2 . Sleeping with a dim(昏暗的) light like a television or nightlight is enough to the raise blood sugar and heart rates of healthy people, according to a new study. Light helps our body maintain an internal clock, but artificial light at night can disturb the rest and repair that should happen during the sleep. New research suggests that even when our eyes are closed, a small amount of light can disrupt the way our bodies normally keep our blood sugar within a healthy range.

In the study published in Sciences on Monday, scientists asked 20 participants aged 19 to 36 to spend two nights in their lab. On the first night of sleep, the volunteers slept in a very dark room. For their second night of sleep, half of the group slept with streetlights through a window, and half spent their second night in a dark room.

During the trial, all participants were connected to devices that measured different markers of their sleep quality. They were each connected via a special tube, allowing researchers to collect samples without waking the individual. Researchers also recorded participants’ heart rates and brain waves.

When the volunteers awoke in the morning, the team tested their blood sugar and found that participants that slept in rooms with a dim light spent less time in deep sleep. In addition to having slightly worse blood sugar control, the group exposed to dim light had a higher heart rate on average. By comparison, those that spend two nights in the dark room had little difference in their blood sugar control. “They thought they slept well, but your brain knows that the lights are on,” says Zee, “you should clearly pay attention to the light in your bedroom. If you can’t give up your night light, keep it dim and at floor level.”

Earlier work has linked exposure to light during sleep to an increased risk of obesity (肥胖) in women. Zee recommends, “Make sure that you start dimming your lights at least an hour or two before you go to bed to prepare your environment for sleep.”

3 . Smart devices have become an everyday part of our lives. A smart refrigerator can go above and beyond simply keeping our food cool.

A smart refrigerator is any refrigerator that’s equipped with a Wi-Fi connection. It can share information about itself, be a real-time camera that lets users see what’s inside while at the supermarket, or act as a digital command center for the home. Some other things smart fridges are able to do include raising or lowering the temperature at the sound of your voice or with your phone, or helping you track the contents of your fridge so you don’t run into a milk shortage emergency.

Smart fridges can be particularly good at keeping food cool. It’s easier to adjust the temperature if it is higher than it should be because the door is left slightly open. This can make a difference in your energy bills and the quality and lifespan(寿命) of your food.

Many of the smart fridge’s features can also save you time when you’re rushing to get ready in the morning. The people who will benefit most from a smart fridge are probably those who have children who might be using the fridge while parents are at work. It’s another way you can keep an eye on what’s going on at home when you’re not there. However, prices do tend to run higher than traditional fridges.

If you already have a food organizational system that’s working very well for you, and you are cool with the way your fridge is handling your food, then a smart fridge may not be worth it. However, if the smart fridge’s features mentioned above sound like they would make your life easier, then one could be worth the extra money.

1. What can a smart refrigerator do?

A．Order food.

B．Record the contents inside.

C．Deal with emergency.

D．Share information with supermarkets.

2. Which of the following best describes the smart refrigerator?

A．Energy-saving but expensive.

B．Child-friendly but noisy.

7 . Climate change has been a long-standing issue that continuously drives scientists to find green, sustainable fuels. The universe’s most abundant element, hydrogen (氢), has drawn their attention and is now on its way to becoming the future of green fuel.

More than $150 billion worth of green hydrogen projects were announced globally in 2020, according to Reuters. Airbus, a European multinational aerospace corporation, has taken the lead in the new sustainable fuel industry. It has designed self-contained hydrogen fuel cell pods that can be attached to the underside of airplane wings, promoting the use of hydrogen fuel for long-distance flights, which aim to achieve zero emissions. The company plans to launch hydrogen-powered aircraft in 2035, according to Daily Mail.

Compared to fossil fuels, hydrogen is a much more eco-friendly fuel. When hydrogen burns, the only by-product is water. However, the traditional way to get hydrogen from natural gas or coal generates considerable carbon emissions. The greenest way is to obtain hydrogen from water using electrolysis (电解) powered by renewable energy, although this process requires so much electricity that it is quite expensive. The key to making hydrogen competitive with fossil fuels is to lower the production cost to under $1.50. This would require lowering around 50 percent of renewable power costs and 75 percent of electrolyzer costs, according to Australia’s renewable energy agency.

Also, shipping liquid hydrogen is challenging, given that needs to be chilled to -253℃ to do so. Japan’s Kawasaki Heavy Industries is set to complete the construction of the world’s first liquefied hydrogen carrier by early 2021. According to Reuters, most of the world’s big hydrogen export projects are looking to ship hydrogen in the form of liquid ammonia (氨), which can be changed to hydrogen and needs to be chilled to only -33 C.

With more and more countries aiming to cut down carbon emissions to solve the issue of global warming, green hydrogen will help decarbonizing industries that can’t be electrified hit the targets.

“We could use these circumstances, where loads of public money are going to be needed into the energy system, to jump forward towards a hydrogen economy,” said Diederik Samsom, who heads the European Commission’s climate cabinet.

1. What is the strength of the hydrogen fuel?

A．It works very efficiently.	B．It is convenient to store.
C．It is environmentally friendly.	D．It produces no by-product.

2. What is the challenge when shipping liquid hydrogen?

A．The expensive cost of shipping.	B．The required temperature.

8 . Nearly two years after the COVID-19 outbreak, China has granted approval to its first antibody combination treatment for COVID-19.

A team from Brii Biosciences, Tsinghua University, and the People’s Hospital of Shenzhen has accomplished the task in 20 months. It would usually takes 10 years. “It can reduce the rate of hospitalization and death by 80 percent,” said Zhang Linqi, leader of the research team.

The new antibody drug is immediately effective when conducted intravenously (静脉注射). Moreover, the treatment can protect people, especially those whose physical condition doesn’t allow vaccination, from becoming infected by COVID-19 for around nine to 12 months, said Zhang. How does it work? When a virus infects a cell, it relies on an important type of protein: the spike proteins on its surface. The spike proteins serve as a key to unlocking a cell. If a virus cannot enter a cell, it will be destroyed immediately. The job of our antibodies is to block the virus from entering cells. So its target is very precise. In addition, thanks to the coordination between the two antibodies, it is highly efficient and durable in controlling the virus, according to Zhang.

Lab tests suggest that the antibody combination can be effective against common COVID-19 variants, including the Alpha, Beta, Delta, Lambda and Mu. Testing with the newer Omicron strain is ongoing. The qualities of the new drug make it especially useful for high-risk groups, such as frontline medical workers and people who are not suitable for vaccination due to various possible health problems.

The new drug is expected to come to the market soon, but it’s not cheap. That’s because of limited production. Also, it typically must be administered intravenously in a hospital setting.

Noting that China has used science and technology to fight COVID-19 since the beginning of the outbreak, Zhang said: “Science is the core to solving the issue. Science has shown its power in all sectors, from medical treatment, medicine and vaccine development to prevention and control measures.”

1. What do we know about the new drug?

A．It can remain active in human bodies for 20 months.
