如何提高SAT閲讀水平

提高SAT閲讀水平的一個必用的方法就是經常找一些SAT閲讀素材進行練習，培養語感和閲讀速度，不懂的詞彙要養成根據上下文的意思進行猜詞的.習慣，之後再查詞典，而不是一開始就查。讀的時候不要一個單詞一個單詞的讀，而是按意羣來閲讀，這樣才有助於你SAT閲讀水平的提高。

There are many unsolved problems in mathematics. Some prominent outstanding unsolved problems include

1. The Goldbach conjecture.

2. The Riemann hypothesis.

3. The conjecture that there exists a Hadamard matrix for every positive multiple of 4.

4. The twin prime conjecture .

5. Determination of whether NP-problems are actually P-problems.

6. The Collatz problem.

7. Proof that the 196-algorithm does not terminate when applied to the number 196.

8. Proof that 10 is a solitary number.

9. Finding a formula for the probability that two elements chosen at random generate the symmetric group .

10. Solving the happy end problem for arbitrary .

11. Finding an Euler brick whose space diagonal is also an integer.

12. Proving which numbers can be represented as a sum of three or four cubic numbers.
