Restoring touch (P6)

山东省烟台第二中学 赵霞
Lead in
What are they? What are they used for?


They are prostheses used for people who lose an arm or a leg.

What kind of impact do you think the disability will have on those people?


They can’t have the same life as normal people.

With the use of a prosthetic limb, can people get their normal life back?
Not necessarily, because they can’t restore the sense of touch.

Let’s read the passage and find out whether there are more advanced products that can address this issue.

Read for the main idea
Now read the passage and figure out what it talks about. (What is the main idea?)

A group of Swedish scientists created the neuromusculoskeletal prosthesis. It allows people to experience sensations of touch in mind-controlled arm prostheses.


Read for detailed information
Read the passage again and answer the following questions.

1. Fill in the blanks and complete the basic information about the new product.


2. How does the new product work?
   The prosthesis is connected directly to a user’s nerves, muscles and skeleton. The sense of touch becomes possible by stimulating nerves that used to be connected to the biological hand before the amputation.


3. Fill in the blanks according to the passage.


4. What is the progress and significance of this new product?

The ability of the patients to discern smaller changes in the intensity of sensations has improved. The prosthesis is qualified as a clinically viable replacement for a lost arm.

intensity of sensations:感觉的强度
be qualified as: 适用于做……有做……的资格
viable replacement:可行的替代品


5. What makes restoring the sense of touch difficult?

The challenge is creating neural interfaces that can seamlessly transmit large amounts of artificially collected information to the nervous system, in a way that the user can experience sensations naturally and effortlessly.


Read for language and grammar
1. Seven years ago, a group of Swedish scientists created a new type of prostheses, which has since been tried out on three patients to see how they perform in people’s daily lives.
how引导的是宾语从句,做动词see的宾语
译文:七年前瑞典科学家发明了一种新型假肢,已经在三个病人身上进行了试验,看看它们在人们日常生活中作用如何。

非谓语动词

1. Losing an arm means losing the ability to grab as well as a sense of touch.
2. But regaining the sense of touch has been quite a challenge – until now.
3. When a patient grabs an object, for example, force sensors planted in the prosthetic thumb would measure contact and pressure.


定语从句
1. According to the study, this is the first time that people who have had an arm amputated have experienced the sense of touch using mind-controlled arm prostheses.
2. The collected information would then be transmitted to the patient’s nerves that lead to the brain.
3. The patient would then be able to “feel” the characteristics of the object being touched and perceive its pressure against the prosthetic hand, which can be important when handling delicate objects.
   
Translation

According to the study, this is the first time that people who have had an arm amputated have experienced the sense of touch using mind-controlled arm prostheses.

译文:根据这项研究,这是手臂被截肢的人第一次可以通过用意念控制的手臂假肢来体验触觉。


The patient would then be able to “feel” the characteristics of the object being touched and perceive its pressure against the prosthetic hand, which can be important when handling delicate objects – an egg, for example.

译文:通过这种方式,患者可以“感觉”被触摸物体的特点,并感知它对假肢手臂的压力,这一点在处理易碎物体时是至关重要的—比如说鸡蛋。


The challenge is creating neural interfaces that can seamlessly transmit large amounts of artificially collected information to the nervous system, in a way that the user can experience sensations naturally and effortlessly.

译文:挑战在于用一种使用者可以自然轻松地体验到感觉的方式,创造出可以将大量人工收集的信息无缝传输到神经系统的神经接口。
