    Are you one of the increasing number of students who are struggling for college education online? Follow these tips to help you be a successful online learner?

Many students assume that online classes require less work and are easier than traditional classes. 1.

Arrangement according to class schedule is important. Log on to your course according to the required schedule. Manage your time just as you would in a traditional course.

2.You may not be able to turn in papers, view videos, or participate in groups if you don't have the proper technology. Make sure that you have the proper Internet connection and software programs installed (安装).

During class, you are advised to be focused. Read and practice everything. 3.Don’t run through a course skipping videos, animations (动画), and ungraded self-assessment activities. Be comfortable communicating through text. Most communication in an online course occurs through the written word. Discussion board posts, written assignments, and email are all common modes of communication in online courses. 4. Be prepared to read and write a lot in online courses.

Remember to be active. If you have questions or don’t understand an assignment, tell your instructor. 5. Don’t wait until after you’ve turned in an assignment to let the instructor know that you have struggled. If you email or call the instructor before an assignment, quiz, or exam, you’ll prevent the struggle, and avoid having your grade suffer.

A.Go through every screen.

B.Online classes require less work

C.You’ll understand the instructor better.

D.Be sure you have the required software and hardware.

E.Your instructor can help you better if you tell him or her.

F.In reality, they’re designed just as demanding as traditional courses.

G.This is different from traditional classes, where a lot of communication is oral.

    If you could change your child's DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR- Cas, or just CRISPR.

CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA; it also uses an enzyme that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.

The uses of CRISPR could mean that cures are developed for everything from Alzheimer's to cancer to HIV. By allowing doctors to put just the right cancer-killing genes into a patient's immune system, the technology could help greatly.

The US' National Academy of Sciences plans to discuss questions about CRISPR s ethics(伦理问题). For example, CRISPR doesn't work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities.

There are also moral questions around playing God. Of course, medicine already stops natural things from happening-for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn't keep going.

Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too; parents might want to make their children more intelligent at all costs.”

In the end, more research is still needed to see what we can and can't do with CRISPR. “It's still a huge mystery how we work,” Craig Mello, a UMass Medical School biologist and Nobel Prize winner, told The Boston Globe, “We're just trying to figure out this amazingly complicated thing we call life.”

A.What we can and can't do with CRISPR.

B.The advantages of CRISPR and arguments about its ethics.

C.How CRISPR was developed by scientists.

D.Scientists' experiments of using CRISPR to edit human embryos.

2.What does the writer mean by saying “playing God” in Para. 5?

A.Playing jokes on religious people.

B.Asking God to help deal with moral questions.

C.Following the instructions of God.

D.Doing things that go against nature.

3.According to the passage, the technology of CRISPR           .

A.is very safe because it only cuts the DNA it is looking for

B.is very helpful to cure people of any disease

C.could cause parents to make unwise choices for their children

D.could help us understand how complicated life is

4.What is the author's attitude towards CRISPR?

A.Objective. B.Worried.

C.Negative. D.Supportive.

    Probably no other musical instrument is as popular as the guitar. Musicians use the guitar for almost every kind of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

Some music experts say an instrument very much like a guitar was played in Egypt more than one thousand years ago. Some other experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the 1700s, it became similar to the instrument we know today.

Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. One kind of music for the guitar developed in the southern area of Spain called Adalusia. It will always be strongly linked with the Spanish guitar. It is called Flamenco.

In the 1930s, Les Paul began experimenting with ways to make an electric guitar. He invented the solid body electric guitar in 1946. The guitar has always been important to blues music. With the electric guitar, Les Paul helped make modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man and his famous guitar. That man is B. B. King. Every blues fan knows that years ago B. B. King named his guitar Lucille. Here B. B. King plays Lucille on his famous recording of “The Thrill Is Gone”. Lucille, B. B. King's large, beautiful black guitar, is important to American music. Visitors can see King's very first guitar at the Rock and Soul Museum in Memphis, Tennessee. The museum is the only permanent exhibit organized by the Smithsonian Institution outside Washington, D. C. , and New York City.

1.Where did the modern guitar finally come into being?

A.Spain. B.Egypt.

C.Persia. D.Italy.
