Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods.

Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers.

Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. So unless the government has a good system of control, or can educate the people, the forests slowly disappear.

This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are no trees, the rainfalls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich top soil in which crops grow. When all the top soil is gone, nothing remains but worthless desert.

1.Trees are useful to man mainly in three ways, the most important of which is that they can    ________.

A. keep him from the hot sunshine    B. protect him from droughts and floods

C. make him draw quick profit from them    D. enable him to build warships

2.It’s a great pity that ________.

A. man hasn’t realized the importance of trees to him

B. man is eager to profit from trees

C. man is only interested in building empires

D. man hasn’t found out that he has lost all trees

3.Sooner or later the forests will disappear ________.

A. unless a country has a plenty supply of trees

B. unless people stop cutting down their trees

C. unless the government punishes those who cut trees instead of planting them

D. unless all people are taught the importance of planting trees

4.The word “bind” in Paragraph 5 means “________”.

A. to wash away    B. to make stay together

C. to make wet    D. to improve

 

1. B 2. A 3. D 4. B 【解析】 这是一篇说明文。这篇短文从三个方面告诉我们树对人类来说是重要的。一是树可以为人类和动物提供食物、木材和其他产品;二是树可以给人类提供树荫;三是树木可以防止干旱和洪水。因此我们要多植树,注意保护树木。 1.推理判断题。答案定位在第一段Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods.(树木对人类有三个非常重要的作用:它们为人类提供木材和其他产品;它们给他遮荫;它们有助于防止干旱和洪水。)以及第二段Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important.(不幸的是,在世界上许多地方,人类还没有意识到第三种服务是最重要的。)由此可知,树对人类的用处主要有三方面,其中最重要的是它们能保护人类免受干旱和洪水,故选B。 2.细节理解题。答案定位在第二段Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important.可知很遗憾的是,人类没有意识到树木对他们的重要性,故选A。 3.细节理解题。答案定位在第四段So unless the government has a good system of control, or can educate the people, the forests slowly disappear.可知除非所有人都被教导植树的重要性,否则森林迟早会消失,故选D。 4.词义猜测题。下文This prevents the soil from being washed away.意思是这可以防止土壤被冲走。由此推断出上文的意思是因为有树的地方,它们的根会把土壤弄碎,让雨水渗入,也会把土壤凝固在一起。“bind”的意思是凝固,故选B。

Sales Strategies

How can a company improve its sales? One of the keys to more effective selling is for a company to first decide on its “sales strategy”. In other words, what is the role of the salesperson? Is the salesperson’s job narrative, suggestive, or consultive?

The “narrative” sales strategy depends on the salesperson moving quickly into a standard sales presentation. His or her pitch highlights the benefit for the customer of a particular product or service. This approach is most effective for customers whose buying motives are basically the same and is also well suited to companies who have a large number of prospects on which to call.

The “suggestive” approach is tailored more for the individual customer. The salesperson must be in a position to offer alternative recommendations that meet a particular customer’s needs. One key aspect of the suggestive approach is the need for the salesperson to engage the buyer in some sort of discussion. The salesperson can then use the information from the customer to suggest an appropriate product or service.

The final strategy demands that a company’s sales staff act as “consultants” for the buyer. In this role, the salesperson must acquire a great deal of information about the customer. They do this through market research, surveys, and face-to-face discussions. Using this information, the salesperson makes a detailed presentation tailored specifically to a consumer’s needs.

More and more sales teams are switching from a narrative or a suggestive approach to a more consultative strategy. As a result, corporations are looking more at intangibles (无形资产) such as creativity and analytical skills and less at educational background and technical skills.

Directions: Read the following passage. Fill in each blank with a proper sentence given in the box.

Each sentence can be used only once. Note that there are two more sentences than you need.

Are Your Clothes Causing Pollution?

Very small pieces of plastic, called microfibers, are polluting rivers and oceans. 1. Clothes worn for outdoor activities and exercise are often made of artificial material, which is useful in keeping warm. But they contain very small plastic fibers, which may also be harming the environment when you wash them. When people wash these clothes, very small pieces go down the drain with the wash water.

Studies on microfibers in the environment

Pollution caused by plastic is not new, but recent studies have shown the effect of microfibers in the environment. Studies show very small microfibers are ending up in our waters, which may come from waste water treatment factories. A 2015 study found them in fish from California.

Microfibers, effect on food supplies

Beyond the waterways, the researchers say microfibers may end up in soil and agricultural lands. 2. This means there is much to be learned about microfibers and the environment. Some studies have shown that microfibers end up inside sea animals, like oysters. 3. Researchers say that the fibers tend not to move into the tissue of the fish, but it needs more study.

Steps to save or keep microfibers from the environment

Until more information becomes known, there are steps to take to reduce the amount of microfibers in the environment. People should use less of the artificial materials. If we already have those in our lives and we’re using them, an important step would be washing them less. 4. A bag is being designed in which to wash these clothes. It traps the microfibers in the bag and it may be available for purchase soon.

A. New technology may a1so help.

B. So if these m icrofiber s have been found in fish and seafood, ar e they safe to eat?

C. They can al so move around the atmosphere.

D. Studies are conducted on how much of the microfibers is released

E. The source of these mi crofibers may surprise you: your clothes.

F. Washing machines keep microfibers from escaping with w ash water
