plant species that are well adapted to survival in dry climates are being looked at for an answer in developing more efficient crops to grow on marginally arable lands.

Plants use several mechanisms to ensure their survival in desert environments. Some involve purely mechanical and physical adaptations, such as the shape of the plant's surface, smaller leaf size, and extensive root systems. Some of the adaptations are related to chemical mechanisms. Many plants, such as cacti, have internal gums and mucilage which give them water-retaining properties. Another chemical mechanism is that of the epicuticular wax layer. This wax layer acts as an impervious cover to protect the plant. It prevents excessive loss of internal moisture. It also protects the plant from external aggression, which can come from inorganic agents such as gases, or organic agents which include bacteria and plant pests.

Researchers have proposed that synthetic waxes with similar protective abilities could be prepared based on knowledge of desert plants. If successfully developed, such a compound could be used to greatly increase a plant's ability to maintain health in such adverse situations as inadequate water supply, limited fertilizer availability, attack by pests, and poor storage after harvesting

The word “aggression” in the 2^nd paragraph is closest in meaning to_________

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.

Just as you designate and separate your physical workspace, you should be clear about when you’re working and when you’re not. You’ll get your best work done and be most ready to transition back to the office if you stick with your regular hours. Plus, if your role is collaborative, being on the same schedule as your coworkers makes everything much easier.

“The biggest difference between working from home and working in the office is that you are in charge of your environment and have to treat yourself like an employee,” Yurovsky says. This means holding yourself accountable, but also recognizing when enough is enough, just as a good manager might. “If you feel yourself extending your work hours because you are not doing anything in the evening...tell yourself it’s time to put work away, recharge, and start tomorrow with a fresh mind. The work will be there in the morning.”

If you live with other people, this separation is even more critical. Communicate with the people whom you live with to establish boundaries so you can cut down on distractions during the workday—and then disconnect and give the people you care about your full attention. Having a separate time and space to work will allow you to be more present in your home life.

Sir Isaac Newton, the English scientist and mathematician, was one of the most important figures of the 17th century scientific revolution. One of his greatest achievement was the discovery of the three laws of motion, (26) ______ are still used today. But he also had a very unusual personality. Some people would say he was actually insane.

His father died before he was born, and his mother soon remarried. The young Isaac hated his stepfather so much that he once (27) _____ to burn his house down - when his stepfather and mother were still inside! Fortunately he did not, and he went on to graduate from Cambridge without being thrown into prison.

Isaac's first published work was a theory of light and color. When another scientist wrote a paper criticizing this theory, Isaac flew into an uncontrollable rage. The scientist (28) ______ for the criticism was a man called Robert Hooke. He was head of the Royal Society, and one of the most respected scientists in the country. (29)_______, this made no difference to Isaac, who refused to speak to him for over a year.

The simple fact was that Isaac found it impossible to have a calm discussion with anyone. As soon as someone said something that he disagreed with, he would lose his temper. For this reason he lived a large part of his life isolated from (30) ______ scientists. It is unlikely that many of them complained.
