[填空题]Over the past four years, more than half of students in the high school caught receiving text messaged answers on their cell phones during an accounting exam.
[单项选择]This past Thursday, more than 400 people showed up to the Stinson Auditorium for Professor John Wallace’s speech. Unfortunately, Professor Wallace wasn’t among them. It was not until after everyone had taken their seats in the auditorium that they learned the professor would not be able to make it.
Early reports indicate that a scheduling mix-up kept the professor from making his appearance. At the time when he was supposed to be speaking to a crowd here in Stinson about literary history, he was giving a lecture on modern journalism at an event in Pittsburgh. Representatives for Professor Wallace have issued multiple apologies to the people of Stinson, assuring them the error was an accident.
Thus far, it appears as if they have forgiven him. Tickets for his rescheduled Stinson appearance, this coming Saturday afternoon, have already sold out. It is likely that attendees are most excited to hear the professor talk about his latest bestselling novel, The Artificial Writer. But
A. A disturbance on a college campus
B. The rescheduling of a speaking event
C. A recently released book about writing
D. The reason a planned book signing was canceled

[单项选择]Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habit, because much of the food they eat, particularly processed foods, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming today.

In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the a-mount—but not the quality--of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healt
A. They want to return to nature.
B. They want to eat all kinds of foods.
C. Natural foods are very delicious.
