题目内容
There ____________ a lot of food at home.
| A．are | B．is | C．have | D．has |
B
解析试题分析：There be句型表示“某地(或某时)存在有某人(或某物)，而并非某地(某人、某物或某时)拥有什么东西”，句中有若干个名词作主语，动词be常与后面主语中的第一个名词在数上一致。have一般表示某人有某物。句意：我家有许多食物。Food是不可数名词，故谓语动词用单数。选B。
考点：there be句型就近原则
点评：There be句型表示“某地(或某时)存在有某人(或某物)，而并非某地(某人、某物或某时)拥有什么东西”，其实质是倒装句，其谓语动词就近原则是常考内容，注意基本规则就行。

What do you do if you're in trouble on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.
Body signals (信号)
Pilots from different countries understand body signals if they have the correct training, When you wave your arms up and down in a straight line, it means, "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend (弯曲) your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.
Smoke signals
The smoke from a fire can be seen from far away, so it’s a good way to draw attention. If the weather is dry, it isn’t hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a tire unless you're sure that it can’t spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.
Ground-to-air signals
It's a good idea lo build some signals, too. Use large pieces of wood to make the symbols (标记). If you can't find any wood, use earth. Some useful symbols are:
F "I need food and water"
II "I need medicine."
I "I am badly hurt."
X "I am unable lo move from here."
Pilots' replies
If the pilot lowers the plane's wings from side to side, this means: "message received and understood" (At night, the pilot flashes the plane's green lights.) If the pilot flies the plane in a clockwise circle, this means "message received hut not understood" (At night, the: pilot flashes the plants red lights.)
However, there is no signal which means "message not received. Why not'?
