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

Ever since humans have inhabited the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form. of oral speech.
