【解析】
【导语】本文主要介绍了杰克的个人信息。
1.句意:现在我是一个在阳光中学的学生。设空处位于主语“I”之后,故填 am。
2.句意:我会说中文。此处需表示“中文”这门语言。故填 Chinese。

用一般现在时。故填 is。

6.句意:它通常在下午 2:40 开始并在 3:40 结束。设空处与前半句的“begins”由“and”连接,为并列谓语,
因此动词 finish 需用第三人称单数形式“finishes”。故填 finishes。
7.句意:这令人放松并且体育老师和蔼又有趣。The PE teacher是三单,所以be动词用is。故填 is。
8.句意:我希望有一天我能像他一样打好篮球/打篮球打得更好。设空处修饰动词“play”需用副词,good
的副词形式是“well”,也可以用其比较级形式“better”。故填 well/better。
9.句意:我不吃汉堡或冰淇淋,因为我想保持健康。空后“I want to be healthy.”是空前“I don’t eat hamburgers
or ice cream”的原因。故填 because。
10.句意:如果你有空,请给我发电子邮件,地址是Jack66@happymail.com。“email”是及物动词,意为“给……
