Have you ever wished that you could brush your teeth while you’re moving? It turns out that scientists have the answer. There’s a special kind of edible toothpaste（牙膏）you can actually eat. You can use it to brush your teeth and eat it afterward. Without the need to spit（吐出）, edible toothpaste is really convenient.
NASA invented edible toothpaste in the 1960s. They made it for astronauts in space and people called it “the astronaut toothpaste”. This is because spitting out toothpaste in space can be dangerous. Without gravity（重力）it can go everywhere and can damage spacecraft computers if it gets inside them. Edible toothpaste doesn’t foam（起泡沫）either so there is no mess.
If you don’t like the sound of edible toothpaste, there’s also a special toothbrush you can buy. When people travel to a place without water, they often use it. You just need to chew and it cleans your teeth just like you are using a normal brush. After you finish brushing your teeth, you spit it out and get rid of it. No mess and no worries.

( )74. If people spit out normal toothpaste in space, ________.
A. it will fall down to the ground B. it doesn’t foam and there’s no mess

亲爱的戴丽
今天早晨我和埃米一起去购物。她为某人买了件礼物。她有个秘密朋友吗？
下午我们遇到了几位朋友一道去买衣服了。丹尼尔情绪不好，整个下午没有跟任何人说过话。没有人能使他振作起来。西蒙一直不停地给某人打电话，但他不想告诉我们关于什么事情。他确信没有人能听到他在说什么。桑迪说了很多关于她自己的事情以致她没听到别人说什么。
那是很奇怪的一天，每个人似乎都有一个秘密或举止失常。也许我应该和某人谈谈这件事，但我想不起任何人可以和他谈。
