1 . Taste memory is a kind of interesting memory. It is not only the memory of the smell itself, but also the associative memory of the things related to the smell and the emotional memory related to the judgment of the likes and dislikes of the smell. In short, when we smell a familiar smell, our first reaction is to search for the possible source of the smell in our memory - a certain kind of food? Some kind of perfume? Someone? Some place? Even if we smell a strange smell, we will subconsciously look for the smell similar to the smell in our memory.
The particularity of taste is also closely related to our survival instinct - because taste is often associated with food. It is an important survival skill to judge the food's edibility by smell. I have been experimenting with taste aversion(厌恶) memory for a period of time - a taste that has never been encountered and cannot be identified as safe. If there are adverse physiological reactions after eating, I will instinctively avoid this taste the next time I encounter it. This kind of phenomenon will be restrained to a certain extent when it comes to the familiar taste of safety, which is called "potential inhibition", that is, the degree of aversion will be reduced. However, if a person is familiar with the safe taste and has a very serious reaction, this taste will be associated with painful memory, then even if he knows that the taste is safe, he will also involuntarily avoid the food or affect his appetite. This fully shows that taste is not a single memory, but mixed with a large number of other memories.
"People's memory of smell will never be forgotten" - I don't know the origin of this proposition, and it's also too absolute to say that it will never be forgotten - in fact, many diseases lead to people's inability to smell smell, let alone their memory of smell. However, due to the particularity of taste, different taste can not only cause active memory, but also cause a variety of subconscious memory, and also bring a variety of physiological reactions in the body. Therefore, compared with other kinds of memory, it is not easy to forget, which is more reasonable.

2 . 
News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.
Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?
To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.
Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs
Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.

| A．They read news without expressions. | B．They looked like a human being |
| C．They could interview sports stars | D．They could interact with audience. |
| A．This technology is very perfect so far |
| B．This technology is quite popular now |
| C．This technology remains at the theoretical stage |
| D．This technology is far from mature. |
| A．human news anchors should learn from AT anchors to save their jobs |
| B．Al anchors perform much better than human news anchors at present |
| C．Al news anchors won 't replace human news anchors in the near future |
| D．Xin Xiaomeng s expressions vary so naturally that they are true to life |
