33.Oceanography has been defined as “The application of all sciences to the study of the sea”. Before the nineteen century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.
For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that question “What is at the bottom of the oceans?” had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile (起伏形状) of the route to estimate the length of cable that had to be manufactured.
It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings (测声) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea.
The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.
Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition (考察), which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.
51.The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on ________.
A.an academic aspect B.a military aspect
C.a business aspect D.an international aspect
52.It was ________ that asked Maury for help in oceanographic studies.
A.the American Navy
B.some early intercontinental travelers
C.those who earned a living from the sea
D.the company which proposed to lay an undersea cable
53.The aim of the voyages Maury was responsible for in the 1840s was ________.
A.to make some sounding experiments in the oceans
B.to collect samples of sea plants and animals
C.to estimate the length of cable that was needed
D.to measure the depths of the two oceans
54.“Defied” in the 5th paragraph probably means “________”.
A.doubted B.gave proof to C.challenged D.agreed to
55.This passage is mainly about ________.
A.the beginnings of oceanography
B.the laying of the first undersea cable
C.the investigation of ocean depths
D.the early intercontinental communications

For purposes of this Agreement,the terms defined in the recital of the parties shall
have the meanings given to them therein,the following terms shall have the meanings indicated and the plural form of any term defined herein in the singular shall merely express the grammatical plural of that defined term unless otherwise expressly provided herein.

A relationship is defined as a state of connectedness between people. Although in today’s society with its crazy rhythm of everyday life, when people tend to live in thickly populated cities, spending most of their time in the office and hardly knowing their neighbor’s name, we still find ourselves in some kinds of relationships-with friends, family, or colleagues. Family relationships are the first relationships people enter. Parents and relatives influence our emotional development by creating a model that we are sometimes bound to follow all our lives, often subconsciously （潜意识地）. In day-care, at school, then in the office we spend a lot of time among fellow students and co-workers. We learn to keep business relationships, to work in a team environment, then form smaller groups of like-minded people and finally select some of them as our friends. What is a true friendship? How does it start? Are we destined to become friends with certain people or can we actually plan whom to be friends with？ “Everybody‘s friend is nobody’s.” said Arthur Schopenhauer. Unlike a companionship based on belonging to the same team or group, friendship is a very personal and selective type of relationship. It calls for trust, sincerity, and emotional bonds. Sociologists believe that most people are looking for similarities in views, social status, and interests when choosing friends. No wonder that our friends are often people of the same age, sex, and education. Another important factor is joint activity and solidarity. This is the reason why many of us befriend our colleagues and other people who work in the same field. Most people would agree that a friend is someone who always listens and understands. Understanding in this context implies a lot of meanings-compassion, sympathy, and emotional closeness. It’s a process in which your friend reads your emotional state, shares your feelings, identifies himself or herself with you. 小题1:What is the best title of this passage？_______ A．Family and Relationships B．How to Make Friends with Colleagues C．What is a True Friendship D．People and Relationship 小题2:According to the passage, which of the following affects us most when choosing friends？ A．Kindergarten. B．Family. C．School. D．Office. 小题3: Why are our friends usually of the same age，sex，and education？ A．Because they are clever and well-behaved. B．Because most of us are looking for similarities in views，social status, and interests when choosing friends. C．Because they help us with our work and share our happiness and sorrow. D．Because they cooperate with us well. 小题4:Which of the following statements is NOT true？ A．A companionship is based on belonging to the same team or group. B．Friendship needs trust, sincerity, and emotional bonds. C．Relationships are friendships between people. D．Understanding is a process in which the friend reads our emotional state, shares our feelings, identifies himself / herself with us.

英语翻译
The structure of granules or agglomerates is defined as the spatial
arrangement of its basic components [18].The basic components are
primary particles,binder or liquid components and intra particle
porosity.The quantification of granule structure is crucial for setting
up processing maps and input data for simulations such as DEM and
computational modelling.The used technique should capture at least
the amounts of the basic components.This is especially the porosity of
granules.At a more detailed level,size of the spatial phases is of
interest.Last but not least the distribution through the granule
volume defines its homogeneity and its composite behaviour.
Recently a number of investigators have characterised the internal
granule structure by acquiring internal structure images and analyzing
them by image analysis techniques [15,18–22].
The spatial distribution of elements inside a granule has been
described as the correlation between two points of the same or
different phases in 2D [18].The amount of the constituents,their size
and arrangement quantify the granule structure.These can be
measured by using chord length distribution and covariance function.
The volumetric pore size distribution of a granule inferred from X-ray
images has been estimated by the Faber et al.[19],using an algorithm
described by Russ and Dehoff [23].Kosek et al.[20] used a phase
function,defined by Adler [24] to represent the internal structure of
porous/multiphase media and spatial distribution of phases that form
the medium.By definition,only one phase can be present at any point.
The representation of a structure by means of the phase functions has
several advantages:(i) the phase functions can be obtained from
images of real structures by adjusting the threshold level; (ii) they
bear full information about the spatial distribution of all distinguishable
phases inside the structure; and (iii) they serve as input data for
the evaluation of structure descriptors; (iv) encoding by the phase
functions makes it easy to carry out further simulations of physical
processes that modify the structure,such as drying [25],solidification
[21] or dissolution [15].
A radial grey intensity profile of granules obtained by X-ray has
been presented by Barrera-Medrano et al.[22] as an indication of the
internal structure of granules in 2D space.Barrot et al.[26] have
presented a new method whereby shape descriptors for granular
particles in 3D could be obtained from 2D images,based on the
development of an automated 3D particle shape and structure
synthesis algorithm using a tomographic reconstruction technique.
