Planet DannyPPT，第三部分内容：教材解读
1.When they arrive,Danny is outside in the yard.
arrive为不及物动词,意为“到达,来到”,后接表地点的名词时,需使用介词in或at。in用于指较大的地点,at则指比较具体的小地点。arrive at/in与get to/reach同义。
2.He said that I could use his telescope.
本句含有that引导的宾语从句。无论主句是陈述句还是疑问句,宾语从句都应使用陈述语序。含宾语从句的复合句,主从句谓语动词的时态呼应包括以下三点:
(1)如果主句的谓语动词是一般现在时,宾语从句的谓语动词可根据需要,选用相应的时态。
(2)如果主句的谓语动词是一般过去时,宾语从句的谓语动词应用相应的过去时态。
(3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句用什么时态,从句时态都用一般现在时。
3.Danny turns the telescope around and looks through it again.
turn around/round意为“调转方向,转身”。
4.Maybe Brian and I can join you after supper.
◆maybe为副词,意为“也许”;may是情态动词,也表示“也许”,但后面必须跟动词原形。
◆join为及物动词,意为“参加,加入”,其后可接人,也可接表示团体、组织、党派等的名词。join为非延续性动词,和表示一段时间的状语连用时应变为be in。
5.I don’t think you can find one unless you have a bigger telescope.
unless为连词,意为“除非,如果不”。由unless引导的条件状语从句既可以是真实条件,也可以是非真实条件。unless通常相当于if…not…。
6.Actually,double the size of your house!
double可作名词或形容词,意为“两倍(的);双重(的)”,也可作动词,意为“使加倍”
