答案以及解析
一、单选题
1.答案：C
解析：考查一般现在时的被动语态。句意：这些蛋糕充满了巧克力。请尝一块。此处 cakes与fill之间为被动关系，应用被动语态。 be filled with意为"被……充满"；且根据语境可知，此句时态为一般现在时。故选C。
2.答案：C
解析：enough修饰形容词或副词时， enough要后置，先排除B和D；修饰动词要用副词，故答案为C。
3.答案：D
解析：—Jim, Betty刚才对你说了什么 —她想知道今晚我是否能和她一起去购物。宾语从句的语序为陈述语序,排除A和B两项。又因主句是一般过去时态,所以宾语从句也要用过去的某一时态,故选D。
4.答案：D
解析：句意:你必须强迫你自己远离电脑游戏。它们对你是有害的。force sb. to do sth.“强迫某人做某事”,故选D。
5.答案：C
解析：sure与certainly表示当然。
6.答案：D
解析：observe表示观察,see指观看实验,所以observe更接近题意。
7.答案：D
解析：upside down表示颠倒,倒转,over表示在... ...上方。
8.答案：A
解析：idea表示想法,观点。
9.答案：D
解析：考查动词短语辨析。句意: 飞机起飞大约40分钟后, 飞机的窗户坏了。get off下车; take up开始从事, 占用; get up起床; take off起飞。由句意可知选D。
二、单词填空
10.答案：method / way
解析：句意:大明总是找到解决数学问题的最佳方法。
11.答案：correct / right

12.答案：forced
解析：句意:红军被迫进行了长征。根据句意及空前的were可知此处用一般过去时的被动语态,故填force的过去分词forced。
13.答案：scientific
解析：句意:到目前为止,还没有科学研究表明鱼翅有益健康。修饰名词studies应用形容词, 故填scientific。
14.答案：filled with
