During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you’re tired. Sleep gives your body a chance to rest.
But your brain (大腦)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(記憶). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
You also grow while you sleep. The thing called "human growth hormone (荷爾蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陳代謝) slows down. You are still using some energy, but much less than when you are awake and active.
Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body’s way of saying, "I need sleep！" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.
小題1:What does "human growth hormone" do while people sleep?
A．It helps people rest well.B．It helps repair the body.
C．It helps answer problems.D．It helps slow the body down.
小題2:According to the passage, which of the following tells you need sleep?
A．You use up a lot of energy.B．You enjoy daily activities.
C．Your body temperature falls.D．You don’t want to get up.
小題3:What does the underlined word "conserve" mean?
A．provideB．moveC．saveD．spend
小題4:What is this passage mainly about?
A．Sleep is very important.B．The brain needs enough sleep.
C．Good ways to sleep well.D．People use energy when sleeping

小題1:B
小題2:D
小題3:C
小題4:A

小題1:根據(jù)短文第三段You also grow while you sleep. The thing called "human growth hormone (荷爾蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.描述,可知選B.
小題2:根據(jù)Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body’s way of saying, "I need sleep！"描述,可知選D.
小題3:聯(lián)系下文,當(dāng)你睡覺時(shí),體溫降低,新陳代謝變慢,可知睡覺有助于你儲(chǔ)存能量,故C.儲(chǔ)存.
小題4:這篇短文主要從各方面論述了睡覺對(duì)我們很重要,故選A.

Many companies use guards and expensive alarm systems to protect their property(財(cái)產(chǎn))。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡邏) factories, warehoues(倉庫)，and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.
小題1:Why is the new kind of robots called mobile robots?
A．Because they are able to climb stairs.B．Because they are able to send an alarm
C．Because they can open doors.D．Because they can move around slowly on wheels
小題2: How will a robot get directions for moving around a building?
A．From a human guard .B．From a built- in computer.
C．From another robot .D．From radio signals.
小題3: What does the underlined word barred mean?
A．protectedB．a(chǎn)llowed .C．markedD．prevented
小題4: According to the text, a mobile robot will NOT be able to ___________.
A．sense whether something has been moved.B．sense a cat crossing the room.
C．move over rough ground .D．detect people through walls.
小題5:This text mainly describes how robots will ___________.
A．protect the museumB．set off a siren .
C．judge the size of a person.D．patrol buildings.
