Global warming could make humans shorter, warn scientists who are said 【小题1】(find)evidence that it caused the world’s first horses to shrink nearly 50 million years ago.

In fact, a team from the universities of Florida and Nebraska says it has found a link between the earth 【小题2】(heat)up and the size of mammals — horses. The scientists used fossils to follow the evolution(进化)of horses from their earliest 【小题3】(appear)56 million years ago.

“As temperatures went up, 【小题4】(they)size went down, and vice versa; at one point they were as small as a house cat,” said Dr. Jonathan Bloch, curator of the Florida Museum of Natural History. The scientists say that the current warming could have the same effect 【小题5】 mammals — and could even make humans 【小题6】(small).

Horses 【小题7】(start)out small, about the size of a small dog like a miniature schnauzer.【小题8】 is surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that 【小题9】(exact)agrees with the global warming event. “It had been known that mammals were small when it was warm,【小题10】 we hadn’t understood that the temperature really was driving the evolution of body size,” Dr. Bloch said in the Science journal.

EQ is a way of 【小题1】(measure) how a person recognizes emotions in himself or herself and others , and makes these emotional states work better as a group or team. IQ is a value that 【小题2】(indicate) a person's ability to learn, understand, and apply information and skills in a meaningful way. The major 【小题3】(differ)between EQ and IQ is what part of a person's mental abilities they measure; understanding emotions or understanding information.

According to some 【小题4】(theory)of brain function, a high EQ means someone is self-confident ,self-aware, and able to handle difficult emotional experiences. It is often tied directly 【小题5】 the degree of success a person may have in the workplace and in 【小题6】(person)relationships. People with high EQs can often better recognize and control their own emotions, and recognize  emotional states of others 【小题7】(adjust)their behavior accordingly.

A person's IQ, on the other hand, measures concepts like logical reasoning and math skills rather than creative potential or emotional abilities. People with high IQs may be able to learn certain subjects very quickly and make connections between ideas 【小题8】 will be missed by others. They often have great academic success, 【小题9】 they may struggle to find classes that challenge them. The ability to acquire knowledge does not 【小题10】(necessary)mean people can recognize and manage their own emotional states , however.

   Cellphones, tablets, and computers are keeping children and teenagers awake at night-even when they' re not in use, according to new research. A study published on Monday in JAMA Pediatrics says that media devices are causing kids to sleep less and reducing the quality of sleep that they get. This leads to trouble of staying awake the next day.

Researchers analyzed hundreds of studies of children and teens aged 6-19. The scientists found a strong and consistent association between the use of technology at bedtime and poor sleeping. The reason is not just that kids are staying up too late with their devices. Using a computer can overstimulate the mind and emotions, the researchers say. A smartphone or tablet also gives off a light that affects the body's natural timing. These factors contribute to poor quality sleep. And many kids could be at risk. According to the study,72% of all children and 89% of adolescents have at least one device in their sleep environment. Most of these devices are used near bedtime.

"The harmful association between screen-based devices and kids' sleep is a major public health concern," the study concludes. In their conclusion, the researchers urge parents to understand the damaging influence of device use before sleep.

【小题1】What do the researchers disagree with?
A.Children even in dreams can be influenced by media devices.
B.Most adolescents like to play media devices before sleep.
C.Using media devices on bed makes kids sleep difficultly.
D.Using media devices can not excite the mind and emotions.
【小题2】How does a smartphone affect a child's sleep?
A.By making noises.
B.By giving off a light.
C.By attracting a kid's attention.
D.By sending out electronic waves.
【小题3】What can we learn from the second paragraph?
A.Media devices anytime put kids in danger.
B.Adolescents are more easily affected than children by phones.
C.Using technology at bedtime causes poor sleeping.
D.Media devices affect kid's performance at school.
【小题4】Whom does this article most probably writes to?
A.Scientists.B.Parents.
C.Children.D.Producers.

   Do you like eating processed meat? If you do, think twice now if you want to eat such meat for the sake of your health.  Why? "It's because eating processed meat can cause cancer, " World Health Organization (WHO) experts said last Monday.

Processed meat is the meat that has been preserved by salting, smoking, drying or canning. Experts from the WHO's International Agency for Research on Cancer (IARC) in Lyon, France studied 800 patients.  The experts connected processed meat, such as hot dogs and bacon, with at least three kinds of cancer.  A person who eats 50 grams of processed meat per day— about two pieces of bacon— increases his or her risk of bowel (肠) cancer by 18 percent.

The IARC has included processed meat in its Group 1 list, for which there is " enough evidence" of its connection with cancer. Tobacco is also on the Group 1 list.

The experts also said red meat, including beef, lamb and pork, is "probably" carcinogenic (致癌的)to humans. Dr. Kurt Strait is with the IARC. He said in a statement that the risk of cancer increases with the amount of meat a person eats. Health experts in some countries advised people against eating large amounts of red and processed meat. But those suggestions had been centered on the increased risk of heart disease and obesity.

However, meat industry groups protest the result of the WHO's study.  They say that meat is part of a balanced diet.  They also say the causes of cancer are broad, and include environment and lifestyle factors.

The WHO's report cites (引证) the Global Burden of Disease Study's project, which shows that diets high in processed meat lead to 34, 000 cancer deaths per year worldwide.

【小题1】It can be inferred that the items on the Group 1 list of the IARC    .
A.are all processed foods
B.aren't often eaten by people
C.can be the most dangerous to humans
D.can greatly increase the risk of cancer
【小题2】Which can take the place of the underlined word "protest"?
A.Learn from.B.Disagree with.
C.Take interest in.D.Pay attention to.
【小题3】Which is the best title of the passage?
A.WHO: Processed Meat Can Cause Cancer
B.The Importance of Having a Balanced Diet
C.Eating Too Much Red Meat Is Bad for Humans
D.The Causes of Some Kinds of Cancer
