21、Millions of youngsters across Europe could suffer permanent hearing loss if they listen to MP3 players at too high a volume for more than five hours a week, EU scientists warned Monday.
The scientists’ study, requested by the European Commission, argued against the concept of “leisure noise,” saying children and teenagers should be protected from increasingly high sound levels. “There has been increasing concern about exposure from the new generation of personal music players which can reproduce sounds at very high volumes without loss of quality,” the Commission, the EU’s executive department, said in a statement.
Risk for hearing damage depends on sound level and exposure time. However, more and more young people have been exposed to the significant threat that leisure noise posed(造成) to hearing in the past decade. Commission experts estimate that between 50 and 100 million people listen to portable (便携式的) music players on a daily basis. If they listened for only five hours a week at more than 89 decibels (分贝), they would already go beyond EU limits for noise allowed in the workplace, they said. But if they listened for longer periods, they would risk permanent hearing loss after five years.
The scientists calculated the number of people in that risk category at between 5 and 10 percent of listeners, meaning up to 10 million people in the European Union. Sales of personal music players have increased in EU countries in recent years, particularly of MP3 players. Commission experts estimate unit sales between 184 and 246 million for all portable audio devices just over the last four years, of which MP3 players range between 124 and 165 million.
Loud mobile phones also came under fire. “I am concerned that so many young people who are frequent users of personal music players and mobile phones at high volume levels, may be unknowingly damaging their hearing,” said Meglena Kuneva, the EU’s consumer affairs official in her statement.

22、 Sharp drops in temperatures, strong winds howling...A cold snap (寒流) has struck many parts of China.
The National Meteorological Centre ( NMC) (国家气象中心) issued an orange alert on Dec. 28, as a cold air mass swept across the country from north to south. This is the first orange warning since 2016, which is the highest in the three-tier (三级的) ranking, followed by yellow and blue.
On Dec. 27, the temperature in the Greater Hinggan Mountains of Heilongjiang province fell to-44. 5℃, the lowest since winter began, the region's meteorological service said.
According to Sun Jun, the chief forecaster from the NMC, this round of the cold wave is tougher than the same period in normal years. Temperatures in more than 25 cities could reach record lows. Even in Hunan and Jiangxi provinces, temperatures have reached subzero.
Since early December, China has reported power squeezes in the provinces of Hunan, Jiangxi and Zhejiang. Street lamps in several cities have not been on. Elevators in some office buildings haven't worked. The central air conditioning in malls，libraries and government buildings has been off for several days, Xinhua reported.
According to the National Development of Reform Commission ( NDRC) ( 国家发展改革委员会)，the power cuts in these provinces are a result of the dramatic increase of demand for electricity fueled by the high demand of industries that have now recovered and are keen to make up for the lost time earlier in the year and the low temperatures.
Meanwhile, domestic needs for electricity also surged. For instance, in Hunan, low temperatures came at least one month earlier than usual in the province this year. Millions of people started using space heaters to deal with the cold weather.
In order to help people get through these conditions, China is increasing its supply of natural gas and coal to ensure its power generation and heating needs，according to the NDRC. Major coal producers in the provinces of Shanxi and Shaanxi have been instructed. to boost production capacity and coal imports. The NDRC has ordered power plants to have coal reserves for at least 18 days. It would also guarantee the power support to regions in Hunan and Jiangxi, which are short of the supply of coal.
【1】What does the underlined word in Paragraph 5 probably mean?
A．Shortage.
B．Abundance.
C．Waste.

23、What it does
The self-cleaning door handle is combining with advanced photocatalytic ( 光 催 化 ) and blacklight technology. A light source activates the door’s handle coating, telling it to start cleaning. It can minimize the risk of infection by contact and improve the cleanliness of a space.
How it works
The working principle of the product is that a thin advanced photocatalytic coating can effectively decompose bacteria ( 细 菌 ) on the surface of a substance. A consistent UV light source—inside a transparent glass door handle—is required to activate the door’s handle coating on the outer surface for disinfection, so a generator is used to provide electricity to light up a UV LED lamp by the motion of an opening and closing door. Then, the door handle can clean by itself.
Design process
We made the first version by using stainless steel. However, it caused the door handle to be heavier. Then, we tried aluminum, which made it light and easy to fix. We also improved the generator output which effectively turned energy from door movement into a light source.
How it is different
Our innovative design is simple, effective, and attractive. It has an elegant smooth shape, and its minimalist appearance stands out in today’s world of inventions. Nowadays, people use chemical cleaning materials to clean up public areas but it harms the human body. Our design can be used for a long time and is effective. It can self-clean after each use. In the door lock and door handle market, it is a unique design because there are no similar products.
Future plans
In the future, we will commercialize the product and hope that it can compete on the market with similar products. We are going to connect with public properties, for example, shopping malls, hotels, hospitals and public restrooms, where the risk of spreading infection is higher.
Awards
In addition to winning the James Dyson Award, it has also received the Gold Award, and in 2016, it was featured in the 44th International Geneva Inventions Exhibition.
【1】How does the self-cleaning door handle function?
A．It controls the door movement automatically.
B．It minimizes the risk of infection by less contact.
C．Chemical cleaning materials are used to clean it up.
D．The light source tells the door handle coating to clean itself.
【2】Compared with the first version of the product, the present one is ______.
A．safer and cheaper
B．cleaner and easier
C．less heavy and more effective
D．more attractive and expensive
【3】What do we know about the new invention according to the passage?
A．It has been widely used in public areas.
B．It has received recognition for its innovation.
C．It is quite competitive among similar products.
D．It will replace traditional chemical cleaning materials.
24、Three Modern Services
When you're working a full-time job, studying or on the hunt for work, life can feel exhausting. The good news is that modern technology has made life easier in many ways, and with the following services, you'll find you have more time and energy for the things that matter.
Meal kit delivery services
Meal kit delivery services are one of the most underestimated innovations of the 21st century. How they work is simple. At the beginning you choose how many people need to eat in your household. Then, what your dietary requirements are, and any other preferences. Finally, you get to choose which meal kits will be delivered to your door.
No matter your diet, you can have an appropriate meal kit delivered. For example, check out these low carb meal delivery options. The kit comes complete with all the ingredients you need, already prepared. All you have to do is to follow the simple recipe to put them together and pop your meal in the oven.
With meal kit delivery, you don’t have to worry about cooking or spending money on takeout. Your trips to the grocery store will become easier and you'll waste less money and food.
Taskrabbit
One of the most frustrating aspects of having a place you call your own is that you have to take care of the maintenance(维修). Even if you are renting, there are certain tasks that your landlord will expect you to see to, whether a leaky tap or a problematic electrical appliance.
For this, Taskrabbit connects you with freelancers who are willing to take on just about any task for you. You can hire someone to take care of your leaky tap rather than spending your own time and energy doing it. You're giving someone work while enjoying your time off.
