    【题目】根据美国卫星拍摄的最新冰山照片显示：由于全球气候变暖，南极冰川开始融化，部分冰山从南极大陆边缘厚冰层中解体出来，并向附近海域漂移。据此完成下列各题。

    【1】冰川融化会导致海面不断上升，监测海面上升可以运用的地理信息技术是

    ①飞机②遥感③全球定位系统④地理信息系统

    A. ①② B. ③④ C. ②④ D. ②③

    【2】对冰山产生的原因进行分析和移动方向预测主要应用

    A. GIS B. GPS C. RS D. GPRS

    【答案】

    【1】C

    【2】A

    【解析】试题分析：

    【1】冰山与周围海水相比，温度和性质差异大，利用遥感影像可以迅速发现冰山的变化和移动方向、速度，所以适合用遥感技术来进行跟踪研究；对海平面变化的分析及移动方向预测主要靠GIS来完成。因此该题答案选C项。

    【2】对地理信息进行分析评估和预测主要是应用地理信息系统(GIS)。

    【题目】Passage 3

    Restaurant chefs, home cooks, and foodies — people who love good food — often say that we eat with all of our senses.

    First, we use our sense of sight to appreciate how a meal is presented, either on a dinner plate or a dining table. 1 Additionally, with our sense of smell, we breathe in the mouth-watering smell rising up from the meal. Finally, we enjoy the food with our sense of taste.

    But does sound also affect our dining experience? A new report from researchers at Brigham Young University said yes. Hearing is often called ＂the forgotten food sense.＂ says Ryan Elder, and assistant professor of marketing at Brigham Young University. 2 On the other hand, watching loud television or listening to loud music while eating can hide such noises. And this could lead to overeating.

    During the experiments, the test subjects wore headphones and listened to noise at either a high or low audio level. 3 The study found that subjects who listened to the higher volume noise ate more pretzels than those with the low audio levels.

    Elder says that when hiding the sounds of eating, like when you watch television or listen to loud music while eating, we take away the sense of hearing. 4 The researchers are calling this the ＂crunch effect＂, which they admit may not seem like much at one meal. But over a week, a month, or a year, all that food can really add up. So hearing the sound of eating /span>does reduce the amount of food you consume.

    5 Hearing the noises of your meal as you eat could also help you to be more mindful of the experience and perhaps help you to enjoy it more.

    A. In fact, beautiful food is healthier than food that doesn’t look appealing.

    B. But besides not overeating, there is another benefit.

    C. And this may cause you to eat more than you would normally.

    D. Then researchers gave them a hard snack: pretzels.

    E. Our sense of touch can also be important when preparing or sharing food.

    F. He notes that soft and sweet sound is thought to enhance the taste of food.

    G. He says that if people notice the sound the food makes as they eat it, they might eat less.

Before 1990, under the country’s Racial Segregation Law, coloured people and white people lived separately. Black people were treated unfairly even when taking a bus.

    Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young.

    ＂Although I did not enjoy the violence of boxing, I was inteested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat, ＂he wrote in his autobiography.

    As a skillful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.
