7．The teacher told us that the earth _______ around the sun．（ ）| A． | goes | B． | went | C． | going | D． | to go |
分析 老师告诉我们地球绕着太阳转．
解答 答案：A
根据The teacher told us that可知这是一个宾语从句，宾语从句虽然要保持与主句一样的时态，但如果宾语从句表示的是一个真理则使用一般现在时．结合语境可知宾语从句中描述的是客观性动作，故用一般现在时态．故选A．
点评 本题考查的是宾语从句的时态问题，理解句意并掌握宾语从句的用法是解答本题的关键．

19．Do you know how many bones are there in your body？When you were a baby you had about 330 bones，and now you have just over 200 bones．The number reduces because some bones join together as you grow．Your wonderful bones work together to protect you and support your body．
Many uses
Many bones protect your body．For example，the bone that makes up your head is called the skull．The skull surrounds your brain and protects it．The ribs that cover your chest protect your heart and lungs．
Other bones are used to support the body．The many bones in your feet allow you to walk，and stand on your tiptoes．Your hands and feet have more than half of the bones in your body!
Biggest Bone
The longest and strongest bone in your body is in your leg．It is called the femur and it goes from your hip to your knee．It is a very important bone because it carries all of your weight and helps you move from place to place．
Smallest Bone
Would you believe the smallest bone in your body is in your car？It is about the size of a grain of rice and is called the stirrup．When sound waves come into your car the stirrup shakes back and forth，allowing the sound waves to reach your brain．When the waves reach your brain you bear the sound．
"Funny"Bone
Hah!The funny bone isn't really a bone at all．It is actually a nerve （神经）．When you hit the nerve that is near your elbow，it really hurts or tingles．What's so funny about that？The funny bone probably got its name from the bone that is above your elbow．That bone is called the humerus，which sounds like the word"humorous"，meaning"funny"．
The bones that make up our bodies help us grow，and allow us to move．When you think，about it our bones really are wonderful．
