听力原文： Israel is speeding up construction of its controversial West Bank barrier. The Palestinians say it's a land grab.
Prime Minister Ariel Sharon has ordered quicker work to complete construction of Israel's West Bank separation barrier, especially in the area of Jerusalem. Israel began building the nearly 700 kilometer long barrier two years ago, but only a third has been completed. Israeli officials say that's way too slow.
"Let's just get it done," said Cabinet Minister and former Prime Minister Benjamin Netanyahu."This is a security fence, it is not a political border, it is not meant to keep people in like the Berlin Wall, it is meant to keep terrorists out."
It is not clear how the government will speed up construction of the barrier in light of previous rulings by the Israeli Supreme Court. In the past, the Court has ruled that the government is illegally confiscating West Bank land and creating hardship for Palestinians.
Israeli analyst Dan Schueftan told VOA that many Israelis believe the court is favoring the Palestinians over Israeli security.
"And the more they take decisions in this direction, the more Israelis will question the wisdom of the Supreme Court."
So by ordering rapid construction of the barrier, Mr. Sharon is responding to public opinion. But the Palestinians say it's a land grab.
Palestinian chief negotiator Saeb Erekat: "The only thing that's growing on the ground now is more Israeli settlements, more walls, and more dictations and more harming of the Palestinian people."
The International Court of Justice in the Hague ruled last year that the barrier is illegal and must be torn down. But after more than a hundred suicide bombings during the past four-and-a-half years of conflict, Israel is determined to build the barrier as quickly as possible.
The Israeli Supreme Court has ruled that ______.
A．building West Bank barrier is legal
B．building West Bank barrier is illegal
C．building West Bank barrier is reasonable
D．building West Bank barrier is welcomed

INTERNATIONAL TRANSPORTATION Transportation plays an important part in international business because goods produced have to be delivered to the buyers abroad, and the delivery of goods is to be made possible by transportayion services. Goods are carried by several means of transportation - on road or rail, by sea or air.And in recent years,combined transportation which is a road-sea-rail carriage has appeared. With the expansion of international trade, the container service has become popular. The use of containers provides a highly effective form. of transportation by road, rail and sea. Basically, about 98% of world trade is carried out by sea transportation.Besides transportation by sea, road, or rail, nowadays in order to speed up delivery, carriage by air has also become popular.
1. Transportation plays an important part in international business because goods produced have to be sent to everywhere in the world.()

Too much metal in the soil is considered pollution. Yet too little metal in a person's diet can cause health problems. An American scientist says the answer to both problems may be plants that take up large amounts of metal in their tissues.
David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals.
In recent years, scientists have shown interest in using such plants to clean up harmful waste materials. Professor Salt says such plants also could be used to improve people's diets or even to create foods that fight cancer.
Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is blamed for health problems in many developing countries. Children and pregnant women are mostly affected.
Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that contain minerals needed for good health.
For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants.
Locoweed, which is a common plant in the western U.S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil.
Many people take pills to add important minerals or vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form.
The scientist says his team would like to develop a vegetable crop high in selenium. He wants to create an anti-cancer product in the foods we already eat.
According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______.
A．clean polluted soil and cure disease like cancer
B．clean up harmful waste materials in soil and improve people's diet
C．produce large number of micronutrients such as iron and zinc
D．create food with important minerals or vitamins

•Read the text below about a European rail service and the questions below the passage.
•For each question (13-18), mark one letter (A, B, C or D) on your Answer sheet for the answer you choose.
Success of New Rail Links in Europe
The Eurostar company is now running frequent train services using the tunnel built beneath the sea between Britain and France. Millions of passengers have already travelled on Eurostar trains and there are now twenty services a day between London and Paris and nine between London and Brussels.
Eurostar has already won 40% of all passengers from the UK to Paris and Brussels but further growth will depend on the business market. The early morning departure to Paris is proving popular, especially for business people from London who need to do a full day's work in the French capital.
However. exactly how many of Eurostar's passengers are business travellers is unknown. While first-class accommodation has been 70% fill, many of these passengers are travelling on holiday: one travel agent estimates Eurostar has only 20% of the business travel market. Meanwhile, tour operators report a sharp rise in the sale of short trips to Paris. which, they claim, is largely due to the possibility of travelling by Eurostar.
As Eurostar increases the frequency of daily journeys over the next year. it will need more business travellers than ever to fill its trains. However, business travel agents feel that some aspects of Eurostar service could be improved. According to one large business travel agent. "Eurostar's marketing has been poor and it needs to look more closely at doing commercial deals with large travel agents and corporations to become more attractive than airlines". British travel agents alone are now spending over ￡1 million a month with Eurostar. Naturally, they are expecting Eurostar to provide some good deals and flexible tickets.
Eurostar is hoping to attract more customers as it expands its network of services. Already, train journeys between London and Paris stop at a few towns and cities enroute. There will also be daytime and overnight services front eighteen other British cities to Paris and Brussels, and planning is in progress for services from London to cities in Holland and Germany. Soon, many major towns and cities in Britain and other European countries will have regular direct connections within Eurostar's network.
The demand for Eurostar is forcing airlines to use smaller planes on the London-Paris and London-Brussels service, two of the busiest air routes in the world. One British airline reports a 15% decline in ticket sales to both Paris and Brussels. The crucial marketing aspect in business travel is frequency, Rather than cut frequency, airlines have reduced the size of their aircraft to prevent further losses. However, the large airlines will find it easier to maintain their flight schedules by introducing lower capacity planes. Eurostar threatens mainly the smaller airlines, which already have fewer services and smaller planes.
Which of the following statements is not true about Eurostar company？
A．Passengers can travel on its trains through the tunnel.
B．It offers frequent train services front London to Paris.
C．There are many passengers traveling on Eurostar.
D．It offers a variety of services on the train every day.
