For as long as we've known about it, humans have searched for a cure for cancer. Across the world, countless amounts of time and money have been spend on researching a way to stop the terrible disease.

    But now, it seems like the answer could have been inside our own bodies the whole time.

    Recently, the Food and Drug Administration (FDA) in the US, a government agency that's responsible for healthcare, approved a new form of gene therapy that could mean the end of a certain type of cancer.

    The therapy allows scientists to 'train” the immune cells of sick patients to fight leukemia – a blood cancer that mostly affects young people.

    The exciting new treatment works by removing healthy immune cells from the patient, known as T-cells, which are then altered to be able to “hunt down” cancer cells.

    The cells are then put back into the patient, before they begin to get rid of the patient's leukemia over time, similar to how the body fights off other illnesses.

    'this is truly an exciting new day for cancer patients,” Louis J. DeGennaro, president of the Leukemia and Lymphoma Society, said in a news release. Up until now, a drawn-out （持续很久时间的）and painful bone marrow transplant was the only option for many leukemia patients.

    In this procedure, healthy blood cells are taken from a donor and placed into the sick patient, who also has to go through chemotherapy to allow their body to adjust to the new cells.

    But with a recovery rate of around 83 percent–according to a news release published by the FDA–it's hoped that the days of painful trips to the hospital, or even death, are over for leukemia sufferers.

    “We're entering a new frontier in medical innovation with the ability to reprogram a patient's own cells to attack a deadly cancer,” FDA commissioner Scott Gottlieb said in the release.

    “New technologies such as gene and cell therapies hold the potential to transform medicine and... our ability to treat and even cure many intractable（难治的） illnesses.”

阅读下列短文，从每题所给的四个选项 （A 、B 、C  和 D ）中，选出最佳选项。

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were on holiday." I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holidays" is said "vacaciones". So they did not go to house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to houses where the sign said "NO VACANCIES", because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means "fun". In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, Thank you".

    Because someone else expects it from you.

    Perhaps you come from a family where everyone goes to college. Or maybe, you're the kid that everyone is proud to believe will be the first to get there{#blank#}3{#/blank#} It's become so much a part of the air you breathe that you've never stopped to consider whether you want to go or whether you're ready to go.

    It's been tough to find even a summer job. You don't have an alternative plan. Everyone else is doing it(see above). You think you might as well go to school. That is the lamest(无说服力的) of reasons to spend $20,000 or more in the next year.

    Because you are afraid you'll regret it if you don't go.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

Sustainability(可持续性）

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    The U. S. Thanksgiving holiday is symbolized (象征) by its traditional food-roast turkey. But turkey is certainly not from Turkey. In fact, its English name is based on one big mistake. We could say it is a case of mistaken identity. The word "Turkey" has meant "the land of the Turks" since ancient times. In the mid-1500s, the word "turkey" was first used to refer to the bird in the English language.

    The misunderstanding over the word happened because of two similar-looking kinds of birds.

    There is an African bird called the guinea fowl(珍珠鸡). It has dark feathers with white spots and a patch of brown on the back of its neck. Traders brought the guinea fowl to Europe through North Africa. This foreign bird came to Europe through Turkish lands. So, the English thought the bird as a "Turkish chicken".

    When Europeans came to North America, they saw a bird that looked like the guinea fowl. This bird was native to the North American continent. But they thought that it was the guinea fowl, which at that time, was called the "turkey cock", so they gave it the same name.

    Hundreds of years later, we continue to call this North American bird "turkey", even though it has no connection at all with the country Turkey, or even with Europe.

    But English is not the only language with interesting names for this North American bird.

    The Turkish call turkey "hindi", the Turkish name for India. The reference(涉及)to India probably conies from the old wrong idea that the New World was in Eastern Asia.

    The French call it "dinde", a name that also connects the bird to India. "Dinde" means "from India" in the French language. "Turkey" has similar names in several other languages.

For Adam Johnson, a potter from Brighton, the interest stirs (萌动) each spring. "It grabs a hold of me," he said. "I just get the desire to dig." Together with his shovel (铲), he is part of a larger movement. Around the world people are discovering the joys of an ancient practice: the digging of holes. TikTok videos of people digging purely for fun have been viewed millions of times. Instagram accounts devoted to the pastime have many followings.

Charlie Mone, a student at St Andrews University, was changed while digging on the beach in Gran Canaria last year. When he returned home, he founded the university's first hole-digging society. "I didn't think it would go anywhere," he said. Dozens of diggers regularly attend its events on East Sands Beach on the east coast of Scotland and the society's Facebook page has more than 300 followers.

Mone believes that that much of the appeal lies in the friendship working on a shared project in the sea air. "It's struck a chord (共鸣) with people," he said. "There's something therapeutic to just switching your brain off and digging a hole." At the end of each 1 session, the holes are filled in to prevent accidents.

Back in Brighton, Johnson, 38, is more of a lonely digger. "I have often started digging without an actual plan," he said. "Once I took out an unruly bramble (荆棘) and found some rock so I dug that out, then carried on a bit until I was in a good general digging rhythm. A few hours later my partner asked if I was coming in for dinner-the bramble had come out at breakfast and I found myself in a six-foot hole. The hole would become a sunken hot tub, but the digging would have been worthwhile anyway, he suggests. "There's something basic about it. And you find all kinds of buried treasure from people who had the garden before you. There's something magical about digging."
