从供选择的答案中选出应填入下面一段英文中______内的正确答案。 Java was introduced by Sun Microsystems

从供选择的答案中选出应填入下面一段英文中______内的正确答案。

Java was introduced by Sun Microsystems in 1995 and instantly(1)created a new sense of the interactive possibilities ofthe Web. Both ofthe major Web browsers include a Java(2)virtual machine. Almost all major operating system developers (IBM, Microsoft, and others) have added Java(3)compilers as part oftheir product offerings.

The Java virtual machine includes an optional just-in-time compiler that(4)dynamically compiles bytecode into executable code as an alternative to(5)interpreting one bytecode instruction at a time. In many(6)cases, the dynamic JIT compilation is faster than the virtual machine interpretation.

JavaScript should not be(7)confused with Java. JavaScript, which originated at Netscape, is interpreted at a higher level, is easier to learn than Java, but(8)lacks some of the portability of Java and the speed of bytecode. Because Java applets will run on almost any operating system without(8)requiring recompilation and because Java has no operating system-unique extensions or variations, Java is generally regarded as the most strategic(10)language in which to develop applications for the Web.

供选择的答案:

1.confused 2.compilers 3.dynamically 4.requiring 5.cases

6.interpreting 7.language 8.virtual 9.created 10.lacks
