{#blank#}2{#/blank#} They established the first cocoa plantation and used the cocoa beans as the main ingredient in a dark，bitter drink that we would call “chocolate”. The Mayas believed that chocolate had mystical properties.{#blank#}3{#/blank#} In fact，cocoa beans were used as a form of currency that was worth its weight in gold.

    Spanish conquistador Hernando Cortez was the first European explorer to realize cocoa's commercial possibilities.{#blank#}4{#/blank#} In 1529，Cortez returned Spain and introduced chocolate—as a drink mixed with sugar，vanilla，and cinnamon—to European society.

    It caught on，especially with the nobility. As its popularity spread，people found new ways to make and use chocolate.{#blank#}5{#/blank#} Whether it is in delectable desserts or crunchy candy，people all over the world are still in love with chocolate.

A. But cocoa also had commercial value.

B. But not all the people all over the world love cocoa.

C. For centuries，the native there regarded cocoa as a gift from the gods.

D. When he arrived in the New World in 1519，he soon established his own cocoa plantation.

    Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly.{#blank#}1{#/blank#}But it can get worse and cause life-threatening symptoms (症状), such as bleeding and trouble breathing.

{#blank#}2{#/blank#}

    Ebola does not spread like colds or the flu because it does not float through the air. Ebola also doesn't spread through food or water, like some other viruses. Instead, Ebola spreads when someone touches the body fluids(液体) of a sick person.

{#blank#}3{#/blank#}

    An outbreak is when many people are getting sick with the same illness around the same time. You may have heard of a flu outbreak, which is when lots of people get sick from the same types of flu virus. When an outbreak happens because of a virus, more people could get sick because there is a lot of that virus around.

    Where did Ebola come from?

Scientists aren't sure how the first person gets Ebola at the start. {#blank#}4{#/blank#} Tropical animals in Africa believed to carry the virus include great apes, chimpanzees, gorillas, monkeys, fruit bats, porcupines, and forest antelopes.

    What do kids need to do about Ebola?

    Ebola is making many people sick in Africa, but no matter where you live, it's always a good idea to wash your hands well and often. {#blank#}5{#/blank#}

A. What is an outbreak?

B. How do people catch Ebola?

C. Why do I need to wash my hands?

D. It's very important that infected people get treatment right away.

E. Ebola symptoms can start with fever and headache, kind of like the flu.

F. But they think that people may pick up the virus by touching or eating infected animals.

G. Keeping hands clean can help protect you from common illnesses like colds and the flu.

Do you like spicy food?

    What's your opinion on spicy food? Some people cannot handle even the smallest amount of chili-red pepper-in their dinner while others can't get enough of it.

    Scientists have long been puzzled by why some people love chili while others loathe it. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chili is related to childhood experiences, and cultural influences affect our taste buds too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.

    "We have always assumed that liking drives intake-we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits with intake of chili peppers,"said Professor John Hayes from Pennsylvania State University, who led the study.

    But before you look at the study, you should first know that "spicy" is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill, something they usually get from watching action movies or riding a roller coaster.

    In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personality, for example, whether they like new experiences or tend to avoid risks. They were then given a glass of water with capsaicin, the plant chemical that makes a chili burn, mixed into it.

    By comparing the answers to the questionnaire and what participants said they felt about the spicy water, researchers found that those who tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.

    Interestingly, we used to believe that the reason some people can withstand spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise. "It's not that it doesn't burn as badly, it's that you actually learn to like the burn," Hayes explained.

    Craft (手工艺）is becoming a heritage industry — but a record of disappearing skills might just come in handy in the future.

    Mr. Lobb (of John Lobb the bootmaker) mentioned that custom clothing and shoe-making were once the norm for everyone. How come，then，today a pair of normal Lobbs would set you back over £2,000? The price has obviously gone up because of lack of competition and higher wages，but would custom clothing once again be affordable to all if the demand was there? Do we just wave goodbye to these skills，or should we fight to maintain them?

    The disposable (一次性的）culture we “enjoy” today has existed in our life for almost two generations now. We like our products to be made by either a robot or invisible，cheap hands so that we can accumulate them cheaply and frequently. The concept of “craft” is something that's now largely considered to be strange，and seems to be limited to museums and dusty, independent shops. Hobby crafts such as knitting do undergo revivals (复兴)from time to time，but I think that's because they are seen as short-lived fashionable leisure pursuits rather than a craft worthy of revivals on a commercially feasible (可行的)scale.

To drive a revival in any of these crafts, you would probably need to apply the same marketing techniques that are used to sell any other items today. The consumer must believe that they just have to have it. If they don't have it now, it will either go up in price or go out of fashion — both reasons enough in themselves for a shopper to act.

    But does it finally matter if these skills will no longer serve any practicable use in the decades to come? I don't know the answer to that，but I have long thought it would be a good idea if we “banked” these skills somehow，just as we are not attempting to do with seeds. You just never know whether we'll need them in the future. Maybe it's time to establish a worldwide network of volunteers to record，through the written words and videos，as many of these dying skills as possible. Actually, a rough look on YouTube fills me with hope that an army of willing volunteers is probably out there already and just needs someone or something to gather them together.

    Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.

    The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents' quality of life and wellbeing.

    The young adults taking part in the study were "more positive than might have been expected about moving back home—the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often slipping back easily into teenage patterns of behaviour, the study found.

    Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.

    The families featured in the study were middle-class and tended to view the achievement of adult independence for their children as a "family project". Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder.

    "However", the study says, "day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates".

    Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.

No one could have expected that slow-moving Qigong {#blank#}1{#/blank#}(become) popular among Chinese young people in the past several years. Short videos of young Chinese doing traditional fitness Qigong have flooded video websites, among {#blank#}2{#/blank#} a video of Baduanjin has been played for more than 10 million times and received over 6,000 comments on a video sharing platform {#blank#}3{#/blank#}(target) young people.
