Spring is here and so is the cycling season. Here are some tips on how to do it safely and comfortably.
Watch your feet—Pushing with the wrong part of the foot can raise your risk of developing a painful injury of the heel and arch（脚心）, says Rob Werstine, a sports physiotherapist（理疗师）and board member of the Canadian Physiotherapy Association. You should push with the ball of your foot, he says.
Layer up—While it’s still cool, wear layers of clothing, with clothing close to the body that breathes and outer layers that do not absorb water. Go for bright colors that increase your visibility（可见度）.
Be reasonable—If you are just starting out and aren’t in good shape, don’t sign up for a 50-kilometre ride. And while cycling is great exercise for people who want to get into shape, if your doctor advises you not to do tiring exercise, cycling shouldn't be your starting position, Werstine says. Walk to begin getting into shape and then graduate to cycling.
Fix the fit—If you develop lower back pain or numbness in your hands and fingers from cycling, it could be your bike isn’t adjusted properly for your height. A good cycle shop can help you find the right height for the seat and handlebars, but if you have continuing problems, consider consulting a bike fit physiotherapist, Werstine says.
Be mindful—You have to pay attention on the roads to vehicles, other cyclists and pedestrians（行人）.Consider taking a cycling safety course to practise your skills. Or do some reading about how to avoid dangerous cycling situations. bicyclesafe.com, for instance, lists 10 types of car-bike accidents and how to avoid them.

RIDING in school buses in the early morning，then sitting in poorly lit classrooms，are the main reasons students have trouble getting to sleep at night，according to new research．
Teenagers，like everyone else，need bright light in the morning to allow their circadian rhythms(生理节奏)to get into step with nature's cycles of day and night．
If they don't get blue 1ight in the morning，they get to sleep an average of six minutes later at night，until their bodies are completely out of sync(同步) with the school day，researchers from Rensselaer Polytechnic Institute in New York said last month．
The finding was made by fitting goggles(护目镜)that block blue light from the sun to a group of students．The researchers discovered that their circadian rhythms were greatly affected．
Parents and teachers have been complaining in recent years that teens stay up too late at night，then fall asleep in class the next morning and do poorly in school．The new findings provide a possible explanation for the problem．
At the root of the research is the circadian rhythm, the body's natural sleep and waking cycle．Even though the Earth makes a full rotation(旋转)in 24 hours，the body's circadian cycle is about 24 hours and six minutes 1ong．The cycle is mediated(调节)by a chemical called melatonin(褪黑激素)．The body starts to produce it about two hours before it is time to sleep and, in the absence of blue 1ight，the body produces about six minutes later each day.
In the study, the researchers studied 11 students at Smith Middle School in New York, which was designed so that a lot of sunlight reaches classrooms．
On a Friday night，the researchers measured what time the 11 students’ bodies began releasing melatonin．On Monday morning，the students were sent to school with orange goggles that blocked most blue light from their eyes to mimic(模拟) the conditions found in many---if not most--schools．
By the end of the week，the students were releasing melatonin 30 minutes 1ater in the evening---an average of six minutes a day--and going to sleep correspondingly(相应的) later．
“This is our first field study，”said lead author Mariana G．Figueiro．He said they would like to repeat it in larger studies and for longer periods of time。
If the findings are repeated，a variety of solutions are available．Ideally, new schools would be built to allow more natural sunlight into the classrooms．Students could also be exposed to more sunlight outside．
68. According to the findings related in this article, many teenagers stay up late because_______
A. they lack melatonin in their bodies
B. they have to get up so early to catch the school bus
C. their circadian rhythms are in disorder
D. they do not get enough blue light in the morning
69. According to the findings, a student who normally slept at 10:00 pm, but who spent 10 days in a poorly lit classroom, would probably be falling asleep at___________after the period.
A. 12:00pm B. 11:30pm C. 11:00pm D. 10:00pm
70. What does the article tell us?
A. Unlike adults, teenagers tend to feel sleepy during daytime.
B. The sunlight is the only thing that can affect our circadian rhythms.
C. If the findings prove correct, solutions could be found to teen sleeping problems.
D. Most schools have small windows and the classrooms are poorly lit.
71. The main point of the article is to___________
A. warn teenagers not to stay up late or sleep in class
B. report on some new findings related to teenagers' sleeping problems
C. give suggestions on how to build schools
D. advertise goggles which can protect the eyes from the sun

New technology links the world as never before. Our planet has shrunk（收缩）. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communication’s equipment is greatly enhanced by foreign language skills.
Deeply involved with this new technology is a breed of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic(国内的) business efforts.
Overseas assignments are becoming increasingly important to advancement within executive(行政的) ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superior will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.
Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets.
English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate(候选人) the edge when other qualifications appear to be equal.
The employee posted abroad who speaks the country’s principal language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients(客户) over the telephone or by fax machine is an obvious asset to the firm.
65. What is the author’s attitude toward high-tech communications equipment?
A. Critical.                   B. Indifferent.               C. Negative.                 D. Positive.
66. With the increased use of high-tech communications equipment, business people_________.
A. have to get familiar with modern technology
B. are gaining more economic benefits from domestic operations
C. are placing more importance on their overseas business
D. are eager to work overseas
67. In this passage, “out of sight and out of mind” (Para. 3) probably means _________.
A. being unable to think properly for lack of insight
B. being totally out of touch with business at home
C. missing opportunities for promotion when abroad
D. leaving all care and worry behind
68. According to the passage, what is an important consideration of international corporations in employing people today?
A. Connections with businesses overseas.     B. Ability to speak the client’s language.
C. Technical know-how.                                   D. Business experience.

If you have ever been rock climbing, then you will know that it is not a very easy sport. In fact you probably felt quite defeated when you first tried to do any serious climbing. Indoor and outdoor rock climbing are both extremely demanding and, like anything else, require practice, to get good at. What most people don’t know is that the sport of rock climbing is one of the most physically and mentally demanding sports there is.
There are three basic types of rock climbing. Top roping is probably one of the most common types and is basically climbing with a partner. The second type, which is very similar to top roping, is called lead climbing. In both of these types of rock climbing the climber can sit off the wall and rest on the rope.
The third type of rock climbing is called bouldering. Bouldering is a type of free climbing without any ropes. This is the most demanding of all climbing types. The climber must be able to complete the climbing without taking a rest on the rope.
Believe it or not, climbing is said to be about 75% legs and only 25% arms. To climb efficiently and successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to always have three points touching the wall, whether it is both feet and one hand, or one foot and both hands, as it is much easier to have your weight rest on three points than on two. Another important idea to grasp is that your arms in most cases will do the climbing; they only hold you into the wall so that your legs are actually pushing you upward. Also, the closer you are to the wall, the easier it is to climb.
Rock climbing may sound a bit too extreme for the everyday person but it really is an amazing workout. Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems. The great thing about rock climbing is that it is mentally challenging as well. You are constantly analyzing the way your body moves and how to do certain moves on the wall. For anyone who wants to get into shape, rock climbing is a fun and effective way to exercise muscles.
41．What does the author think of rock climbing?
A．It is an easy sport.          B．It is challenging.
C．It is quite dangerous.       D．It is extremely difficult.
42．According to this passage, we know that __________.
A．indoor rock climbing is much easier than outdoor rock climbing

43．It is much easier for a rock climber if he ___________ while climbing.
A．takes a rope            B．has a partner
C．has three points touching the wall   D．uses feet more often

A．Keeping the body closer to the wall   B．Resting more often on the arms
