阅读理解:According to astronomer S.A. Phinney, kicking a rock hard enough to free it f

rom Earth's gravity would require a meteorite capable of making a crater more than 60 miles across.

Moreover, even if Earth rocks were freed by meteorite impact, Mars's orbit is much larger than Earth's, so Phinney estimates that the probability of these rocks hitting Mars is about one-tenth as great as that of Mars's rocks hitting Earth.

To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions.

He found that 17 of the 1,000 particles would hit Mars.

1.Which of the following, if true, would cast most doubt on Phinney's estimate of the probability of Earth rocks hitting Mars?

A Rather than going in random directions, about 25 percent of all particles ejected from Earth go in the same direction into space.

B Approximately 100 meteorites large enough to make a noticeable crater hit the Earth each year.

C No rocks of Earth origin have been detected on Mars.

D The velocity of rocks escaping from Earth's gravity is lower than the velocity of meteorites hitting the Earth.

E No craters more than 60 miles across have been found on Mars.

阅读理解:阅读下面的短文,根据文章内容从A、B、C三个选项中选出一个最佳选项。

Stress around interviews is often influenced by our assumptions we make to ourselves about the process. Countering anxiety-provoking thoughts can help to lower levels of anxiety. “I just messed up that answer, and there’s no hope.” One poor answer normally does not knock a candidate out of consideration. An interview is like a test, getting an 85 or 90 might be good enough to get the job.

Visualizing success can improve performance and help ease anxiety. Always try imagining positive interactions with your interviewer, particularly in the hours just before your interview.

To some extent, relaxation techniques, such as progressive muscle relaxation or breathing exercises, can manage anxiety. If your anxiety around interview is excessive, you might consider seeing a doctor to develop effective countermeasures.

Reading Comprehension(阅读理解) Passage 4 Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you. Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to identify the criminal. Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands. When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away. Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌) a surface just by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool. 根据短文完成1-5题,在空格处填写正确选项的字母。 1. According to the passage,_______ could be used to identify the criminal. A. fingerprints B. scientists' hands C. microbes D. fingerprints and microbes on people's hands

阅读理解:阅读下面的短文,根据文章内容进行判断,正确写“T”错误写“F”。Cross training is traini

阅读理解:阅读下面的短文,根据文章内容进行判断,正确写“T”错误写“F”。

Cross training is training an employee to do a different part of the organization's work. Training worker A to do the task that worker B does and training B to do A’s task is cross training. Cross training is good for managers because it provides more flexibility in managing the workforce to get the job done. On the other hand, cross training has some benefits for the employees as well. It lets them learn new skills, makes them more valuable, keeps them stimulated and reduces worker boredom.

Cross training can be used in almost any position in almost any industry.I cross trained some of my design engineers to go on field installation trips and get first hand knowledge of how their designs worked, or didn’t work, in the field. Cashiers can be trained to stock shelves and stockers trained to cashier. This allows you to quickly open additional registers if the customer queue gets too long.

As you prepare cross training plans, you need to consider both the company benefits and the employee benefits. Carefullyselect the employees to be cross trained. Some people like to learn new things. Some are more comfortable sticking to what they know. Don’t decide which employees are ready for a change based on their age or performance.

