A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."

A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon.

　  What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all.

　　From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons (架线塔).

　　Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear (齿轮) is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered (改变) and can not be fully trusted.

　　These crash photos and videos shown here clearly have been doctored (篡改) and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma.

Babies born in summer are more likely to become short-sighted in late life, a study has shown.
As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300,000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.
Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted.”
67. Babies born in summer are more likely to be shortsighted ____________.
A. because the summer sun is too strong for babies
B. because babies born in summer have lengthened eyeballs
C. if they are exposed to much sunlight in the first weeks after they are born
D. if parents don’t know a proper way to protect their babies’ eyes
68. Melatonin is a kind of material to ___________.
A. prevent the eyes from becoming near-sighted
B. protect the skin from harmful sun rays
C. make our body strong
D. protect babies’ eyes from summer sun
69.From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that shortsightedness is related to exposure to sunlight
B. whether light exposure affects sight still needs to be further proved
C. he believes that light exposure can cause shortsightedness
D. he tries to give the cause of why light exposure affects sight
70.The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed                         B. resistant
C. protective                               D. changeable

●What prevents depression：tea，coffee or hot chocolate?
Women who drink for or more cups of coffee a day are a fifth less likely to become depressed．Drinking two or three cups reduces the risk by 15 percent. This is the result of a study of 51,000 women over ten years, published in the Journal of the American Medicine Association.
One theory is that caffeine reduces the  effect of the chemical adenosine(腺苷) in the brain, which can make us feel sleepy by slowing down nerve cell activity. Some anti-depressants also work by blocking the adenosine receptors. Coffee was found to be far more influential on depression levels than hot chocolate or tea due to the high caffeine content.
●How many eggs can we healthily eat: one a day or two a day?
Neither-eat them freely. We’ve long been warned to stick to two or three eggs a week because of their high cholesterol(胆固醇)content. But according to the Food Standards Agency, there is no recommended limit to how many eggs we can healthily eat, unless you have been told to cut down by your doctor.
There is no evidence that eating eggs raises cholesterol levels, and researchers found that eggs contain less cholesterol than in the past because hens are no longer given bone meal, which was banned in the 1990s after the BSE(疯牛病) cresis.
Research by the British Egg Council found that a medium egg gives you around 100 mg of cholesterol, a third of the 300mg recommended daily limit.
【小题1】What is considered to fight depression best?

A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."
