【推荐3】A hearing aid is a small electronic device you wear in or behind your ear to make sounds louder. A hearing aid has three basic parts: a microphone, an amplifier and a speaker. The hearing aid receives sound through a microphone, which changes the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and sends them to the ear through a speaker. There are three styles of hearing aids.

·Behind-the-ear (BTE) aids are used by people of all ages. “Mini” BTE is a new kind. These small and open-fit aids fit behind the ear completely, with a narrow tube into the ear canal, enabling the canal to remain open. Thus, some people prefer it because their own voice does not sound “plugged up”.

·In-the-ear (ITE) aids fit completely inside the outer ear. Some ITE aids may have added features, such as a telecoil that allows users to receive sound through the circuitry of the hearing aid, rather than through its microphone.

•Canal aids fit into the ear canal and are available in two styles. In-the-canal (ITC) aids are made to fit the size and shape of the ear canal. Completely-in-canal ( CIC) aids are hidden in the ear canal.

The hearing aid that will work best for you depends on your hearing needs and lifestyle. Price is also a key consideration. However, just because one hearing aid is more expensive than another does not necessarily mean that it will better suit your needs. Other features to consider include parts or services covered by the guarantee, estimated costs for repair, and the hearing aid company’s reputation for quality and service.

The idea of a basic income involves giving citizens a fixed amount of money for nothing. Finland ran an experiment with two thousand unemployed people through 2017 and 2018, and its Labour Institute for Economic Research (Kela) started reporting on the results in February.

In its first report, Kela said the basic income didn't much affect the amount of work that the subjects picked up during the experiment, but it did make them feel more confident about their ability to find work.

On Thursday, Kela released further results, noting that survey respondents felt less stressed about their finances and more in control of their lives but also that the basic income appeared to change the way they felt about society.

Here’s where it gets interesting for policymakers. According to Kela, “Respondents who received a basic income had more trust in other people and in public institutions politicians, political parties, police and the courts than members of the control group.”

The idea of basic income has gained attention in recent years, largely due to fears over automation’s effect on employment. In the US, a universal basic income is one of the core proposals of 2020 presidential candidate Andrew Yang, who insisted that it would not make people lazier. The Finnish results seem to back him up on that. In India, the Congress party is promising basic income for 250 million of India’s poorest people. The UK’s Labour Party is also warming to the idea, and plans to add a basic income to its next campaign.

Nearly 500 fresh products will no longer have “best before” dates printed on them. This move is designed to reduce food waste by encouraging shoppers to use their own judgement as to whether a product is still good to eat, rather than relying on a printed date.

Marija Rompani, director of Waitrose&Partners, points out 70% of all food wasted in the U. K. happens at home. U. K. households throw away 4. 5 million tons of eatable food every year, meaning that all the energy and resources used in food production are wasted. He says this move will save money at a time of rising food costs and increasing financial pressures. By using up existing fresh food in our homes, we can also save on our weekly household food shopping, which is becoming an increasingly pressing concern for many.

Waitrose-Partners is not the only supermarket to make such changes in recent years. Another British chain, Morrison’s, made headlines in January for removing “use by” dates on milk, urging customers to do a test with their noses to determine whether or not the milk is still good to drink. Tesco removed “best before” dates on more than 100 fresh food products in 2018, and MarksSpencer did the same this summer for over 300 products after a successful smaller trial.

“Best before” typically refers to the date before which an item will have best taste and texture. Passing the date does not mean it goes bad — just that it’s less good. “Use by” refers to safety and will still be applied to Waitrose & Partners products where there’s a risk of food poisoning if consumed after the date printed on the packaging. There are exceptions if the item has been frozen ahead o£ its “use by” date.

It should be said that this judgment is not scientific. We should objectively understand the position of pork price in the overall price and its possible linkage effect.

At present, the main problem faced by the pork price is the lack of pork production capacity, which has nothing to do with inflation and will not lead to inflation. The rise of pork price only affects the upstream and downstream of pig industry and other related products such as meat, but has limited impact on the overall price. At present, China's agricultural product supply is sufficient; the production capacity of consumer goods is constantly improving; the service supply is more diversified, and the monetary policy remains stable, which provides a solid foundation for the stable operation of prices.

Keeping prices, especially the prices of important people's livelihood commodities, basically stable is related to the basic life of the people. In the face of rising pork prices, the state's policy of ensuring supply and stabilizing prices continues to increase. From choosing the right opportunity to put frozen meat reserve to starting the price subsidy mechanism, from rectifying the improper restriction and prohibition measures to protecting the land for pig farms, from special financial support to financial insurance escort, all departments are taking measures. With the gradual effectiveness of the measures, the price of pork will be stable in the future. It is worth noting that the data of the Ministry of Commerce on September 10th shows that the increase of pork wholesale price has fallen back from the previous week (from September 2nd to 8th).
