The human nose is an underestimated tool. Humans are often thought to be  1___ smellers compared with animals, but this is largely because, unlike animals, we stand upright. This means that our noses are  2  to detecting those smells which float through the air,  3  the majority of smells which stick to surfaces. In fact though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of  4  human smells even when these are  5  to far below one part in one million.

　　  6     , some people find that they can smell one type of flower but not another, while others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate  7     smell receptors in the nose. These receptors are the cells which sense smells and send  8    to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when  9     to it often enough.

　　The  10   for insensitivity to smell seems to be that brain finds it  11    to keep all smell receptors working all the time but can  12   new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not  13     of the usual smell of our own house but we  14     new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15    for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.

What time is it? Most people are pretty accurate in their answer. And if you don’t know for sure, it’s a very likely that you can find out. There may be a watch on your wrist, there may be a clock on the wall, desk, or computer screen; or maybe you’re riding in a car that has a clock in the dashboard (仪表板).

Even if you don’t have a timepiece of some sort nearby, your body keeps its own beat. Humans have an internal clock that regulates (调节) the beating of our heart, the pace of our breathing, the discharge (排出) of chemicals within our bloodstream, and many other bodily functions.

Time is something from which we can’t escape. Even if we ignore it, it’s still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our ally.

By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you’ll have to spend on your outside interests.

The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.

The underlined word “ally” in Para. 3 more likely means somebody or something that is _________.

   A. your slave and serves you  

B. your supporter and helps you

   C. under your control and obeys you     

D. under your influence and follows you

The author intends to tell us that time _____________.

   A. could be regulated by a timepiece such as a clock or a watch

   B. could be managed by the internal clock of human bodies

   C. should be well managed for our own interest

   D. should be saved for outside interests

In the next part, the author would most probably discuss with you ________.

   A. how to keep up with the times       B. how to make up for lost time

   C. how to have a good time     D. how to make good use of time

“If you run for more than five minutes at any time, you might need a pair of running shoes,” advises Stephen Pribut, a US sports medicine expert. Running shoes are highly technical footwear. They provide stability（牢固）while bearing up to three times the wearer’s body weight. But it’s not easy to find the right pair. Finding the right running shoes is something of an art, or a science and a feel.

The science part begins with the shape of the arch（弓）of your foot, which anyone can find out at home with this quick experiment: Put your foot in water and place it on a piece of brown paper. If you see a “C” shape on the paper when you remove your foot, you have a rare high arch. If the shape looks more like a rectangle, that means you have flat feet. See something in between? That’s a normal arch.

Conveniently for shoppers, shoe companies nowadays divide their shoes in three categories: neutral(for high arches), stability(for normal or low arches) and motion control(for flat arches). So you will know which type suits you.

At this point, most people would just grab an appealing shoe and try it on. But professionals would do a few quality-control tests. First, you bend the shoe toe to heel to see where it bends. If it’s not at the forefoot---where the foot actually bends, be afraid. Then you grip both ends and twist in opposite directions. If you can twist it like a towel, it means there’s zero support. Finally, you squeeze(挤)the heel in both directions. A stable heel won’t cave in.

Now you need to check the mold(模子)that shapes the inside of the shoe: whether it’s wide or narrow in the mid-foot, how it sits on the heel and how roomy the toe box is.

It’s wise to hold off until the afternoon to make the shoe purchase, to allow for any swelling(肿胀) that your feet do throughout the day. Toes also decide sizing choice. The rule is you need a finger’s width from your longest toe (whether that’s your big one or not) to the end of the shoe.

What is the main idea of this passage?

    A．Advantages of wearing running shoes fitting you.

    B．Ways to get to know about the shape of the arch of your foot.

    C．Advice on how to choose the right pair of running shoes.

    D．Best time to buy a pair of running shoes.

If the arch of your foot looks like a “C” shape, you have _________.

    A．a normal arch    B．a high arch C．a flat arch D．a low arch

．The underlined phrase “cave in” most probably means ______.

    A．bend     B．stretch C．shake    D．crash

．Why is the late afternoon the ideal time to go shopping for shoes?

    A．We are likely to be more patient in the afternoon.

    B．Feet usually become large late in the day.

    C．The toes become longer late in the day.

    D．The arch of our feet will be in best shape in the afternoon.

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent camera team out one evening to film the sunset for him.

 The next morning he said to the men, “Have you provided me with that sunset?”

 “No, Sir,” the men answered.

The director was angry.  “Why not?”  he asked.

“Well,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”

“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”

But then a young secretary had an idea. “Why don’t you photograph a sunrise,” she suggested, “and then play it backwards, Then it’ll look like a sunset.” “That’s a very good idea!” the director said. Then he turned to the camera team and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”

The camera team went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, Sir,” they said, and give it to him. He was very pleased.

They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the sunset behind them.”
