【题目】 Do you look happy? angry? Have you ever wondered how you know what another person’s mood is just by looking at his or her face? Studies have shown that one instantaneously (瞬间地) and subconsciously makes a determination of another person’s mood just by glancing at the position and appearance of both the eyebrows and mouth. But what if only the position of the eyebrows was varied , and not the mouth? Would you still be able to determine his or her mood or personality just by seeing the eyebrows?

Observe the four faces shown below. Notice how each face has exactly the same shape. the same smile, and the same eyes. The only difference between each of the faces is the position of the eyebrows.

Low, flat eyebrows that hang over the eyes indicate tiredness, while an eyebrow that is highest in the middle denotes sadness. Downward slanting eyebrows show anger, while highly arched eyebrows show happiness.

Frequently, malposition of the eyebrows, such as eyebrow sagging(下垂) and upper eyelid fullness, can be overlooked when considering facial aging and expression. Furthermore, the heavy eyebrow skin pushed the eyelid down causing a tired appearance.

To avoid eyebrow sagging, many people raise their eyebrows to remove the brow and eyelid skin from their visual space. These people eventually develop wrinkles in the forehead due to the constant movement of the muscles that raise the eyebrow. In addition, there are those who are sensitive to light and frequently’ squint(斜视) and squeeze’ their eyes. This effectively pulls the eyebrows down and leads to wrinkles between the eyebrows and at the corners of the eyes.

Botox is an effective measure for fine lines of the forehead and lines between the eyebrows. Botox works by freezing the muscle movement for several months. For the purpose of creating a more pleasant appearance, the best corrective measure is brow-lift surgery.

A.An advertisementB.A magazine article

C.A business reportD.A scientific report

【2】A person’s eyebrows that hang over the eyes low and flat can cause a(n) _____appearance.

B.To arouse people’s interest in the best way of removing wrinkles in the forehead and between the eyebrows.

C.To explain what leads to wrinkles in the forehead and near the eyebrow.

【题目】Directions：Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

Tributes（致哀）poured in last week to the world-famous British physicist Stephen Hawking, whose insights 【1】 modern cosmology（宇宙学）and inspired global audiences in the millions. He died at the age of 76 on March 14.

Hawking was given only a few years to live after being diagnosed with ALS（肌萎缩性脊髓侧索硬化症）at the age of 21. The illness left him in a wheelchair and largely 【2】 to speak expect through a voice synthesizer（合成器）. Nevertheless, Hawking completed his doctorate（博士学位）on the origins of the universe three years later and became a research fellow at the University of Cambridge’s Caius College.

Hawking’s first major 【3】 came in 1970. With mathematician Roger Penrose, Hawking used Einstein’s theory of relativity（相对论）to 【4】 the origins of time and space to singularity（奇点），a single point of zero size and infinite density（无限大的密度）where all the laws of physics would have broken down. Their work gave mathematical expression to the Big Bang theory（创世大爆炸理论）. Hawking was the first to try to 【5】 relativity with quantum mechanics（量子力学）. In 1974, he put forward that black holes leaked radiation, now known as“Hawking radiation,”and would eventually disappear with a tremendous explosion. The proposal 【6】 to one of the most passionate debates in modern cosmology—before Hawking, it was widely accepted that black holes were completely black and would 【7】 forever.

In 1982, Hawking was among the first to show how tiny changes in the distribution（分布）of matter might give rise to the 【8】 of galaxies（银河系）in the universe and lay the seeds of stars, planets and life as we know it.

For 30 years, Hawking was Cambridge’s Lucasian professor of mathematics（卢卡斯数学教授席位），arguably Britain’s most distinguished chair（席位）and a post once held by Sir Isaac Newton. He received 12 honorary degrees and was awarded a Companion of Honor（英国荣誉勋位）by Queen Elizabeth in 1989. The 1988 publication of A Brief History of Time won Hawking international 【9】. The book, through which the professor brought complex science to a【10】 audience, has sold at least ten million books in 40 languages.

Qi Baishi （1863-1957）was one of China’s greatest painter. He worked with wood during her early youth. Then between 1902 or 1909, he travelled across the country and paint many pictures of scenery. Late, his interest changed later to simple pictures from everyday life, such as vegetables, flowers, birds, and insects. Cabbage is well-known example of Qi’s works. The tiny insect near the cabbage had some red on its back. Its black eyes, that are fixed on the cabbage, show the creature’s interest on the vegetable. Qi Baishi’s style of painting often leave the audience guessing and makes them to use their imagination.

【题目】 Communicating effectively means more than knowing what to say and when to say it. Communication involves the subtle signals your body language sends to those who are watching. Here are some common body actions and the impressions they create:

● Fiddling (好动) — Playing with your watch or a pen looks like you’re bored or impatient.

● Clock watching — It looks like you’re to move on to something else.

● Tapping — Tapping your feet or fingers suggests you are impatient or nervous.

● Staring — An unblinking (不眨眼的) stare conveys threatening or violent behaviour.

● Legs crossed or body hunched (弓背，耸肩) — Closing up your body profile — becoming smaller — looks like you lack confidence.

● Arms crossed — If you keep your arms folded during communication, you appear to be defending yourself against the others.

● Touching your face — When you have your hand in front of your mouth, you appear very shy.

● Rubbing your nose, looking away — People who are lying often rub their nose or look away when speaking.

● No eye contact — If you won’t look the other speaker in the eye, you seem to have low interest or a lack of confidence. (Don’t forget staring above.)

How you communicate with your body language is just as important as what you say. Watch your body language and control the unconscious messages you might be sending.

【1】According to the passage, effective communication includes all of the following EXCEPT _____.

A.knowing what to say

B.sending unconscious messages to other people

C.saying the right thing at the right time

D.getting information from the other speaker’s body language

【2】Which of the following people looks shy according to the passage?

A.B.
