阅读理解。    DNA is the whole "map" of the human body. It is something that all humans have, and it tells the body
what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
    People have been trying to understand the human body for a long time. In I860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called "genes"(基因) in
our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They"re written in the DNA with a special language.
    In 1961, another two scientists found the first "word" that they could understand in that language. It
shows how DNA tells the cell (细胞)to build its parts,(有几个单词看不清) the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

阅读理解。      What"s the most important thing for you to have in your life? Somebody mentions hard-work,
others suggest knowledge, love and luck.
      If you arrange (排列) the 26 English letters in order and use numbers to represent each of them,
for example, 1 for a, 2 for b, 3 for c…26 for z, you can change an English word into a number. So
hard-work becomes 8+1+18+4+23+15+18+11=98, meaning 98 is its mark. Knowledge: 11+14
+15+23+12+5+4+7+5=96, love: 12+15+22+5=54, and luck: 12+21+3+11=47, a small mark.
None of these words can give one a full mark. What about money? It can"t , either.
      Then what else? Don"t be worried. You can always find an answer to a problem in your life,
when you change your way of looking at things or doing things, or your attitude.Yes, attitude is the
word. See for yourself: attitude: 1+20+20+9+20+21+4+5=100, a full mark.
      Different attitudes lead to different courses of life. Most time people hope for a better life. It is
possible that they will have a better life if they chang their attitudes. When you change your manner
and became friendly towards others, you"ll meet more smiling faces towards you. In the same way,
if you take a positive attitude towards failure, you"ll find it"s also rewarding (有益的) though it has
caused you losses (损失).1. The writer thinks _____ is the most important thing in a person"s life. A. hard-work.
B. knowledge
C. money
D. attitude2. What is the mark of the word money according to the passage? A. 73
B. 72

阅读理解       Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs
on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the
same. Here are some fun things that you might not know about frogs. Enjoy!
       The Biggest and the Smallest Frogs
       Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest
frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
       The Best Jumpers
       Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by
other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is
like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is
50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the
earth.
       The Cryogenic Animal
       Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the
temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and
their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can
learn the way that the frogs do for medical purpose.1. The earliest frogs lived about ________ million years ago.A. 20

阅读理解       Text messaging, or simply "texting", with allows people to send and receive messages on mobile
phones, becomes very popular today.
       The advantages of texting are obvious. Texting helps to save money. If you have a few words to
greet your families and friends on their birthdays or on some important festivals, sending messages can
be cheaper than phone calling. Texting helps to save time. Even if you want to send a message to 100
people, you can do it one second. Texting helps you to "talk" to someone when he is too busy to answer
the phone. Texting can also help you to "talk" to someone secretly if you don"t want others to hear what
you are talking on the phone. These advantages are so amazing that many people are crazy about it.
They hold mobile phones in hands all day long, send dozens of messages each day, and even text while
driving or walking.
       However, texting has its disadvantages. Junk messages may come into your mobile phone box now
and then. When your phone box gets too full, you can"t receive any more messages. You may therefore
miss some important information.
       What"s more, if you don"t do texting properly, for example texting while driving or walking, it can be
dangerous. It can cause injuries and even death. It was reported that about 6,000 people were killed and
half a million were injured for this reason each year. In Fort Lee, a small town in New Jersey, USA, three people died because they walked into traffic while texting in 2011. Two researchers at Stony Brook
University, New York found that texters are 60% more probably to have an accident than others. When
people are texting, they don"t notice other people or things around them. To reduce traffic accidents, all
drivers of the UN are now not allowed to text while driving. About 32 countries have passed laws
restricting the use of mobile phones while driving.
       Texting is a wonderful way of communication. However, only when we use it properly, can we fully
enjoy the fun it brings.1. How many advantages of texting are mentioned in the passage?A. Two.
B. Three.
C. Four.
D. Five.2. What did the researchers at Stony Brook University find?A. Texters are easier to have an accident.
B. Texting is a good way of communication.
C. 6,000 people were killed and injured.
D. Many people text to greet families and friends.3. The underlined word restricting probably means _________.A. not telling
B. not allowing
C. enjoying
D. making4. This passage is written to tell us that __________.A. we should do less texting
B. texting has many advantages
C. texting is better than phone calling
D. we should do texting properly
