[单项选择]

It has often been said by people involved in language teaching that a student who really wants to learn will succeed whatever the circumstances are under which he studies. It is certainly true that students do learn in unfavourable conditions, and it is also true that students of ten succeed using methods that experts have considered unsatisfactory. All teachers can think of some students who are significantly better than their peers, and it seems reasonable to suggest that the motivation of the student is perhaps the single most important thing that he brings to the classroom.
Motivation is some kind of internal drive that encourages somebody to pursue a course of action. It seems to the case that if we perceive a goal and if that goal is sufficiently attractive, we will be strongly motivated to do whatever is necessary to reach that goal. Of course, goals may be of many different types. Language learners who are motivated also perceive goals of various types, and
A. highly-motivated student with a long-term goal.
B. de-motivated student.
C. student who has to study because of the curriculum.
D. student with the urge to pass the exam.

[单项选择]Clearly, plastic does pose a threat to wildlife. But has its status as an environmental villain been exaggerated Many of the world’s most potent environmental threats are invisible, but plastic lingers in trees and rivers as a reminder of the consequences of our consumption. However, in some cases, plastic is environmentally the better option.
For example Riverford Organics, one of the largest vegetable box schemes in the UK, discovered that swapping short-lived cardboard boxes for more durable plastic ones could reduce the company’s carbon footprint from packaging by 70%. There was one problem. "Our customers hate plastic with a vengeance (极度地) ," the company’s website says. Even though paper and cardboard are responsible for 85% of the carbon footprint from packaging, virtually all complaints are about the plastic bags, which are responsible for only 8% of the footprint.
Guy Watson, the founder of Riverford, was prepared to make the investment in plastic boxes, but decided
A. They could decrease the company’s carbon footprint greatly.
B. They are more popular as they produce less carbon footprint.
C. They might cause plastic wastes in nature as a result of our consumption.
