M: There you are. I’ve been looking everywhere for you. W: Well, you found me.

M: What are you doing in the library? W: I’m studying for our science test M: But it’s not for another two weeks.

W: Exactly. I’m already behind in my review. M: There’s still loads of time to prepare.

W: So you’re going to wait until the night before to study? M: I am, because that’s when I learn what I need to know.

W: Memorizing everything the night before isn’t learning. That’s cramming, and you won’t keep the knowledge. M: So? I only need to be able to recall the information for the test.

W: If you really want to learn, you have to review the material over a longer period of time. M: Cramming works for me. All I care about is getting a good grade. W: But you’re putting stress on yourself.

M: I don’t feel stressed. Anyway, I need pressure to study!

..B. Memorize everything on his notes. D. Skip lunch and hurry to the cinema.

B. Energetic but easily distracted. D. Ambitious but readily discouraged.

W: Really? You’re probably up most of the night cramming. A good night’s sleep before a test is important. M: I may be sleepy, but I get a good test score. Anyway, who wants to study on a Saturday? W: I do. That’s where we differ. I want to take every opportunity to prepare.

M: We still have two weeks You need to take a break. Let’s grab lunch and catch a movie. W: Thanks, but I want to stay focused. It’s important that I study the entire day. M: Wow, you are driven. But you need to eat.

W: I’ll grab something quick. I have my study time planned out with a few breaks. M: How can you concentrate for such a long time?

W: Easy. I go over my class notes and vocabulary lists chapter by chapter and quiz myself. M: That takes too much time. I can memorize everything in one night.

W: Good for you! You know? It’s very effective to study with friends. Why don’t you study with me for a while? M: For me, studying isn’t urgent. I want to have fun. Thanks anyway. Enjoy the library. W: Have a good day. Questions:

【解析】 【分析】

这是一篇议论文。无糖饮食已经爆炸式地进入健康领域，节食的倡导者认为过量的糖摄入可能会增加患心脏病和一些癌症的风险，所以一些人们避免吃甜食，一些人还建议不要吃乳制品。然而，研究表明，长期而言，节食是无效的，而且随着时间的推移，会导致体重增加。此外，无糖饮食令人困惑，并强加了一套没有科学证据的规则。这种限制性的饮食会造成对食物的恐惧或产生对食物不健康的看法。所以可以偶尔少吃一点糖，但不必为了健康而放弃糖。 【21题详解】

考查现在完成时。句意：现在，无糖饮食已经在健康领域炸开了锅，而且似乎已经成为许多人新年计划的首选。分析句意可知，本句为现在完成时，主语为sugar-free diet ，所以谓语为has exploded。故填has exploded。 【22题详解】

考查动名词。句意：一些人还建议限制奶制品的摄入。recommend doing sth“建议做某事”为固定短语。故填restricting. 【23题详解】

考查介词短语。句意：很多无糖的追随者不吃牛奶、酸奶和奶酪，由于他们认为这些产品含有糖分。分析句意可知，由于很多无糖的追随者认为这些产品含有糖分，所以他们不吃牛奶、酸奶和奶酪。所以空处填due to/ owing to/ because of“由于” ，其中to/of为介词后接名词assumption作宾语。故填due to/ owing to/ because of。

【24题详解】

考查形容词。句意：的确，我们正在吞下太多的甜食，平均每个美国人每天大约消耗20茶匙的添加糖。这里指的是被添加的糖，所以用ed结尾的形容词修饰名词。added“添加的”为形容词修饰名词sugar。故填 added。 【25题详解】

考查动词不定式。句意：但是你不需要为了健康的饮食而停止吃糖。need to do sth“需要做某事”为固定短语。故填 to quit . 【26题详解】

考查关系代词。句意：大脑将节食和对事物的限制解读为饥饿，这会导致脂肪的储存。分析句子可知，本句为which引导的非限制性定语从句，which代替前面的整个句子，作后面定语从句的主语。故填which . 【27题详解】
