The human body has hundreds of muscles. The three types are skeletal(骨骼的) muscles, smooth muscles and cardiac, or heart muscles. Each kind of muscle has a special job to do.
The skeletal muscles are attached to the bones; they actually hold the skeleton together. Strong cords, called tendons(肌腱), help connect these muscles to the bones. Skeletal muscles give us strength and allow us to move in many ways. If you look at skeletal muscles through a microscope, you will see that it has bands of fibers that look like stripes(条纹). These stripes are called striations. Skeletal muscles usually move because the brain has sent a conscious message to them telling them what to do. This is called voluntary movement.
Another type of muscle is smooth muscle. Unlike skeletal muscle, smooth muscle does not have striations. This is found in organs such as the stomach, the bladder(膀胱), the lungs and the eyes. Smooth muscles are smaller than the skeletal muscles and they move involuntarily. The brain tells these muscles what to do, but we aren’t even aware of it. For example, we don’t have to think about breathing or digesting food. The smooth muscles just do their jobs automatically. For this reason smooth muscles are sometimes called involuntary muscles.
Like smooth muscle, cardiac muscle also works involuntarily. It is a very thick muscle that is found only in the walls of the heart. Its job is to pump blood out of the heart and into blood vessels called arteries(动脉). The arteries help carry the blood to all parts of the body. When the cardiac muscles relax, they let blood back into the heart. Cardiac muscles have striations, just like skeletal muscles do.
When we _______, the job is done by smooth muscles.

A．close our eyes

B．kick a ball

C．hug our friends

D．lift a suitcase

Skeletal muscles and heart muscles are alike because_______.

A．both can move voluntarily

B．both are thick muscles

C．both are bigger than smooth muscles

D．both have stripes called striations

Which of the following is TRUE according to the passage?

A．Heart muscles are very important because they give us strength and allow us to move.

B．The heart of human beings completely consists of heart muscle.

C．The skeletal muscles are connected to the bones by tendons.

D．Smooth muscle does its work without receiving message from the brain.

I’ve often had difficulty remembering names. Proper nouns seldom found easy purchase in my brain unless I consciously repeat them over and over again. Needless to say, when people leave my life their names are often soon forgotten. This can have some embarrassing consequences.
Five or six years after high school graduation, I was reading carefully the shelves of a local auto supply shop when I noticed someone familiar enter the store. I knew him. He was in my graduation class and although he was not a good friend of mine, we had shared many classes and knew each other well. I began to feel an increasing sense of foreboding（预感）and quickly hid behind the nearest shelving unit. I should have known his name. How many times had I heard it during class role call? How many conversations had we had in the hallways?
I easily remembered his surname, “Ricca”. His was a large, well know family in the town of my childhood. I couldn’t have just acknowledged him using his surname. I might as well have admitted forgetting his name, which was not a choice. One’s name is important to every person’s identity. Not remembering an old acquaintance’s name is similar to forgetting your wife’s favourite flower, an embarrassing mistake of the highest order.
I quickly ran through the alphabet (字母表), a strategy I developed for just such an occasion. Abe? No, Adam, Andy, Bob? No, Bill? Yes! Bill sounded right. Of course, his name is Bill. I confidently made my way around the shelves and spoke to him as he was studying some cans of motor oil.
“Bill, how are you doing?”, I said offering him my hand which he took with a friendly shake. We talked a bit, some amusing remarks about our college experiences and such. I took his hand again, said how good it was to see him and gave him a happy wave, calling him by name again, as I left.
I was so pleased that I avoided yet another awkward encounter(相遇) that I could feel a big smile on my face as I paid the cashier and exited the store. As I marched merrily across the parking lot, an awful thought came into my mind. John, his name is John! Where did Bill come from? Was that one of my brothers? The sudden realization of what I did made me stop in my tracks. My head dropped when I realized my mistake. There was no way Mrs. Ricca would name one of her sons “Bill”. “Billerica” was the name of a town just north of Boston.
Which one can show the charge of the writer’s feelings?
a. guilty b. anxious c. embarrassed d. happy e sure

A．a-d-b-e-c

B．d-e-b-a-c

Ladji Doucoure of France beat Olympic champion Liu Xiang of China in the final meters to claim the title of the men’s 110 meters hurdles at the 10^th world championships in Helsinki on Friday.
Doucoure, who led the world this season with 12.97 seconds, over took the Chinese to win the race in 13.07 seconds. Liu was second in 13.08. Four-time world champion Allen Johnson of the United States took the third in 13.10.
The 22-year-old Doucoure said after the race, “ I can not tell you just how long I have been dreaming of this. This victory is the result of a lot of hard work, and also a lot of support from people who have believed in me. I had a bad start, touched a few hurdles, but after the 4^th hurdle I picked up my race and went straight to the finish line.”
Liu, who won the Olympic gold with a world record-tying time of 12.91 seconds, said, “I’m very satisfied with the second place. The result could have been worse. I felt quite well and did my best. I’ m not tired, I had some clearance problems at the start, so I should practice that some mor. Finally, I didn’t lose by much, only by a little bit, but I did think I could win it.”
Liu’s coach, Sun Haiping said on Friday he was content with Liu’s performance.
“ Liu Xiang was quite good during his reaction period, but he was a little bit slow in the middle and he finally caught up during the last two hurdles,” Sun told Xinhua.
Although satisfied with the silver medal and the clocking of 13.08 seconds, Sun said Liu might have added the world title to the Olympic championship if Liu had run the track neighboring his major rivals(对手) of Doucoure Ladji or Allen Johnson.
“ If he had run next to Ladji Doucoure or Allen Johnson, Liu could have kept pace with them and then sprinted(疾跑) at the last stage. In this case, he could grab the gold,” said Sun, who had become a household name for coaching China’s first men’s Olympic champion in the track.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seed. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.
The main idea of the first paragraph is that ______.

A．plants are important for life

B．plants cannot grow without air

C．there are many plants in the world

D．we can’t live without water

plants can make food from _______.

A．flower, water and air	B．water, sunlight and air
C．air, water and soil	D．air, sun and light

What can we infer from the passage?

A．Of all living things animals are most important.

B．Spores are seeds.

C．All fruits of flowering plants have seeds.

D．Without plants, man will die out
