[单项选择]Passage Five You may a ready know that hurricanes are major tropical storms that can cause devastating waves, wind, and rain. They happen during “Hurricane Season”, which is from June lst until November 30th in the Atlantic Ocean and from May 15th until November 30th in the Pacific Ocean. A storm progresses through four different stages before it is actually considered a hurricane. First is a tropical disturbance, which has thunderstorms and rotating winds, or what scientists call cyclonic circulation. Next is a tropical depression, which is similar to a tropical disturbance, but has winds between 23 and 39 miles per hour. A tropical storm is the next level, which has stronger wind speeds between 40 and 73 miles per hour. Once winds reach 74 miles per hour, the storm is officially classified as a hurricane. The winds pick up energy from the warm surface ocean water. As a hurricane crosses over land, it begins to dissipate, or break apart and reduce in strength. This is be
A. Very heavy rain.
B. Very little wind.
C. Strong and spinning winds.
D. Strong winds and heavy rain.

[单项选择]You want to get healthy. You know you need to exercise more. But you are not ready to do intense physical activities. Don’t worry! The best thing for most of us may be to just go for n walk.
Yes, walk. At a reasonably vigorous clip (five to six kilometers per hour) for half an hour or so, maybe five or six times a week. You may not feel the benefits all at once, but the evidence suggests that over the long term, a regular walking routine can do you good.
Walking, in fact, may be the perfect exercise. For starters, it’s one of the safest things you can do with your body. It’s much easier on the knees than running and doesn’t trigger side effects.
Regular physical activity is probably as close to a magic bullet as we will come in modem medicine, If everyone were to walk briskly for 30 minutes every day, we could cut the incidence of many chronic diseases by 30 to 40 per cent.

[简答题]When you cut yourself, you bleed; you may even bleed to death if nothing is done to stop your bleeding, for your body cannot live without blood. The blood is carried in your arteries (动脉) and veins (静脉). Until doctors knew how blood moves round in the body, they could not tell accurately the different parts of the body function.

[单项选择]Passage Five Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the number 1 through 9 appear briefly at once and then tun to white squares. The player then taps the squares where the numbers had been, in order from 1 to 9. People can do it .But no human competitor has ever completed the game faster or more accurately than Ayumu the chimp. For almost five years Ayumu remains undefeated. Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp’s ability. Humphrey suspects Ayumu’s brain may have a condition that allows the chimp to see numbers as colors. This would mean that Ayumu may see a color glow after the number disappears. Then, instead of remembering the numbers, he remembers a sequence of colors, each associated with a number. The c
A. He thinks Ayumu has an amazing memory.
B. He believes that Ayumu sees the colors of numbers.
C. He was inspired by Primatologist Tetsuro Matsuzawa.
D. He delivered a speech on synesthesia at the 2011 conference.

[单项选择]Passage Five You are what you eat notwithstanding, it is only recently that most consumers have become interested in the technical details of their food’s composition, production and transport. With obesity and climate change now major concerns, and "localvore" and "food miles" entering the lexicon, shoppers are clamoring for information. And many food companies are happy to supply it, resulting in a dizzying array of multicolored labels and claims. But not everyone is happy. A proposed law in Indiana is the latest attempt in the United States to ban milk labels proclaiming that the cows from whence the milk came were not treated with recombinant bovine growth hormone (rBGH, also called recombinant bovine somatotropin or rbST). This hormone, produced by engineered bacteria, is virtually identical to the cow’s own and can increase milk production by 10-15%. There are two bad arguments for banning such labels. The f~t -- that it is impossible to determine from the milk whe
A. from the internet
B. by means of law weapons
C. from labels and claims
D. with the dictionary
