1 . Next-generation fitness equipment and robots help you cook dinner. Those are a few of the countless new products expected to be shown next week at CES, the annual tech conference that typically sets the tone for the biggest trends of the year. Home automation(自动化), health and 5G will once again be hot topics, but many companies will also introduce pandemic-specific features to reflect our increased time at home.
Each year, reporters, exhibitors and investors typically explore Las Vegas showrooms filled with giant TVs, smart cars and robots, but CES will be online only for the first time in its 54-year history due to Covid-19.
The Consumer Technology Association, the nonprofit behind the four-day event starting Monday, said 1,800 exhibitors from around the world will fill its "digital venue" this year—a number that's down significantly from 4,000 in-person exhibitors last year. The move will allow tech companies from countries which have never attended before to take part in the online exhibition, but could also make it harder for smaller companies to get noticed without a physical showroom.
Registered attendees will be able to stream and re-watch keynotes from companies such as Verizon (VZ) and General Motors (GM), tune in to breakout sessions -- about how, for example, technology is playing a role in vaccine deployment(疫苗的应用)—and search through a registry of exhibitors to watch new product presentations.
It'll lack some of the signature ingredients(因素)of the trade show, such as hands-on time with the latest small machines and networking. But the technology that makes our lives more connected and convenient will still gain popularity.

2 . Two vaccines(疫苗)developed by a Maryland company are showing promise in the fight against malaria(疟疾). One vaccine was 100 percent effective in preventing the deadly disease malaria.
Malaria is a disease caused by parasites(寄生虫)and carried by mosquitoes. Parasites are organisms that live on or in an organism of another species and feed off it or get protection from it. Mosquitoes spread the disease to people by biting on their skin. The World Health Organization says there are 214 million cases of malaria each year. And the deadly disease kills over 400,000 people a year worldwide. People who have malaria often have a fever, chills, and flu-like illness. Serious complications happen, including death, when the disease is left untreated.
The new vaccines work by preparing the immune system to fight the disease. Researchers do this by introducing live, but weakened, young parasites called sporozoites. They are injected into the body by infected mosquitoes. Both vaccines target Plasmodium Falciparum(恶性疟原虫),which is the most common and deadly form of the disease.
One successful trail was carried out in Germany. Different amounts of the vaccine were injected into 27 healthy people who volunteered for the study. Another group of 15 was given a placebo, which is a substance given to a patient like a drug, but t has no physical effect on the person. Eight to 10 weeks after the last vaccine amount, both groups were then exposed to the parasites that carried the malaria.
Stephen Hoffman is chief executive and scientific officer of Sanaria. He says the researchers were surprised by the results from nine of the people who received the highest vaccine amount. “We got 100% protection against malaria at ten weeks after the last amount of the vaccine. That is really beginning to look like something quite extraordinary and that's never been done before.”

3 . If there were an app on your phone that could improve your memory, would you try it? Who wouldn't want a better memory? After all, our memory can be easily damaged by diseases, injuries, mental health conditions and, most particularly for all of us, aging.
Nowadays, there are a large number of apps that provide memory training on our phones. Can they help you remember to take medicine, do better on a school exam, remember the name of the person whom you met yesterday? Some scientists question whether this is possible. Undoubtedly, many of the brain training companies today exaggerate the potential benefits of using their apps.
Scientists have provided evidence that brain training does not benefit everyone in the same way. It is suggested that little consideration has been given to who would benefit most from those brain training apps. Will it only be those who have some form of memory impairment(缺陷),or can it also help those eager for self-improvement even though they are already functioning very well?
To overcome these limitations, our team has started a new study aiming to find 30,000 volunteers to help us determine which form of training may be best for individuals. Our goal is to avoid a one — size — fits — all approach. Instead of focusing on the simple question of whether brain training works, we are looking to engage the whole population in a new challenge to test for whom brain training works, and under which conditions.
1. What can affect our memory in particular?A.Getting ill. | B.Getting old. | C.Being upset. | D.Being injured. |
A.Supportive. | B.Doubtful. | C.Neutral. | D.Indifferent. |

4 . It is a big job to take away a city’s rubbish. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have mountains of rubbish.
In some cities the rubbish is collected and taken outside of the city to a dump. Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathrooms and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this was an old rubbish dump before.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly changes into something called humus, which looks like black earth. It is rich with kinds of things that feed plants and help to make them grow.

5 . Due to climate changes, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking (减少) ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.
In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast (绝食) during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped by 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.

6 . Researchers in Singapore found that eating mushrooms over twice per week could help prevent memory and language problems later in life.
According to the study, published in the Journal of Alzheimer’s Disease, there is a unique antioxidant (抗氧化物质) present in mushrooms that helps protect certain brain functions.
Researchers observed 663 Chinese adults aged over 60 whose diets and lifestyles were tracked from 2011 to 2017. In the study, the participants were asked how often they ate six different types of mushrooms: oyster, shiitake, white button, dried, golden and tinned. The findings showed that eating more than two shares of mushrooms per week somehow lowered the chances of mild cognitive impairment (MCi) by 50% against those who ate fewer than one share.
MCI is a condition that can make people forgetful, affect their memory and cause problems with language, attention and finding the exact position of objects in space. Changes in behavior can be not very noticeable and not serious enough to be known as dementia (痴呆).
Participants who ate more mushrooms were found to perform better in thinking and processing exams and also exhibited a faster processing speed. The advantage was reportedly more apparent in those who ate more than two shares a week or more than 300 grams.
The scientists pointed out, however, that they have yet to put up a direct link between the fungi and brain function.
The researchers also acknowledged that since this study mainly relied on self-reported information on mushroom intake and other dietary factors (因素), further studies may be required.
Still, the lead study author Lei Feng is encouraged by their findings.
“This correlation is surprising and encouraging,” Lei said.
Mushrooms are one of the richest dietary sources of ergothioneine — a matter which humans can’t make on our own.
