Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather. But water also can be dangerous for kids if you don't take great care. Nearly 1,000 kids die each year by drowning.
Here are some tips to keep your kids safe in the water:
At the Lake or Pond
·Don't let little kids swim alone without adult supervision— lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore.
·Ponds and lakes may hide jagged rocks, broken glass, or rubbish.
·Make sure kids wear foot protection; even in the water, they should wear socks or water shoes.
·Watch out for weeds and grass in the water that could trap a leg or arm.
·Most boating accidents, particularly among teenagers, are related to alcohol(饮酒). Be sure teens know about the dangers of alcohol, on and off the water.
At the Beach
·Teach kids to always swim when and where a lifeguard is on duty. Unlike the calm waters of a swimming pool, the beach has special dangers like currents and tides(暗流). Check with the lifeguard when you arrive to find out about the water conditions.
·Tell kids never to stand with their back to the water because a sudden wave can easily knock a child over.
·Teach kids that if they're caught in a dangerous wave, they should swim parallel（顺行地） to the shore or should tread （踩）water and call for a lifeguard's help.
Whether at the lake or at the beach, teach your child to get out of the water during bad weather, especially lightning.Which is the right behavior when swimming at the beach?
| A．Go off the water without a lifeguard on duty |
| B．Go on swimming in a heavy rain |
| C．Go off the water after checking the water conditions |

| A．there are no lifeguards at a beach |
| B．there are currents and tides at a beach |
| C．the waters of a beach are more calm. |

Four people in England back in 1953, stared at Photo 51,It wasn’t much—a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed –the shape of DNA The discovery brought fame and fortune to scientists James Watson, Francis Crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.
Her name was Rosalind Franklin.”She should have been up there,” says historian Mary Bowden.” If her photos hadn’t been there, the others couldn’t have come up with the structure.” One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors
At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at King’s College in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflection the shape.
But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant .But the college actually employed her to take over the DNA project.
What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to go or be put in her place.”
As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklin was only two steps away from the solution.”
No, Franklin was the solution. “She contributed more than any other player to solving the structure of DNA . She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the“Dark Lady of DNA”, Franklin is finally coming into the light.What is the text mainly about?
A. The disagreements among DNA researchers.
B. The unfair treatment of Franklin.
C. The process of discovering DNA.
D. The race between two teams of scientists.Watson was angry with Franklin because she .
| A．took the lead in the competition | B．kept her results from him |
| C．proved some of his findings wrong | D．shared her data with other scientists |
Why is Franklin described as“Dark Lady of DNA”?
A. She developed pictures in dark labs.
B. She discovered the black X-the shape of DNA.
C. Her name was forgotten after her death.
D. Her contribution was unknown to the public.What is the writer’s attitude toward Wilkins, Watson and Crick?
| A．Disapproving. | B．Respectful. | C． Admiring. | D．Doubtful. |

How I Turned to Be Optimistic
I began to grow up that winter night when my parents and I were returning from my aunt＇s house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times. ”
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: Almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy. How did the author get to know America?

When you practice reading with passages shorter than book length, do not try to take in each word separately, one after the other. It is much more difficult to grasp the broad theme of the passage this way, and you will also get the stuck on individual words which may not be absolutely essential to a general understanding of the passage. It is a good idea to skim through the passage very quickly first to get the general idea of each paragraph. Titles, paragraph headings and emphasized word can be a great help in getting this skeleton outline of the passage. It is surprising how many people do not read titles, introductions or paragraph headings. Can you, without looking back, remember the title of this passage and the heading of this paragraph?
Most paragraphs of a passage or chapter have a 'topic sentence' which expresses the central idea. The remaining sentence expand or support that idea. It has been estimated that between 60% and 90% of all expositive（说明的）paragraphs in English have the topic sentence first. Always pay special attention to the first sentence of a paragraph; it is most likely to give you the main idea.
Sometimes , though , the first sentence in the paragraph does not have the feel of 'main idea' sentence. It does not seem to give us enough new information to justify a paragraph. The next most likely place to look for the topic sentence is the last sentence of the paragraph.
Remember that the opening and closing paragraphs of a passage or chapter are particularly important . The opening paragraph suggests the general direction and content of the piece, while the closing paragraph often summarizes the very essence （精髓）.It is a good idea to skim through a passage quickly first ________.
| A．at about 350 w. P.m.(words per minute) |
| B．to get the general idea of each paragraph |
| C．so that you can take in each word separately |
| D．to make sure you get to the end at least once |