1. Cross training is training an employee to do a different job in a different company. {T、F}

2. Cross training is beneficial not only for managers but also for employees.{T、F}

3. Cross training can apply to almost any position and almost any industry.{T、F}

4. Not all employees are suitable to be cross trained.{T、F}

5. You can decide which employees to be cross trained according to their age.{T、F}

阅读理解题为6-10题,请按顺序作答。 阅读理解: Directions:Read the following passages carefully. Each passage is followed by some questions or unfinished sentences. For each of them there are four choices marked A, B, C, and D. Choose the best answer to each question.   Everybody lies. It may only be “white lies”, but everyone tells lies or “omits the truth” sometimes. People start lying at around age 4 to 5 when children gain an awareness of the use and power of language. This first lying is not ill-natured, but rather to find out, or test, what can be controlled in a child’s environment. Eventually children begin to use lying to get out of trouble or get something they want. White lies, those told to protect someone’s feelings, are not a big deal at all. The person, however, who seems to feel forced to lie about both small and large stuff, has a problem. They lie to protect themselves, look good, gain financially or socially and avoid punishment. A much more troubling group is those who lie a lot, and knowingly, for personal gain. Lying often gets worse with the passage of time. When you get away with a lie, it often forces you to continue your lies.   Why do we dislike liars so much? It’s a matter of trust. When people lie, they have broken a bond – an unspoken agreement to treat others as we would like to be treated. Serious lying often makes it impossible for us to trust another person again. Because the issue (问题) of trust is at risk, coming clean about the lie as soon as possible is the best way to mend fences. If the truth only comes out once it is forced, repair of trust is far less likely. As a parent, the most important message you can send to your children about lying is that you always – always – want them to come clean with you. No matter how small a lie they have told, remind them that you would always rather hear the truth, no matter how bad it is, than be cheated. Tell them there is really nothing better in your relationship than your trust of each other. According to the passage, the worst liars are those who ________.

A、tell white lies

B、feel forced to tell lies

C、lie a lot for personal gain

D、began to lie at a very young age

ORGANIZATION STRUCTURE IN HOOGLE ENGINEERING

I'm Michael Bush, Managing Director of Hoogle Engineering. I am pleased to welcome you here to our website and I'd like to tell you a little about the company and its organization. Hoogle Engineering was set up in 1960. It was divided into several departments at that time, such as the sales department, marketing department, and production department. Lots of managers were employed to manage it all.

Fortunately things are different now. Sixty people are employed by Hoogle and communication between departments is considered to be one of the most important aspects of the business. The market is global so we need to make contact with customers worldwide, not just locally.

But in the old days we were all in different departments and never spoke to each other. We had a tall structure. Traditionally we had people at the first level on the shop floor, manufacturing products according to the instructions which they were given. Then you had a supervisory level of people who supervised them every day. Then you moved up to the middle management, who were doing the tasks of getting new business, and then you had the senior management team, and then you had the board, who decided the business strategy. So there were a lot of levels in the company in the old days actually.

The structure today is that we form. teams within teams to place people who can manufacture a product. Each team has members that can manufacture different products. The actual teams now are self-managing, so we don't even have team leaders. You've got the teams, and then you've got two people, only two people, who are what you think of as management. This is generally called flat structure.

Juvenile Delinquency refers to criminal acts committed by children or teenagers, specifically anyone below the age of eighteen. These crimes hurt society and the children themselves.

There are many factors that cause juvenile delinquency.

Some children want to test their parents' or society's limits. Sometimes juvenile crimes happen because of a lack of rules and supervision. For example, many times children commit crimes after school and while their parents are at work.

Additionally, mental illness and substance abuse are main factors. 15-20% of juveniles convicted of crimes have serious mental illnesses, when the range of mental illnesses widens,the percentages increase to 30-90%.

Also, many people believe, a child's environment and family are greatly related to their juvenile delinquency record. For example, the dynamics of a family can affect a child's delinquency rate.

Poverty level is another factor.

Finally, another cause could be the relationships a child grows in school or outside of school. A positive or negative friendship can influence the chances of children becoming delinquents. Peer pressure is also at play. Relationships and friendships can lead to gangs, these are major factors in violent crimes among teens.

These are just some of the causes of juvenile delinquency.

操作提示:正确选T,错误选F。

1. Juvenile Delinquency hurts the children themselves only. {T; F}

2. There are five reasons for juvenile delinquency according to the text.{T; F}

阅读理解:阅读下面的短文,根据文章内容从A、B、C三个选项中选出一个最佳选项。High-speed rail is

阅读理解:阅读下面的短文,根据文章内容从A、B、C三个选项中选出一个最佳选项。

High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250 km/hr and existing lines in excess of 200 km/hr are widely considered to be high-speed, with some extending the definition to include much lower speeds (e.g. 160 km/hr) in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.

Many countries have developed high-speed rail to connect major cities, including Austria , Belgium, China, France, Germany, Italy, Japan, Poland, Portugal, Russia, South Korea, Sweden, Taiwan, turkey, United Kingdom, United States and Uzbekistan. Only in Europe does HSR cross international borders. China has 16,000 km of HSR, accounting for 60 percent of the world’s total. While high-speed rail is usually designed for passenger travel, some high-speed systems also offer freight service.
