【推荐1】Nosebleeds may be annoying but they're not uncommon. Each year, up to 60 million people in the U. S. experience a bloody nose, according to Yale Medicine. The nose contains many blood vessels(血管) that help warm and humidify the air you breathe in.    1    This makes them injured easily either from dry environments, blowing your nose too hard or picking at them with your fingers. In most cases, nosebleeds aren't reason for alarm and can be effectively treated at home.

    2    

There are several ways to stop a bloody nose, but Yale Medicine suggests the following steps to stop it at home:

Sit down and firmly pinch(捏紧)the soft part of your nose just above the nostrils(鼻孔)for about 10 minutes using a tissue or towel.

Don't lean your head back.    3    This will force blood toward the tissue on your nose and help prevent blood from rolling down the back of your throat and into your stomach.

Place a cloth-covered ice pack on the bridge of your nose to tighten blood vessels and help relieve any inflammation(炎症).

Don't lie down.    4    It will help reduce blood pressure in the blood vessels in your nose and lessen the bleed.

If bleeding doesn't stop after 10 minutes of pressure, use nose drops such as Afrin.    5

D．What's the favorite way to stop a nosebleed?

E．They lie close to surface of the inside of your nose.

F．Instead lean forward and breathe through your mouth.

G．Two sprays every 10 minutes up to three times until bleeding stops.

【推荐1】Lifelong learning is the idea that learning keeps going through our daily experiences throughout our lives. It can be quite useful to us. However, to form a habit of life long learning is not easy. We need to train our brain to develop lifelong learning.     1    .

◆ Create an aim for your learning.

That may sound funny.     2    . For example, maybe your aim is to reduce your stress levels or find different ways to relax. Having an aim not only makes the learning beneficial but gives it a purpose.

◆     3    .

If lifelong learning has not been your “thing”, trying to eat this learning elephant in one bite makes it more difficult to stick with it.     4    . For example, instead of struggling to read 100 pages in a book every day, why not start with 15 minutes, two or three times a week? After you have made that small habit into place, you can then add to it.

◆ Make it fun.

    5    , the act of doing it obviously decreases. Have some fun with your learning. For example, for every new learning opportunity you take, give yourself some reward. Give yourself a gold star. Make learning a game. Whatever is going to make learning fun for you, make sure that you experience the fun!

A．Start small

B．Be creative

C．But having an aim in mind truly does help a lot

D．That must be meaningful

E．If learning is a chore or becomes a chore

F．Here are some simple ways to help you

G．Breaking down the learning into bite-sized pieces helps.

【推荐2】In my time here at Carleton College, I’ve picked up many valuable pieces of advice from others, and have come up with a few of my own. With my time here drawing to a close, here’s two of the most valuable ones I wish I had known as a freshman .

First, don’t expect to join all the clubs here. Taking part in them is good, but the workload here is too heavy and time with your friends is too limited to devote yourself to a million and one clubs. Find a couple of things you dig, and you’ll find yourself much happier than if you had spent your time joining every single organization that sounds somewhat interesting to you. Also, don’t always think of your free time in terms of organizations you can join. Getting really good at something - an instrument, creative writing, cooking - is just as good a use of your free time, even if it might never be taken into any resume(简历).

Second, when Socrates said “Know Yourself”, he was talking about your sleep schedule. You can fool yourself into thinking that an 8:30 a. m. class in the winter is the perfect way to get your day started, but you soon may find yourself emailing the teacher with excuses for being absent. Scheduling all your classes afternoon is sometimes equally deadly; you might just end up going out the night before knowing you can safely sleep in. I’ve found that the way to take classes is to load them in the middle of the day; nothing before 9:50 a. m., nothing after 3:10 p. m.

1. Who is probably the author of the text?

A．A school headmaster.	B．A graduating student.

3. What does the author suggest doing in one's free time at college?

A．Getting apart-time job.

B．Join clubs that seem interesting.

C．Take up a few hobbies.

D．Prepare a resume as early as possible.

4. What is the best t me for taking classes according to the author?

A．In the evening.	B．In the afternoon.
C．From8：30a.m.to9：50a.m..	D．From9：50a.m.to3：10p.m..

【推荐3】While Jennifer was at home taking an online exam for her business law class, a monitor a few hundred miles away was watching her every move.

Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked－remotely－to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?

In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid—that students haven’t just searched the Internet to get the right answers.

Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of “open online courses.” Private colleges, public universities and corporations are jumping into the online education field. spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.

Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.

Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.
