[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).

[Unit 7] Directions: Please fill in the blanks with the correct words.The energy consumption and current efficiency at different voltages were investigated and calculated based on the variation of voltage and current in the first 30 min. The curves for the current efficiency and energy consumption at different applied voltages are (1) in Figure 1. Both energy consumption and current efficiency (2) with voltage. When the applied voltage was 15 V, the energy consumption showed a (3) increase compared with that at a voltage of 10 V. (4) , the energy consumption (5) increased to 1.07W·h/g at a voltage of 20 V. Based on these results, and knowing that an overload voltage might lead to water electrolysis and scaling on the membrane surface, 15 V was determined to be the optimum voltage for the electrodialysis experiments.

[Unit 8]Directions: Match the word in the left-hand column (1-10) with the expression in the right-hand column (A-J).
