗议), a group of men made a plan, known as the “Gunpowder Plot”, to blow up the House of Parliament in London. An huge explosion was planned for 5 November, the day the king was due to open parliament.
The group chose a man called Guy Fawkes to light the gunpowder. The plot did not succeed — the gunpowder was found before it exploded and all the men involved were arrested, beaten and executed. To celebrate his survival, King James ordered the people of England to have a bonfire on the night of 5 November.
On 5 November people remember the plot by celebrating Bonfire Night. All over Britain there are firework displays and bonfires with models of Guy Fawkes, made from clothes and filled with newspaper, which are burned on the fire. The fireworks are a reminder of the gunpowder that Guy Fawkes hid in the cellar of Parliament.
Children used to take home-made Guys onto the streets and ask for “a penny for the Guy” to collect money to buy fireworks. At the Edenbridge Display in Kent last year, a 9-meter “celebrity” Guy was burned of Wayne Rooney wearing Shrek-style ears and a Manchester United football shirt.
It’s normally quite cold in November in Britain, so on Bonfire Night people wear hats, scarves and gloves to spend the evening outside. Traditional Bonfire Night food is hot baked potatoes. There are also toffee apples and in the north of England they eat a special type of cake called parkin.
1.Why was 5 November chosen by “Gunpowder Plot”?
A.There would be a protest
B.There would be an explosion
C.James I would open parliament
D.James I would put Catholics to death
2.What does the underlined words “executed” in Paragraph 3 mean?
A.Scolded. B.Punished.
C.Injured. D.Killed.
3.What seems to attract children most on Bonfire Night?

Nine-year-old Patches the Dachshund was saved by a 3D-printed skull she received after the removal of an orange-sized tumor (肿瘤).
Patches had a small bump on her head for years. Her owner took her to see vets before ending up in the hands of Dr. Michelle Oblak.
Dr. Oblak had been researching 3D-printing uses for dogs. According to Oblak, a dog in Patches’ situation would need an expensive operation where the animal’s tumor and skull would be removed and then replaced. However, Oblak believed Patches was the ideal candidate to receive it.
Dymeck, Patches’ owner, said that she was hesitant (犹豫的), but the potential to help others convinced her. “They felt she could recover from this,” Dymeck said. “And to be part of research was a big thing for me – if they can learn something from animals to help humans, that’s important.”
The brand new method used to save Patches’ life started with a CT scan of her tumor. Then, Oblak and her team digitally removed the tumor in Patches’ skull. After that, they mapped out what the 3D-printed skull piece would look like and where it would fit on the dog. “There’s little room for error,” Oblak explained. “We’re talking less than two millimeters or else the plate wouldn’t fit.”
After everything was drawn out, Oblak sent the designs over to the 3D-printing company and just two weeks later Patches’ customized skull (定制的头骨) was ready. Then Patches went under the knife. After a four-hour operation, the dog was back to herself. Patches is now cancer-free. She has a scar on her head but it seems like a small price to pay for the life-saving operation.
“Our hope is this is something that could be more widely available on a broad scale,” Oblak said. “It went very well.”
1.What exactly is Patches?
A.A pet. B.A doctor.
C.A servant. D.A patient.
2.What was the problem with Patches?
A.She had a headache. B.Her skull was broken.
C.She suffered from a cancer. D.Her head was covered with scars.
3.Which word can best describe Dymeck？
A.Experienced. B.Responsible.
C.Unselfish. D.Talented.
4.What can we learn about the operation from the passage?
A.A small error happened. B.It cost Oblak a lot of money.
C.It was challenging and demanding. D.A CT scan mapped out the 3D skull piece.
