　　People are wiser and can do more things than other animals because of their wonderful brains. We can talk, read, write, build houses, and invent things. Your brain has three main parts：the front brain, the hind brain, and the middle brain.

　　The front brain is the largest. It is gray outside and white inside. This is the part of the brain where you remember, think, and plan. With this part of your brain you make your arms and legs do what you want them to do. Here is where the messages from the eyes, ears, and nose let you see, hear, and smell. The hind brain is smaller than the front brain and is more like that of other animals. This part of the brain gives you balance and control of your muscles. You walk without tripping and skip without falling because the hind brain is doing its job. If it were not, you would lose your balance and fall over.

　　The middle brain is the smallest of all, but very important. It controls the beating of your heart, swallowing food, breathing, and other things you do without thinking. The middle brain is a small swelling where the brain joins the spinal cord－a large bundle of nerves in your backbone. The spinal cord is the main road to and from the brain. It comes into the middle brain bringing messages from all parts of your body. It also takes charge when some part of your body is in danger. If you touch a hot iron, the message to the spinal cord makes you pull your finger away even before you feel the pain of the burn. This is called a reflex. Nerves conned most parts of your body to the spinal cord.

1．What is the main idea of the passage?

[　　]

A．How brains make people intelligent.

B．How your brain is connected with most parts of your body.

C．How the spinal cord in your body works.

D．How each part of your brain functions.

2．Which part takes charge when one is designing his research project?

[　　]

3．The spinal card leads to your

[　　]

4．What does the underlined word “that” in the second paragraph refer to?

[　　]

A．The front brain.

B．The hind brain.

C．The smaller brain.

D．Other animals' brains.

5．If you cut your finger, how can your brain know it?

[　　]

A．Your heart feels it and lets your brain know.

B．When you see the blood, your eyes will send the message to your brain.

C．Your backbone collects the message and sends it to the brain.

D．Your spinal cord collects the massage and sends it to the brain.

       The Eiffel Tower is beautiful, and a must-see. It is about 1,050 feet high and was the world's tallest
building until 1930. Designed by Gustave Eiffel, it originally had no practical use and was built as a
centerpiece for the World Fair of 1889. Today it is the very symbol of Paris.
       It is made of iron and weighs 7,000 tons. It always seems to be so busy around the tower-crowds of
tourists and lots of street sellers selling souvenirs. Visitors can take the elevator to get to the top of the
tower. On the top of the tower, visitors can enjoy the sunset. The sunset is beautiful and amazing.
       On the top of the tower, visitors can get a 40-mile view, the twinkling nighttime lights of the city make a pretty sight, but it is difficult to tell from any landmarks (路标).
       It is a hugely impressive sight at daylight, but at nighttime becomes magical. It shines with 20,000
