Barrier Islands

Texas has an extensive coastline that runs along the Gulf of Mexico. If you look closely at the map, you’ll notice that there are narrow islands located just off the coast of Texas. These are called barrier islands.

Barrier islands stretch along about 15 percent of the world’s coastlines. They are separated from the mainland by a shallow body of water. Some barrier islands spread out for more than 100 miles. In Texas, some of the largest barrier islands include Galveston Island, Mustang Island, and Padre Island.

Barrier islands are fragile (脆弱的) areas that contain an interdependent community of land, plants, and animals. All three need each other to exist. If one is harmed in some way, then the other two can suffer. For example, barrier islands are in constant danger of erosion, or loss of land, from wind, waves, and people. The steady movement of ocean waves and wind moves sand along the beaches. This movement contributes to erosion, which changes the shape and size of a barrier island over time. Plants not only provide animals with food and shelter, but it also helps keep an island’s sand and soil in place. When people pick native plants, it advances the process of erosion. This can harm the environmental balance that keeps an island’s ecosystem healthy. For this reason, visitors to barrier islands are usually warned to leave plants alone and to stay on roads and public beaches so that the land, plants, and animals are not disturbed.

As their name suggests, barrier islands provide a natural barrier that helps block the mainland from very bad weather such as strong windstorms and hurricanes. This protection saves lives, homes, and money every year. Barrier islands are also a major source of income for an area’s economy. Padre Island, for example, is visited every year by hundreds of thousands of tourists who take advantage of its sandy beaches and beautiful waters that are perfect for swimming, boating, and fishing. The dollars that tourists spend on the island help financially support the region and state.

第二部分：阅读理解（共20小题;每小题2.5分，满分50分）

    阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

Proper arrangement of classroom space is important to encouraging interaction. Most of us have noticed how important physical setting is to efficiency and comfort in our work. College classroom space should be designed to encourage the activity of critical thinking.

We have entered the 21st century, but step into almost any college classroom and you step back in time at least a hundred years. Desks are normally in straight rows, so students can clearly see the teacher but not all their classmates. The message behind such an arrangement is obvious. Everything of importance comes from the teacher.

With a little imagination and effort, unless desks are fixed to the floor, the teacher can correct this situation and create space that encourage interchange among students. In small or standard-size classes, chairs, desks, and tables can be arranged in a variety of ways. The primary goal should be for everyone to be able to see everyone else. Large classes, particularly those held in lecture halls, unfortunately, allow much less flexibility.

Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with movable desks and tables present no problem. Even in large lecture halls, it is possible for students to turn around and form groups of four to six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out loud, and see how other students’ thinking processes operate all essential elements in developing new modes of critical thinking.

In courses that regularly use a small group format, students might be asked to stay in the same small groups throughout the course. A colleague of mine, John, allows students to move around during the first two weeks, until they find a group they are comfortable with. John then asks them to stay in the same seat, with the same group, from that time on. This not only creates a comfortable setting for interaction but helps him learn students’ names and faces.

1. The primary purpose of desk rearrangement is _______.

       A. for the teacher to divide students into small groups.

       B. to make it possible for students to interact with each other.

       C. for the teacher to find out how students think.

       D. to give students more opportunities to practice speaking.

2. The expression “step back in time at least a hundred years” in Paragraph 2 is intended to convey the idea that _______.

       A. there is not much change in educational idea over the past hundred years

       B. critical thinking was encouraged even a century ago

       C. college classrooms often remind people of their college life

       D. a hundred years ago, desk arrangement in a classroom was quite different

3. The greatest advantage in allowing each student to find his own group might be that________

       A. learning is made comfortable in this way

       B. the teacher can easily remember students’ names and faces

       C. the teacher saves the trouble in doing that

       D. brighter students can help slower ones.

4. It is implied in the passage that ______.

       A. students are allowed to changed groups throughout the course in John’s class

       B. classroom interaction between students is essential to the teachers

       C. a comfortable environment leads to higher working efficiency

       D. new kinds of desks and chairs should be made

       A. create a comfortable setting for interaction

       B. introduce an approach of learning students’ names and faces easily

       C. give an example that students stay in the same seat throughout the course.
