When movie star Scarlett Johansson was photographed naming in Los Angeles recently, she attracted a lot of attention; for the 27-year-old actress was wearing Vibram FiveFingers, so called because they look more like gloves than shoes, with a space for each toe.

Strange though they may look, these so-called barefoot shoes, which reproduce the effect of barefoot running but with less pain, are just one brand in a range of minimalist footwear. These super-thin sports shoes are causing a stir in the world of running and fitness. Why? Because some experts believe they could make you a better, more efficient runner and that traditional trainers could be doing you more harm than good.

"Wearing a shoe that has lots of cushioning and support affects the way your body naturally moves and studies suggest that this carries a higher risk of injury," explains Matt Wallden, an athlete performance expert. "But with barefoot shoes, the foot can actually feel the firmness and shape of the ground, which allows your body to respond effectively.'"

But before you rush out to invest in minimalist footwear, be careful. These kinds of shoes are not meant for everyone, or at least not straight away.

"Ordinary sports shoes with support are good for beginners whose bodies are not used to the impact of running," explains Patrick Davoren, former Olympic athlete. "It you are not in great condition, then running in minimalist footwear may cause injuries and will turn a lot of people off exercise and running.

If you are currently injured, and figures show that in any given year 65% of all runners are, it can be tempting to try anything that promises to get you back on the road, trail, or beach. But barefoot running is not a method of treating injury nor is it a magical way of suddenly turning you into a great athlete.

Even if you're used to running, when you start using minimalist shoes you should build up your distance gradually. Start_off'by doing just 10% of what you'd normally run and increase the distance by no more than 10% every week. And a word of warning - you may never have soft feet again

1.The Vibram FiveFingers are shoes ______.

A. specifically designed for women

B. that have lots of cushion inside

C. safest for people who enjoy sports

D. that are much thinner than normal sports shoes

2.The underlined word "they" in paragraph 2 refers to ________.

A. experts B. feet C. shoes D. runners

3.According to Matt Wallden, the new shoes ________.

A. make feet more sensitive to the running surface

B. will produce immediate improvements

C. force your body to move less naturally

D. increase the chances of getting hurt

4.The author suggests that new users of Vibram FiveFingers should ________.

A. run in the shoes every day at top speed

B. begin with a shorter running distance than normal

C. occasionally run barefooted to harden their feet

D. make sure they are already very fit before using them

5.Where would you probably read this article?

A. A travel book.            B. A movie website.

C. A sports magazine.        D. A science journal.

Chinese female scientist Tu Youyou won the 2015 Nobel Prize in medicine on October 5 for her discoveries concerning a novel treatment against Malaria（疟疾）. This is the first Nobel Prize given to a Chinese scientist for work carried out within China.

Tu shared the prize with Irish-born William Campbell and Satoshi Omura of Japan, who were honored for their revolutionary anti-roundworm treatment. 84-year-old Tu is awarded this prize for her contribution to cutting the death rate of malaria, reducing patients’ suffering and promoting mankind’s health. Although she received several medical awards in the past, the 2015 Nobel Prize is definitely the most privilege reward that recognizes Tu’s dedication and perseverance in discovering artemisinin（青蒿素）, the key drug that battles malaria-friendly parasites（寄生虫）.

However, her route to the honor has been anything but traditional. She won the Nobel Prize for medicine, but she doesn’t have a medical degree or a PhD. In China, she is even being called the “three-noes” winner: no medical degree, no doctorate, and she’s never worked overseas. No wonder her success has stirred China’s national pride and helped promote confidence of native Chinese scientists.

The fact that Tu has none of these three backgrounds reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one dives into scientific research. There have been discussions on people who really love science but are never able to achieve much during their whole life. Their contributions can never be ignored. They work so hard to prove the wrong way so that the future researchers will be closer to the right one.

