The logic is obvious: Green roofs can help to cool down buildings and pull some carbon dioxide from the air and feed it back into plant (1)_. But the (2)_ benefits of green roofs to busy office workers may also be substantial. Kate Lee and a group of colleagues found that (3)_ an attention-demanding task with a 40-second "microbreak" — in which one simply looks at a computerized (4)_ of a green roof — improved focus as well as subsequent performance on the task. In the research, 150 students were asked to perform a demanding task called the Sustained Attention to Response Task (SART). In the task, respondents view a (5)_ of individual numbers, between 1 and 9, on a computer screen. Each number flashes by very (6)_ and the research subject has to press a particular key as fast as possible — unless, the number is 3. In that case, subjects have to catch themselves and not respond — which is difficult to do, given the habit built up of repeatedly and quickly (7)_ the key. In the current study, students had to (8)_ the SART task not once, but twice. However, they received a 40-second "microbreak" in between the two trials. During that break, their computer screens flashed either to a digital image of a city building roof covered in (9)_, or one covered with grass and flowers. Then, they completed the remainder of the SART trial. Afterward, the students (10)_ to the green roof scene not only reported that it felt more "restorative (复原健康的)," they performed better on the task.

I) exposed Although progress has been made, equality between male and female professionals remains a critical issue. According to a (1) _ released by global recruitment specialist group Hays on Tuesday, women are less likely than their male co-workers to believe that pay equality and (2) _ opportunities exist for both genders in the workplace. Hays polled 521 professionals, 55 percent of whom were female. Only 7 percent of women aged 25 or under think there is (3) _ inequality of pay. But as they progress in their career, that number (4) _. About 29 percent of women aged between 26 and 40, and 35 percent of women aged 41 or above think there is gender inequality of pay. In general, transport and distribution, mining and (5) _, as well as professional services, drew the most negative answers among both male and female professionals (6) _ equal pay. But the (7) _ of polled men think that the situation is not that bad, as only 13 percent of them think that equally capable men and women are not paid or (8) _ equally.

This makes it difficult to see how we will see any significant advancement in this area while the majority of people in senior roles do not (10) _ it as an issue," said Christine Wright, managing director of Hays.
