. Deadlines are one of the biggest 1 of stress in the workplace. 2 , many are flexible: Your manager might ask you to 3 a proposal for a long-term project by Friday, but not plan to 4 it until Tuesday. Could asking for more time (when we need it) be a simple way to 5 feeling panicked and 6 ? While it's common to believe that 7 back a deadline might reflect 8 on us and be en as unprofessional, we know relatively little from rearch about the actual 9 of asking for more time.
To better understand this, we 10 10 experiments and a survey with nearly 10,000 employees and managers in the U.S. We found that, 11 occupations, asking for more time to work on an assignment was, on average, 12 positively by managers—and it reduced employees' stress levels and improved their 13 . In one survey we did, of 191 employees, we found that 95% of tho who asked their manager for a deadline extension received one.
14 , employees rarely ask for an extension, even when deadlines are clearly 15 (e.g., their manager had explicitly said, "If you need more time, just ask"). For example, when we asked working adults 16 likely they would be to ask for an extension in a scenario where they felt highly time presd under a tight yet adjustable deadline, only 1 in 10 employees responded that they would.
Across our studies, employees— 17 female employees—worried that by asking for a deadline extension, their managers would think they were 18 and unmotivated. But in 19 to employees' predictions, managers judged both male and female employees who asked for an extension as more motivated than tho who did not. Managers did not
e employees as **petent 20 employees asked for an extension on a very urgent assignment.

Section Ⅱ Reading Comprehension
Part A
Directions: Read the following four texts. Answer the questions after each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET.
Text 1
. The average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution. The true number is likely to be many times higher, as only a small number of foods and drinks have been analyd for plastic contamination. The scientists reported that drinking a lot of bottled water drastically incread the particles consumed.
The health impacts of ingesting microplastic are unknown, but they could relea toxic
substances. Some pieces are small enough to penetrate human tissues, where they could trigger immune reactions. Microplastic pollution is mostly created by the disintegration of plastic litter and appears to be ubiquitous across the planet. Rearchers find microplastics everywhere they look; in the air, soil, rivers and the deepest oceans around the world.
Scientists do not know what happens when microplastics are inhaled, but the new study speculates that "most inhaled particles will be ingested" rather than coughed or sneezed out. The rearchers also estimated that microplastic particles ttling on to a single meal per day could add a further tens of thousands to the annual amount consumed. Cox was clear that there are no known health effects as yet, but he said the ingested particles are "a high exposure risk in terms of numbers. It could be a potential alarm call for sure."
The **mission's chief scientific advirs said in a report in April: "The evidence on the environmental and health risks of microplastics provides grounds for genuine concern and for precaution to be exercid." They concluded: "Growing scientific evidence on the
hazards of uncontrolled microplastic pollution, combined with its long-term persistence and irreversibility, suggests that reasonable and proportional measures should be taken to prevent the relea of microplastics."
Cox said his rearch had changed his own behaviour. "I definitely steer away from plastic packaging and try to avoid bottled water as much as possible," he said. "Removing single-u plastic from your life and **panies that are moving away from plastic packaging is going to have a non-trivial impact," Cox said. "The facts are simple. We are producing a lot of plastic and it is ending up in the ecosystems, which we are a part of."