As the first Chinese mainland Nobel Prize Winner of natural science award, Tu’s record-breaking winning also serves as a reminder to those who are too eager for instant success. Science is never about instant success. Tu spent decades on scientific research before its value is officially acknowledged. There is no way to measure how much one devotes to science and compare it with how much reward he or she may get.

1.It can be concluded from the text that __________.

A. Tu worked home and abroad to conduct her research

B. Tu got the Nobel Prize for her anti-roundworm treatment

C. The Nobel Prize is the first award to recognize her work

D. Her discovery of artemisinin has helped to cut Malaria death rate

2.The author seems to agree that a person who is more likely to become a scientist is the one with__________.

A. a sense of national pride

B. relevant academic knowledge

C. enthusiasm for scientific research

D. a desire to achieve success

3.In writing the passage, the author intends to ___________.

A. remind readers of the principles of scientific research

B. discourage the pursuit of instant success in science

C. inform readers of the news and make comments

D. praise the award winner and encourage scientific research

Scientists are debating how to limit their newly-discovered power to change genetic structure (结构). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物种) of plants and animals that are damaging to other species.

In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (释放) into the wild.

Sixteen biologists, ethicists (伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

【小题１】What possible advantage does gene control in wild animals and plants have?

A. Changing the Zika virus permanently.

B. Getting rid of damaging species forever.

C. Having the changed genes in their next generations.

D. Making all the species more productive and stronger.

【小题２】As for genetically changed wild animals and plants, what are scientists worried about?

A. They may become weaker or die out.

B. They may be more productive than before.

C. They may cause damage to their living habitat.

D. Their genes may spread to later generations.

【小题３】Which of the following is true according to the passage?

A. Scientists are certain what exact results gene modification leads to.

B. Gene modification can benefit some farm animals and agricultural plants.

C. Scientists won't modify any genes before they make the final decision.

D. Gene modification will be encouraged in more creatures in the near future.

【小题４】The article is mainly intended to ________.

A. appeal against research on gene control

B. show how to change genetic structure

C. inform us of power and danger of gene control

D. give the reason why gene modification is necessary

Life may have evolved on at least three planets within a newly discovered solar system 39 light years from Earth. Astronomers at the NASA have discovered no less than seven roughly Earth-sized worlds orbiting a dwarf star in the system. Scientists had previously identified a tiny number of "exoplanets", which are believed to have the qualities needed to support life. However, the new system contains an unprecedented(前所未有) number of Earth-sized, probably rocky planets, and is being acknowledged as an "accelerated leap forward" in the search for　 extraterrestrial (外星球的)life.

Three of the new planets are said to be particularly promising because there might exist oceans. Thomas Zurbuchen, associate administrator of NASA, told a press conference in Washington: "This gives us a hint that finding a second Earth is not a matter of 'if', but 'when'."

The planets were discovered using NASA's Spitzer Space Telescope, which was able to track how fast each of the planets crossed the star Trappist-l and completed an orbit. From this the　 research team calculated how far the planets were from their star, and therefore how likely they are to be habitable.

NASA's Hubble Space Telescope is already being used to search for atmospheres around the planets. Future telescopes, including the proposed European Extremely Large Telescope and the James Webb Space Telescope, may be powerful enough to discover markers of life, such as oxygen in the atmospheres of exoplanets.

Astronomers believe there could be as many as 40 billion potentially habitable worlds in our galaxy, the Milky Way. Prof Zurbuchen said that now was a "gold-rush phase" in the search for these exoplanets.

1.What makes the new discovery significant?

A. Ample markers of life.　　 B. The potential to support life.

C. Great distance from Earth.　　 D. The search for extraterrestrial life.

2.What helps explore atmospheres around the exoplanets?

A. Spitzer Space Telescope.　　 B. Hubble Space Telescope.

C. European Extremely Large Telescope.　　 D. James Webb Space Telescope.

3.What may be the best title for the text?

A. New Solar System Found　　 B. Second Earth Discovered

C. Why to Explore Outer Space　　 D. Gold-Rush Stage to Come
