[Unit 7] Directions: Choose the statement that best summarizes the main idea of Text A in Unit 7 Materials Science.
[Unit 8]Directions: Choose the statement that best summarises the theme of Text A of Unit 8.
[Unit 7] Directions: Please read the following passage in which there are five underlined parts. Determine if the underlined parts are appropriately and academically written. If not, please decide how to improve them by choosing the best answer.As illustrated in Figure 7a, the resistance variation ration linearly increased with the increasing strain under stretching. The device performance was tested at 0-150% strain and cycled for 10 times, 1exhibited the good electrical stability of PAAm/Casein hydrogels (Figure 7b). As depicted in Figure S1, the 2 resulted hydrogel sensor could endure dynamic deformation at 20% strain for 100 cycles without any signal degradation. Moreover, the hydrogel sensor maintained the sensitivity after 3 placed in the air for a period of time. When the 4 applied strain was at 100%, the hydrogel sensors could still immediately respond in the case of water loss. At the same time, this resistance change process of hydrogel could also be identified and recorded by the smartphone (Figure 7c, d), which greatly facilitated the development of real-time 5 monitoring hydrogel wearable devices.
[Unit 8]Directions: Read the following text and complete it by filling the blanks with the best expressions.Despite the potential benefits of social networking sites, such as maintaining contact with physically distant friends, sharing information, and 1 ________ (Ellison, Steinfield, & Lampe, 2007), there are well-documented adverse effects of social media use on psychological well-being. Research over several decades has shown that women who are exposed to images of idealized bodies 2 ________ the thin ideal and strive for an unrealistic standard of beauty, which can result in feelings of shame, body dissatisfaction, and low mood when they cannot achieve the same body type (Tiggemann & Slater, 2013). Thin ideal 3 ________ is characterized by images of impossibly thin and attractive female beauty that are circulated by the mass media as the standard of Western beauty (Hargreaves & Tiggemann, 2003). Often these images depict women with unattainable proportions, flawless skin, thin waists, long and slender legs, and well-developed breasts (Groesz, Levine, & Murnen, 2002). 4 ________ , first demonstrated in traditional forms of media like magazines and television, have now been demonstrated in social media, which have 5 ________ quickly and recently become the most common way that young women are exposed to images of thin ideal bodies (Mills, Shannon, & Hogue, 2017).
